16、 Corrosion; Factory Wiring Terminals and Leads; Spacings (when rated 1,000 V or less); and Current-Carrying Parts. For these Sections, the requirements of UL 1004-1 apply unless modied by this Standard. 1.2 For the purposes of this Standard, the term machine is representative of and equivalent to th

17、e 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. 1.3 These requirements apply to eld-installed machines with form

18、 wound windings and rated for applications between 460 V and up to 34,000 V. 1.4 This standard also applies to eld-installed machines employing random wound windings and rated for applications above 1,000 V and up to 7,200 V. 1.5 Machines intended for use in hazardous locations as dened in the Natio

19、nal Electrical Code, NFPA 70, may have additional requirements to be met as specied in the National Electrical Code, NFPA 70. 1.6 These requirements do not cover sealed (hermetic type) motor-compressor parts, which are evaluated under the Standard for Hermetic Refrigerant Motor-Compressors, UL 984.

20、1.7 These requirements do not cover special generators (such as hydrogen cooled (turbo) generators) rated 10 MVA and above which are covered under IEEE C50.12, IEEE Standard for Salient-Pole 50 Hz and 60 Hz Synchronous Generators and Generator/Motors for Hydraulic Turbine Applications Rated 5 MVA an

25、 hard, inert material. Cycloaliphatic epoxies (where “cycloaliphatic” is used as the curing agent) are noted for higher resistance to moisture and UV breakdown compared with non-cycloaliphatic epoxies. 5.3 FORM WOUND MACHINE A rotating electrical machine using insulated rectangular shaped conductors

26、 that are wrapped with additional electrical insulation over the entire coil prior to insertion and are precisely positioned and formed into coils. 5.4 RANDOM WOUND MOTOR A motor using insulated round magnet wire conductors in which the winding turns occupy random positions in a slot. 5.5 RTD/ETD Re
