I. Introduction

    Electric motors are included in the list of ``covered equipment'' 
for which DOE is authorized to establish and amend energy conservation 
standards and test procedures. (42 U.S.C. 6311(1)(A)). Additionally, 
EPCA directed DOE, subject to a determination of feasibility and 
justification, to establish energy conservation standards and test 
procedure for small electric motors. (42 U.S.C. 6317(b)) DOE's test 
procedures for small electric motors are prescribed at subpart X of 10 
CFR part 431. DOE's test procedures for electric motors are prescribed 
at appendix B to subpart B of part 431. The following sections discuss 
DOE's authority to establish and amend test procedures for small 
electric motors, as well as provide relevant background information 
regarding DOE's consideration of test procedures for this equipment.

[[Page 35469]]

A. Authority and Background

    The Energy Policy and Conservation Act of 1975 (``EPCA'' or ``the 
Act''),\1\ Public Law 94-163 (42 U.S.C. 6291-6317, as codified), among 
other things, authorizes DOE to regulate the energy efficiency of a 
number of consumer products and industrial equipment. Title III, Part C 
of EPCA, which for editorial purposes was re-designated as Part A-1 
upon incorporation into the U.S. Code (42 U.S.C. 6311-6317), 
established the Energy Conservation Program for Certain Industrial 
Equipment, which sets forth a variety of provisions designed to improve 
energy efficiency. This equipment includes small electric motors and 
electric motors, the subject of this RFI. (42 U.S.C. 6317(b) and 42 
U.S.C. 6311(1)(A))
---------------------------------------------------------------------------

    \1\ All references to EPCA in this document refer to the statute 
as amended through the Energy Efficiency Improvement Act of 2015 
(EEIA 2015), Public Law 114-11 (April 30, 2015).
---------------------------------------------------------------------------

    Under EPCA, the energy conservation program consists essentially of 
four parts: (1) Testing, (2) labeling, (3) establishing Federal energy 
conservation standards, and (4) certification and enforcement 
procedures. Provisions of the Act include definitions (42 U.S.C. 6311), 
energy conservation standards (42 U.S.C. 6313), test procedures (42 
U.S.C. 6314), labeling provisions (42 U.S.C. 6315), and the authority 
to require information and reports from manufacturers (42 U.S.C. 6316). 
EPCA includes specific authority to establish test procedures and 
standards for electric motors and small electric motors. (42 U.S.C. 
6313(b), 42 U.S.C. 6314(a)(5) and 42 U.S.C. 6317(b))
    Federal energy efficiency requirements for covered products 
established under EPCA generally supersede State laws and regulations 
concerning energy conservation testing, labeling, and standards. (See 
42 U.S.C. 6316(a) and (b); 42 U.S.C. 6297) DOE may, however, grant 
waivers of Federal preemption for particular State laws or regulations, 
in accordance with the procedures and other provisions of EPCA. (See 42 
U.S.C. 6316(b)(2)(D))
    The Federal testing requirements consist of test procedures that 
manufacturers of covered equipment must use as the basis for: (1) 
Certifying to DOE that their equipment complies with the applicable 
energy conservation standards adopted pursuant to EPCA (See 42 U.S.C. 
6316(a); 42 U.S.C. 6295(s)), and (2) making representations about the 
efficiency of that equipment. (42 U.S.C. 6314(d)) Similarly, DOE must 
use these test procedures to determine whether the equipment complies 
with relevant standards promulgated under EPCA. (See 42 U.S.C. 6316(a); 
(42 U.S.C. 6295(s))
    Under 42 U.S.C. 6314, EPCA sets forth the criteria and procedures 
DOE must follow when prescribing or amending test procedures for 
covered equipment. EPCA generally requires that any test procedures 
prescribed or amended under this section must be reasonably designed to 
produce test results which reflect energy efficiency, energy use, and 
estimated operating costs of a covered equipment during a 
representative average use cycle or period of use and requires that 
test procedures not be unduly burdensome to conduct. (See 42 U.S.C. 
6314(a)(2))
    In addition, if DOE determines that a test procedure amendment is 
warranted, it must publish proposed test procedures and offer the 
public an opportunity to present oral and written comments on them. (42 
U.S.C. 6314(b))
    EPCA also requires that, at least once every 7 years, DOE evaluate 
test procedures to determine whether amended test procedures would more 
accurately or fully comply with the requirements for the test 
procedures to not be unduly burdensome to conduct and be reasonably 
designed to produce test results that reflect energy efficiency, energy 
use, and estimated operating costs during a representative average use 
cycle. (See 42 U.S.C. 6314(a)(1)(A)) If amended test procedures are 
appropriate, DOE must publish a final rule to incorporate the 
amendments. If DOE determines that test procedure revisions are not 
appropriate, DOE must publish its determination not to amend the test 
procedures. DOE is publishing this RFI to collect data and information 
to inform a potential test procedure rulemaking to satisfy the 7-year 
review requirement specified in EPCA, which required that DOE publish, 
by July 07, 2016, either a final rule amending the test procedures for 
small electric motors, or a determination that amended test procedures 
are not required. (See 42 U.S.C. 6314(a)(1))

B. Rulemaking History

    DOE's current test procedure for small electric motors is located 
at 10 CFR 431.444. DOE prescribed test procedures for small electric 
motors on July 7, 2009. 74 FR 32059.\2\ The current test procedures 
incorporate the Institute of Electrical and Electronics Engineers 
(IEEE) Standard 114 and IEEE Standard 112 Test Methods A and B, and CSA 
C747-09 and CSA C390-10 as alternative test procedures. (See 10 CFR 
431.444(b))
---------------------------------------------------------------------------

    \2\ On May 4, 2012, DOE made clarifying edits and updates to the 
test procedures and provided procedures for DOE designation of 
nationally recognized certification programs. 77 FR 26608.
---------------------------------------------------------------------------

    On June 24, 2016, DOE published a separate notice of proposed 
rulemaking regarding the certification, compliance, labeling, and 
enforcement of energy conservation standards for electric motors and 
small electric motors. 81 FR 41378 (June 2016 CCE NOPR). In the June 
2016 CCE NOPR, DOE proposed to bring certification, compliance, and 
enforcement (CCE) regulations for electric motors and small electric 
motors under the general regulatory scheme of DOE's existing 
certification, compliance, and enforcement regulations for other 
covered products and equipment. See id. Additionally, the June 2016 CCE 
NOPR proposed specific sampling plans, certification of efficiency 
requirements, independent testing laboratory and certification program 
requirements, and labeling requirements for electric motors and small 
electric motors. See id.

