Field and temperature calculations in transverse flux inductive heating devices heating nonparamagnetic materials using surface impedance formulations for nonlinear eddy-current problems

This paper presents the calculation of both the field and temperature distribution in thin moving nonparamagnetic sheets in transverse flux inductive heating devices (TFIH). The surface impedance formulation for nonlinear materials is extended to this thin plate problem. The temperature distribution is obtained by solving Fourier´s thermal conduction equation. In this nonlinear coupled electromagneto-thermal problem the temperature dependencies of the B/H curve, the conductivity and the thermal conductivity are fully considered
