  • Abstract
    This work presents a new modeling strategy to account for the energy stored in the volume around the air gap in gapped magnetic components. The approach is based on the Schwarz-Christoffel transformation, which has been extended to axisymmetrical magnetic components. The results have been validated by means of comparisons with analytical expressions (no fringing flux consideration), 2D FEA based models and actual measurements. It is shown that the accuracy of the proposed method is very high when the assumptions of the model are fulfilled