II. Request for Information and Comments

    In the following sections, DOE has identified a variety of issues 
on which it seeks input to aid in considering whether or not new or 
amended test procedures for small electric motors. Specifically, DOE is 
requesting comment on any opportunities to streamline and simplify 
testing requirements for small electric motors.
    Additionally, DOE welcomes comments on other issues relevant to the 
conduct of this process that may not specifically be identified in this 
document. In particular, DOE notes that under Executive Order 13771, 
``Reducing Regulation and Controlling Regulatory Costs,'' Executive 
Branch agencies such as DOE are directed to manage the costs associated 
with the imposition of expenditures required to comply with Federal 
regulations. See 82 FR 9339 (Feb. 3, 2017). Pursuant to that Executive 
Order, DOE encourages the public to provide input on measures DOE could 
take to lower the cost of its regulations applicable to small electric 
motors consistent with the requirements of EPCA. DOE also requests 
comment on the benefits and burdens of adopting any industry/voluntary 
consensus-based or other appropriate test procedure, without 
modification.

A. Equipment Categories Considered in This Request for Information

    1. DOE is considering revising the test procedures for small 
electric motors and establishing new test procedures for electric 
motors beyond those currently subject to existing test procedures.

[[Page 35470]]

Sections II.A.1 and II.A.2 describe both of these categories. Small 
Electric Motors
    DOE regulations define ``electric motor'' as a machine that 
converts electrical power into rotational mechanical power. 10 CFR 
431.12. EPCA defines the term ``small electric motor'' as a NEMA 
general-purpose alternating current single-speed induction motor, built 
in a two-digit frame number series in accordance with National 
Electrical Manufacturers Association (NEMA) Standards Publication MG 1-
1987 (MG 1 1987). (42 U.S.C. 6311(13)(G))
    Subpart X of 10 CFR part 431 includes test procedures for the three 
topologies of small electric motors: Capacitor-start induction-run 
(CSIR), capacitor-start capacitor-run (CSCR), and certain polyphase 
motors. In any potential rulemaking, DOE will consider amendments to 
the test procedures for a ``small electric motor'' as defined at 10 CFR 
431.442. Were DOE to determine that a motor did not meet the EPCA 
definition of ``small electric motor'' and, therefore, is not subject 
to test procedures in subpart X of 10 CFR part 431, DOE may determine 
that such a motor would still be considered for test procedures as an 
``electric motor.'' \3\
---------------------------------------------------------------------------

    \3\ While the motors discussed in this RFI are likely covered as 
``electric motors,'' DOE is authorized to determine whether ``other 
motors'' are to be included as covered equipment and subject to 
standards. (See 42 U.S.C. 6311(2)(B)(xiii); 42 U.S.C. 6312(b))
---------------------------------------------------------------------------

2. Motors Categories Not Currently Subject to Test Procedures
    DOE may consider setting test procedures for motors that are 
considered ``small'' by customers and the electric motor industry, but 
are not currently subject to the small electric motor test procedures. 
These motors may have similarities to motors that are currently 
regulated as small electric motors (such as horsepower) and may be used 
in similar applications. However despite these similarities, DOE is 
still determining whether these motors would be regulated as small 
electric motor or as electric motors under DOE regulations.
    Regardless of the category under which they are regulated, if test 
procedures are adopted for these motors, DOE would define those 
categories (and exemptions) using technical and physical 
characteristics of those motors. DOE expects that this approach would 
describe the applicability of test procedures to particular motors 
without reference to statements of marketing or design intent.
    In order to identify whether test procedures should be considered 
for additional motors, DOE is first reviewing which motors are and are 
not already subject to regulations. Motors of enclosed construction, 
non-continuous duty, and not meeting certain torque requirements are 
not addressed by the regulations in subpart B or subpart X of 10 CFR 
part 431. DOE may consider setting test procedures for some of these 
motors. Table II-2 lists the motor topologies that may be considered 
for test procedures.
    Section 431.25 to subpart B of 10 CFR part 431 subjects certain 2-
digit NEMA frame (56-frame) polyphase motors of enclosed construction 
and certain 3-digit polyphase motors to energy conservation standards. 
The electric motors regulated at 10 CFR 431.25 currently exclude two 
groups of motors: (1) Those with less than one horsepower and (2) 
polyphase motors of a 2-digit frame size (other than certain NEMA 56-
frame size enclosed motors) with a horsepower greater than or equal to 
one. DOE may consider establishing test procedures for some of these 
motors with the intent is to primarily focus on motors considered small 
by customers and industry.
    Only motors with a power rating of greater than or equal to 0.25 
horsepower and less than or equal to 3 horsepower are subject to the 
regulations in subpart X to 10 CFR part 431. Should DOE consider a 
potential test procedure rulemaking, DOE does not expect at this time 
that it would propose revisions to the test procedures for polyphase 
enclosed motors greater than or equal to one horsepower in the NEMA 56-
frame size because some of these motors are currently regulated in 
Sec.  431.25 of subpart B to 10 CFR part 431.
    If DOE determines to propose test procedures for categories of 
motors not currently subject to test procedures, DOE will reconsider a 
lower horsepower limit. Upon reviewing manufacturer catalogs, DOE found 
that the lowest horsepower with multiple manufacturers offering a wide 
range of motors was 0.125 hp. DOE will consider a minimum horsepower 
limit in any potential rulemaking.
    Similarly, DOE would consider an upper horsepower limit in any 
rulemaking. The 3 hp upper limit for single-phase motors is based on a 
2006 determination that DOE intends to review. 71 FR 38799 (July 10, 
2006). DOE has since found that single-phase, 2-digit NEMA frame size 
motors that exceed 3 hp are available, along with single-phase motors 
inclusive of all frame sizes with up to 15 hp. DOE also found that 
polyphase 2-digit NEMA frame size motors, excluding those currently 
regulated at 10 CFR 431.25, exist up to 5 hp.
    Based on the existing definitions discussed above, Table II-1 lists 
the motor categories, by horsepower and frame size, that may be 
considered for test procedures in any rulemaking. Frame size is not 
used as a limiting factor except in the case of polyphase motors for 
purposes of preventing overlap with the electric motors regulations 
listed at 10 CFR 431.25. The final list of motors subject to test 
procedures may be more limited than Table II-1 based on properties 
other than horsepower and frame size, as discussed later in this 
section.

