Abstract
The paper deals with a numerical model for the evaluation of electromagnetic fields in one steel lamination under the influence of a rotating magnetic flux, taking into account anisotropy effects. For this purpose, a detailed material model, described by a differential permeability tensor, is included in the macroscopic electromagnetic field calculations in one lamination. The study leads to a more realistic numerical modeling of the electromagnetic phenomena inside electric and magnetic conducting laminations due to anisotropy effects. The model has been verified experimentally by the reconstruction of the coenergy function starting from unidirectional measurements on Epstein strips cut along different directions with respect to the rolling direction and by the comparison of measured and calculated H loci for circular flux excitations.
