摘　　要：PSpice库中的无刷直流电动机模型只适用于正弦波无刷直流电动机仿真。文章建立了方波无刷直流电动机的PSpice仿真系统,该系统还可以仿真反电势平顶宽度小于120°的无刷直流电动机,而且实现了高压自举驱动,为自举电路的分析提供了有效的手段。仿真结果与实验结果相符合,证明了建立的仿真系统是正确的。The model of Brushless DC Motor that PSpice provided is only suit for sinusoidal BLDCM simulation. A simulation system for trapezoidal BLDCM is rebuilded. This system also adapts for trapezoidal BLDCMs simulation less than 120° in width, and implements high voltage bootstrap drive which provides effective way for the analysis of bootstrap circuit. Simulation results and experimental results show excellent agreement, which have shown the validity of the simulation system rebuilt.
