特徴とする小型電動遠心フアンのフアンカバー。 A non-commutated DC motor consists of a stator fixed to the front surface of a substrate and a rotor rotatably pivoted to the stator. A large number of vanes facing in the radial direction are arranged in parallel on the front surface of the rotor. The fan cover is a bottomed cylindrical fan cover that covers a small electric centrifugal fan, the opening part of which fits into the base plate, the outer peripheral surface of which is provided with a plurality of exhaust ports facing the blade plate, and the front end surface of which is provided with a plurality of exhaust ports that face the blade plate. A fan cover for a small-sized electric centrifugal fan, characterized in that it has a connection port that faces in the direction of the rotational axis and that gradually decreases in diameter from the inner end of the blade plate and projects in the direction.
