  • This paper presents a simulation method for studying the fault diagnosis of electric machines. The internal short circuit fault of pm machines is used as an example. A FE-based phase variable model is proposed to describe the pm machines with internal short circuit faults. The FE-based model is built using the solutions obtained from the FE modeling of the machine with the same fault. Such a model has two features. It includes the precise information of faults. Also, it allows a fast system simulation, which is desirable by diagnosing the fault of machines connected to a control circuit. Wavelet transform is used to perform machine current/voltage signature analysis. The obtained results show the practicality of the proposed diagnosis method. © 2006 IEEE.
