Abstract
This paper deals with the fundamental theoretical background of a 1-D parametric magneto-dynamic (PMD) model, which analytically solves the interdependence of the magnetic field and macroscopic eddy currents inside a thin soft magnetic steel sheet (SMSS). Furthermore, the loss calculation using the discussed model is presented, where instantaneous powers due to static hysteresis and induced eddy currents, as well as their power loss distributions across the SMSS thickness are calculated. The calculated results are validated by measurements on a non-oriented SMSS using sinusoidal excitations within wide frequency and magnetic flux density ranges.
