Abstract :
Models taking into account the anisotropy and nonlinearity of doubly oriented, grain oriented and nonoriented electrical sheets, were implemented in finite element CAD software. These models based on the coenergy density have been used to model different electrical power devices and to compare their performance. The doubly oriented sheets proved to be more suitable than the conventional soft magnetic materials. The power devices modelled were: a large generator, a small synchronous motor, a T-joint of three-phase power transformer, and a small punched transformer
