开关磁阻电机已用于电动汽车上,但运用在小功率的电动自行车上还不太多见。文中主要对比了两种结构方案,分别为三相36/24结构电机和18/24结构电机。提出的两种电机结构均为外转子,既配合轮毂电机的安装,又可以在有电机外径限制下增大气隙直径和电机出力。基于AnsoftMaxwell2D的有限元场路一体化分析,建立了电机性能仿真模型。在得出磁化曲线族的基础上,通过数值计算,计算和分析不同结构方案下SRM起动转矩、电机出力、效率以及过载能力,结果18/24综合性能更优,选择三相18/24结构SRM作为最终方案,并对其进行了结构优化。最后得出结论：通过仿真研究,18/24结构电机可以满足电动车的各种性能指标。

Switched reluctance motor has been used in electric cars,but used in low-power electric bicycle is not too much to see. Com-pare the two kinds of structures,three-phase 36/24 structure motor and 18/24 structure motor respectively. The two kinds of motor struc-tures are outer rotor,not only can fit hub motor installation,but also can increase air gap diameter and motor output under limited diame-ter. Based on Ansoft Maxwell2D finite element field analysis,establish the motor performance simulation model. Based on the magnetiza-tion curves,through the numerical calculation,calculate and analyze the starting torque,motor output,efficiency and overload capacity in the different structures,then choose three phase 18/24 SRM as a final project,and analyze the structure optimization. Conclusion is ob-tained that through the simulation,18/24 structure can satisfy all kinds of electric motor performance.
