High hysteresis loss
WebHysteresis Loss, Resistivity, p, (core loss) The enclosed area within the hysteresis, shown in Figure 2-1, is a measure of the energy lost in the core material during that cycle. This loss is made up in two components: (1) the hysteresis loss and (2) eddy current loss. The hysteresis loss is the energy loss when the magnetic material is going ... Web23 de fev. de 2024 · W h = η × B m 1.6 × f × V. Where η is Steinmetz constant or hysteresis coefficient. f is frequency. B m is the magnetic flux density. V is the volume of the core. W h is hysteresis loss. ∴ The hysteresis loss in a given magnetic material may be decreased by decreasing maximum flux density established through it or by using …
