Abstract:
A brushless motor having a resin bearing comprising:a rotor including a rotor case having opposed outside and inside surfaces and a support protruding from the outside surface and including an opening in the rotor case; an output transfer device integral with the support and disposed partially within the opening, at a first side of the rotor case; and a magnet disposed at a second side of the rotor case; a shaft supporting the rotor; a resin bearing supporting the shaft for rotating and having an oil-containing portion; a generally planar stator base having opposed inside and outside surfaces, a hole, and a bearing support oblique to the first surface and embedded in the resin bearing; a bridge, wherein the resin bearing is upstanding from the inside surface of the stator base and is reinforced by the bearing support and the bridge, the bridge being incorporated in a part of the resin bearing opposite the shaft that protrudes from the hole and the outside surface of the stator base; and a stator for driving the rotor, the stator being located at the inside surface of the stator base, farther from the shaft than the resin bearing.
