§ 431.12 Definitions.
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 IEEE Std 112-2004 and CSA C390-10 (incorporated by reference, see § 431.15).
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.
(1) To standard ratings with standard operating characteristics or standard mechanical construction for use under service conditions other than usual, such as those specified in NEMA MG1-2009, paragraph 14.3, “Unusual Service Conditions,” (incorporated by reference, see § 431.15); or
Electric motor with encapsulated windings means an electric motor capable of passing the conformance test for water resistance described in NEMA MG 1-2009, paragraph 12.62 (incorporated by reference, see § 431.15).
Electric motor with moisture resistant windings means an electric motor that is capable of passing the conformance test for moisture resistance generally described in NEMA MG 1-2009, paragraph 12.63 (incorporated by reference, see § 431.15).
Electric motor with sealed windings means an electric motor capable of passing the conformance test for water resistance described in NEMA MG 1-2009, paragraph 12.62 (incorporated by reference, see § 431.15).
Fire pump electric motor means an electric motor, including any IEC-equivalent, that meets the requirements of section 9.5 of NFPA 20 (incorporated by reference, see § 431.15).
(1) Standard operating characteristics and mechanical construction for use under usual service conditions, such as those specified in NEMA MG1-2009, paragraph 14.2, “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 MG1-2009, paragraph 14.3, “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.
Note to Definition of General purpose electric motor (subtype I):
References to “MG1” above refer to NEMA Standards Publication MG1-2009 (incorporated by reference in § 431.15). References to “IEC” above refer to IEC 60034-1, 60034-12, 60050-411, and 60072-1 (incorporated by reference in § 431.15), as applicable.
(1) Is built in accordance with NEMA U-frame dimensions as described in NEMA MG1-1967 (incorporated by reference, see § 431.15) or in accordance with the IEC metric equivalents, including a frame size that is between two consecutive NEMA frame sizes or their IEC metric equivalents;
Note to Definition of General purpose electric motor (subtype II):
With the exception of the NEMA Motor Standards MG1-1967 (incorporated by reference in § 431.15), references to “MG1” above refer to the 2009 NEMA MG1-2009 (incorporated by reference in § 431.15). References to “IEC” above refer to IEC 60034-1, 60034-12, 60050-411, and 60072-1 (incorporated by reference in § 431.15), as applicable.
(1) Is designed to withstand full-voltage starting and developing locked-rotor torque as shown in NEMA MG 1-2009, paragraph 12.38.1 (incorporated by reference, see § 431.15);
(2) Develops locked-rotor, breakdown, and pull-up torques adequate for general application as specified in sections 12.38, 12.39 and 12.40 of NEMA MG1-2009 (incorporated by reference, see § 431.15);
(1) Is Designed to withstand full-voltage starting and developing locked-rotor torque for high-torque applications up to the values shown in NEMA MG1-2009, paragraph 12.38.2 (incorporated by reference, see § 431.15);
Nominal full-load efficiency means, with respect to an electric motor, a representative value of efficiency selected from the “nominal efficiency” column of Table 12-10, NEMA MG1-2009, (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.
