Dependence of the power losses of a non-oriented 3% Si-steel on frequency and gauge

Comparison of engineering methods of loss prediction in thin ferromagnetic laminations

“…These formulae and corresponding loss curves (12) and (13) are given in Fig. 3, which confirms the advantage of using loss factor L f instead of FFC F c in the case of minor loops.…”

“…The inadequacy of such loss separation was pointed out previously [12]. Its artificial nature is also illustrated in Fig.…”

“…3 is that twocomponent formula (13) produces the loss curve, which is closer to the reference curve MDM than that calculated by Eq. (12). The inferior result obtained through Eq.…”

Characterization of electrical steel grades for direct application to electrical machine design tools

“…It has been shown that Eq. (1) is only valid for up to 120 Hz for 0.50 mm thick strip [5] and for proper accuracy the loss coefficients should be a varying parameter of at least flux density. However, computation of losses from Eq.…”

“…Other results are provided in Ref. [5]. It can be seen that the laser cutting has in general, higher losses than those for guillotine cut strips.…”
