Measurement and Modeling of$B$–$H$Loops and Losses of High Silicon Nonoriented Steels

On physical aspects of the Jiles-Atherton hysteresis models

“…4(a), dynamic loops predicted by the DHM-B are a good first approximation of those obtained experimentally (a method 22,23 of improving the DHM-B will be mentioned at the end of this section). On the contrary, the dynamic loops in Fig.…”

“…Under these conditions, the loss separation (8) is equivalent to the field separation 22,23 HðtÞ ¼ H hyst ðtÞ þ H clas ðtÞ þ H exc ðtÞ;…”

Comparison of engineering methods of loss prediction in thin ferromagnetic laminations

“…The first material, Steel-0.1, is 0.1 mm thick, 5.5% Si, r ¼ 0.735 mO m, while the other, Steel-0.5, is 0.5 mm thick, 1.8% Si, r ¼ 0.432 mO m. It was shown in Ref. [8] that the TSM applied to high silicon Steel-0.1 provides the same accurate prediction of the dynamic loops and losses (up to 1 kHz and B m ¼ 1.3 T) as the MDM [1]. The measured loss dependence shown in Fig.…”

“…A convenient tool to include excess loss in the total loss evaluation is the thin sheet model (TSM) [8], which enables the total loss (W ¼ W h +W clas +W exc ) to be calculated as:…”

“…(8) and (9) is caused by the necessity to compensate for the absence of the excess loss term in these formulae. It is considered that the value of k chosen for the sinusoidal regime through Eq.…”