  Table II-1--Motors Under Consideration for a Potential Test Procedure
                               Rulemaking
------------------------------------------------------------------------
          Phase count                Horsepower           Frame size
------------------------------------------------------------------------
Single.........................  >=0.125 hp and      All.
                                  <=15 hp.
Polyphase......................  >=0.125 hp and <=5  2-digit.*
                                  hp.
Polyphase......................  <1 hp.............  All.
------------------------------------------------------------------------
* Polyphase enclosed motors >=1 hp, of the 56-frame size are not under
  consideration for revised test procedures, as certain ones of these
  motors were included in a separate rulemaking, and are regulated at 10
  CFR 431.25.

    A variety of motor topologies exist within the range described in 
Table II-1, including topologies (e.g., polyphase) that meet the 
regulatory definition of small electric motor and others (e.g., shaded 
pole) that are not currently regulated as small electric motors or 
electric motors. DOE may use a subset of these motor topologies to 
describe the

[[Page 35471]]

motors subject to test procedures in a potential final rule. Table II-2 
lists various categories of motors that could potentially be considered 
for test procedures within the motor horsepower and frame sizes 
outlined in Table II-1. Certain subcategories of the motors listed in 
Table II-2 meet the definition of ``small electric motor'' and are 
subject to regulations at subpart X of 10 CFR part 431. Table II-3 
presents a shorter list of categories of motors that DOE has 
preliminarily identified as representing potential interest because of 
their volume of shipments, ability to be tested using existing test 
procedures, and energy consumption.

    Table II-4 lists various mechanical, electrical, and other design 
characteristics of motors such as the ability to operate submerged in a 
liquid (i.e., submersible motors). DOE may rely on some of these design 
characteristics to describe the categories of motors that would be 
considered in a potential test procedure rulemaking.

------------------------------------------------------------------------

    The existing regulations for electric motors apply to a subset of 
electric motors characterized by nine design elements listed at 10 CFR 
431.25(g), with the exceptions listed at 10 CFR 431.25(l). DOE could 
consider establishing a similar list of characteristics to delimit the 
categories of motors included in any potential small electric motor 
rulemakings, such as:
    (1) Horsepower;
    (2) Number of speeds (single, multiple, continuously variable);
    (3) Motor topology;
    (4) Duty rating;
    (5) Enclosure construction;
    (6) 60 hertz (Hz) sinusoidal power for alternating current (AC) 
motors;
    (7) Input waveform (either AC or direct current (DC));
    (8) Phase count (single-phase, polyphase);
    (9) Frame size; and
    (10) Other criteria presented in Table II-4.
    Motors can have different speed capabilities, including single, 
multi, or (continuously) variable speeds. Variable and multi-speed 
motors can be tested with existing industry standards (see Table II-6) 
at a variety of operating points, but no single metric currently exists 
to quantify the performance of the variable or multi-speed motor. 
Variable or multi-speed capability provides the ability to save energy 
by more closely matching motor output to a varying load. DOE is 
considering whether to consider all speed capabilities in setting any 
potential new test procedures.
    Motors can also have different topologies as listed in Table II-2. 
DOE has found test procedures that apply to all of these topologies for 
both induction and non-induction motors (see section II.C.1). Non-
induction motors (such as permanent magnet motors) are often marketed 
as more efficient substitutes for induction motors, but currently have 
a lower market share. DOE is considering whether all motor topologies 
would be analyzed for potential new test procedures.
    Motors can be described by their duty type, using either NEMA or 
IEC nomenclature. Duty type describes the operating profile the motor 
is designed to handle. For example, a continuous duty motor can operate 
for long periods of time at a steady load between required shut-down 
periods while intermittent-duty motors accumulate fewer annual 
operating hours Similar to the electric motors regulations described in 
subpart B of 10 CFR part 431, DOE is considering analyzing only 
continuous duty type motors for potential test procedures. DOE will 
consider whether any IEC duty types other than IEC duty type S1 
correspond to a continuous duty type. For example, IEC duty types S9 
and S10 can include an S1 reference rating, and may also be operated 
continuously.
    Motors can be described by their enclosure construction--i.e. open 
and enclosed--and by many subcategories (e.g., open drip proof, totally 
enclosed non-ventilated, and totally enclosed air-over). Enclosure 
construction tends to describe both the level of ingress protection 
(i.e., protection from dust or splashing) and the cooling method (such 
as active air cooling via an integral fan or passive cooling via 
natural convection). Similar to the electric motors regulations 
described in subpart B of 10 CFR part 431, DOE is considering analyzing 
all enclosure constructions for potential new or revised test 
procedures.
    An ``air-over'' motor is a unique variety of enclosure construction 
relating to a cooling method in which the motor is cooled by an 
airstream provided by a device or system separate from the motor. At 
the time of the December 2013 electric motors test procedure final 
rule, DOE lacked the necessary data to develop a test procedure for 
air-over motors. 78 FR 75973-75975 (December 13, 2013). As discussed in 
section II.C.1, DOE is investigating the potential to establish a test 
procedure for air-over motors.
    A revised definition of air-over motor based on the physical 
features of a given motor may be needed to support potential test 
procedure. As part of the December 2013 electric motors test procedure 
final rule, DOE defined the term ``air-over electric motor'' as an 
electric motor rated to operate in and be cooled by the airstream of a 
fan or blower that is not supplied with the motor and whose primary 
purpose is providing airflow to an application other than the motor 
driving it. 78 FR 75973-75975. In other words, air-over electric motors 
do not have a factory-attached fan and require a separate means of 
forcing air over the frame of the motor. However, DOE notes that the 
absence of a fan is not a differentiating feature as some motors 
categories, such as totally-enclosed non-ventilated (TENV) motors, do 
not have internal fans or blowers. In terms of physical construction, 
DOE did not find any differences between air-over motors and non-air-
over motors. For example, there is little difference between a totally-
enclosed fan-cooled motor (TEFC) and a totally-enclosed air-over motor 
(TEAO). Based on these observations, DOE understands that what 
differentiates air-over motors from non-air-over motors is that they 
require the application of external cooling by a free flow of air to 
prevent overheating during continuous operation. In a TEAO, without the 
application of free flowing air, the internal motor winding 
temperatures would exceed the maximum permissible temperature. The risk 
of overheating can be verified by observing whether the motor's 
temperature rises during a rated load temperature test instead of 
stabilizing. During a rated load temperature test the motor is loaded 
at the rated full load using a dynamometer until it is thermally 
stable. The current industry standards incorporated by reference in the 
existing DOE small electric motors test procedure each contain a 
portion describing a rated load temperature test. Thermal stability is 
defined as the condition where the motor temperature does not change by 
more than 1 [deg] Cover 30 minutes or 15 minutes depending on the motor 
category (See section 5.8.4.4 of IEEE \4\ Std 112-2004, (IEEE 112-
2004), ``IEEE Standard Test Procedure for Polyphase Induction Motors 
and Generators,'' and section 10.3.1.3 of IEEE Std 114-2010, (IEEE 114-
2010), ``IEEE Standard Test Procedure for Single-Phase Induction 
Motors''). DOE further notes that specifying that the external cooling 
is obtained by a free-flow of air differentiates air-over motors from 
other totally-enclosed pipe-ventilated motors. Based on these findings, 
DOE is considering defining an air-over motor as a motor that does not 
thermally stabilize without the application of external cooling by a 
free flow of air

