Wound Rotor Induction Motor Savings TMEIC

Large wound rotor induction motors (WRIM) have been used in some industries for decades. In the cement and mining industries, high horsepower WRIMs are used on large grinding mills, where they have the advantage of controlled starting characteristics and adjustable speed capability. These motors are also used on large pumps in the water and waste industry.

TECO-Westinghouse Wound Rotor Motors

What makes the wound rotor motor a unique induction machine is its rotor. Instead of a series of rotor bars, a set of insulated rotor coils is used to accept external impedances. The rotor windings are similar to those found on a DC armature, with the coils connected together to a set of rings that make contact with carbon-composite brushes.

Wound rotor motor - Wikipedia

A wound-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, the resistance can be decreased.
