Abstract: A fan assembly having a reduced dimension formed by several modifications is described. The fan assembly includes a stator having stator coils positioned within a recessed portion of a pillow that receives the motor. The stator may include wire connections positioned between adjacent stator coils and designed to terminate wires of the stator coils. The wire terminations may be on a protrusion or a post positioned between adjacent stator coils, or alternatively, the wire terminations may be disposed on protruding features of a bushing. The protrusion may be formed from an electrically conductive material and electrically connected to a motor control circuit via a flexible printed circuit. In some embodiments, the protrusion is part of an electrically neutral stator bushing having several pins. Also, a gap region between the bushing and a flange feature is designed to improve an adhesive joint.

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.

Abstract: A linear motor heat dissipation structure including multiple teeth arranged linearly at predetermined intervals each with coil wound around rectangular tube-shaped bobbin, and heat dissipation member provided between adjacent coils that dissipates heat generated coils by transmitting the heat to an external section. Heat dissipation member is sandwiched by bowed sections of coils that are curved outwards within edges of rectangular tube-shaped bobbin due to elastic force of coils. Accordingly, even when there are component tolerances and assembly tolerances, those tolerances are absorbed by the elastic deformation of the bowed section of coils such that the variance in the contact state between coil and heat dissipation member is made smaller so that stable and high heat dissipation performance is achieved.