    AC motors are designed to operate at a particular frequency. In the 
United States, AC power is delivered at 60 Hz. For this reason, DOE is 
considering whether to continue to limit the scope of a potential test 
procedure to only AC motors that are designed to operate at 60 Hz. DOE 
notes that this approach includes motors designed to operate at 60 Hz 
that are also capable of operating at other frequencies (e.g., 50 Hz).
    Motors can be designed to operate at an input waveform of AC or DC. 
DOE has found test procedures that apply to both AC and DC motors. DC 
motors must be fed a DC waveform, but some DC motors are advertised as 
substitutes for AC motors because a rectifier can be placed between the 
AC power source and the DC motor to convert the AC power to DC. In many 
cases, the rectifier may be integrated with the motor, creating a drop-
in replacement for AC motors (i.e., it can be used with the existing AC 
power supply). DOE is considering whether DC motors should be analyzed 
in a potential test procedure rulemaking.
    Motors also are constructed with a particular frame size. Frame 
size most commonly refers to a height measurement between the 
centerline of the shaft and the bottom of the feet, but can also 
describe a motor's axial length. NEMA frame sizes are described in 2-, 
3-, and 4-digit naming conventions. DOE has established regulations for 
small electric motors built in two-digit frame number series according 
to NEMA MG 1-1987 (i.e., 42-, 48-, and 56-frame motors), and IEC 
equivalents. DOE is aware of motor topologies in Table II-3 within the 
horsepower ranges in Table II-1 that are available in additional frame 
sizes (e.g., 3-digit). Due to the availability of additional frame 
sizes for topologies and horsepower ratings that may be considered for 
test procedures in a potential rulemaking, DOE is considering not using 
frame size or the frame size naming convention (NEMA digit count) as a 
means of limiting the categories of motors analyzed for a potential 
rulemaking, to the extent that this would not overlap with existing 
regulations for electric motors at 10 CFR 431.25.
    Issue 1: DOE seeks comment, data, information and justification 
regarding a minimum and maximum horsepower limit for motors for which 
DOE may consider test procedures.
    Issue 2: DOE seeks comment, data, and information about any 
additional motor category and associated horsepower range, frame sizes, 
and/or any additional features (such as voltage and service factor) 
that should be considered in a possible test procedures rulemaking and 
why (e.g., motor categories and features presented in Table II-1, Table 
II-2, Table II-3, and Table II-4). DOE is also interested in detailed 
information on whether there would be a significant test burden 
resulting from requiring testing of such motors--and if so, the nature 
and extent of that burden.
    Issue 3: DOE requests comment on the primary motor topologies 
included in Table II-3, including whether they should be considered, or 
not, in a possible test procedures rulemaking and why. DOE seeks 
comment on any motor topologies not listed that DOE should consider 
including in a possible test procedures rulemaking. DOE is interested 
in information on the potential test burden associated with testing 
such motors.
    Issue 4: DOE seeks input on how an air-over motor could be 
identified based on physical and technical features. DOE requests 
comment on whether air-over motors could be defined based on their 
inability to thermally stabilize without the application of external 
cooling by a free flow of air during a rated temperature test according 
to either IEEE 112-2004, CSA C747-09, or CSA C390-10 for polyphase 
motors; or IEEE 114-2010 or CSA C747-09 for single-phase motors. In 
addition, DOE requests comment and information on whether all motors 
currently sold as ``air-over motors'' and which percentage of the 
market would meet this definition.
3. Exemptions
    In a potential future rulemaking, any exemption from test 
procedures would likely be based on specific physical or design 
criteria that can be identified at the point of manufacture (e.g., 
frame size, enclosure, service factor), and not on the advertised 
application of the motor. DOE would consider whether the exemptions 
from the existing regulations for electric motors at 10 CFR 431.25(h)-
(j) would also apply to the motors under consideration for regulation 
in a potential test procedure rulemaking. These exemptions, outlined at 
10 CFR 431.25(l), are as follows:
     Air-over electric motors;
     Component sets of an electric motor;
     Liquid-cooled electric motors;
     Submersible electric motors; and
     Inverter-only electric motors.
    DOE adopted definitions for ``air-over electric motors,'' 
``component sets,'' ``liquid-cooled electric motors,'' ``submersible 
electric motors,'' and ``inverter-only electric motors'' at 10 CFR 
431.12. If DOE undertakes a test procedure rulemaking, it will evaluate 
the merits of adopting similar definitions and exemptions for motors 
with similar features. DOE will further investigate whether these 
categories of motors exist within the range of motors considered in any 
such rulemakings. For liquid-cooled, inverter-only, and submersible 
motors, DOE reviewed online manufacturer catalogs and one distributor's 
Web site and found at least one model corresponding to each of these 
three categories of motors that was within the horsepower ranges and 
frame sizes described in Table II-1.
    Issue 5: DOE seeks comment, data, and information about any motor 
category that should be considered for exemption from a possible test 
procedure rulemaking and information providing justification for such 
exemptions. All exemptions, including exemptions targeted for motors 
that serve specific applications (e.g., submersible motors), must be 
identified based on unique physical features of the motor. DOE seeks 
comment, data, and information on these physical features.
4. Motor Boundary
    An electric motor is a device that converts electrical power into 
rotational mechanical power. Some motors may modify the electrical 
input via rectification, inversion, or other processes prior to 
generating a magnetic field within the motor. This electrical 
conversion process can take place via a device integrally connected to 
the motor, or via a device wired in-line between the power source and 
the motor. In a potential rulemaking, DOE plans to specify which 
components (e.g., rectifiers, inverters) would be subject to 
consideration for the test procedure.
    One example of a motor that includes electrical conversion is a DC 
brushless permanent magnet motor (commonly referred to as an 
electronically commutated motor [ECM]). Typically, the DC brushless 
permanent magnet motor is connected to AC power. The AC power is 
rectified into DC and inverted to a new waveform (e.g., a rectangular 
waveform) that is then fed to the motor via electronic commutation.

