This paper introduces major potential faults of IPMSM and their simulation realization methods. 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 in 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.

가설 설정
In fig. 2 (b), the current of fault phase gets dominantly positive after 0.7s, and the polarities of other two phase current are negative. This accords with the wye connection of 3-phase windings, and the sum of phase currents always is zero.

For a given motor, the different load, fault time and PWM method may produce very different results. Therefore, this paper focuses on the fault analysis and simulation method. First, according to each phase and switch states, the circuits are analyzed as different fault case.
This paper introduces the potential faults and corresponding dynamic simulation for IPMSM which is used in HEV traction system. Due to the large power, high torque and high speed, the IPMSM used for HEV traction has more risks if some fault happen in controller, inverter or inside of motor.
대상 데이터
The motor analyzed in this paper is a 12KW soft-type IPMSM which is used in a parallel-type Hybrid Electric Vehicle traction system. The faultless 3-phase IPMSM generally is expressed as dq-equivalent model, the corresponding state-space equation is, where we is the electrical angular velocity of rotor, R, Ld, Lq, em stand for
