Abstract :
This paper presents the calculation of the induced currents and forces for a 3D nonlinear eddy current field problem with ferromagnetic moving conductors. The A&oarr;, V-A&oarr; formulation is used in combination with four different gauging methods to stabilize the solution process. To consider nonrectangular shapes of geometries tetrahedral elements were employed. The computation procedure is applied to a hybrid magnetic levitation system of a contactless and frictionless conveyance system
