N2 - An axial flux permanent-magnet (AFPM) motor requires 3-dimensional (3-D) modeling and analysis in order to describe completely its 3-D behavior. Although the 3-D finite element analysis (FEA) provides accurate solution, its computational cost limits its use as a design tool. To address this problem, a 3-D field reconstruction method (FRM) is introduced as an alternative to the 3-D FEA. In this paper, an AFPM motor is designed and analyzed by using the 3-D FRM. The prototype does not have pole shoe on the teeth, thus it has high cogging torque due to high slot harmonics. Therefore, skewed PMs are employed on the rotor for cogging torque mitigation. This paper presents the improved 3-D FRM to take into account the magnet skew effect. To verify a validation of the proposed 3-D FRM, the analysis results are compared with the ones estimated by 3-D FEM.
