    摘要: A rotor structure for a permanent-magnet motor is disclosed as including an annular laminated stack (2) of electromagnetic steel sheets incorporating magnets, annular end plates (1a, 1b) located at both ends of the annular laminated stack to hold the same, a cylindrical core buck (3) carrying thereon the annular laminated stack and the annular end plates, and a rotor shaft (5) integrally connected to the cylindrical core buck for rotating movement. The annular laminated stack has a plurality of first fixing portions (8a, 8a′, 8a″; 8b, 8b′, 8b″), and each of the annular end plates has a plurality of second fixing portions (7a, 7a′, 7a″; 7b, 7b′, 7b″) which are held in engagement with the first fixing portions of the annular laminated stack, with the annular end plates and the annular laminated stack being fixed to one another by caulking at the first and second fixing portions.

    摘要: An anisotropic exchange spring magnet powder complexing a hard magnetic material and a soft magnetic material, wherein a rare earth metal element, a transition metal element, boron and carbon and the like are contained, and the hard magnetic material and soft magnetic material have crystal particle diameters of 150 nm or less. A method of producing an anisotropic exchange spring magnet powder comprises treating a crystalline mother material containing a hard magnetic material and soft magnetic material or the crystalline mother material having amorphous parts, in a continuous process composed of an amorphising process and the following crystallizing process, repeated once or more times. An anisotropic exchange spring magnet is obtained by treatment, in an anisotropy-imparting molding process and a solidification process, of an anisotropic exchange spring magnet powder.
