A 480 V, 60 Hz, 50 hp, 3 phase induction motor is drawing 60 A at 0.85 PF lagging. The stator copper losses are 2 kW, and the rotor copper losses are 700 W. The friction and windage losses are 600 W, the core losses are 1800 W, and the stray losses are negligible. Find: The air gap power PAG conv The power converted P The output power Po out The efficiency of the motor PAG P = out load m Air-gap power Pin = √3 VTIL cos 0 Pin = 3V 1 cos Ja Pcore PSCL (Core (Stator copper loss) losses) Pconv T PRCL (Rotor copper loss) Tindwm Pfriction and windage P stray (Pmisc.)
