A three-phase, 4-pole IM draws 55kW real power from a three-phase 60Hz feeder. The copper and iron losses in the stator amount to 4kW. If the motor runs at 1740 rpm, draw power flow and calculate: a) the airgap power. b) the rotor loss. c) gross mechanical power. d) if the mechanical loss is 2kW, calculate the efficiency of the motor.
