发明名称 SOFT MAGNETIC GREEN COMPACT, PRODUCTION METHOD THEREFOR AND MOTOR
摘要 <P>PROBLEM TO BE SOLVED: To provide a soft magnetic green compact having a high bending strength by suppressing increase in iron loss, and to provide a manufacturing method therefor and a motor using the soft magnetic green compact. <P>SOLUTION: In the surface of a soft magnetic green compact of iron alloy powder containing iron powder or iron as a main component, an oxidation phase mainly composed of iron is formed on the individual iron powder surfaces, an oxidation influence layer of 0.4-1.4 mm thick containing an iron oxidation phase and an inorganic insulator is formed on the iron powder interface, and the soft magnetic green compact in the oxidation influence layer is in non-oxidation state. A manufacturing method therefor, and a motor using the soft magnetic green compact are also provided. <P>COPYRIGHT: (C)2013,JPO&INPIT
