Please help me with this Q.
> A 440V, 3 phase 50Hz, 6-pole, star connected squirrel cage induction
> motor has a stator resistance of 0.05ohm/phase and a magnetizing
> reactance of 8.5ohm/phase. The rotational losses of the motor
> including the core losses are 2,500 W. The speed of the motor at full
> load is 975rpm. The blocked-rotor test data of the motor are as
> follows:
>
> V= 90V I = 90A P=2,915 W

the
> motor
> (3) Determine the developed torque and the output power of the motoe
