摘要
分析了无刷直流电动机在换相时续流对电流和电压的影响，并比较了在四种ＰＷＭ模式中续流所产生的脉动电流，提出了当采用ｏｎｐｗｍ调制方式时，续流所产生的脉动电流最小，对系统的影响也小。
This paper analyzes the effect which the flywheel takes on the current and voltage of the BLDCM during the commutation. The ripple currents produced by the flywheel with the different PWM mode are compared. It is deduced that the minimal ripple current will be produced with onpwm PWM mode.
