Anisotropic properties of electrical steels

Anisotropy is an important phenomenon, which should be taken into account by the designers of magnetic circuits in electrical machines. Even the so-called non-oriented (dynamo) steels feature significant anisotropy. It is thus essential to work out new analytical methods and mathematical models, which may be easily implemented in CAD routines. The paper describes one of possible approaches to address the problem. The results of model prediction are compared to available measurement data for chosen grades of non-oriented and grain-oriented steels.
