CHART AND EXPRESSIONS FOR EDDY CURRENT LOSSES CALCULATION IN STEEL LAMINATIONS DERIVED FROM FINITE ELEMENT NUMERICAL RESULTS IN 2D

摘要

A chart and a set of expressions obtained from 2D Finite Element solutions are presented. These allow the 2D eddy current losses calculation for any steel lamination considering skin effect, thickness and width, in the linear zone of the magnetization curve. A comparison between the numerical results and the obtained by the proposed expressions shows a very good agreement.
