PROBLEM TO BE SOLVED : To provide a pole anisotropic compound bond magnet by arranging a rare-earth magnet by selectively filling it into a pole-oriented magnetic pole part to control a high surface magnetic flux density characteristic and corrugated magnetic flux density on the surface of the magnet, not by arranging the rare-earth magnet all over the entire ring circumference as before in order to solve the problem of a conventional technology. SOLUTION : The compound bond magnet is the pole anisotropic compound bond magnet molding having a plurality of magnetic poles on its surface and mainly comprises a ferrite resin composite of the bond magnet molding with the rare-earth magnet arranged at a plurality of magnetic poles on its surface. The rare-earth magnet of the magnetic pole part comprises at least one of an NdFeB system alloy, an SmFeN system alloy, and an SmCo system alloy. COPYRIGHT : (C)2007, JPO&INPIT
