Novel dual-rotor single-stator axial flux switching permanent magnet machine with even harmonic elimination topology

This paper proposes a novel 6 slot-4 pole axial flux switching permanent magnet machine using dual-rotor single-stator. The analytical method is used to find offset angle to eliminate even harmonics of flux linkage and back-EMF of a conventional 6 slot-4 pole topology. The analytical method is verified with finite element analysis. Proposed novel topology is also compared with a conventional dual-rotor single-stator 6 slot-4 pole axial flux switching machine. The simulation results prove that the proposed topology effectively eliminates even harmonics in the axial flux switching machine.