[[Page 35474]]

While typically integral to the motor, this design could be implemented 
with the rectification and inversion either integral to or separate 
from the motor. DOE is considering defining such categories of motors 
as including all components essential to operating the motor. For 
motors that can be operated with and without non-integrally connected 
controls or electrical conversion devices, DOE may consider testing in 
each arrangement depending on which motor categories are included in 
any potential new and/or revised test procedure.
    Issue 6: DOE requests comment on how to account for components 
included in a motor for motors that are sold in multiple pieces, 
specifically regarding how to categorize controls or electrical 
conversion components that may be non-integrally connected to the motor 
and how to treat them during testing. DOE requests comment on ways to 
identify control and conversion components that are essential to motor 
operation.
    Issue 7: DOE seeks comments and feedback about whether the presence 
of a gear box should constitute a new motor model when added to a 
motor. More specifically, if DOE were to establish a test procedure for 
motors with gear boxes, should these motors have to be certified to DOE 
separately from the same motors without a gear box? DOE is interested 
in information regarding the potential test burden should separate 
certification be required. Does the gear box change the tested motor 
efficiency?
5. Motors Used in Dedicated Purpose Pool Pumps
    Although motor regulations currently apply to certain small 
electric motors (subpart X of 10 CFR part 431) and electric motors 
(subpart B of 10 CFR part 431), regulations do not cover certain 
varieties of motors that are used in pool pump applications. For 
example, enclosed motors of less than one output horsepower are not 
subject to the current test procedure or energy conservation standards, 
nor are multispeed motors.
    The issue of the efficiency of electric motors used in dedicated 
purpose pool pumps (DPPP) was brought up by several stakeholders in 
comments submitted in response DOE's direct final rule for DPPPs. 82 FR 
5650 (January 18, 2017). Several manufacturers suggested that an energy 
conservation standard for the motors used in DPPPs was needed in 
addition to the standards for DPPPs themselves. This included a 
manufacturer of the motors used in pool pump applications, Regal Beloit 
Corporation, manufacturers of pumps, Hayward Industries, Inc. and 
Pentair Water Pool and Spa, Inc., and a manufacturer of pool equipment, 
Zodiac Pool Systems, Inc. (EERE-2015-BT-STD-0008, Regal, No. 122 at pg. 
1; Hayward, No. 125 at p. 1; Pentair, No. 132 at pp. 1-2; Zodiac No. 
134 at pp. 1-2). Other commenters also argued for a specific pool pump 
motor standard, including the California Investor Owned Utilities (CA 
IOUs), the industry trade association (Association of Pool and Spa 
Professionals (APSP)), and two policy advocacy organizations (the 
Appliance Standards Awareness Project (ASAP) and the Natural Resources 
Defense Council (NRDC)). (EERE-2015-BT-STD-0008; CA IOUs, No. 130 at p. 
2; APSP, No. 127 at p. 2; ASAP No. 133 at pp. 4-5; NRDC No. 121 at p. 
4). In response to these comments, DOE published a notice announcing a 
public meeting pertaining to potential energy conservation standards 
for DPPP motors. 82 FR 30845 (July 3, 2017). In order to consider the 
need for a specific pool pump motor regulations, DOE is requesting 
information on the physical characteristics of motors used in pool pump 
applications and any applicable test procedures that DOE should 
consider.
    Issue 8: DOE is interested in any physical feature(s) or observable 
physical properties that would differentiate these motors from the 
currently regulated small electric motors at 10 CFR 431.446 and 
electric motors at 10 CFR 431.42525 that would help define the scope of 
applicability of the test procedure should DOE decide to proceed in 
consideration of one.
    Issue 9: DOE also requests comment on any particular markings or 
labels applied to these products or if there are published industry 
standards that may be used to uniquely identify motors used in pool 
pump applications, for example sections of NEMA MG 1-2014, ``Motors and 
Generators,'' or of UL 1801, ``Standard for Swimming Pool Pumps, 
Filters, and Chlorinators'' and would help define how they should be 
tested.

