19、onal foreword This Part of BS 173 has been prepared under the direction of the Power Electrical Engineering Standards Policy Committee. It is identical with IEC 349:1991 “Electric traction. Rotating electrical machines for rail and road vehicles” published by the International Electrotechnical Commi
20、ssion (IEC) and replaces BS 173:1980 which is withdrawn. There is a high probability that BS 173-2 “Specification for electronic convertor-fed alternating current motors” when published will be identical with IEC 349-2. Simultaneously, the title of this Part of BS 173 will be amended to “Part 1. Spe
21、cification for rotating electrical machines other than convertor-fed alternating current motors” and the text will be amended to delete tests which are applicable to convertor-fed motors. Appendix B of BS 173:1980 which was identical to IEC 850 is now published as BS 7571. BS 173:1980 implemented CE
22、NELEC HD 225, but there is a high probability that at a future date EN 60349 when published will be identical with IEC 349. At that time, this standard will be renumbered as BS EN 60349.

General 1.1 Scope and object 1.1.1 This International Standard is applicable to rotating electrical machines forming part of the equipment of electrically propelled rail and road vehicles. The vehicle
30、s may obtain power either from an external supply or from an internal source. The object of this standard is to enable the performance of a machine to be confirmed by tests and to provide a basis for assessment of its suitability for a specified duty and for comparison with other machines. NOTE 1Thi
31、s standard also applies to machines installed on trailers hauled by electrically propelled vehicles. NOTE 2The basic requirements of this standard may be applied to rotating electrical machines for special purpose vehicles such as mine locomotives, but it does not cover flameproof or other special f
32、eatures that may be required. NOTE 3It is not intended that this standard should apply to machines on small road vehicles such as battery-fed delivery vehicles, works trucks, etc. It does not apply either to minor machines such as windscreen wiper motors, etc. that may be used on all types of vehicl
33、es. NOTE 4Industrial type machines complying with IEC 34 may be suitable for certain auxiliary applications. 1.1.2 Electrical inputs or outputs of machines covered by this standard may be as follows: a) direct current (including rectified polyphase alternating current); b) pulsating current (rectifi
34、ed single-phase alternating current); c) unidirectional chopper-controlled current; d) single-phase alternating current; e) polyphase alternating current (in general three-phase). All the above may be synthesized and/or varied by phase or pulse control. 1.1.3 For the purpose of this standard, the el
35、ectrical machines concerned are classified as follows: 1.1.3.1 Traction motors Motors for propelling rail or road vehicles. 1.1.3.2 Engine-driven main generators Generators for supplying power to traction motors on the same vehicle or train. 1.1.3.3 Main motor-generator sets Machines obtaining power
36、 from a line or battery, and supplying power to traction motors on the same vehicle or train. 1.1.3.4 Auxiliary motors Motors for driving compressors, fans, auxiliary generators or other auxiliary machines. 1.1.3.5 Auxiliary generators Generators for supplying power for auxiliary services such as ai
37、r conditioning, heating, lighting, battery charging, etc. 1.1.3.6 Auxiliary motor-generator sets and auxiliary rotary convertors Machines which obtain their power from the line or other source to provide an electrical supply for auxiliary services. 1.2 Normative references The following standards co
38、ntain provisions which, through reference in this text, constitute provisions of this International Standard.
