Consider a three-phase induction motor with a normal torque-speed characteristic. Neglecting the effects of stator resistance and leakage reactance, discuss the approximate effect on the characteristic, if:

(a) The applied voltage and frequency are halved.

(b) Only the applied voltage is halved, but the frequency is at its normal value.
