Abstract:
The aim of this paper is to introduce and to study the performance of some multiscale finite-element formulations for the eddy
current problem in laminated iron in two dimensions. The case of the main magnetic flux that is parallel to the laminates and assumed
to be perpendicular to the plane of projection is considered. Exact solutions of relevant boundary value problems for eddy currents
are presented. Multiscale formulations based on the magnetic vector potential (MVP) and the single component current vector
potential and on a mixed formulation of the MVP and the current density are discussed. An approach for a multiscale formulation
with the MVP is constructed at the best based on an exact solution.
