Wound rotor motor - Wikipedia

A wound-rotor motor, also known as slip ring-rotor motor, is a type of induction motor where the rotor windings are connected through slip rings to external resistance. Adjusting the resistance allows control of the speed/torque characteristic of the motor. Wound-rotor motors can be started with low inrush current, by inserting high resistance into the rotor circuit; as the motor accelerates ...

What is a Wound Rotor Motor and How Does it .

08-09-2020· In wound rotor motors, the rotor is "wound" with wire similar to the stator, with their terminal ends connected to 3 slip rings on the output shaft. These slip rings are attached to brushes and variable power resistor banks, where operators can change the speed of the motor by varying the resistance through the rotor coils.

Rotor (electric) - Wikipedia

Rotor slip provides necessary induction of rotor currents for motor torque, which is in proportion to slip. When rotor speed increases, the slip decreases. Increasing the slip increases induced motor current, which in turn increases rotor current, resulting in a higher torque for increase load demands. Wound rotor
