Finite element method is a good tool to min. the cogging torque. There is many papers related to this issue.

cogging torque 主要是因轉子或定子上的slotting造成,而cogging torque 可以採用斜槽結構或環磁傾斜充磁的方式降低其ripple.

補充一下,基本上,斜槽結構或環磁傾斜充磁對ripple的抑制效果是差不多的,但斜槽結構電樞的線圈繞線較為困難些.

你可在"Brushless Permanent-Magnet Motor Design"這本書，作者Duane C. Hanselman，找到你想要的相關資料。在第34期電子報的每週一書可看到第二版的介紹

Skewing also has the effect of improving the stator windings distribution and substantially reduces higher order back-EMF harmonics.
