Abstract: Abstract:The most significant assumptions in the subdomain technique (i.e., based on the formal resolution of Maxwell's equations applied in subdomain) is defined by: The iron parts (i.e., the teeth and the back-iron are considered to be infinitely permeable, i.e., µ iron → +∞, so that the saturation effect is neglected. In this paper, the authors present a new scientific contribution on improving of this method in two-dimensional (2-D) and in Cartesian coordinates by focusing on the consideration of iron.

“…In most semi-analytical models based on the subdomain technique, the iron parts are considered to be infinite permeable due to the variation of material proprieties in the various directions, so that the saturation effect is neglected [16][17][18]. The first paper introducing the iron parts in the magnetic field calculation by using the subdomain technique is [1], where the authors solve partial differential equations (PDEs) of the magnetic potential vector in Cartesian coordinates in which the subdomains connection is performed directly in both directions (i.e., x-and y-edges). The 2-D magnetostatic model has been applied to an air-or iron-cored coil supplied by a constant current.…”

“…It allows the evaluation of the local distribution of flux densities in the iron parts with a global saturation, does not have numerical convergence problems contrary to others models and would easily introduce the current penetration effect in the conductive materials. The semi-analytical solution is exact as in [1] and does not use the Taylor polynomial to satisfy the r-edges BCs contrary to [33,34]. For example, it was applied to an air-or iron-cored coil supplied by a constant current.…”
