Modelling the electromagnetic behaviour of SiFe alloys using the Preisach theory and the principle of loss seperation (Q5947085)

Summary: We present two simplified methods for the evaluation of magnetization loops in laminated SiFe alloys, using the Preisach theory and the statistical loss theory. These methods are investigated in detail as a practical alternative for a very accurate, but much involved numerical approach, viz. a combined lamination model -- dynamic Preisach model earlier developed by the authors. Particularly, one of the two methods provides accurate results inspite of a dramatic reduction of the CPU-time in comparison with the earlier developed combined model. For the other simplified method, the reduction of CPU-time is less pronounced but still considerable and the results are fairly good.
