摘要
本文首先引入脉冲电流换向函数和正弦波电流换向函数的概念，对“方波运行原理”和“正弦波运行原理”的无刷直流电动机的力矩波动进行了分析。文中给出选择电流换向函数的一般准则，并介绍其实现的基本途径。
This paper first introduces the concept of pulse current commutation function andsinusoidal current commutation function,Different current commutation functions directlyaffect the output and the smoothness index of torque of motors,The paper also gives outthe general criterion for the choice of current commutation function and introduces basicmeans of realizing current co mmutation function.
