- Abstract
- This paper presents the electromagnetic analysis and experimental verification of PMSM considering axial flux leakage and endwinding leakage inductance based on the subdomain method. To consider the axial leakage flux, an analytical solution is derived by applying the corrected relative permeability to the slot and slot opening of the simplified analytical model. The leakage inductance due to end-winding is divided into self and mutual, calculated separately, and compensated with the leakage component of synchronous inductance. The validity of the analysis results calculated from the proposed method was compared with the results calculated from the 2D and 3D finite element methods. In particular, through the performance evaluation results under no-load and rated-load conditions, the proposed analytical results were validated. Therefore, the proposed analytical method can predict an accurate characteristic analysis by considering the end-winding and the axial leakage flux in the design stage.
