Axial flux permanent-magnet (AFPM) machines are essentially analyzed by the three-dimensional (3-D) finite element analysis (FEA) because AFPM machines have different cross-sectional shapes along the radial direction. The biggest disadvantage of 3-D FEA is that it takes much computing cost and time. Therefore, there is much research to reduce computing cost and time by using the two-dimensional (2-D) FEA with equivalent 2-D models. The accuracy varies depending on the number of equivalent models because of the different cross-sectional shapes along the radial direction. This paper compares the accuracy of the equivalent models using 2-D FEA by the shape of the magnet.
