  • Device for producing annular or arcuate magnet
    Patent number: 7367791
    Abstract: A device capable of producing an annular magnet or arcuate magnet with excellent dimensional accuracy and magnet performance, of which the mass is not greatly scattered. The device for producing the annular magnet, for example, includes a preforming section for obtaining an annular preformed body from a compound of a mixture of an anisotropic magnet powder and a thermosetting resin, a magnetic field orienting and forming section for obtaining an annular intermediate formed body by subjecting the annular preformed body to orienting and pressure-forming, a main forming section for obtaining an annular magnet by further forming the annular intermediate formed body, and a work transferring section for transferring works.
    Type: Grant
    Filed: November 19, 2004
    Date of Patent: May 6, 2008
    Assignee: Aichi Steel Corporation
    Inventors: Tetsu Murata, Ryoji Makino, Yuji Takemoto, Katsuyuki Hiraiwa, Shinji Kawamura, Takahiro Nishiyama, Yoshinobu Honkura, Hironari Mitarai, Kenji Noguchi
