摘要
In this paper, four different grades of fully finished, non-oriented (NO) electrical steels, i.e., M530-50A, M400-50A, M350-50A, and M290-50A, were selected. Their measured magnetic properties were the basis for the derived and validated magnetic-loss prediction model. Based on the experimental data and the modified Steinmetz equation, a simplified predictive model valid at temperatures up to 230 °C, in the frequency range 30-2000 Hz, and magnetic flux densities up to 1.0 T, is proposed. The model's prediction coefficients are proposed for the eddy current, hysteresis, and excess loss components. An empirical equation for predicting the magnetic losses, valid up to 1.0 T, highlighting the changes in the magnetic losses with temperature is derived. The equation leads to excellent agreement between the measured and predicted magnetic losses for four grades of NO electrical steel.
