摘　　要：针对高速运转时开关磁阻轮毂电机的转矩波动问题,基于ANSOFT MAXWELL 2D仿真平台,以3相12/8极外转子开关磁阻电机为例,进行静态和瞬态仿真分析,得到电机的各类特性曲线。参考这些特性曲线,可以在电机高速运行时,通过优化开通角、关断角和定子磁极结构来减少输出转矩波动——这些优化可使开关磁阻轮毂电机的输出转矩更为平顺。A switched reluctance motor based on simulation platform of ANSOFT MAXWELL 2D was introduced for problem of torque ripple of switch reluctance hub motor with external rotor in high speed operation. By static and transient simulation analysis, a three-phase 12/8 switched reluctance motor was analyzed as the prototype machine to obtain motor＇ all kinds of characteristic curves. When motor working in high speed, it could recede torque ripple by optimized turn-on angle, turn-off angle and magnetic pole structure of stator, with referring to these features. These optimization could provide a more smooth output torque of switched reluctance hub motor.
