Abstract

This paper presents and discusses some numerical approaches for the simulation of induction machine behaviour under no-load conditions. All the approaches are based on the finite element solution of the electromagnetic field problem, including physical models of magnetic material and interaction with external circuits. The computed flux distributions enable the prediction of magnetic and additional losses, whose accuracy is discussed also in the light of the complexity of the used numerical technique.
