Q:\CE-40\CE-43 \43COMMON\RABA\MOTOR03.MTG May 11, 1995SUPPLEMENTARY INFORMATION:

1. Authority.

Part .3 of Title IV of the National Energy lonservation Policy Act of 1978 (NECPA), Public Law 95-619, amends the Energy Policy and Conservation Act of 1975 (EPCA) to add "Energy Efficiency of Industrial Equipment," which includes electric motors. The most recent amendment to EPCA, the Energy Policy Act of 1992 (EPAct), Public Law 102-486, promulgates definitions related to electric motors in §122(a), 106 Stat. 2807, test procedures for motor efficiency in §122(b), 106 Stat. 2809, labeling for electric motors in §122(c), 106 Stat. 2809, standards for nominal full-load efficiency in §122(d), 106 Stat. 2814, and certification of compliance by manufacturers in §122(e), 106 Stat. 2817.

Section 122(a)(3) of the EPAct (EPCA, §340(13)(A), 42 U.S.C. §6311 (13)(A)), defines "electric motor" as any motor which is "general purpose T - frame, single -speed, foot- mounting ,- polyphase squirrel-cage induction of the National Electrical Manufacturers Association (NEMA) Designs A and B, 

### continuous-rated, operating on 230/460 volts and constant 60 Hertz line power, as defined in NEMA Standards Publication MG1-1987. " Section 122(d) of the EPAct (EPCA, §342(b)(1), 42 U.S.C. §6313(b)(1)), prescribes standards for electric motors that are 1 through 200 horsepower, and "manufactured (alone or as a component of another piece of equipment)," except for "definite purpose motors, special purpose motors, and those motors exempted by the Secretary."

- Q:\CE-40\CE-43\43COMMON \RABA\MOTOR03.MTG 3 May 11. 1995Section 122(b)(1) of the EPAct (EPCA, §343(a)(5)(A), 42 U.S.C. §6314

(a)(5)(A)), requires that testing procedures for motor efficiency shall be the test procedures specified in NEMA Standards Publication MG1-1987, and the Institute of Electrical and Electronics Engineers (IEEE ) Standard 112 Test Method B for motor efficiency, as in effect on October 24, 1992. Section 122(b)(1), EPCA §343( a)(5)(B) and ( C), provide for amendment of the testing procedures if the test procedures in the NEMA and IEEE standards are'revised.

Section 122(c)(4) of the EPAct (EPCA, §344(d), 42 U.S.C. §6315(d)) directs the Secretary, after- consultation with the Federal Trade Commission, see EPCA §344(f), 42'U.S.C. §6315(f), to prescribe rules
. requiring motor labeling .to indicate energy efficiency on the permanent nameplate , to display that motor- energy efficiency prominently in catalogs and other marketing materials , and to include other markings to facilitate enforcement of the 

### energy efficiency standards.

Section 122(e)(2) of the EPAct (EPCA, §345(c), 42 U.S.C. §6316(c)) requires manufacturers to certify compliance with energy efficiency standardsthrough an independent testing or certification program nationally recognized in the United States.

2. Background.

The Department of Energy is drafting a proposed rule to implement the EPAct requirements for motors. . However, the. language of the EPAct raises several issues regarding definitions , testing, , labeling, and certification.

Q:\CE-40 \CE-43\43COMMON \RABA\MOTOR03.MTG May 11, 1995The purpose of the public meeting is to discuss these issues, gather

information, and seek early resolution.

Discussion.



### The Department is interested in receiving information and statements to help resolve the following issues:

a. Definitions. 1) Metric Equivalents. Section 122(d) of the EPAct (EPCA,' §342(b)(1), 42 U.S.C. §6313(b)(1)) lists standards for electric motor nominal full-load efficiency ratings corresponding to horsepower and number of poles. Additionally, .§205b. of the Metric Conversion Act of 19.75, Public Law 94-168, 15 U.S.C. 205b., states "the declared policy of the United States- (1) to designate the metric system of measurement as the preferred system of weights and measures for United States trade and commerce; (2) to require that each Federal-agency, by 'a date certain and to the extent economically feasible by the end of the fiscal year 1992, use the metric system of measurement in its 

### procurementsr grants, and other business-related activities, except to the extent that such use is impractical or is likely to cause significant inefficiencies or loss of markets to United States firms, such as when foreign competitors are producing competing products in non-metric units." This policy is promulgated in Executive Order 12770 of July 25, 1991, "Metric Usage in Federal Government Programs." 56 FR 35801-03 (July 29, 1991). The Department seeks advice on how to implement these statutes with respect to motors under the EPAct. Specifically, should the energy efficiency_rules

Q:\CE-40\CE-43\43COMMON\RABA\MOTOR03.MTG 5 - May 11, 1995identify,kilowatt ratings equivalent to corresponding horsepower ratings, and

other electrical and mechanical equivalents? If so how?

