New approach for Accurate Prediction of Eddy Current Losses in Laminated Material in the Presence of Skin Effect with 2D FEA

摘要

The integrated iron loss models in FE software overestimate the eddy current losses at high frequencies due to the presence of the skin-effect. This paper presents a simple detour for accurate prediction of eddy current losses in laminations with two-dimensional (2D) finite element analysis (FEA). An experimental set-up along with the simulation models is used to demonstrate the validity of the method. The utility of this method in loss separation and identification of loss coefficients is also illustrated.
