“…Instead the Halbach PMs is adopted in [8]. The machine with interior PMs have less eddy current losses in PMs than that with surface mounted PMs, but there is limited amount of work on the axial flux interior permanent magnet (AFIPM) machines [9][10][11][12][13][14]. For most interior permanent magnet (IPM) machines, the non-uniform air gap is adopted to achieve a sinusoidal distributed air gap flux density and back electromotive force (EMF) waveform [15][16][17][18][19], and the best shape of rotor surface is revealed in [19] theoretically.…”

In this paper, the two-layer spoke-type (TLST) axial flux interior permanent magnet (AFIPM) machine is proposed. Simple flux barriers are added to optimize the air gap flux density, in which way there is no need to change the surface of the rotor. The optimization principle is revealed and the advantages of the TLST AFIPM machine compared with the spoke-type (ST) AFIPM machine are clarified. An optimization design process based on magnetic equivalent circuit combined with idealized and improved air gap flux density waveform is proposed, in which way the calculation time is saved by avoiding an excess of finite element method (FEM) simulations. Finally, 3D FEM simulation is adopted to verify the optimization results.
