摘要
分析了反电势过零检测法控制无位置传感器无刷直流电机的基本原理,设计了检测电路;对电路中滤波所带来的转子位置移相进行误差分析,提出了相位修正的方法,并通过实验进行了验证。
This paper presents the basic principle of sensorless brushless DC motor eommutated by using the zero-crossing method of back EMF, and designs the detection eircuit. Analyze the rotor seat phase shifting which the filter brings to the electric circuit, proposes the phase revises method, carries on the confirmation through the experiment.
