A 480 V permanent magnet ae motor is consuming 10 kW at power factor 0.80 lagging. Its speed is 1800 rpm. The winding resistance is 0.5 W per phase. Core losses are 100 W. Mechanical losses arc 250 W. Stray losses arc 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%).
