Hybrid Analytical Modeling: Fourier Modeling Combined With Mesh-Based Magnetic Equivalent Circuits

This paper presents a hybrid analytical modeling (HAM) method, which integrates a mesh-based magnetic equivalent circuit model with the Fourier modeling approach. This HAM is capable of correctly predicting the electromagnetic field distributions for various 2-D 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 with the sole use of Fourier modeling. The proposed HAM method predicts the force in the geometry with ≥97[%] accuracy with respect to finite-element analysis.
