Abstract :
The method of detecting the phase terminal voltages without current is to realize Back-EMF zero crossing. MC9S12XDP256 of dual CPU core completed the brushless DC motor. The function it possessed will completely achieve the task of controlling the Brushless DC motor. This paper discusses the theory of Back-EMF and the method of using S12X MCU to control Brushless DC motor motor. The way of Brushless DC motor start-up is designed. The Brushless DC motor is running well and start-up successfully in practice. So the method is proved to be right.
