A 208V Y-connected synchronous motor is drawing 50 A at unity power factor from a 208Vpower system. The field current flowing under these conditions is 2.7 A. Its synchronous reactance

is 1.6 N. Assume a linear open-circuit characteristic. Find V, and E, for these conditions.'A Find the torque angle ð. What is the static stability power limit under these conditions? O How much field current would be required to make the motor operate at 0.80 PF leading? What is the new torque angle in part (d)?
