Abstract
The eddy current fields in a laminated iron core and a single lamination, where the fields are considered as the 2-D and the 1-D problems, respectively, are analyzed. Then a new and simple formulation of equivalent conductivity in the direction normal to the laminations is derived by equating the eddy current loss expressions obtained from the above two problems. The validity of the formulation is verified by comparing the eddy current losses, calculated with the finite-element method using the proposed conductivity formulation and a long known formula, in an analyzed model.
