<p>Accurately calculating magnetic loss under direct current (DC) bias conditions remains challenging, particularly when relying solely on manufacturer-provided data. To overcome the limitations of existing prediction models, which depend heavily on experimental measurements under DC bias, this study proposes a calculation method for magnetic loss in electrical steel based on the elliptic loss model. First, a correction coefficient for magnetic field strength is introduced into the classical elliptic loss model to develop a static hysteresis loss prediction model that incorporates the influence of field strength. Second, the static hysteresis loop under DC bias is divided into upper and lower half-branches, and corresponding static hysteresis loss models are established for each branch. This approach enables the formulation of a static hysteresis loss prediction method under DC bias. Finally, by applying statistical loss theory, a comprehensive magnetic loss prediction model is constructed that accounts for both magnetization frequency and DC bias effects on eddy current and excess losses. The accuracy and applicability of the proposed model are validated by comparing experimental measurements with simulation results.</p>
