3D FINITE-ELEMENT INVESTIGATION OF THE MAGNETIC-FIELD OUTSIDE ELECTROMAGNETIC DEVICES

This paper is devoted to the computation of the magnetic field radiate d by static inductors and a rotating machine. The authors used a 3D fi nite element program in which the open boundary space was represented either by a geometrical transformation or by the coupling Of finite el ement and boundary integral methods. A comparison of the computed valu es given by the two methods will be presented along with experimental results measured a long distance from the magnetic devices that has be en tested.
