    This paper proposes an improved Quasi-3D analysis method for rapid magnetic field prediction in axial flux permanent magnet motors. The proposed method accounts for the effects of the permanent magnet overhang structure. The conventional Quasi-3D approach simplifies analysis by radially segmenting the motor, evaluating each region with 2D finite element analysis, and integrating the results to predict overall performance. However, conventional Quasi-3D methods have limitations in accurately modeling permanent magnet overhang, which results in discrepancies in performance predictions. To resolve this issue, the proposed Quasi-3D approach employs an equivalent analytical model that adjusts the permanent magnet operating points. This adjustment ensures that the magnetic energy aligns accurately with experimental data in electromagnetic analyses. The validity of the proposed approach is confirmed via comparisons with experimental verification results, thus demonstrating the enhanced accuracy of the method in predicting the performance of axial flux permanent magnet motors with permanent magnet overhang structures.
