摘　　要：针对无位置传感器技术在电机零速和低速时反电势不存在或难以检测的问题,依据绕组电感随磁场变化的原理,提出并实施了利用高频脉冲电压检测转子零初始位置并起动电机的方法;通过对控制方法的实验验证,证明该方法比传统"三段式"法有良好的起动性能。B-EMF is inexistent or hard to detect on the problem of technology of sensorless control when the motor is at standstill and at a low speed. According to the principle of winding inductance varies from magnetic field, technique is put forward and implemented on making use of a detectable voltage that gen- erates high-frequency pulses which can detect the initial location of rotors and operate motors. It would be proved that this technique is more prominent than traditional syllogism by verifying the experimentation of controlling technique.
