BS EN 60349-2:2001 Railway applications - Rotating electrical machines for rail and road vehicles - Electronic convertor-fed alternating current motors
1 This European Standard applies to convertor-fed alternating current motors forming part of the equipment of electrically propelled rail and road vehicles.
The object of this part 2 of EN 60349 is to enable the performance of a motor to be confirmed by tests and to provide a basis for assessment of its suitability for a specified duty and for comparison with other motors.
Where further testing is to be undertaken to EN 61377 "Combined testing of inverter-fed alternating current motors and their control", it may be preferable, to avoid duplication, that some type and investigation tests be carried out on the combined test bed.
Particular attention is drawn to the need for collaboration between the designers of the motor and its associated convertor as detailed in clause 3.1.
NOTE 1 This part also applies to motors installed on trailers hauled by powered vehicles.
NOTE 2 The basic requirements of this part may be applied to motors 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 motors 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 motors complying with EN 60034 may be suitable for some auxiliary drives, providing that it is demonstrated that operation on a convertor supply will meet the requirements of the particular application.
2 The rating of traction motors fed in parallel by a common convertor has to take account of the effect on load-sharing of differences of wheel diameter and of motor characteristics and also of weight transfer when operating at high coefficients of adhesion. The user is to be informed of the maximum permissible difference in wheel diameter for the particular application.
3 The electrical input to motors covered by this part has to be from an electronic convertor.
NOTE At the time of drafting this part only the following combinations of motors and converters had been used for traction applications, but it may also apply to other combinations which may be used in the future:
- asynchronous motors fed by voltage source convertors;
- asynchronous motors fed by current source convertors;
- synchronous motors fed by current source convertors.
The motors covered by this part are classified as follows:
- Traction motors
Motors for propelling rail or road vehicles.
- Auxiliary motors not covered by EN 60034
Motors for driving compressors, fans, auxiliary generators or other auxiliary machines.