B. Metric

    The existing small electric motor test procedure uses motor average 
efficiency at full-load as the metric. 10 CFR 431.444. A manufacturer 
of small electric motors must determine the average efficiency, at 
full-load, of a basic model through testing and applying a sampling 
plan; or through the use of alternative methods for determining energy 
efficiency or energy use (also known as alternative efficiency 
determination methods, or ``AEDMs''). 10 CFR 431.445. For electric 
motors, the existing test procedure uses the metric nominal full-load 
efficiency. Provisions for determining a basic model's efficiency 
through testing or with an AEDM are currently described in 10 CFR 
431.17.
    In a potential test procedure rulemaking, DOE could evaluate 
whether to use the same metric and establish the performance of small 
electric motors and newly regulated motors based on their tested 
average full-load efficiency or whether to use a different metric, such 
as a metric based on motor full-load losses. The sampling plan small 
electric motor manufacturers must use to make representations of 
average full-load efficiency is discussed in section II.C.3 in this 
RFI.
    Issue 10: DOE requests comment on the existing small electric motor 
and electric motor metrics and on any recommended new metrics for the 
motors under consideration in a test procedure rulemaking.

C. Test Procedures

    Pursuant to EPCA's requirement that DOE review a given test 
procedure at least once every 7 years, DOE will undertake a test 
procedure review.
1. Method
    DOE plans to (1) determine if the existing DOE test procedure 
requires revisions, and (2) determine whether new test procedures for 
any new motors identified in section II.A are needed (3) determine 
whether any new motors identified in section 11.A should be categorized 
as small electric motors or as electric motors are needed. If DOE 
develops test procedures for any new motors, it would consider either 
(1) adding testing instructions that modify the test methods currently 
incorporated by reference at 10 CFR 431.443, or (2) establishing new 
methods based on industry standards not currently incorporated by 
reference in 10 CFR 431.443.
    The existing test procedure for small electric motors is codified 
at 10 CFR 431.443, 10 CFR 431.444, and 10 CFR 431.445. The referenced 
industry standards for each motor category are shown in Table II-5 in 
this RFI.

------------------------------------------------------------------------

    DOE reviewed existing industry standards from the IEEE, the CSA 
Group, and the International Electrotechnical Commission (IEC) and 
found existing test methods for all other motor topologies that DOE may 
consider in future regulations (see Table II-6). However, the existing 
test procedure may not apply to all existing mechanical designs or 
electrical features within a given motor category (e.g., motors with 
air-over enclosures, which otherwise meet the definition of small 
electric motors or electric motors but fall outside the scope of IEEE 
112-2004). DOE plans to consider amending the existing test procedure 
to address potential new motor categories.
    For air-over motors specifically, DOE plans to investigate testing 
instructions that would allow testing based on the same industry 
standards incorporated by reference at 10 CFR 431.443. In the past, as 
part of the December 2013 electric motors test procedure final rule, 
DOE investigated possible methods to test air-over electric motors and 
determined that it did not have sufficient information to overcome the 
practical challenges associated with testing air-over motors, such as 
providing a standard flow of cooling air from an external source that 
provides a constant velocity over the tested motor under defined 
ambient temperature and barometric conditions. Therefore, at the time, 
DOE did not establish any test methods for air-over motors. 78 FR 
75926, 78 FR 75962, 75973-75975 (December 13, 2013).
    DOE reviewed section 8.2.1 of IEEE 114-2010 and section 5 of CSA 
C747-09, which include provisions for testing air-over single-phase 
motors. Typically, the measurements according to these test standards 
are performed when the tested motor's winding is thermally stable.\6\ 
Because the windings of air-over motors would overheat without an 
external airflow and degrade the motor, both test methods include 
specific provisions for air-over motors. Both test methods require test 
measurements to be performed with sufficient ventilation to maintain a 
temperature within 70 [deg]C-80 [deg]C, therefore removing the need to 
accurately measure airflow by specifying a temperature range for the 
motor's winding instead. Because the motor winding temperature is 
inversely correlated to efficiency, a target winding temperature range 
is specified to enable relative comparability of efficiency for air-
over motors. This temperature range (70-80 [deg]C) was originally 
selected by CSA as it would reflect a winding temperature range that 
mimics the field operating conditions for air-over motors.\7\
---------------------------------------------------------------------------

    \6\ A rated load temperature test is a test during which the 
motor is loaded at the rated full-load by means of a dynamometer 
until it is thermally stable. Thermal stability is defined as the 
condition where the motor temperature does not change by more than 1 
[deg]C over 30 min or 15 min depending on the motor category (See 
section 5.8.4.4 of IEEE 112-2004 and section 10.3.1.3 of IEEE 114-
2010)
    \7\ Additionally, DOE reviewed 366 single-phase, air-over motor 
models from five major motor manufacturers and observed the 
following distribution across insulation classes: A (1.5 percent); B 
(85 percent), F (13 percent); and H (0.5 percent). An insulation 
class B corresponds to a winding temperature of 75 [deg]C according 
to Table 2 of IEEE 114-2010.
---------------------------------------------------------------------------

