Abstract: The standard Newton iteration scheme to solve a non-linear system of equations obtained from the finite element methods is based on the updating of thp field dependent element reluctivity. Usually, the manufacturer of the ferromagnetic material provides a BH-characteristic as diagram or in the form gf a table of data samples. The influence of the material properties, in particular their accurate numerical representation, is significant for the rate of convergence during the Newton iterations Here, a numerical optimization aiming at a technically smooth nonlinear characteristic is performed to obtain a higher rate of convergence of the Newton iteration scheme.
