Design and performance characterization of a novel low-pole dual-stator flux switching permanent magnet machine

The purpose of this paper is to characterize the performance of a novel dual-stator six slot four pole (6/4) flux switching permanent magnet machine. The proposed dual-stator 6/4 topology eliminates even order harmonics in the flux linkage and back electromotive force, which are present in the conventional single stator topology. The resulting back electromotive forces of the proposed dual-stator machine are balanced and sinusoidal waveforms. Sizing equations for the machine are studied based on the flux linkage harmonic contents and generalized sizing laws and performance of the machine is characterized. Various loss components such as copper loss, iron loss, and magnet loss are evaluated. The properties of the proposed machine are verified by finite element analysis studies.
