Electrical Machines
The introduction of interpoles in between the main poles improves the performance of a dc machine, because

 the inequality of air-gap flux on the top and bottom halves of the armature is removed
 the flux waveform is improved with reduction in harmonics
 the interpoles produce additional flux to augment the developed torque
 a counter-emf is induced in the coil undergoing commutation
