摘　　要：为提高无刷直流电动机故障诊断水平,在Simulink下建立了带霍尔位置传感器的无刷直流电动机驱动系统模型。针对逆变桥功率开关管短路、开路及霍尔传感器缺相等故障进行了仿真,得到了相应的特征波形。对各类故障进行了理论上的分析,分析结论为无刷直流电机的故障诊断提供了科学的参考。A brushless DC motor drive system model based on Simulink with Hall sensors is constituted to provide references to fault diagnosis.The faults including short circuit,open circuit in power transistors and phase-fault in Hall sensors are simulated and performance waveforms relevant to different faults are obtained.Results of fault simulation are analyzed theoretically and references to fault diagnosis of brushless DC motor are provided.
