摘　　要：根据实际工程问题需要设计一台极槽数相近配合的低速永磁同步电动机。利用有限元法对电机磁场进行分析,并通过时步有限元法对其性能进行了仿真。分析与仿真结果表明:尽管电机的气隙磁场远非正弦分布,但绕组的感应电动势很接近正弦,电磁转矩的脉动以及齿槽转矩较小。This paper introduces a low speed PM synchronous motor with approximate number of poles and slots which is designed for actual use. The magnet field is analyzed by finite element method and the performances are simulated by time-stepping finite element method. All the results show that the induction EMF is approximate to the sine wave, the pulsation of the electrical magnetic torque and the cogging torque are both small, although the air - gap magnetic field is far from sinusoidal.
