Faults Analysis and Dynamic Simulation for Hybrid Electric Vehicle Traction Interior PM Synchronous Motor

This paper introduces major potential faults of IPMSM which is used in HEY traction system, and their simulation realization method based on Simulink@MATLAB. The faults of IPMSM, generally, contain single-phase open circuit, single-phase or 3-phase short circuit, and uncontrolled generation. When different fault occurs, the circuit of total system including motor and inverter also will be changed. Therefore, it is necessary to analyze and establish independent model for each kind of fault. In this paper, first, the drive circuit is analyzed as different fault type. Then, the corresponding simulation results solved by Simulink@MATLAB are given. The absence of experiment results leads that the veracity of simulation results can not be verified, but the tendency will be explained by theory analysis.
