The speed controls of three phase induction motor from rotor side
... Now if we increase rotor resistance, R2 torque decreases but to supply the same load torque must remains constant. So, we increase slip, which will further results in decrease in rotor speed. Thus by adding additional resistance in rotor circuit we can decrease the speed of three phase induction mot ...
