Jul 01, 2014 A Wound Rotor Induction Motor (WRIM] is a special induction machine with a three-phase wound stator, and the rotor also has a three-phase winding, usually connected in a wye (or star) circuit. The three terminals of the rotor winding are connected to separate slip rings, which are normally connected to a variable resistance such as a liquid ...
Three Phase Induction Motors ACI Controls
The wound-rotor motors are normally used in loads with high inertia or high resistive torque at startup. They are also used when starting current limitations are present in the power supply system. They are used to drive loads such as: ball mills, cement mills, fans, exhaust fans, shredders and rolling mills employed in the cement, mining and steel industries, among
