摘　　要：当电枢电流换向时,无刷直流电机定子绕组的电感和反电势导致电流的波动,从而导致了转矩的波动。文中提出应用傅立叶级数系数的电流控制算法,能明显减少转矩波动。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.
