Steinmetz' parameters fitting procedure for the power losses estimation in soft magnetic materials

For different sorts of electrical sheets, the magnetic losses separation using Bertotti method was performed. Using a fitting procedure, the Steinmetz coefficients were approximated. For each parameter, an analytical expression regarding the measured values was determinated. Finally, a comparison between the measured data and the predicted losses was made. The modeled losses are quite close to the experimental one and the modeled might be validated on other sort of sheets.
