A 480 V permanent magnet ac motor is consuming 10 kW at power factor 0.80 lagging. Its speed is 1800 rpm. The winding resistance is 0.5 ohms per phase. Core losses are 100 W. Mechanical losses are 250 W. Stray losses are 1.5% of the input power. Calculate the power converted to mechanical power, the output power (9.26 kW), the output torque, and the motor efficiency (92.6%).