2) Basic Model. The Code of Federal Regulations (CFR ), in 10 CFR Part 430 §430.2, provides a definition for the term " basic model " in regard to the appliance program : " Basic model means all un its of a given type of covered product ( or class thereof ) manufactured by one manufacturer and-- ...[as to dishwashers , for example ] which have electrical characteristics that are essentially identical , and which do not'have any differing physical or functional characteristics that affect energy consumption ." Basic model is a term used to describe a product or item of equipment whose performance, design, mechanical , and functional characteristics are essentially the same. Components of similar design may be substituted in a basic model without requiring additional testing if the represented measures of energy consumption continue to satisfy applicable provisions for sampling and testing. In the case of electric motors , a manufacturer may produce one basic model and thousands more of other model numbers that are essentially the same, all based on variations in design features that do not affect energy efficiency.



### The Department is considering defining the term " basic model" in its coverage of electric motors to
. mean all units of a given type of covered equipment . ( or class thereof ) manufactured by a single manufacturer , and, with respect to electric motors , having the'same rating , electrical design characteristics that are essentially identical , and no differing mechanical or functional characteristics that affect energy consumption or efficiency. The

Q:\CE-40\CE,- 43\43COMMON\RABA\MOTOR03.MT6 6 - May 11, 1995Department solicits the views of interested parties as to whether the

Department should adopt such a definition.

3) Definite Purpose Motor. Under Section 122(d) of the EPAct (EPCA §342(b)(1), 42 U.S.C. §6313(b)(1)), the energy efficiency standards for electric motors do not apply to "definite purpose motors." Section 122(a)(3) of the EPAct (EPCA §340(13)(B), 42 U.S.C. §6311(13)(B)) defines a "definite purpose motor". as "any motor designed in standard ratings with standard operating characteristics or standard mechanical construction for use under service conditions other than usual, or for use on a particular type of application which cannot be used in most general purpose applications." However, the EPAct does not define the term "service conditions other than usual. " Therefore, the Department is considering developing a definition for this term that will take into consideration adverse environmental and operating conditions, such as exposure to abrasive or combustible dusts, chemical fumes, nuclear radiation, salt-laden air, abnormal shock or vibration, unbalanced supply voltage, power system not grounded, frequent starting, frequent short circuits , and so forth. The Department seeks advice in. developing a definition for "service conditions other than usual."

b. Testing.



### 1) Canadian Standards Association Standard C390. Section 122(b)(1) of the EPAct (EPCA, §343(a)(5)(A), 42 U.S.C. §6314(a)(5)(A)) states that "the test procedures shall be the test procedures specified in NEMA Standards Publication MG1-1987 and IEEE Standard 112 Test Method B for motor

Q:\CE-40 \CE-43 \43COMMON\RABA\MOTOR03.MTG, 7 May 11. 1995efficiency, as in effect on the date of the enactment of the Energy Policy Act

of 1992. " Subsequently, the NEMA Standards Publication MG1-1987 was revised and superseded by MG1-1993 on November 19, 1992, and published in October-19,93 

### as MG1-1993. A further amendment, Revision 1 to MG1-1993, was added on December 7, 1993.

The EPAct ( 42 U.S.C. §§6314(a)(5)(B) and ( C)) provides for amending the established test procedures if the -test ,procedures in NEMA Standards Publication MG1-1987 and IEEE Standard 112 Test Method B are amended. MG1-1993 with Revision 1, section MG1-12.58 .1 states: "Efficiency 

### and losses shall be determined in accordance with IEEE Std 112 or Canadian Standards Association Standard C390. " In considering whether to amend the motor efficiency test procedures specified in NEMA Standards'Publication MG1- 1987 in order to require the motor efficiency test procedures specified in NEMA Standards Publication MG1-1993 with Revision 1, the Department hereby solicits information on the affect of the additional reference to Canadian 

