© 2017 IEEE. The electrical machines are gaining more and more attentions nowadays, especially for the electric vehicle application. Compared with the radial flux machine, the axial flux machine can have higher torque density and efficiency due to its tight structure. However, most of the axial flux machines are designed with the surface mounted permanent magnets (PMs) rotor, where the reluctance torque ability is reduced. To improve the torque ability of the axial flux machine, a new axial flux interior permanent magnet machine (AFIPM) is proposed and analyzed in this paper. The rotor of the proposed AFIPM is manufactured by the rolling the electrical steels as a ring core, then the PMs are inserted in the holes of the rotor ring, the axial side of the rotor ring is designed with the several different steps to eliminate the harmonics of the back EMF as well. The static performance and electromagnetic parameters of the AFIPM is calculated and it shows that the reluctance torque ability of the AFIPM is very good, based on the 3D finite element method (FEM) and frozen magnetic permeability technology.
