431.12—Definitions.
The following definitions apply for purposes of this subpart, and of subparts K through M of this part. Any words or terms not defined in this Section or elsewhere in this Part shall be defined as provided in Section 340 of the Act.
Accreditation means recognition by an accreditation body that a laboratory is competent to test the efficiency of electric motors according to the scope and procedures given in Test Method B of Institute of Electrical and Electronics Engineers (IEEE) Standard 112-1996, Test Procedure for Polyphase Induction Motors and Generators, and Test Method (1) of CSA Standard C390-93, Energy Efficient Test Methods for Three-Phase Induction Motors. (Incorporated by reference, see § 431.15 )
Accreditation body means an organization or entity that conducts and administers an accreditation system and grants accreditation.
Accreditation system means a set of requirements to be fulfilled by a testing laboratory, as well as rules of procedure and management, that are used to accredit laboratories.
Accredited laboratory means a testing laboratory to which accreditation has been granted.
Alternative efficiency determination method or AEDM means, with respect to an electric motor, a method of calculating the total power loss and average full load efficiency.
Average full load efficiency means the arithmetic mean of the full load efficiencies of a population of electric motors of duplicate design, where the full load efficiency of each motor in the population is the ratio (expressed as a percentage) of the motor's useful power output to its total power input when the motor is operated at its full rated load, rated voltage, and rated frequency.
Basic model means, with respect to an electric motor, all units of a given type of electric motor (or class thereof) manufactured by a single manufacturer, and which have the same rating, have electrical characteristics that are essentially identical, and do not have any differing physical or functional characteristics which affect energy consumption or efficiency. For the purpose of this definition, “rating” means one of the 113 combinations of an electric motor's horsepower (or standard kilowatt equivalent), number of poles, and open or enclosed construction, with respect to which § 431.25 prescribes nominal full load efficiency standards.
Certificate of conformity means a document that is issued by a certification program, and that gives written assurance that an electric motor complies with the energy efficiency standard applicable to that motor, as specified in § 431.25.
Certification program means a certification system that determines conformity by electric motors with the energy efficiency standards prescribed by and pursuant to the Act.
Certification system means a system, that has its own rules of procedure and management, for giving written assurance that a product, process, or service conforms to a specific standard or other specified requirements, and that is operated by an entity independent of both the party seeking the written assurance and the party providing the product, process or service.
CSA means CSA International.
Definite purpose motor means any motor designed in standard ratings with standard operating characteristics or standard mechanical construction for use under service conditions other than usual, such as those specified in National Electrical Manufacturers Association (NEMA) Standards Publication MG1-1993 (MG1), Motors and Generators, paragraph 14.03, “Unusual Service Conditions,” (Incorporated by reference, see § 431.15) or for use on a particular type of application, and which cannot be used in most general purpose applications.
Enclosed motor means an electric motor so constructed as to prevent the free exchange of air between the inside and outside of the case but not sufficiently enclosed to be termed airtight.
Fire pump motors [Reserved]
General purpose motor means any motor which is designed in standard ratings with either:
(1)
Standard operating characteristics and standard mechanical construction for use under usual service conditions, such as those specified NEMA Standards Publication MG1-1993, paragraph 14.02, “Usual Service Conditions,” (Incorporated by reference, see § 431.15) and without restriction to a particular application or type of application; or
(2)
Standard operating characteristics or standard mechanical construction for use under unusual service conditions, such as those specified in NEMA Standards Publication MG1-1993, paragraph 14.03, “Unusual Service Conditions,” (Incorporated by reference, see § 431.15) or for a particular type of application, and which can be used in most general purpose applications.
General purpose electric motor (subtype I) means any motor which is designed in standard ratings with either:
(1)
Standard operating characteristics and standard mechanical construction for use under usual service conditions, such as those specified in NEMA Standards Publication MG1-1993, paragraph 14.02, “Usual Service Conditions,” (incorporated by reference; see § 431.15) and without restriction to a particular application or type of application; or
(2)
Standard operating characteristics or standard mechanical construction for use under unusual service conditions, such as those specified in NEMA Standards Publication MG1-1993, paragraph 14.03, “Unusual Service Conditions,” (incorporated by reference; see § 431.15) or for a particular type of application, and which can be used in most general purpose applications.
General purpose electric motor (subtype II) means any motor incorporating the design elements of a general purpose electric motor (subtype I) that are configured as one of the following:
IEC means the International Electrotechnical Commission.
IEEE means the Institute of Electrical and Electronics Engineers, Inc.
NEMA means the National Electrical Manufacturers Association.
Nominal full load efficiency means, with respect to an electric motor, a representative value of efficiency selected from Column A of Table 12-8, NEMA Standards Publication MG1-1993, (Incorporated by reference, see § 431.15 ), that is not greater than the average full load efficiency of a population of motors of the same design.
NEMA design B general purpose electric motor [Reserved]
Open motor means an electric motor having ventilating openings which permit passage of external cooling air over and around the windings of the machine.
Special purpose motor means any motor, other than a general purpose motor or definite purpose motor, which has special operating characteristics or special mechanical construction, or both, designed for a particular application.
Total power loss means that portion of the energy used by an electric motor not converted to rotational mechanical power, expressed in percent.
