Hybrid analytical modeling : fourier modeling combined with Mesh-based magnetic equivalent circuits

This paper presents a hybrid analytical modeling method which integrates a mesh-based magnetic equivalent circuit model with the Fourier modeling approach. This hybrid analytical modeling is capable of correctly predicting the electromagnetic field distributions for various two-dimensional geometries. The generalized approach of the presented hybrid modeling concept, makes the modeling technique applicable to a wide range of electromagnetic devices. By only meshing the parts of the domain in the vicinity of the high permeable materials, the increase in computational effort is limited compared to the sole use of Fourier modeling. The proposed hybrid analytical modeling method predicts the force in the geometry with 97 [%] accuracy with respect to finite element analysis.
