Research on Loss Property Simulation of Non-oriented Steel Sheets

The accurate simulation of the loss characteristics of magnetic materials is of great significance for improving the efficiency and performance of electrical equipment, and has attracted extensive attention from scholars at home and abroad. Based on the classical Steinmetz empirical formula, an improved loss calculation model is proposed. The model considers the relationship between frequency and loss and sets the calculated parameters of the loss model as a function of frequency. Then the model is applied to simulate the loss property of non-oriented silicon steel sheets under different excitation frequencies. The simulation results are compared with the experimental results, and the validity of the model is verified, which provides a theoretical basis for the accurate simulation of the loss of non-oriented silicon steel sheets.
