Abstract
Epstein-frame loss measurements were performed on 3.2% Si-Fe nonoriented strips cut along and transverse to the rolling direction, in the frequency range 10–100 Hz and at various peak inductions between 0.3 and 1.6 T. The behavior of hysteresis loss Ph and excess loss Pe vs peak induction B and frequency f was worked out and analyzed. The B dependence exhibits a rich structure, as a consequence of the coupling between magnetic domains and the grain structure. The f dependence follows the law Pe∝f3/2, in agreement with previous experiments. These results are interpreted in the frame of a generalized Preisach model recently proposed. It is shown that the excess loss dependence on B is in direct relation with that of the permeability B/H along the virgin magnetization curve. The results of numerical calculations of model predictions are presented and discussed in comparison with experimental data.
