提出了一种结构反凸极永磁同步电动机,利用有限元软件Ansys/Maxwell对反凸极永磁同步电动机进行仿真分析,完成了一台550 W样机的制作和实验。研究表明,所设计的反凸极永磁同步电动机稳态运行时转速波动及转矩脉动都要小于常规凸极永磁同步电动机,并且电动机损耗更小和效率也更优异,证明了该新型结构电动机的适用性和优越性。

Aiming at the problems existing in conventional salient permanent magnet synchronous motors, this paper proposes a novel structure negative-saliency permanent magnet synchronous motor, and uses the finite element software Ansys/Maxwell to simulate and analyze the novel structure negative-salient permanent magnet synchronous motor, and completes the production and experiment of a 550 W prototype. The research shows that the designed negative-saliency permanent magnet synchronous motor has a lower speed fluctuation and torque ripple at steady state than the conventional salient permanent magnet synchronous motor, and the performance of the motor loss and efficiency is also superior, which proves the proposed the correctness and superiority of the novel structure motor.
