Abstract

Aiming at the torque ripple problem of Brushless DC motor, a new stator flux setting method is proposed on the basis of direct torque control system. Firstly, the basic forming principle of traditional stator flux vector locus of circular and hexagonal is analyzed.And then, a new stator flux linkage setting method based on rotor position and dynamic current mode is proposed.The new stator flux linkage method is applied to the direct torque control system of Brushless DC motor.Theoretical analysis shows that the given flux linkage trajectory is consistent with the expected reference value, the torque ripple is smaller. The simulation results verify its effectiveness and are suitable for BLDCM DTC operation.
