“…This movement occurs even at very low magnetization frequencies. Therefore, firstly, the component has been associated with the hysteresis loss [52][53][54], and it was not until later that it was combined with micro eddy currents created by the domain wall movement. The literature reports on numerous attempts to establish some relationships between the excess loss and the non-uniform distribution of permeability in the sample cross section.…”

Grain-oriented (GO) electrical steel (ES) laminates are still very important in industrial applications due to their remarkable crystallographic properties. Cores of large electrical machines and transformers are built from ES. The performances of these devices are significantly influenced by the properties of ES. The improvement of ES properties has been the subject of considerable research for many years. The phenomenon of magnetic anisotropy is highly non-linear, and it should be taken into account by the designers of magnetic circuits. The article proposes a modified model for calculating the angular properties of specific total loss of ES. The modeling takes into account the isotropic component (from classic eddy currents) and the anisotropic component, which is the sum of hysteresis and excess losses. For the directional loss modeling, the Boltzmann function was used. An analysis of the dependency of model coefficients on the frequency is presented.
