摘要： A brushless fan motor, in which cooling effect on a stator may be enhanced, is provided. A center through hole is formed in a center of a bottom wall portion of a first brushless fan motor. Vane portions are formed on an inner wall portion of the brushless fan motor and are formed into a shape which allows ambient air to be drawn in through the center through hole. Through holes are formed in an end plate portion of the first brushless fan motor in order to introduce the ambient air, which has been drawn in through the center through hole, inside a rotor cover.

摘要： The present invention provides an axial flow fan capable of increasing an air volume and a static pressure more than conventional axial flow fans, and also capable of reducing generation of noise. A guide wall portion 33 is provided to form a guide groove 31 between the guide wall portion 33 and one stationary blade 11. The one stationary blade 11 is disposed in the vicinity of a lead wire engaging portion 25 provided at a housing 3. The guide groove 31 receives a plurality of lead wires 10 and guides the lead wires 10 to the lead wire engaging portion 25. When the guide wall portion 33 is provided and the lead wires 10 are received in the guide groove 31, presence of the lead wires 10 may have less adverse effect on the air volume and the static pressure, and may generate less noise.

摘要： An axial flow fan includes a blade having a curved portion formed in the vicinity of a radially outer end portion positioned opposite to the base portion in the radial direction of the peripheral wall portion of the hub. The curved portion is convex in the rotation direction, concave in the direction opposite to the rotation direction, and extends along the radially outer end portion of the blade. The curved portion extends from a rear end edge of the blade, positioned on a side where one end of the base portion of the blade is positioned, and extends in the radial direction of the hub to the vicinity of a front end edge of the blade, positioned on a side where the other end of the base portion of the blade is positioned and extending in the radial direction.
