频敏变阻器是一种由铸铁片或钢板叠成铁心,外面再套上绕组的三相电抗器,接在转子绕组的电路中,其绕组电抗和铁心损耗的决定的等效阻抗随着转子电流的频率而变化.频敏变阻器实际上利用转子频率f2的平滑变化达到使转子回路总电阻平滑减小的目的。频敏变阻器实际上是一个特殊的三相电抗器，它有一个三柱铁芯，每个柱上有一个绕组，三相绕组一般接成星形。频敏变阻器的这一频率特性非常适合于控制异步电动机的启动过程。频敏变阻器是一种无触点电磁元件，相当于一个等值阻抗。
频敏变阻器适用于容量自22Kw、50Hz、三相交流绕线型异步电动机作为轻载及重轻载偶尔起动用(例如：水泵、空压机、轧钢机、空气压缩机等)，或重复 短期工作制起动用(如：容量自2.2Kw至125Kw的桥式吊车、升降台、矿用传递带等)。
