Abstract: The principle and characteristics of demagnetization of ferrite permanent magnet were briefly introduced. The demagnetization distribution characteristics of a 36 slot 6 pole ferrite permanent magnet assisted synchronous reluctance motor (PMSynRM) was analyzed by using a finite element method. According to its demagnetization characteristics, the improved structures such as unequal thickness permanent magnet, permanent magnet move toward the center of rotor, and permanent magnet slot trimming was proposed, and its improvement effect of demagnetization was verified by finite element simulation. The influence of each improved structure on the amount of permanent magnet, efficiency and demagnetization rate was compared, and the final scheme was determined. The simulation results show that the optimization of rotor structure can effectively improve the irreversible demagnetization of ferrite PMSynRM, and make it have more extensive applications and application prospects.

Key words: permanent magnet assisted synchronous reluctance motor(PMSynRM), ferrite permanent magnet, irreversible demagnetization, demagnetization current
