BLDCM Commutation Torque Ripple Strategy Optimization

Abstract:

First of all, this article creates the mathematical model of blushless DC Motor. Secondly, analysis the reduction theory of commutation torque ripple. Finally, put forward a strategy to reduce the commutation torque ripple from the low-speed level and high-speed level. This method guarantee equal between current decline rate of shutdown phase and current rising rate of opening phase during commutation, thus keep the current of un-commutation stable. Build a real brushless DC motor control platform for experimental verification, the proposed strategy of brushless DC motor commutation torque ripple is suppressed effectively.
