| 摘 要： | 介绍一种采用单片机驱动无传感器直流无刷电动机的方法，它在PWM导通期间对电机端电压进行采学检测，判断绕组反电势过零点的到达时间，并通过简单的线性运算进行误差校正，推算三相功率器件的换向导通时间。实验证明，这种方法检测精度高，抗干扰能力强，硬件检测电路简单，实现容易。

| Abstract: | A method that drived the sensorless brushless DC motor using MCU was introduced.It sampled and detected the voltage of the motor's stator coils during the PWM's switching-on,obtained the right time when back-EMF reached the zero point.And then the errors were revised through the simple linear operation and the commutation time of three-phase power transistor was concluded.As the result's show,the method proved to be high precise and strong anti-interference ability.At the same time,the hardware circuits of the detection was simple and easy for realization. |
