Abstract

An axial-air-gap motor integrally configured by resin molding, a plurality of stator cores being arranged in an annular configuration, wherein the resin is spread in an efficient manner. An axial-air-gap motor, provided with: a plurality of stator cores, a stator, and one or more rotors. The stator cores are provided with a teeth iron core having the shape of an approximate trapezoidal cylinder, a bobbin covering at least the vicinity of both end parts of the outer periphery of the teeth iron core, flange parts provided in the vicinity of the portions of the bobbin that cover the both end parts of the outer periphery of the teeth iron core so as to extend for a predetermined length in a direction perpendicular to the outer periphery of the teeth iron core, and at least one protrusion further extending from the tip of the flange part in the direction of extension. The extension-direction tip of each of the protrusions is brought into contact, in the direction of rotation of an output shaft, with the extension-direction end part of the flange part of another stator core, the stator cores being arranged in an annular shape about the axial direction of the output shaft. The stator cores are integrally molded using a resin to form the stator. The one or more rotors are in a planar-faced configuration with the side surfaces of the end part of the teeth iron core, interposed by a predetermined air gap.
