This paper proposes a novel approach for calculation of axial end leakage flux of the surface-mounted PMSMs. In order to calculate the axial end leakage flux using the 2-D FEA, the leakage magnetic flux in the axial direction is reflected to the 2-dimensional model by adding a factor to the permeability of the slot. The factor applied to the slot permeability is calculated by the equivalent magnetic circuit (EMC) method. At this time, the permeability factor is calculated by considering the main leakage path in the slot and the leakage path in the axial direction. The effectiveness of the proposed method is verified by comparing the results of the proposed method with the experimental results and the conventional 2-D FEA results and 3-D FEA results.