### Standards Association Standard C390.

2) Testing Sampling Plan. Section 122(d) of the EPAct (EPCA, §342(b), 42 U.S.C. §6313(b)) requires each electric motor to have a certain "nominal full load efficiency," which is defined in §122(a)(3) of the EPAct (EPCA §340(13)(H), 42 U.S.C. 6311(13)(H)) as the average efficiency of a population of motors of duplicate design as determined in accordance with NEMA Standards Publication MG1-1987. NEMA Standards Publications MG1-1987 and MGi 1993 with Revision .1 both provide for the determination of.nominal.full load 

### efficiencies that are to represent the average efficiency *of a large

8 - Q:\CE-40\CE-43\43COMMON\ RABA\MOTOR03.MTG May 11, 1995population of motors of duplicate design, and a corresponding minimum

efficiency that any motor must equal or exceed to be rated at the corresponding nominal efficiency. The DOE contemplates establishing a testing sampling plan to reasonably ensure that the results from testing a few motors will establish the average efficiency of the large population of motors of duplicate design. This could be done by requiring the testing of a sufficient number of motors of f a,parti`cular model, selected at random, so that an 

### estimate at the 95 percent statistical confidence level can be made both that the motors of this model offered for sale have both a mean efficiency equal to or greater than the nominal efficiency given in NEMA Standards Publication MG1-1993 Revision 1 for this rating, and also that at least 99 percent of these motors of this same particular model have efficiencies equal to or greater than the minimum efficiency associated with the nominal efficiency given for this motor in'the NEMA Standards Publication MG1-1993 Revision 1. The Department seeks advice on what type of sampling plan should be adopted.

3) Alternative Method of Efficiency Determination. In the case where a manufacturer produces hundreds of different basic models of electric. motors, it may be neither technically feasible, nor economically justifiable to test all basic models for compliance. For such situations, the Department is considering the use of predictive mathematical calculations and statistical, methodologies developed from scientific and engineering analyses that are substantiated by actual test data in order to calculate the efficiency, i.e. total power losses, for-some basic models of electric motors. Such "alternative efficiency determination methods," engineering or statistical analyses, would require support by actual testing of some minimum number of

Q:\CE-40\CE-43\43C O 'iON\RABA\MOTOR03.MTG May 11, 1995basic models and would.incorporate computer simulations, modeling, or other

mathematical evaluations of performance data. The alternate efficiency 

### determination method to verify compliance for motors is similar to the method used in the appliance program, 10 CFR Part 430, §430.24(m)(2)(.ii), that 

### permits manufacturers of central air conditioners to verify compliance by use of an "alternative rating method."

The Department solicits views on both the feasibility of testing all models of motors, as well as appropriate alternative methods for determining efficiency in the event it is not feasible to test all models.

c. . Labeling. Section 122(c)(4) of the EPAct (EPCA , §344(d), 42 U.S.C. §6315(d)) -requires the following: (1) "not later than 12 months after the Secretary establishes test procedures for electric motors-...the Secretary shall prescribe labeling rules.. .taking into consideration NEMA Standards Publication MG1-1987;" and (2) such labeling rules shall "(1) indicate the energy efficiency of the motor on the permanent nameplate attached to such motor; (2) prominently display the energy efficiency of the motor in equipment 

### catalogs and-other material used to. market the equipment; and (3) include such other markings as the Secretary determines necessary, solely to facilitate enforcement of the standards."

Based upon these EPAct requirements, the Department 'is considering the required use of a distinct logo, such as lower case letters."ee"-within a circle,-to identify motors that are manufactured as energy-efficient and in compliance with the EPAct. Such a logo would be permanently marked on the

10 - Q:\CE-40\CE-43\43COhMON \RA9A\MOTOR03.MTG May 11, 1995motor nameplate to facilitate'enforcement, be prominently displayed on

packaging , in shipping documents, in customs and commercial documents, and other materials. The Department is also considering a requirement of permanent markings on the motor nameplate of both the nominal efficiency and the minimum efficiency associated with that nominal efficiency, and of - prominent displays of both the nominal and minimum efficiency values in catalogs to assist purchasers in making purchasing decisions.

