| Abstract: | The control mode on back-EMF detect of sensorless BLDC motor was studied. Several frequent methods of motor starting were analyzed. The pre-position method using dsPIC30F6010 to realize the starting of sensorless BLDC motor was expounded, and the wave form of phase current and torque were given. The presented method feaures of starting with stability and reliability was veritied by experimental results. |
