What is the role of interpoles in DC motors?
What will be an ideal response?
Commutating poles or interpoles are very small pole pieces that are placed midway between the main pole pieces. The interpoles are wound with a few turns of heavy wire. As with the main pole pieces, the interpoles are also wound in an alternate clockwise and counterclockwise manner. The pole pieces are connected permanently in series with the armature brush holders and are considered to be a part of the armature circuit. Interpoles counteract the distortion of the field magnetism caused by the rotation of the heavily magnetized armature in the field flux. As a result, sparking or arcing at the brushes is reduced.
