Abstract :
Brushless DC motor system, the rotor position signal is essential for the normal operation of the entire system. Past rotor position sensor signal is detected by the position, but sensors are more affected by environmental drawbacks. Currently, no position sensor control technology has become a hot topic. In this paper, using back-EMF zero-crossing detection sensors BLDCM position of the rotor system, and its commutation strategy, and the simulation study.
