摘　　要：针对目前同步磁阻电动机转矩脉动大、转矩密度与功率因数低等缺点,分析了同步磁阻电动机转子磁障占有率对电动机性能的影响,提出一种新的不均匀转子结构。使用Ansys软件搭建的有限元仿真模型进行仿真分析,在结构设计中结合C型磁障达到更好的转矩输出性能与效率表现,对转子磁桥的布置进行了机械应力的验证。仿真结果表明,同步磁阻电动机转子设计能有效降低转矩脉动,提高输出效率。Aiming at the shortcomings of synchronous reluctance motor such as large torque ripple,low torque density and low power factor,this paper takes 1.1 kW three-phase synchronous reluctance motor as an example to analyze the influence of synchronous motor rotor magnetic barrier occupancy rate on motor performance,and a new asymmetric rotor structure is proposed.Ansys is used to build a finite element simulation model for simulation verification,and the structure combined with the C-shaped magnetic barrier in the structural design is used to achieve better torque output performance and efficiency performance.Finally,two magnetic bridge arrangements are verified by mechanical stress simulation,and the results prove that the proposed synchronous reluctance motor design can effectively reduce torque ripple and improve the output efficiency.
