  • Publication number: 20180219440
    Abstract: To provide an outer rotor type motor including a rotor magnet capable of reducing a cogging torque for realizing smooth rotation of a rotor and having good durability and weatherability. A rotor magnet is arranged so as to be divided into plural segment magnets on an inner peripheral surface of a rotor yoke in a circumferential direction, an anisotropic magnet having parallel orientation is used as each segment magnet and a central portion of a magnetic-flux generation surface facing a magnetic-flux action surface of a stator pole tooth is formed in a convex surface where an interval with respect to the stator pole tooth is the smallest.
