摘要： A motor includes a cover made of a resin material. The cover includes a first annular portion arranged to extend in an annular shape above coils, a side wall portion arranged to extend downward from an outer circumferential portion of the first annular portion, and a second annular portion arranged to extend radially outward or radially inward from a lower end portion of the side wall portion along an upper surface of a circuit board. The side wall portion is arranged to extend in an axial direction while filling in gaps between teeth on a radially inner side of radially outer end surfaces of the teeth. The coils are covered by the cover to be protected from dust, water droplets, etc. The radially outer end surfaces of the teeth are exposed from the cover, and are thus arranged to be in radial proximity to a rotor magnet.

摘要： An axial flow fan includes a housing that is formed by a process including injection molding includes a tapered surface at a frame portion thereof. One end of at least one rib is connected to an attachment portion which is a part of a stator portion of a motor portion, and the other end the rib is connected to a base portion protruding from the tapered surface. Two inclined surfaces connected to the tapered surface at the base portion and arranged in a circumferential direction with respect to a central axis are inclined such that the further a portion of the inclined surface from the central axis is, the further the portion is from a center of the rib. As a result, an air flow disturbance generated by the base portion between the rib and the frame portion is minimized, thereby reducing a noise generated due to the air flow disturbance.

摘要： A fan for generating an air flow by rotating an impeller with a motor is provided. A cylindrical outer side surface of a rotor of the motor is press-fitted to an inner side surface of the impeller cup which is substantially cylindrical. An outer side surface of the impeller cup is a portion of a circular conical surface, thereby increasing the amount of air generated and transmitted by the fan. A gap is formed between the outer side surface and the inner cylindrical surface of the impeller cup. The cylindrical outer side surface of the rotor is connected to the inside of the inner cylindrical surface of the impeller cup coaxially with each other. Thus, the impeller and the rotor can be reliably fixed to each other with improved performance of transmitting air.
