本应用笔记介绍一种采用dsPIC数字信号控制器(Digital Signal Controller,DSC)或PIC24单片机来实现无刷直流(Brushless Direct Current,BLDC)电机无传感器控制的算法。该算法利用对反电动势(Back-Electromotive Force,BEMF)进行数字滤波的择多函数来实现。通过对电机的每一相进行滤波来确定电机驱动电压换相的时刻。 ...

3-phase Sensor-less Fan Motor DriverAM2355NThe AM2355N is a 3-phase sensor-less DC fan motor driver IC. It senses the BEMF (BackElectro-Motive Force) of the motor in rotation and provides corresponding commutation current tothe motor. Rotation speed can be controlled by PWM input signal. The drivers ...
