A novel dual-stator flux switching permanent magnet machine with six stator slots and four rotor poles configuration

The purpose of this paper is to introduce a novel dual-stator six stator slots four rotor poles flux switching permanent magnet machine that is viable for operation. The conventional six slots four poles topology suffers from asymmetrical flux linkage and severely unbalanced back-EMF, which makes it unfeasible. The proposed dual-stator structure utilizes windings in the second stator to produce a corresponding flux linkage that cancels the even order harmonic components in the first stator winding. The resulting flux linkage, back-EMF have no even order harmonics and are almost sinusoidal waveforms. The performance of the proposed machine is validated by analytical and finite element analysis.
