摘要
This paper shows that there is very little effect of the silicon content on the hysteresis component of the magnetic losses when two steels with 2.45% and 3.3% silicon were compared. Two non- oriented steels with 2.45 wt% and 3.3 wt% Si have been investigated. The Hysteresis component was measured by two techniques, in an Epstein frame: by a quasi- static test at 5 MHz and by extrapolating the total loss from frequencies above 50 Hz. The results showed that the quasi- static hysteresis loss (5 MHz) is not affected by increased Si content. The method of measurement by extrapolating-from frequencies above 50 Hz-(W*h) proved inaccurate, as it is influenced by the electrical resistivity of the steels.
