无传感器无刷直流电机最佳触发信号的获取

Acquisition of Optimum Commutation Signal in a Sensorless Brushless DC Motor

论述了怎样通过线反电势过零点来获取定子最佳换相信号 ,给出了实用电路 ,并提出了通过埋置测试线圈来获取换相信号的新方法。

In this paper, the author focuses on how to get the optimum commutation signal in stator coil according to back EMF and puts forwards a new method to get the optimum commutation signal through installing sensitive coil.
