    Abstract: Provided are molds for polar anisotropic ring-shaped bonded magnet molded articles which enable the production of bonded magnet molded articles with a high degree of roundness and only slight distortion, without the need for mold modification and preparation of a test mold, and a method of preparing such molds. The present invention relates to a method of preparing a mold for a polar anisotropic ring-shaped bonded magnet molded article, the method including: 1) determining the shrinkage length (Tc) of a desired polar anisotropic ring-shaped bonded magnet molded article using the following equation: Tc=T×(α1/100−α2/100); 2) determining the radius (Dm) of a magnetic pole portion of a mold cavity using the following equation: Dm=D/(1−α2/100); and 3) defining the outer peripheral shape of the mold cavity from the Tc, the Dm, and the number (P) of magnetic poles of the molded article.

    Abstract: A bonded magnet is provided which includes first and second components. The first and second components have first and second non-action surfaces, and first and second action surfaces that intersect the first and second non-action surfaces, respectively. First and second flux groups curve inside the first and second components from the first and second non-action surfaces to the first and second action surfaces, respectively. The areas of the first and second non-action surfaces are greater than the first and second action surfaces, respectively. The flux densities on the first and second action surfaces are higher than the first and second non-action surfaces, respectively. The pole on the first non-action surface is opposite to the second non-action surface. The first and second non-action surfaces are coupled to each other. The first flux groups continuously extend from one to another.

    Abstract: A method for manufacturing a bond magnet includes providing a bond magnet composition including a magnetic material and a resin, extruding the bond magnet composition in one direction to produce a molded body while orienting the magnetic material in the one direction, magnetizing the molded body in the one direction using an axial magnetization to produce a magnetized molded body, and laminating the magnetized molded body to produce a laminated molded body including first magnetized molded layers and second magnetized molded layers. The first magnetized molded layers and the second magnetized molded layers are alternately laminated. A first magnetization direction of each of the first magnetized molded layers is opposite to a second magnetization direction of each of the second magnetized molded layers.
