Analytical inverse model with flexible parameters for dynamic hysteresis loops modelling

摘要

Zaproponowano inwersyjny model analityczny do opisu matematycznego dynamicznej pętli histerezy materiałów magnetycznie miękkich. Model był sprawdzony dla próbki otwartej klasycznej blachy elektrotechnicznej przy sinusoidalnym magnesowaniu.%Analytical inverse model was proposed to find simple mathematical approximation of dynamic hysteresis loops of soft magnetic materials. It consists of dynamic loop construction from three components by means of mathematical functions. Favourable mimicking coefficients were searched, which depend on excitation amplitude and frequency. The nature of its behaviour was studied in order to be able to predict the loop shape. The model was tested for opened specimen of classic silicon electrical steel at sinusoidal excitation, measured by compensation ferrometer.
