Abstract
Abstract
The high requirements for magnetic circuits used in electrical equipment particularly concern the possibility of reducing energy losses. In the presented paper, the influence of the material structure on the formalism of the energy losses model is considered. It has been shown that the structure has a significant effect on the dependence between the number of magnetic domains involved in the material demagnetization and the excess magnetic field. This dependence is the basic concept of the considered model. The results presented in the paper can be used for prediction of losses in magnetic materials of different structures with satisfactory predictive errors at the design stage of magnetic circuits by means of CAD tools.
