Abstract
This paper presents a method for commutation torque ripple reduction in brushless DC motor (BLDCM) drives. Commutation torque ripple depends on the current ripple. In the proposed method, by adding an extra voltage source to the non-commutating phase, current ripple and so commutation torque ripple is suppressed. The current ripple of BLDC motor in 120° elec. conduction mode is analyzed. The proposed method is confirmed by the dynamic simulation of a 600 W BLDC motor.
