In this paper, a novel dual-stator permanent magnet machine (DsPmSynM) with low cost and high torque density is designed. The winding part of the DsPmSynM adopts phase-group concentrated-coil windings, and the permanent magnets are arranged by spoke-type. Firstly, the winding structure reduces theamount of copper at the end of the winding. Secondly, the electromagnetic torque ripple of DsPmSynM is suppressed by reducing the cogging torque. Furthermore, the dynamic performance of DsPmSynM is studied. Finally, the experimental results are compared with the simulation results.

采用相群集中线圈绕组的辐条型双定子永磁电机的研究与设计

本文设计了一种低成本，高转矩密度的新型双定子永磁电机（DsPmSynM）。DsPmSynM的绕组部分采用相群集中线圈绕组，永磁体采用轮辐式排列。首先，绕组结构减少了绕组末端的铜量。其次，通过减小齿槽转矩来抑制DsPmSynM的电磁转矩波动。此外，研究了DsPmSynM的动态性能。最后，将实验结果与仿真结果进行比较。
