Electrical Engineering QUESTION #2149
Question 1
In a DC machine, the purpose of Interpoles is primarily to:
  • Increase the main field flux
  • Reduce the speed of the motor
  • Improve commutation by neutralizing armature reaction✔️
  • Decrease the starting torque
Correct Answer Explanation
Interpoles are small poles placed to neutralize the cross-magnetizing effect of armature reaction and reduce sparking at the brushes during commutation.
