Abstract
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.
