Claims

[Claims for Utility Model Registration] (1) A stator comprising a coil that generates a rotating magnetic field, a yoke for the stator having an outer peripheral upright portion, a bearing, and a base made of resin, and a stator rotatably supported by the bearing. A motor structure comprising a rotor comprising a spindle, a driving permanent magnet attracted by a rotating magnetic field of the coil, and a resin main body comprising a rotor yoke having an outer peripheral upright part, A motor structure characterized in that at least one of the stator and yoke of the stator, and the rotor and the rotor yoke are integrally molded with resin. (2) The motor structure according to claim 1, characterized in that the main body of the rotor is provided with a plurality of blades to form a fan motor. (3) The yoke for the rotor is formed into a disk shape having an inner circumferential rising part and an outer circumferential rising part, and the driving permanent magnet is provided to be guided with respect to the inner circumferential rising part, while the outer circumferential rising part A motor structure characterized in that the motor is integrally molded with the main body.
