Abstract:
A motor device comprising:a base; a bearing unit fixed on the base; a core unit including cores which extend from the bearing unit along an upper face of the base and coils provided around the cores; a rotational shaft comprising two ends, of which one end is rotatably supported by the bearing unit; a rotor fixed to the other end of the rotational shaft; and a magnet fixed to the rotor and opposing the core unit, further comprising a positioning member fixed on the base for positioning the core unit on the base, and a supporting member formed integrally with the positioning member and extending along the upper face of the base, wherein the bearing unit includes a shaft supporter having a cylindrical shape which rotatably supports the rotational shaft, and a flange having a concavity, the flange extending from the shaft supporter along the and having an approximately uniform thickness, wherein an upper surface of the supporting member is formed at a position higher than an upper surface of the flange with respect to the upper face of the base, the supporting member is placed on a bottom surface of the concavity and is supported by the flange, and wherein the core unit is supported by the upper surface of the flange and the upper surface of the supporting member in a manner inclined with respect to the upper face of the base by being placed on the upper surface of the flange and the upper surface of the supporting member.
