A 12 pole, 50 Hz synchronous motor has saturated X_{d} = 0.8 pu and X_{q} = 0.5 pu. It is supplying full load at rated voltage of 0.8 pf leading. Draw the phasor diagram and calculate the excitation emf in pu. Calculate its pu synchronizing power per degree elect. and pu synchronizing torque per degree mech.
