【Abstract】 The Brushless DC motor has many good characters. However, when armature current is commutated, the current ripple is generated by the motor inductance components in stator windings and back-EMF.This current ripple caused to torque ripple. In this paper, a current control algorithm using Fourier series coefficients is proposed. This algorithm can minimize torque ripple obviously.更多还原
