Abstract :
[en] A subproblem finite element method is developed for efficient modeling of lamination stacks in magnetic cores. Their homogenization is first performed followed by local corrections in certain thin regions separately, surrounded by their insulating layers and the remaining thin regions kept homogenized. Accurate determinations of Joule losses are obtained.
