A synchronous motor is rated as 250 hp, 4.8 kV connected 60 Hz 12 poles with Xs=0.6 pu and Rs=0.01 pu. The motor rotational losses are 1.5 kW and the excitation power is 6 kW. The motor is supplied by rated voltage at the stator. The motor delivers 2.5 kNm of torque to the mechanical load and maintains a unity power factor at the stator. Calculate the internally generated voltage, the stator current, and the motor power efficiency.
