Magnetization energy loss of electrical steel sheets with goss texture

Design of electrical machines and transformers requires use of adequate model of energy loss in magnetic cores. Classical core loss models were elaborated more than one century ago and for materials produced at that time. Since then modern electrical steel sheets with very low specific power loss were developed. For modern materials were developed also modern power loss model. One, most popular is the statistical loss model which was subject to improvement for many years. The model is worth to mention and farther development because it parameters posses physical meaning. The paper presents flux density and frequency behavior of statistical loss models parameters in grain and non-oriented electrical steel sheets.
