Electric traction—Rotating electrical machines for rail and road vehicles—Part 4:Permanent magnet synchronous electrical machines connected to an electronic converter
This part of GB/T 25123 is applicable to permanent magnet synchronous electrical machines (motor or generator) connected to electronic converter and used for rail and road vehicles, which includes the following four types of machines:
Traction motor: motors for propelling rail or road vehicles;
Main generator: generators for supplying power to the traction motor on rolling stock;
Auxiliary motor: motors for driving compressors, fans, auxiliary generators or other auxiliary machines, which are not covered by GB 755;
Auxiliary generator: generators for supplying power for ancillary services such as air conditioning, heating, lighting and battery charging, etc., which are not covered by GB 755.
This part enables the performance of a machine to be confirmed by tests and provides a basis for assessment of its suitability for a specified duty and for comparison with other machines.
Note 1 This part also applies to machines installed on trailers hauled by powered vehicles.
Note 2 The basic requirements of this part may be applied to machines for special purpose vehicles such as mine locomotives but this part does not cover flameproof or other special features that may be required.
Note 3 It is not intended that this part should apply to machines on small road vehicles, such as battery-fed delivery vehicles, factory trucks, etc. This part also does not apply to minor machines such as windscreen wiper motors, etc. that may be used on all types of vehicles.
Note 4 Industrial type machines complying with GB 755 may be suitable for some auxiliary drives, provided that it is demonstrated that operation on a converter supply will meet the requirements of the particular application.
The electrical input to motors covered by this part is from an electronic converter. Generators may be connected to a rectifier or a converter.
