A 3 phase induction motor is fed by a 3 phase ac regulator to change the stator voltage. The variation in speed will be more if
load torque is constant
load torque increases with increase in speed
load torque decreases with increase in speed
either (a) or (b)
Correct Answer:
load torque increases with increase in speed
Explanation:
If load torque is constant, the change in speed is very small.
