A wound rotor induction motor has a stator like the squirrel cage induction motor, but a rotor with insulated windings brought out via slip rings and brushes. However, no power is applied to the slip rings. Their sole purpose is to allow resistance to be placed in series with the rotor windings while starting.

Ball Mill Drives - Metallurgist & Mineral Processing Engineer

Motors considered are the squirrel cage motor, wound rotor motor, and synchronous motor. One important advantage of the synchronous motor is the possible correcting of power factor within your operation, through its use. When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pull-in torque, and 225% pull-out torque.