    NEMA published an air-over efficiency test standard which provides 
three testing methods for measuring the efficiency of single phase and 
polyphase air-over motors (NEMA Air-over Motor Efficiency Test 
Method).\8\ Each test method requires a temperature test before 
performing the efficiency test according to the applicable test 
standard \9\ and replaces the original temperature test portion of the 
applicable efficiency test. Although each of the three methods require 
the temperature test to be conducted differently,\10\ the document 
describes the three testing methods as equivalent.
---------------------------------------------------------------------------

2017. Available at http://www.nema.org/Standards/Pages/Motors-and-Generators.aspx.
    \9\ IEEE 114-2010, IEEE 112-2014, CSA C390-10, or CSA C747-09, 
depending on the motor phase and rated motor horsepower.
    \10\ The NEMA Air-over Motor Efficiency Test Methods describes 
three temperature tests conducted by (1) thermally stabilizing while 
applying an air-flow based on customer specification; (2) bringing 
the air-over motor at full-load within 10 [deg]C of a target 
temperature using external cooling air (the target temperature for 
single phase motors is 75 [deg]C, while the target temperature for 
polyphase motors varies depending on the motor's insulation class); 
or (3) bringing the air-over motor at a reduced load condition to 
within 10 [deg]C of the target temperature without using external 
cooling air.
---------------------------------------------------------------------------

    DOE intends to review these test methods, and evaluate whether a 
similar approach for testing single-phase and polyphase air-over motors 
should be considered. DOE will also review the possibility of testing 
polyphase air-over motors using different target temperatures depending 
on the air-over motor's insulation class for polyphase motors.
    DOE also is evaluating possible test procedures for motors with 
non-standard construction. These motors, which otherwise meet the 
definition of small electric motors, include motor variants such as 
motors with special shaft dimensions, motors with brakes, or motors 
with vertical mounting. For these motors, DOE plans on reviewing the 
applicability of the testing instructions in section 4 of appendix B to 
subpart B of part 431.
    Finally, DOE is also evaluating potential test procedures for 
synchronous motors. Specifically, DOE will evaluate the industry 
standards applicable to synchronous motors in Table II-6. DOE will 
consider each test procedure with respect to any proposed scope of 
applicability (e.g., motor horsepower limits). For example, CSA C747-09 
has a scope of 0.186 kW to 0.746 kW (0.25 hp to 1 hp), and IEEE Std 
115-2009, (IEEE 115-2009), ``IEEE Guide for Test Procedures for 
Synchronous Machines,'' applies to larger than fractional horsepower 
motors (i.e., greater than or equal to 1 hp); therefore, if the 
proposed scope of applicability of a test procedure spanned both 
industry standards, DOE would consider whether each industry standard 
was appropriate and would determine how to specify which industry 
standard applied to various synchronous motors. DOE, however, is 
uncertain as to the applicability of IEEE 115-2009 to AC permanent 
magnet synchronous and reluctance synchronous motors, one of the 
synchronous motor topologies in Table II-6 in this RFI.

    Issue 11: DOE seeks comment and information on whether and why the 
existing test procedure for determining the average full-load 
efficiency of small electric motors requires revision, and, if so, what 
these revisions should be. DOE also requests comment on the impact to 
test burden from any suggested revisions.

methods for testing other topologies (motors other than CSCR, CSIR, and 
polyphase) listed in Table II-6 in this RFI. If a new test procedure is 
needed, DOE requests information on any additional instructions that 
would be required to test these motor topologies.
    Issue 13: DOE requests comment on any other design features of a

testing, what these modifications should be, and why. In particular, 
DOE requests comment on whether testing instructions similar to the 
ones found in section 4 of appendix B to subpart B of part 431 would 
apply to any new motors that may be included in a possible test

testing provisions for air-over motors in section 8.2.1 of IEEE 114-
2010, section 5 of CSA C747-09, and in the NEMA Air-over Motor 
Efficiency Test Method. Specifically, DOE requests feedback and 
supporting data on the repeatability and level of accuracy of these 
methods, and on whether these or other methods would lead to equivalent 
results when applied to the same motor.
    Issue 15: DOE understands that customers may provide air-velocity 
specifications for air-over motors. DOE requests comment on whether 
testing air-over motors according to customer air-velocity 
specifications is currently used by the industry and why. Additionally 
DOE requests comment on whether testing air-over motors according to 
customer air-velocity specifications would allow comparability of 
efficiency across motors.
    Issue 16: DOE is aware that, because efficiency is inversely 
correlated to temperature, conducting the temperature test using a 
different target temperature for polyphase air-over motors depending on 
the motor's insulation class may lead to measured efficiency values 
that are not comparable across insulation classes. When measuring 
polyphase air-over motor efficiency, DOE requests comment on whether 
the temperature test should be conducted using a single target 
temperature in order to allow relative comparability of polyphase air-
over motor efficiency across insulation classes. If not, DOE requests 
comment on a justification for why testing polyphase air-over motors 
using a temperature test at different target temperatures depending on 
the motor's insulation class would still provide comparable efficiency 
results across insulation classes.
    Issue 17: DOE also requests comment regarding any additional 
instructions for testing electronically commutated motors or other 
categories of motors with controls (e.g., variable-speed drives), and 
how controls affect average full load efficiency of the motor.
    Issue 18: DOE requests comment on industry standards applicable to 
synchronous motors and their applicability to the horsepower range 
(i.e., >=0.125 hp and <=15 hp) that DOE is considering in a potential 
test procedure rulemaking (e.g., IEEE 115-2009, IEEE 1812-2014, IEC 
60034-2-1: 2014, and CSA C747-09). DOE also requests comment on the 
applicability of IEEE 115-2009 to AC permanent magnet synchronous and 
synchronous reluctance motors.
    Issue 19: DOE requests comment on the feasibility of testing motors 
that are components of other equipment. Specifically, DOE requests 
comments on whether some motors that only enter commerce as components 
of another product require modifications to an industry standard for 
testing and on what these modifications should be and why.
    Issue 20: DOE requests comment and supporting data on testing times 
and associated costs of efficiency testing. Specifically, how many 
hours it takes to test a motor per each industry standard listed in 
Table II-6, if manufacturers test their own models or hire a third-
party for testing, if manufacturers need to purchase additional test 
equipment according to the industry standards in Table II-6, and if 
there are any other costs associated with testing.
    Issue 21: DOE requests comment on the benefits and burdens of 
adopting any already existing voluntary consensus-based or other 
appropriate test procedure, without modification.
2. Motor Horsepower
    As part of the potential test procedure rulemaking, DOE is 
considering establishing a method to determine the load point for 
testing a motor under full-load (i.e., rated motor horsepower). Rated 
motor horsepower is generally not an intrinsic, observable motor 
property, but rather it is declared by the

