无刷直流电动机系统的波动力矩抑制方法

Methods of Suppressing Ripple Torque of the BLDC Motor System

波动力矩对无刷直流电动机系统性能有很大影响，电机系统的正弦化设计可以从原理上消除波动力矩；介绍了抑制波动力矩的各种方法。

Ripple torque greatly affects the performance of the BLDC motor system.The BLDC motor system is free from ripple torque in principle by sinusoidal design.The methods of suppressing ripple torque are discussed in the paper.
