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 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 ANSWER DOWNLOAD EXAMIANS APP
