A 220-W, 2 pole, 155-V 60-Hz single phase induction motor delivers rated output at a slip 10%. The total copper loss at full load is 25 Watts. Calculate the full load efficiency and the rotor copper loss caused by the backward field. Rotational losses maybe assumed to be 25 watts. Neglect stator copper loss.
