Abstract

The using in alternating current of materials for electromagnetic circuits requires them high inductions and low dynamic (eddy-current) losses. These are strongly influenced by the work frequency and induction, and also by the magnitude of density and electrical resistivity of materials. The traditional solution is using of electrical laminated steel sheets. In the last years, research and development of composite materials from organic/inorganic insulated iron powders opened new opportunities for design and dimension of magnetic circuits from electrical devices, of 3D magnetic flux circulation concept. This paper will present the influence of processing conditions (insulating layer type, grain size of iron particle, compacting and curing conditions) on the main characteristics of powder systems used in nonconventional soft magnetic circuits..
