A synchronous motor is connected to a 3-phase system such that the effective voltage for 1 phase is E = 2400 V. The inductance is Xs = 2 ohms and the current per phase is I = 900 A. The excitation voltage E0 = 2800 V.
a- Draw the phasor diagram and determine the electrical torque angle θ.
b- Determine the active power per phase (Hint: active power is given by (E0E/Xs)sinθ).
c- Determine the power factor of the motor.
d- Determine the reactive power per phase.
