Predicting Loss in Magnetic Steels Under Arbitrary Induction Waveform and With Minor Hysteresis Loops
IEEE transactions on magnetics
We have studied ways of predicting power losses in soft magnetic laminations for generic time dependence of the periodic magnetic polarization ( ). We found that, whatever the frequency and the induction waveform, the loss behavior can be quantitatively assessed within the theoretical framework of the statistical loss model. The prediction requires a limited set of preemptive experimental data, depending on whether or not the arbitrary ( ) waveform is endowed with local slope inversions (i.e.,doi:10.1109/tmag.2004.830510 fatcat:f4z43qdjbfhwnfawgchnq5h3n4
