The main problem in the BLDC motor drive is high torque ripple. One reason for the torque ripple in this motors is the commutation torque ripple. An efficient method to reduce the commutation torque ripple is PWM-MPC . This method reduces the non-commutation phase current ripple by changing the duty cycle of the incoming and outgoing phase current path switches in the commutation. By calculating the speed error and applying it to a PI speed controller, the non-commutation current at the next moment is calculated. The MPC block creates the PWM reference at commutation moments and current PI controller creates the PWM reference at non-commutation moments. The simulation results show using of this method can reduce the electromagnetic torque error by 17%. One of the important problems of feeding BLDC motors is voltage imbalance. It has negative effects on torque and speed and can cause an increase in the current of the coils and then increase the motor operating temperature. This paper investigates the behavior of the drive motor with this method in unbalanced voltage
