| Abstract: | According to the theory of optimal modulation of the voltage control vector of the inverter, this paper presents an optimal commutation strategy with PWM control method of constant frequency sampling based on the non-commuting current, in order to improve the performance of the torque due to commutation in brushless DC machines. This strategy can attenuate the torque ripple due to commutation and minimize its duration effectively. The experimental results indicate that above strategy is feasible. |

| Keywords: | Voltage control optimal commutation torque ripple |
