Abstract

An axial field switched flux permanent magnet (AFSFPM) machine possesses desirable advantageous performance since it combines the merits of both axial field permanent magnet (AFPM) and switched flux permanent magnet machines (SFPM). In this study, an axial field partitioned stator switched flux permanent magnet (AFPS-SFPM) machine has been individually optimized for maximum torque. Also, the influence of the slot shape on the machine performance has been investigated. It is found that higher torque can be obtained with parallel slot opening compared to radial slot opening. Furthermore, the effect of rotor iron piece shapes on the machine cogging torque is examined. It is shown that the machine torque ripple can be significantly reduced when the rotor iron piece edges are changed to be rounded border instead of flat shape. Moreover, a comparison between the initial and optimized machines has been carried out. It is concluded that the optimized machine has higher torque with less torque ripple compared to the initial machine.

轴向分磁场定子开关磁通永磁电机参数化设计优化

轴向磁场开关磁通永磁(AFSFPM)电机结合了轴向磁场永磁(AFPM)和开关磁通永磁(SFPM)的优点，具有理想的优越性能。在本研究中，对轴向分磁场定子开关磁通永磁(AFPS-SFPM)电机进行了最大转矩的单独优化。研究了槽形对机床性能的影响。发现平行开槽比径向开槽能获得更大的转矩。进一步研究了转子铁片形状对机床齿槽转矩的影响。结果表明，将转子铁片边缘改为圆边，可显著减小电机转矩脉动。此外，还对初始机和优化机进行了比较。结果表明，与初始电机相比，优化后的电机具有更高的转矩和更小的转矩脉动。
