基于12槽/10极磁通切换永磁电机(FSPMM)提出了定子切边齿、转子U型槽齿、转子凸缘齿3种新型齿形,以有效减小FSPMM电机的齿槽转矩和转矩波动。通过2D有限元法从平均转矩、齿槽转矩、转矩波动等方面对不同新型齿形的FSPMM的性能进行了全面的分析和评估。结果验证了所提出的3种新型齿形状,特别是转子U型槽齿和凸缘齿可以减小齿槽转矩和转矩波动,平均转矩只有轻微的减小。

Trimming teeth, Ushaped teeth and flange teeth based on 12slot/10pole flux switching permanent magnet motor (FSPMM) was proposed to reduce effectively cogging torque and torque ripple. The 2D finite element method analyzed and evaluated torque characteristics of different novel teeth from average electromagnetic torque, cogging torque, torque ripple. The results verify that the proposed three novel tooth shapes, especially rotor with Ushaped teeth and rotor with flange teeth, could effectively reduce cogging torque and torque ripple at only slight reduce in the average electromagnetic torque.
