“…Table 5 shows the zcomponents Bz of average flux densities in the center pole (α-β) and yoke (γ-δ). Table 6 shows the z-component Fz of electromagnetic force (9,10]. Figures 5 and 6 show the z-directional component Bz of flux density at the mid-point P 1 (0, 0, 25.75) and at the edge P 2 (12.5, 5, 25.75) in the gap shown in Figure 2.…”

“…Electromagnetic field is analyzed by 3D FEM computation applying Comsol Multiphysics software package, version 3.5. It should be noted that the calculation of the force between the center pole and the yoke of the electromagnet is quite difficult problem [1] due to the presence of two small air gaps where the forces are in opposite directions. The 3D model is shown in Fig.1.…”

FINITE ELEMENT ANALYSIS OF DISPROPORTIONATE REGIONS Rumena Stancheva Ilona IatchevaTechnical University of Sofia ABSTRACTThe paper concerns the detailed electromagnetic field calculation in geometrically disproportionate small regions. For example they could be presented by cracks, small air gaps or inhomogeneous inclusions. Unfortunately each of them is possible to be a part of investigated device. In the electrotechnic this is very often encountered problem. The task is interesting in computational aspect mostly as the field values, forces or pressures at this problem region are of important meaning for normal functioning of the device. The similar solution by finite element method would lead either to disproportional dimensions of elements or to huge number of elements. Then the difficulties which have to be overcome are vastly increasing errors or limitations in the computers memory. This impedes the solution of the forward, as well as the coupled and inverse problems in the device. The correct solution is proposed by iteration procedure.

Ab#tract--Tao ways of secondary field quantities and force calculation are dimcussed and compared. For the magnetostatic case both approaches, scalar potentid and vector potential method can be applied. The malar potential formulations have proved to be very effective and finally the normal components of the magnetic flux density can be computed. If the vector potential method i s used, it i s necessary to determine the tangential components of the magnetic field strength as the secondary field value. The paper describes the method of the calculation of 3 D static fields using finite difference solutions. For calculation of forces the Maxwell stress is used.

Investigation of a model to verify software for 3-D static force calculation

Abstract: -Requirements for a model to verify software for 3-D static force calculation are examined, and a 3-D model for static force calculation is proposed. Some factors affecting the analysis and experiments are investigated in order to obtain accurate and reproducible results.
