This paper present a dive strategy to reduce torque ripple of a permanent magnet Brushless DC Motor(BLDCM)with short 120' flat top Back Electromotive Force(BACK-EMF). In this strategy, the phase Back-EMF is divided into four sections. Then, in each section the phase current is regulated by corresponding PWM duty ratio to compensatethe torque ripple caused by imperfect Back-EMF. A program based on this strategy has been implemented in MATLAB@Simulink. The validity of the presented method is verified by simulation results
