Consider a 480-V, 50-Hz, three-phase induction motor that consumes 80 A at 0.85 PF lagging The stator and rotor copper losses are 2 kW and 800 W. The friction and windage losses are 600 W. The core loses are 1.6 kW. The stray losses are negligible Find: • The air-gap power PAG • The converted power Pconv • The output power Pout • The efficiency, η, of the motor
