1   Scope and object

This part of IEC 60349 is applicable to rotating electrical machines, other than electronic converter-fed alternating current motors, forming part of the equipment of electrically propelled rail and road vehicles. The vehicles 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.
Where further testing is to be undertaken in accordance with IEC 61377‑2, it may be preferable, to avoid duplication, that some type and investigation tests be carried out on the combined test bed.

NOTE 1 This standard also applies to machines installed on trailers hauled by electrically propelled vehicles.

NOTE 2 The 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 features that may be required.

NOTE 3 It is not intended that this standard should apply to machines on small road vehicles such as battery-fed delivery vehicles, works trucks, etc. Neither does it 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 the IEC 60034 series may be suitable for certain auxiliary applications.

Electrical inputs or outputs of machines covered by this standard may be as follows:
  1. a) direct current (including rectified polyphase alternating current);
  2. b) pulsating current (rectified single-phase alternating current);
  3. c) unidirectional chopper-controlled current;
  4. d) single-phase alternating current;
  5. e) polyphase alternating current (in general three-phase).
In this standard, the electrical machines concerned are classified as follows.
  1. 1) Traction motors – Motors for propelling rail or road vehicles.
  2. 2) Engine-driven main generators – Generators for supplying power to traction motors on the same vehicle or train.
  3. 3) Main motor-generator sets – Machines obtaining power from a line or battery, and supplying power to traction motors on the same vehicle or train.
  4. 4) Auxiliary motors – Motors for driving compressors, fans, auxiliary generators or other auxiliary machines.
  5. 5) Auxiliary generators – Generators for supplying power for auxiliary services such as air conditioning, heating, lighting, battery charging, etc.
  6. 6) Auxiliary motor-generator sets and auxiliary rotary converters – Machines which obtain their power from the line or other source to provide an electrical supply for auxiliary services.
