A 6 pole 60Hz induction motor is operating at 1172 RPM. If input power is 1.0MW, with combined stator copper and iron losses at 5% of input power, then what will the rotor copper losses be (numeric answer only expressed in kW – Hint: you must find power across the air gap and % slip to solve this problem)?
