Abstract

In this paper, eddy current compensation method of 2D finite element method(FEM) is studied compared with 3D FEM. The result of eddy current loss of permeant magnet is different from 3D FEM result because current loop of the inside of permanent magnet can not expressed by 2D FEM. In order to reduce the error between 2D and 3D FEM, permanent magnet conductivity is compensated considering current loop of magnet shape according to length and width.
