摘　　要：介绍应用于家用空调方波型无位置传感器无刷直流电机压缩机负载的变速控制系统的结构和原理 ,提出了一种超前 6 0°-ε直接检测换相点的方法以实现无位置传感器无刷直流压缩机的控制 。The paper introduces the configuration and principle of the control system for position sensorless square wave BLDC motor with the load of household airconditioner compressor. The leading 60°- ε direct detective commutation point is brought forward and the control of position sensorless BLDC motor compressor is realized. The results of experiment prove that the detection and control method can effectively improve the operative reliability of the system.
