A 208-V Y-connected synchronous motor is drawing 50 A at unity power factor from a 208-V power system. The field current flowing under these conditions is 2.7 A. Its synchronous reactance is 0.8Ω. Assume a linear open-circuit characteristic.

(a) Find the torque angle δ.

(b) How much field current would be required to make the motor operate at 0.78 PF leading?
