摘要： A surface magnet type rotor and an inner magnet type rotor having good motor characteristics in which bonding strength is high between a magnet section and a soft magnetic yoke section, and structural reliability is high even in high speed use, and its producing method. The rotor comprises an anisotropic bond magnet section and a soft magnetic section wherein the anisotropic bond magnet section is preformed in magnetic field and then formed to be integrated with the soft magnetic section in nonmagnetic field. Subsequently, it is heat hardened to produce a surface magnet type rotor. Magnet units, each having a magnetic pole composed by bonding a pair of permanent magnets such that the directions of magnetization become symmetric with respect to the bonding surface, are linked such that magnetic poles of different polarities appear alternately on the magnetic action surface thus forming an anisotropic magnet body. Good motor characteristics can be attained by setting an angle to 5-40° between the direction of magnetization of the permanent magnet and a diametral direction passing the bonding surface.
