Abstract :
This paper deals with faults in permanent magnet machines used in the traction chain of electrical and hybrid vehicles. First a state of the art is presented on the most encountered faults in these motors: that is permanent magnet demagnetisation, rotor eccentricity and short-circuits of stator windings. Then, an overview of electromagnetic and mechanical signatures of these faults is exposed through some simulation results about a permanent magnet synchronous motor. The developed models can be suitably used in diagnosis operations.
