摘要： A side wall of a centrifugal fan includes a gap expanding portion arranged to gradually expand a gap between an impeller and the side wall from an upstream end toward a downstream end with respect to a rotation direction of a rotating portion. In the centrifugal fan, an electronic component arranging portion of a board is arranged in an area surrounded by the gap expanding portion, the impeller, and an air outlet, and accordingly does not overlap with a motor or the impeller in an axial direction. The electronic component arranging portion is arranged in an area extending, in a circumferential direction about a central axis, from a position 180 degrees upstream from a middle of the air outlet downstream to the middle of the air outlet, that is, in an area where a wind channel has a large width.

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.
