PROCESS FOR PRODUCING FLEXIBLE HYBRID RARE EARTH BONDED MAGNET, MAGNET AND MOTOR

PROBLEM TO BE SOLVED : To provide a material exhibiting (BH)max higher than that of a magnetically isotropic bonded magnet by fixing an Nd2Fe14B based aggregated polycrystalline rare earth magnet powder of pulverized melt span ribbon with resin. SOLUTION : A compound precursor forming a cell of single domain particle rare earth magnet powder through a medium of binder component using a magnetically anisotropic aggregated polycrystalline rare earth magnet powder as a core substance is prepared, and a compound comprising the precursor, a powdery thermosetting polymer compound and the binder is compacted while applying an orienting magnetic field in the plasticizing temperature region of the powdery thermosetting polymer compound. A green compact can be made while suppressing mutual mechanical damage of the core substance of compound precursor, i.e. the aggregated polycrystalline rare earth magnet powder, by the compression stress distributing action of the precursor cell or the buffering action of the powdery thermosetting polymer compound through plastic deformation.
