Wound rotor motor Wikipedia

A woundrotor 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. Woundrotor motors can be started with low inrush current, by inserting high resistance into the rotor circuit as the motor accelerates, the resistance can be decreased.
