Applications of Electric Drives Electrical Engineering

2021-7-5  Slip-ring type induction motors are suitable for roughing and re-rolling mills where very precise speed control is not required. Their efficiency is low because of wastage of energy taking place in the rotor resistance. There is also abrupt rise in the motor speed when the material leaves the rolling stands.
