A 2-hp, 120V, 4 pole, three-phase,Y-connected, synchronous motor has a synchronous impedance of 0.2 +j6Ω/phase. The friction and windage loss is 20W, the coreloss is 35W, and the field-winding loss is 30W. Determine the powerangle and the efficiency of the motor when it delivers the ratedpower at a unity power factor.
