Abstract：The pole arc range of permanent magnet directly affects the rated and cogging torque of permanent magnet synchronous motor (PMSM),then further affects the output efficiency of motor energy.In this paper,a 0.75 kW,10 pole 12 slot surface mount permanent magnet synchronous motor was researched.By changing the polar parameters of permanent magnet pole (0.5 ～ 1),using ANSOFT and ANSYS simulation software,the rated torque,cogging torque were simulated.The optimum parameters of pole arc were summarized and analyzed so as to reduce cogging torque and improve the efficiency.
