摘要：
The partial demagnetization of surface-mounted permanent magnets of PMSM in the three phase symmetrical short circuit of different temperature is analyzed by the finite element method. Then, rules of the back EMF and flux change in different extent of demagnetization are summarized. Finally, the operation behaviors and secondary demagnetization of the demagnetized PMSM are analyzed. Conclusion, which can judge and prevent demagnetization fault, is presented.
