摘　　要：在不同奇数相下从转矩和转矩脉动两方面对方波励磁无刷电机的性能进行了比较,得出了励磁极的极弧度与电机转矩和转矩脉动的关系,和方波励磁无刷电机的电磁转矩脉动为最小的条件,为电机相数的选择提供了依据。Through comparison of the performance of square wave excitation blushless motor in consideration of the torque and torque pulsation at different odd phases, we obtain the relationships of poles arc angle to torque and torque pulsation, and the conditions of electromagnetic torque pulsation of square wave excitation blushless motor being minimum. These provide the reference for selection of number of motor phase.
