The paper deals with the calculation of hysteresis power loss in cores of electromechanical converters. The analysis was carried out using the Jiles-Atherton model of ferromagnetic hysteresis incorporated into two-dimensional time-stepping finite element model. A vector hysteresis model was constructed by the vectorisation of a scalar model. The total power loss due to hysteresis was split into two component, one originating from the purely alternating magnetic field, and the second being a consequence of the local predomination of vector nature of magnetic field distribution. Two computational examples are presented showing the general applicability of the algorithm for determination of power loss distribution.

W pracy przedstawiono wyniki obliczeń strat mocy z histerezy w rdzeniach przetworników elektromagnetycznych. W analizie zastosowano dwuwymiarowy model obwodowo-polowy skonstruowany na bazie metody elementów skończonych oraz model histerezy. Wektorowy model histerezy magnetycznej skonstruowano metodą wektoryzacji modelu skalarnego Jilesa-Athertona. Dokonano rozdzielenia całkowitych straty mocy z histerezy na straty będące wynikiem składowej przemiennej rozkładu przestrzennego pola magnetycznego oraz straty wynikające z obrotu wektora indukcji magnetycznej w lokalnym układzie współrzędnych. Przedstawiono dwa przykłady obliczeniowe ilustrujące możliwości zastosowania opracowanego algorytmu.
