Diagnostics of electric-driven rolling stock traction motors. Methods, types and main faults

Print

Statistical data about the traction motors failures, constituting more than 20% of the service failures total number, demonstrate the repair quality and motors testing at the repair enterprises. Thus, 65% of the motor failures occur for reasons of an electrical nature, such as: electrical breakdowns and turn-to-turn fault of armature winding, the main and additional poles, compensating windings. That testifies availability of factors, adversely affecting the dielectric resistance of the windings insulation. The suggestions for significant simplification of the traction electric motor testing process after repair, especially in the current repair № 3 process, are wrong.

Long-term experience in traction electric motors testing shows, that every month during the testing the 10-15 % of traction electric motors are identified with significant deviations in after-repair switching conditions at the Zheldorremmash plants.

On the assumption of the above-mentioned problems we suggest to tighten the control of testing and diagnostics of traction electric motors and fully automate the diagnostic complexes.
