Resumen de Three dimensional magnetic field analysis in a linear motor by means of scalar potential
The field of magnetic levitation by ferromagnetic attraction in conjunction with a linear propulsion system has experienced interest for many years. The increasing capacity of modern computers allow the use of numerical field calculation methods under very realistic conditions. This paper deals with possibilities of a scalar potential magnetic field analysis in a short‐stator propulsion system. The eddy currents in the railway were modelled by the special boundary condition for a thin sheet. The numerical algorithm is based on a finite element method with tetrahedrons. To increase the accuracy of calculations the adaptive technique was introduced. As results the calculated forces, power losses in the railway and the adaptive meshes were shown.
