Satisfactory FeCo soft magnetic material and soft magnetic electric subassembly null of soft

摘要

PURPOSE:To improve characteristics of Fe-Co soft magnetic material having very high saturation magnetic flux density. CONSTITUTION:The title Fe-Co soft magnetic material has very high saturation magnetic flux density, but its soft magnetic characteristics is not so high. The soft magnetic property of the material is remarkably improved by adding tensile force. By applying this information to technical development, an assembled body of an Fe-Co soft magnetic material, having excellent soft magnetic property, and a soft magnetic electric part is accomplished using the method in which a tensile film is formed on the surface of a steel plate, a toroidal coil is formed in a tensile-stress applied toroidal coil and face-pressure is applied. As a result, the Fe-Co soft magnetic material and soft magnetic electric part assembled body, having very high magnetic flux density and excellent soft magnetic characteristics, cafe obtained.
