摘　　要：介绍了凸极无刷直流电动机转子位置检测的电流注入法。该方法是在定子绕组中注放微弱的高频交流信号,通过对端电压的处理,计算出转子的位置。文中利用该方法对启动和正常运转的电动机转子位置进行了仿真,验证了其有效性。This paper describes a current injection method to detect the rotor flux position of the salient-pole brushless DC motor.The method is used to calculate the rotor position by injectiong a small high frequency AC current into the stator windings and processing the stator winding voltages.Then the simulation is made by using this method to estmate the motor's rotor position during the start-up and running periods,and the results show it is valid.