In addition, §122(c)(4) of the EPAct (EPCA, §344(c), 42 U.S.C. §6315(c)) authorized additional required displays of.information about electric motorenergy efficiency that are likely to assist purchasers in making purchasing decisions, including instructions for maintenance, use,. or repair of the motor, and information on energy use. Thus, the Department is also considering use of a label(s) or marking(s) that bear(s)'the following statement(s): (1) "This motor complies with energy efficiency requirements in' the Energy Policy Act of 1992 at the time of original manufacture, [DATE]."_or "Efficiency complies with,EPACT at time of. manufacture, [DATE]."; (2) "Consult the manufacturer for maintenance, use, or repair." or "Repair only in factory authorized-shop."; and (3) "Estimated kilowatts used after 2000 hours' continuous operation according to manufacturer's ratings: or "Est. annual kW used: ". (Annual would be defined as ".2000 hours continuous., operation according to manufacturer's ratings.") -



### The Department seeks advice on whether such label(s) or marking(s) would assist purchasers, and on the content, design, size, location, and attachment of such label(s) or marking(s).

0:\CE-40\CE-43\43C"ON\ RABA\MOTOR03.MTG - 1 1 - May 11 , 1995d. Certification. Section 122(e)(2) of the EPAct (EPCA §345(c), .42 U.S.C.

§6316(c)) requires "manufacturers to certify, through an independent testing or certification program nationally recognized in the United States, that such motor meets the applicable [nominal full=load efficiency standard]."

1) Compliance. The Department is considering implementation of the EPAct requirement for "manufacturers to certify" by means of a compliance statement and certification report that each basic model of energy efficient electric motor meets the requirements of the EPAct. This is similar to 10 C.F.R. Section 430.62(a), which sets forth the appliance program procedures to .be followed for certification by requiring each manufacturer to "certify by mean's of a compliance statement and certification report that each basic model 

### meets the requirements of that standard." A manufacturer's compliance statement and certification report for each basic model of energy efficient electric motor would be based, at least in part, upon actual testing or an alternative efficiency determination method. The Department solicits the views of interested parties on such a requirement.

2) Independent Testing and Certification. The Department. is also considering how to interpret and implement the EPAct requirement for "manufacturers-to certify, through an independent testing or certification program nationally recognized in the United States, that such motor meets the applicable [nominal full-load efficiency standard]." Such testing or certification programs could be operated by commercial laboratories, government laboratories, and trade associations. The Department seeks information as to the identity, nature, and capabilities of any nationally

Q:\CE-40\CE-43\43COMN1ON\RABA\ MOTORO3.MTG - 12 - May 11. 1995recognized program(s) for the testing and certification of motors. The

Department is aware that the Association of Home Appliance Manufacturers conducts a program to verify manufacturers' certifications of.the total. refrigerated volume of refrigerators and the energy efficiency values of room air conditioners; that the Gas Appliance Manufacturers As-sociation conducts a testing program to verify manufacturers' certifications of the energy efficiency of water heaters, furnaces, room heaters, and boilers; and that the Air Conditioning and Refrigeration Institute conducts a testing program to verify manufacturers' certifications of the energy efficiency and other, performance criteria of residential and commercial air conditioning and heat pump systems. The Department seeks information on any similar existing programs that certify or verify the performance characteristics. of motors. In addition, the Department seeks information as-towhether foreign commercial laboratories, foreign government laboratories, or trade associations operate such programs.

The Department also seeks advice concerning two other possible issues under §122(e) of the EPAct (EPCA §345(c), 42 U.S.C. §6316(c)). First, questions may arise as to what constitutes "an independent testing or certification program [that is] nationally recognized." The Department seeks input as to the criteria by which an -organization should be considered competent (1) to conduct the specific tests or calibrations for motors according to the required test procedures, and (2) to operate a certification program. One possibility is that th-e.Department could consider a motor testing or certification program to be "nationally recognized" if the program 

### were accredited by the National Institute of Standards and Technology/National

Q:\CE-40\CE-43 \43COMMON \RABA\MOTOR03.MTG - May 11. 1995 13Voluntary Laboratory Accreditation Program (NIST/NVLAP). The Department seeks

views on such an approach, including the question of whether a foreign program recognized by NIST/NVLAP should be considered "nationally recognized in the United States." Second, the Department seeks views as to whether manufacturers are permitted to self-test or self-certify the energy efficiency of their own motors, and, if so, under what circumstances.

e. Identification of Other Issues. The Department will seek to resolve the above issues in developing a proposed rule. In addition, there may be other issues that the Department will need to address. The purpose of the meeting is to identify all of these various 'issues and to begin dialogue with 

### interested parties to help resolve them.
