This paper presents a 3-D analytical magnetic field analysis of an air-cored axial flux permanent-magnet machine The 3-D analytical magnetic distribution is established using the magnetic scalar potential and modified BESSEL functions in the cylindrical coordinate system. The analytical magnetic field distributions and electromagnetic force are derived and verified by the computational results using finite element method.
