Abstract
The authors give a detailed analysis of the space and time distribution of the field variables B, H, and E inside saturating laminations, using a harmonic domain modeling method. A simple way has been devised for the representation of hysteresis. It was found that hysteresis affects to a small degree the variation of H and B but has no noticeable influence on E and thus, as expected, does not interact with the corresponding eddy current losses. It is shown that saturation distorts the linear space distribution of the eddy currents but that the assumption of linear distribution still leads to a very simple method for eddy current loss calculation which is remarkably accurate at 60 Hz. >
