Combining Schwarz–Christoffel transformation, magnetic field reconstruction method, and Maxwell stress tensor method, the calculation model of cogging torque of a dual‐stator axial flux permanent magnet machine is established. The end effect and slotting effect are both been taken into account. The results are verified by finite element method. And with the proposed method, calculation time can be significantly reduced compared with finite element method. Three measures to reduce the cogging torque of dual‐stator axial flux permanent magnet machines are discussed based on which the cogging torque is optimized by genetic algorithm. © 2020 Institute of Electrical Engineers of Japan.

双定子轴向磁通永磁电机的齿槽转矩计算与优化

结合Schwarz-Christoffel变换，磁场重建方法和Maxwell应力张量方法，建立了双定子轴向磁通永磁电机齿槽转矩的计算模型。都考虑了末端效应和开槽效应。结果通过有限元方法验证。并且，与有限元方法相比，该方法可以显着减少计算时间。讨论了降低双定子轴向磁通永磁电机齿槽转矩的三种措施，并通过遗传算法对齿槽转矩进行了优化。©2020日本电气工程师学会。由Wiley Periodicals LLC发布。