[[Page 35477]]

manufacturer, and motors are usually capable of operating both above 
and below the rated motor horsepower. As a result, the existing test 
procedure in subpart X of 10 CFR part 431 relies on the definition of 
small electric motor (e.g., a general purpose motor according to NEMA 
MG 1-1987), but the DOE regulations do not explicitly address how to 
determine the full-load or rated motor horsepower of a motor.
    To better specify the test procedures, DOE is considering 
approaches to determine rated motor horsepower based on motor 
properties like breakdown torque and temperature rise. NEMA Standards 
Publication MG 1-2014, (MG 1-2014), ``Motors and Generators,'' section 
10.34 specifies that the rated motor horsepower of a small or medium 
single-phase induction motor is based on breakdown torque. NEMA MG 1-
2014 then provides ranges of breakdown torque associated with rated 
motor horsepower and pole configurations. However, DOE identified 
multiple motor models that had a manufacturer-listed breakdown torque 
outside of the associated NEMA range (i.e., for a given topology, pole 
configuration, and rated motor horsepower), indicating not all motors 
follow the conventions listed in NEMA MG 1-2014.
    Another option would be to determine the rated motor horsepower 
based on a load which results in a temperature rise associated with the 
insulation class of the motor (i.e., service factor load). Insulation 
class is a letter designation (i.e., A, B, F, and H), which has an 
associated temperature rise indicating the temperature at which the 
motor can operate, and is commonly displayed in manufacturer literature 
and on motor nameplates. DOE is aware of insulation class temperature 
rises in NEMA MG 1-2014 section 12.42 and 12.43, and also in IEEE 112-
2004 Table 1 which may be applicable to this method. The load which 
results in the insulation class temperature rise would be a repeatable 
loading point, but DOE will consider if it is appropriate for 
determining efficiency, or if it could be indirectly used as a 
reference point for calculating the rated motor horsepower.
    Issue 22: DOE requests comment on how industry currently determines 
the full-load, or rated, horsepower of a motor, and how DOE should 
specify this quantity.
    Issue 23: DOE requests comment and input on a method to determine 
full-load, or rated, horsepower of a motor based on the breakdown 
torque of a motor as specified in NEMA MG 1-2014.
    Issue 24: DOE requests comment and input on a method to determine 
full-load, or rated, horsepower of a motor based on the load which 
results in a temperature rise associated with the insulation class of 
the motor (i.e., service factor load). DOE also requests comment on 
whether all motors have an associated NEMA insulation class (i.e., A, 
B, F, and H) that is known by the manufacturer, and if it is not known 
if there are methods a manufacturer can use to determine the insulation 
class. DOE also requests comment on the temperature rise that should be 
associated with each insulation class for this method (e.g., values 
from NEMA MG 1-2014 or IEEE 112-2004).
3. Represented Value
    The procedure for determining the represented value of average 
full-load efficiency of a small electric motor can be found at 10 CFR 
431.445. Specifically, DOE provides sampling provisions that must be 
used when determining the average full-load efficiency of a basic model 
through testing. On June 24, 2016, DOE published a separate notice of 
proposed rulemaking on certification, compliance, labeling, and 
enforcement for electric motors and small electric motors, which 
included a proposal to revise the sampling provisions for small 
electric motors to conform with the sampling provisions for other types 
of covered product and equipment at 10 CFR part 429, subpart B. 81 FR 
41378.
    DOE plans to investigate whether the proposed sampling provision 
for determining the represented value \11\ of a small electric motor 
could apply to the new motors DOE may consider regulating or whether 
the current sampling provisions need to be revised. DOE's preference is 
that all motors discussed in section II.A be subject to the same 
sampling provisions and represented value calculation.
---------------------------------------------------------------------------

    \11\ A represented value is a figure characterizing motor energy 
efficiency for the purposes of marketing or certifying performance 
to DOE.
---------------------------------------------------------------------------

    Issue 25: DOE requests comment on applying (1) the sampling plan in 
DOE's separate notice of proposed rulemaking (81 FR 41378, [June 24, 
2016]) and (2) the represented value calculation for small electric 
motors to new motors DOE may consider regulating.

D. Other Test Procedure Topics

    In addition to the issues identified earlier in this document, DOE 
welcomes comment on any other aspect of the existing test procedures 
for small electric motors not already addressed by the specific areas 
identified in this document. DOE particularly seeks information that 
would improve the repeatability, reproducibility, and consumer 
representativeness of the test procedures. DOE also requests 
information that would help DOE create a procedure that would limit 
manufacturer test burden through streamlining or simplifying testing 
requirements. Comments regarding repeatability and reproducibility are 
also welcome.
    DOE also requests feedback on any potential amendments to the 
existing test procedure that could be considered to address impacts on 
manufacturers, including small businesses. Regarding the Federal test 
method, DOE seeks comment on the degree to which the DOE test procedure 
should consider and be harmonized with the most recent relevant 
industry standards for small electric motors and whether there are any 
changes to the Federal test method that would provide additional 
benefits to the public.
    Additionally, DOE requests comment on whether the existing test 
procedures limit a manufacturer's ability to provide additional 
features to consumers of small electric motors. DOE particularly seeks 
information on how the test procedures could be amended to reduce the 
cost of these new or additional features and make it more likely that 
such features are included on small electric motors.
