The power input to the rotor of a three-phase induction motor is 33.2 kW. If the slip is 5% and the stator losses are 400 W per phase, determine the following: (a) Rotor copper loss per phase in watts. (3) (b) Total mechanical power developed by the rotor in kW. (2) (c) The output power in kW of the motor if friction and windage losses are 250 W per phase. (2) (d) The input power to the motor in kW. (2) (e) % Efficiency of the motor, neglecting rotor iron loss.
