• Electric traction - Rotating electrical machines for rail and road vehicles - Part 2: Electronic converter-fed alternating current motors

  Käsitlusala:

  This part of IEC 60349 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 IEC 61377-1 and IEC 61377-3, 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. 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. The motors covered by this part are classified as follows: a) Traction motors - Motors for propelling rail or road vehicles. b) Auxiliary motors not covered by IEC 60034 - Motors for driving compressors, fans, auxiliary generators or other auxiliary machines.
