Abstract :
The method to optimize the design of Permanent Magnet Synchronous Motor (PMSM) to solve irreversible permanent magnet demagnetization is discussed in this paper. A PMSM with rated speed 9000r/min and rated power 200 kW is used as origin model. The models except original one in this paper are designed by changing structure and parameters. The design of PMSM with lower eddy current loss of permanent magnet will be given by simulation and comparison of different models.
