A study of voltage control method for torque pulsation factor reduction for home applications integrated BLDC motor drive

In this paper, a voltage control method is proposed for home applications small BLDC motor without current control. The small BLDC motor without current control should be caused noise and vibration. This is because when phase transformation section, the torque ripple is occurred by a current fluctuation of non-commutated phase. To solve this problem, this paper proposes the torque pulsation factor reduction method by overlapping voltage control.
