Abstract

This paper deals with the direct inclusion of vector hysteresis and eddy current losses in a 2D finite element (FE) time stepping analysis. It is shown that a vector Preisach model can be inverted in an efficient way by means of the Newton-Raphson method and that it thus can easily be included In the Newton-Raphson iterations of the FE equations. The eddy current losses are accounted for by considering an additional conductivity matrix in the FE equations. The method is applied to the no load simulation of an induction motor. The calculation results are discussed and compared to measurements
