Developing of a method for complex diagnostics of traction electric motors

Traction electric motor (TEM) is the most important assembly of the electrical-driven rolling stock (EDRS). Out of a total number of EDRS failures only about 30% are TEM failures. If one of TEM fails, it causes higher loads for other motors and that shortens the motors' lifetime.

Today there are several problems in the TEM diagnostics:

• lack of the modern diagnostic systems in the depot and maintenance depot;
• lack of the system viewpoint: every system diagnoses certain parameters of TEM which are not in the common base of the specific TEM.

In the article the complex diagnostic method for traction electric motor is presented. The method will allow changing of the traction electric motor repair type from the operation-based repair into condition-based repair.
