Briefly explain why the three-phase synchronous motor will not start if an attempt is made to first energize the DC field circuit and then apply the three-phase voltage to the stator windings.
What will be an ideal response?
If an attempt is made to start a three-phase synchronous motor by first energizing the DC field circuit and then applying the three-phase voltage to the stator windings, the motor will not start because the net torque is zero.
