摘要： An arrangement of a low air inlet and a circuit for driving a torque generator in an ultra-compact centrifugal fan is disclosed. In the ultra-compact centrifugal fan, a region occupied by the circuit is not completely arranged radially inside a cup-shaped portion to which an impeller is attached. At least a part of the low air inlet provided on a bottom of a housing of the centrifugal fan is arranged in a range of predetermined angle in an imaginary ring-shaped portion surrounding a base portion covered by the cup-shaped portion. A part of the circuit, that is not covered by the cup-shaped portion, is arranged upstream of the range of the predetermined angle in a flowing direction of airflow.

摘要： In manufacturing of the stator unit 2 according to one preferred embodiment of the present invention, a plurality of terminal pins are arranged in an axially spaced manner from a plurality of the coils during a twining process of the wires from the coils 232 to the terminal pins 241. Then, after the wire is twined to the terminal pins, the terminal pins connected to the coils are moved along the outer side face of the sleeve housing, functioning to as a guide portion for the terminal pins. By virtue of the configuration, the terminal pins 241 may be approximated to the coils without applying the tension on wire, and the stator unit may be made thin with preventing the open circuit of the wires.

摘要： Slim-profile centrifugal fan made up of a housing, a motor component, and a airflow-generating component. A disk portion, a cylindrical portion, a plurality of posts, and a plurality of blades compose the airflow-generating component. The plurality of posts project from, and are arranged at a predetermined circumferential spacing along, the outer circumferential surface of the cylindrical portion; and each of the plurality of blades is provided on a respective one of the posts. The posts are of sufficiently greater thickness than the blades. Accordingly, air spaces are formed in between the posts and the blades, yet the blades are retained firmly on the cylindrical portion by the posts.

摘要： A tiny-diameter, lengthwise extensive impeller utilized in an ultra-small centrifugal fan is molded by an injection molding operation. In order to avert difficulties attendant on injection-molding ultra-miniature parts, the thickness and length of a reinforcing ring on the tip of the impeller are set to within predetermined ranges. Further, the thickness of each of the vanes that constitute the impeller is made maximum where they join to the impeller ring section.

摘要： A centrifugal fan comprises an impeller, a motor which is connected and rotates the impeller and a housing which has an intake and an air blowing port for housing the impeller. The impeller has a plurality of blades arranged on a circumference. The intake opens opposed to the right end (in FIG.1) of the impeller. The air blowing port opens opposed to a side of the impeller. A gap enlarged portion, in which the distance between the outer circumference of the impeller and the inner face of the housing starts to increase at a point where the distance between the outer circumferential of the impeller and the surface of a nose portion is smallest therein, the nose portion being a region of the vicinity of an edge portion of the air blowing port, the edge portion being the closest side to the outer circumference of the impeller.
