摘要
Abstract
The control of Brushless DC motors is similar to DC motors in the non-commutation process. Three-phase is involved in electromechanical energy conversion in the commutation process, so a new analytical method of Brushless DC motors was proposed employing the three-phase AC motor coordinate transformation theory. The constraints of commutation currents and commutation time were obtained. And the graphical method analysis of the brushless DC motor commutation torque ripple suppression method was proposed, combined with the constraints of the inverter output voltage. The control method was deduced with shortest commutation time. This method was intuitive and easy to understand compared with the circuit solving method. Finally, the feasibility and effectiveness of the method was verified by experiments.关键词
