Since the excitation emf is zero, heavy currents would be drawn by the armature if connected to the rated voltage supply. Also, if the voltage is large, the reluctancetorque due to saliency may bring the rotor in synchronism with the rotating flux (ie.the synchronous machine will run as a reluctance motor)
