Explain important functions served by the damper winding in a synchronous motor.

Important functions of damper winding in a synchronous motor: 
  • The oscillatory motion of the rotor about the operating point is considerably reduced in amplitude and rotor quickly returns to the steady position. 
  • Providing starting torque like an induction motor.
  • At starting, the rotor achieves a speed close to synchronous speed and the rotor and stator fields lock into each other as soon as field excitation is switched on.
