Abstract
PURPOSE:To uniformize surface magnetic flux density along the longitudinal direction of a pole face by disposing a gate port at the time of molding an anisotropic resin magnet which forms substantially a sector or rectangular- shaped sectional rod-like molding having a face with a pole in a circular-arc shape, at the longitudinal end of the molding. CONSTITUTION:When the width of circular-arc-shaped face of a gate port 11 along its chord 12 is X and the width perpendicular to the chord is Y, X/Y>=1 is set. An anisotropic resin magnet in which magnetic particles are so oriented as to direct toward both side faces 13 crossing the circular-arc-shaped face 10 from the face 10 becoming a pole face, a first pole (e.g., N-pole) is magnetized on the face 10 and a second pole (e.g., S-pole) is magnetized on both side faces, is molded in a magnetic field in an injection metal mold. That is, the port 11 is disposed at the longitudinal end of a molding cavity, mixture of fluidized resin and magnetic particles is poured through a gate and a runner, the mixture is molded and solidified in the magnetic field by a yoke, thereby obtaining the anisotropic resin magnet.
