介紹了采用ATmega48單片機實現(xiàn)三相無刷直流電機控制器的方法。利用Atmega48獲得帶死區(qū)的脈寬調(diào)制（PWM）、霍爾傳感器的換相處理、正弦驅(qū)動信號的產(chǎn)生和電機轉(zhuǎn)速的控制等功能。采用該方法的優(yōu)點是所需的外圍器件少，成本低。
Abstract:
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.
