Pertains to converter-fed alternating current motors forming part of the equipment of electrically propelled rail and road vehicles.

1 Scope and object This part of IEC60349 applies to converter-fed alternating current motors forming part of the equipment of electrically propelled rail and road vehicles. The object of this part 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 in accordance with IEC61377-1 and IEC61377- 3, 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 converter as detailed in 5.1.NOTE1 This part also applies to motors installed on trailers hauled by powered vehicles.NOTE2 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.NOTE3 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.NOTE4 Industrial type motors complying with IEC60034 may be suitable for some auxiliary drives, providing that it is demonstrated that operation on a converter supply will meet the requirements of the particular application.The rating of traction motors fed in parallel by a common converter has to take into account the effect on load-sharing of differences of wheel diameter and of motor characteristics as well as 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. The electrical input to motors covered by this part comes from an electronic converter.NOTE5 At the time of drafting, 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 converters; asynchronous motors fed by current source converters; synchronous motors fed by current source converters.The motors covered by this part are classified as follows: Traction motors – Motors for propelling rail or road vehicles. Auxiliary motors not covered by IEC60034 – Motors for driving compressors, fans, auxiliary generators or other auxiliary machines.
