Abstract
A motor-operated fan apparatus is made up of a brushless motor and a centrifugal fan. The brushless motor has: a rotary shaft vertically disposed on a substrate in a rotatable manner; a stator disposed coaxially with the rotary shaft; and a rotor integrally disposed on the rotary shaft. The centrifugal fan has: a disk part which covers the brushless motor and is fixed to the rotary shaft; and a multiplicity of vane parts which are disposed so as to be elongated from an outer edge of the disk part. A ventilation control member is provided in a space between the rotor and the disk part to block the air flowing from the substrate side to the space between the rotor and the disk part.
