异步电动机的制动方法一般有两类:机械制动和电气制动。机械制动常用的方法有:电磁抱闸和电磁离合器制动。常用的制动方法有能耗制动、反接制动和回馈制动。

反接制动的优点是:制动力强，制动迅速。缺点是:制动准确性差，制动过程中冲击强烈，易损坏传动零件，制动能量消耗大，不宜经常制动。因此反接制动一般适用于制动要求迅速、系统惯性较大，不经常启动与制动的场合。

能耗制动的优点是制动准确、平稳，且能量消耗较小。缺点是需附加直流电源装置，设备费用较高，制动力较弱，在低速时制动力矩小。所以，能耗制动一般用于要求制动准确、平稳的场合。

回馈制动是一种比较经济的制动方法。制动时不需改变线路即可从电动运行状态自动地转入发电制动状态，把机械能转换成电能再回馈到电网，节能效果显著。缺点是应用范围较窄，仅当电动机转速大于同步转速时才能实现发电制动。
