摘　　要：针对某新型电动汽车用轮毂电机性能要求一种宽范围的调速特性,比较分析异步电机、开关磁阻电机、永磁同步电机和一种使用U型电磁铁的模块化横向磁场电机的调速方法与机械特性,分别进行电机模型设计。采用有限元仿真软件Ansoft对4种电机模型的机械特性、电磁损耗、效率和电磁重量等特性进行仿真,比较分析仿真结果进而提出最优电机设计模型。研究表明,相对于传统电机,基于U型电磁铁的模块化横向磁场电机的机械特性与设计要求配合最好;电磁重量最轻、功率密度最高;在500~6 000 r/min转速范围内,可实现85%~90%的稳定效率;模块化结构使设计方案更为简单,理论上具有较好的容错特性,是一种适用于电动汽车的新型轮毂电机。A kind of wide speed regulation characteristic motor was required by a new kind of electrical vehicle. To fulfil the requirement, this paper analyzed and compared the method of speed regulation and mechanical properties of induction motor （IM）, switched reluctance motor （SRM）, permanent magnet synchronous motor （PMSM） and a new kind of modularization transverse flux motor （MTFM） that used U-shaped electromagnets as its stators. Then, the design of these four motors was performed. Using the FEM software Ansoft to complete the simulation of the mechanical properties, electromagnetic loss, efficiency and net weight of the four designed motors. And the best motor was choose based on the comparison of the simula- tion results. The results show that the MTFM suits the requirement best. It is the one which has the lightest weight and the highest power density in these motors. The efficiency of this motor could maintain 85 - 90% while the speed varied from 500 r/min to 6 000 r/min. And the modularization structure makes the design of this motor becomes very simple. Theoretically, it also has relative good fauh tolerance ability. So, this MTFM is a new kind of motor which suits electrical vehicle well.
