摘要
分析反电势过零检测法控制无位置传感器直流无刷电机的基本原理,并设计检测电路,对电路中滤波所带来的转子位子移相误差进行分析,提出相位修正的方法,通过实验进行验证。
This paper presents the basic principle of sensorless brushless DC motor commutated by using the zero-crossing method of back EMF, and designs the detection circuit. Analyze the rotor seat phase shifting which the filter brings to the electric circuit, proposes the phase revises method, carries 3n the confirmation through the experiment.
