A 480 Volts, 60HZ, 50Hp, three-phase induction motor is drawing 50 Amperes at 0.85 power factor lagging. The stator copper losses are 2KW, rotor copper losses are 700W, friction and windage losses are 600W, core losses are 1.8KW, and stray power loss is negligible. Find the following quantities: a. The air-gap power(PAG) b. The power converted(Pcony) c. The output power(Pout) d. The efficiency of the motor
