Question: A 2 0 8 - V , - connected, synchronous motor takes 3 0 A from the infinite bus ( supply ) at full load

A 208-V,-connected, synchronous motor takes 30 A from the infinite bus (supply) at full load and 0.866 pf leading. The synchronous impedance of the motor is 0.5+ j6 W/phase. Determine the power developed by the motor. What is the maximum power developed by the motor when the field excitation is held constant?
