25、ss than 460 volts and all other rotating electrical machines and linear motors, both AC and DC, rated 1,000 volts or less. 1.2 This Standard is used to evaluate both motors intended to be eld installed as well as those intended to be factory installed. Motors intended to be factory installed need no

26、t comply with the requirements in Section 12, Ventilation Openings; Section 13, Accessibility of Uninsulated Live Parts, Film-Coated Wire, and Moving Parts; 16.9 16.16, 16.28, 18.1 18.5, 33.1 33.3, 33.5 33.7, and 34.1. 1.3 For the purposes of this Standard, the term “machine” is representative of an

27、d equivalent to the terms rotating electrical machine and rotating machine, and is understood to mean all manner of electric motors and generators covered by the scope of this Standard. The term “machine” is understood to apply to both AC and DC machines. 1.4 These requirements do not cover machines

28、 intended for use in hazardous locations as dened in the National Electrical Code, NFPA 70. The National Electrical Code and NEC are registered trademarks of the National Fire Protection Association, Inc., Quincy, MA 02169 1.5 These requirements do not cover sealed (hermetic type) motor-compressor p

29、arts, which are evaluated under the Standard for Hermetic Refrigerant Motor-Compressors, UL 984. 1.6 If the risk of re does not exist at a machine, part, or circuit, then the requirements of this Standard and associated parts of this Standard, intended to address the risk of re shall not apply to th

30、at machine, part, or circuit. 1.7 If the risk of electric shock does not exist at a machine, part, or circuit, then the requirements of this Standard and associated parts of this Standard, intended to address the risk of electric shock shall not apply to that machine, part, or circuit. 1.8 The requi

31、rements of this Standard and associated parts of this Standard, intended to address the risk of re do not apply to a motor provided with a metal enclosure in which there are no openings in the enclosure through which molten metal, burning insulation, aming particles, or other ignited material could

32、fall onto ammable material, or through which a ame could be projected.

36、d. 2.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain

37、temperatures not exceeding specied limits, and shall be used only under those specic conditions. 3 Units of Measurement 3.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 4 Undated References 4.1 Any undated reference to a cod
