| Abstract: | To achieve sensorless control of brushless DC motors(BLDCM),rotor position is extracted from back-EMF.Traditional mechanical position sensor was replaced and this will effectively open the way for full penetration of this motor drive into high-cost,high reliability,and large volume applications.A review of the literature addressing BLDCM sensorless control based on back-EMF was provided.The advantages and disadvantages of different sensorless methods were discussed in details. |
