Aspects Regarding the Numerical Computation of the Eddy Current Problem within the Electromagnetic Induction Processes of Thin Planes

Abstract

This paper deals with the numerical simulation of quasi-stationary electromagnetic field in stainless steel thin parts placed into inductive equipment. The applied calculations are performed inthree-dimension (3D) using the finite element method (F.E.M.), which allows an accurate computation of the electric and magnetic field inside the studied part during induction heating. Eddy current density and joule losses are evaluated as a function of amplitudeand frequency of the exciting current in order to determin the required heating time and thermal field field inside the sample.
