English abstract:
In most applications, eddy current losses in ferromagnetic material
are generated in a rather thin layer immediately at the surface. The
thickness of the saturated layer is limited to a few millimeters,
otherwise the losses would cause excessive heat. A novel material
formulation with some simplifications regarding the nonlinear magnetic
characteristic within the finite element analyses represents the actual behaviour quite accurate. The utilized surface elements deal with the fundamental harmonic of flux density and current density, respectively.
Thus, it is possible to represent the mutual influence of flux and eddy currents for complex geometries including ferromagnetic material in a very efficient way.
