Abstract :
This paper introduces four PWM modes used in sensorless brushless DC motor control systems, and analyzes their different influences on the commutation torque ripple in detail. The authors then select the best PWM mode in four given types to reduce commutation torque ripple of BLDC motors. Simulation and experimental results prove that the selection is both correct and practical
