Q.During hunting of synchronous motor

  • ANegative phase sequence currents are generated
  • BHarmonics are developed in the armature circuit
  • CDamper bar develops torque
  • DField excitation increases
Correct Answer : (C)

Damper bar develops torque

Hints :

During hunting of synchronous motor Damper bar develops torque.


An ideal synchronous motor has no starting torque because the 


The armature current of a synchronous motor on no load
