THE INFLUENCE OF TEXTURE ON POWER LOSSES IN NONORIENTED ELECTRICAL STEELS

The power losses in nonoriented electrical steels are affected by both the crystallographic orientation of the grains (texture) and grain si ze, a parameter not related to texture. In this article, a model is pr oposed which allows the separation of the textural and nontextural con tributions to power losses in these materials. The influence of textur e on power losses is associated with the appearance of the perpendicul ar component of magnetization which is a consequence of the presence o f magnetic domain structure.
