摘　　要：研究了一种基于通电相位和通电角度最优化的无位置传感器无刷直流电动机控制方法，该控制方法采用反电势过零检测和预定位起动方法．同时在PWM调制时通电相位和通电角度分别为0°～30°，120°～180°之间的合适值。这样不仅可以提高无刷直流电机的输出转矩和转速。而且可以提高电机的工作效率．The control method for sensorless brushless DC motor by optimizing phase angle and conduction angle is presented in this paper. The hack EMF communication method and rotor pre-setting method used in the control method. In PWM control it gives phase angle an adaptive value between 0°and 30°,and conduction angle an adaptive value between 120°and 180°. So it can not only increase the torque and the speed of brushless DC motor, but also improve the efficiency.
