摘要：

The validity of the Steinmetz law, describing the total energy losses as a function of maximum induction from 0.1 to 1.2 T has been verified in the frequency range from 100 Hz to 1.2 kHz for iron-based soft magnetic composites (SMCs), with the aim to determine the coefficients in Steinmetz law. The Bertotti's statistical model was used to modify the Steinmetz law, for the hysteresis energy loss Wdc of SMCs magnetized in dc magnetic field, to the model for total energy losses Wt when an ac magnetic field is applied. In this case the total energy lossesWt consist of hysteresis losses to which the dynamic energy lossesWd, consisting of interparticle eddy current lossesWc int er, intraparticle eddy current lossesWc int raand excess lossesWe, were added. The validity of this model was experimentally proven for the investigated Fe-based SMCs at maximum inductions Bm ranging from 0.1 to 1.2 T.
