摘要
介绍了采用ATmega48单片机实现三相无刷直流电机控制器的方法。利用Atmega48获得带死区的脉宽调制(PWM)、霍尔传感器的换相处理、正弦驱动信号的产生和电机转速的控制等功能。采用该方法的优点是所需的外围器件少,成本低。
The method of 3-phase brushless DC motor control based on ATmega48 is presented in this paper.The system uses ATmega48 to generate PWM signals with dead-time, hall sensors signals commutation, sine driving signal and rotational speed of motor.Using this method ,the needed external devices are few, the cost is low.
