When the stator windings are connected in such a fashion that the number of poles are made half, the speed of the rotor of a synchronous motor

In a synchronous motor, the breakdown torque is

A 3-phase synchronous motor is running clockwise. If the direction of its field current is reversed

Due to which of the following reasons a synchronous motor fails to pull into synchronism after applying D.C. field current?

When the rotor speed, in a synchronous machine, becomes more than the synchronous speed during hunting, the damper bars develop
