The interpoles in dc machines have tapering shape in order to

  • AReduce the overall weight
  • BReduce the saturation in the interpole
  • CEconomic on the material required for interpoles and their windings
  • DIncrease the acceleration of commutation
Correct Answer : (B)

Reduce the saturation in the interpole

Hints :

Torque developed in an electromechanical energy conversion device depends upon


In electromechanical energy conversion devices (e.g generators and motors) a small air gap is left between the stator and the rotor in order to
