The factors influencing the magnetic losses in silicon steel under varying frequencies include the hysteresis loss, eddy current loss, and excess loss. Hysteresis loss is caused by the magnetization and demagnetization process of the material, which leads to energy dissipation. Eddy current loss occurs due to the induced currents circulating within the material, resulting in resistive heating. Excess loss is mainly caused by the non-uniform distribution of magnetic domains within the steel, leading to localized energy losses. These factors are influenced by the frequency of the applied magnetic field, as higher frequencies increase the eddy current losses and excess losses while hysteresis losses remain relatively constant.
