    The damper winding in synchronous motor performs two functions provides starting torque and. prevents hunting in the synchronous motor. When the rotor is rotating at synchronous speed then the relative velocity between the RMF rotating magnetic field of the stator and the rotor is zero. Hence induced EMF in the damper winding is zero.
