SOFT MAGNETIC MEMBER, LAMINATED BODY OF SOFT MAGNETIC MEMBERS, AND MANUFACTURING METHOD FOR THOSE MATERIALS

摘要

PROBLEM TO BE SOLVED: To provide a soft magnetic member which is excellent in practical utility as a soft magnetic member by achieving much lower eddy current loss compared with a conventional soft magnetic member made of a laminated electromagnetic steel plate at much lower cost than a conventional pressed powder core, as well as to provide a laminated body of the soft magnetic members and a manufacturing method for those materials. SOLUTION: A plate-like soft magnetic member 3 is composed in such a manner that many soft magnetic strips 2 are disposed to extend in the right-angled direction to its plate thickness direction and an opposing surface of each of the soft magnetic strips 2 is electrically isolated by an insulating film followed by bonding. This allows to configure the low-cost soft magnetic member with reduced eddy current loss. COPYRIGHT: (C)2008,JPO&INPIT
