An improved approach to power losses in magnetic laminations under nonsinusoidal induction waveform
Abstract
It is shown that it is possible to accurately predict power losses in ferromagnetic laminations under nonsinusoidal magnetic flux by specifically considering the dependence of hysteresis, classical, and excess loss components (P/sub h/, P/sub c/, and P/sub e/, respectively) on the magnetic induction derivative B. Basically, it is assumed, through generalization of experimental and theoretical results under sinusoidal induction, that P/sub h/ is proportional to the average value of the instantaneous induction derivative, P/sub c/ is proportional to the average value of the square of the instantaneous induction derivative, and P/sub e/ is proportional to the average value of the instantaneous induction derivative to the three-halves power. An analytical expression for total power losses under distorted flux is consequently worked out. Experiments are reported concerning grain-oriented, nonoriented, and amorphous laminations, with distortion introduced by a variable amount of the third harmonic flux component.>

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
