摘　　要：无刷直流电机转子位置和转子磁通与定子绕组产生的磁链信号密切相关。该文建立了和转子磁链直接相关的函数,据此获取转子位置信息,经过处理可获得无刷直流电机的换向信号。该方法不依赖于转子速度,可保证无刷直流电机转速在较大的运行范围内有效控制。据此基于Matlab/Simulink进行仿真研究。仿真研究结果证明了该方法的可行性和高效性。The rotor positon and flux linkage of brushless DC motor（BLDCM） are closely related with each other. A function on the flux linkage has been built according this to get the signal of the rotor position. After processed this signal can be used to control the converter of BLD- CM. This method isn＇t depend on the rotor speed. So the BLDCM under this method has a wider speed regulation. A simulation control system has been set up on Matlab/Simulink. Results are illustrated to show verv good dynamic performance for a wide range of operation conditions.
