Abstract: A method is presented to compute three-dimensional eddy current distributions in laminated media by means of the finite element method. In a first step, the laminated medium is assumed to have an anisotropic conductivity with zero (or very low) value in the direction normal to the laminations. In a second step, the eddy currents within the laminates are computed by solving the quasistatic electromagnetic field individually in each sheet. In these essentially two-dimensional analyses, the boundary conditions are taken from the three dimensional field distribution determined in the first step. Comparisons with results obtained from a finite element model taking account of each laminate prove the validity of the method.Keywords: electromagnetic field, eddy currents, finite element method analysis, laminatesPublished in DKUM: 01.06.2012; Views: 2180; Downloads: 85 Link to full text
