Reduction of Cogging Torque and EMF Harmonics in Modulated Pole Machines [PDF]

open access: yesIEEE Transactions on Energy Conversion, 2014
This paper discusses a method for reducing cogging torque and harmonic content of back-electromotive force (EMF) waveforms in modulated pole machines (MPMs). Tooth pitching is applied to a separate phase MPM in order to reduce the most prominent harmonics present in a three-phase MPM's cogging torque.
