滑环式电动机又称三相绕线转子交流异步电动机，在电动机的转子中串联电阻或电阻，这样才能减小起动电流，增大起动转矩，提高功率因数，有效改善电动机的起动性能。

滑环电机是一种旋转电机，它的工作原理基于电动机的电磁感应和电流产生的磁场力。它的转子上安装了一对导电滑环和一对电刷，这些零部件组成了滑环组件，它们的作用是将电源电流输送到转子线圈中，使转子转动。

当电源施加在定子线圈上时，定子线圈中会产生一个磁场。这个磁场会通过转子传导，从而在转子中产生一个感应电动势。转子中的感应电动势会引起的电流流动，这个电流在导电滑环和电刷的作用下流回电源中。这样，转子就形成了一个自激振荡电路，通过交替产生的磁场力和电流的相互作用，使转子旋转。

滑环电机是把电能转换为机械能的一种电机设备。可以分为交流电动机和直流电动机。滑环电机主要由定子和转子组成，它利用定子绕组产生旋转磁场作用于鼠笼式闭合铝框从而形成磁电动力旋转扭矩，滑环电机工作原理是通过磁场对电流受力带动电机转动。受力转动的方向跟电流方向和磁场方向有关。

滑环电机的转速可以通过改变电源的频率和电压来调整。调整电压可以改变电磁力的大小，而调整频率可以影响电机转子中的感应电动势大小，从而影响电机的转速。滑环电机适用于需要高启动转矩和可调速的应用场合，例如起重机、风力发电机等。
