Abstract
The main theme of this paper is to present a unified approach to back-EMF detection of brushless DC motor drives without using any current and Hall sensors. Theoretical analysis of back-EMF detection is presented, and followed by the relationship between PWM techniques and back-EMF detection. It will be shown that the back-EMF detection depends upon the PWM techniques and the method is required to be slightly modified as the PWM technique is changed. Experimental results derived from BLDCM drives without using any current and Hall sensors fully confirm the theoretical analysis
