Integral Modeling of the Magnetic Field in Ferromagnetic Materials for Electrical Machine Analysis
Year: 2026
Type: conference-paper
Abstract: This paper presents an integral modeling approach for ferromagnetic materials based on an equivalent surface current representation. Analytical methods are widely employed in electrical machine design due to their accuracy and low computational cost; however, modeling ferromagnetic regions remains a challenging task. In the proposed work, ferromagnetic regions are represented by position-dependent equivalent surface currents derived from magnetostatic integral equations, enabling efficient computation of the magnetic flux density. The approach is illustrated through several magnetostatic case studies involving different external magnetic field sources. The obtained results are compared with finite element method (FEM) simulations, demonstrating that the proposed model accurately captures the influence of the relative permeability.
