Title (EN) FAN MOTOR
(FR) MOTEUR DE VENTILATEUR
(KO) 팬 모터
Abstract:
(EN) The present embodiment comprises: an inner housing having an inner space formed therein; a rotation shaft assembly supported in the inner housing and having a rotor and a bearing mounted on a rotation shaft thereof; a stator disposed to surround the rotor in the inner housing; an impeller connected to the rotation shaft; and an outer housing surrounding the outer periphery of the inner housing and having an inlet body, formed thereat, for guiding air to the impeller. The present embodiment is advantageous in that a heat dissipation vane is provided on the outer peripheral surface of the inner housing to guide air which passes between the inner housing and the outer housing after being suctioned into the inlet body, and thus when being guided by the heat dissipation vane, the air having been moved by the impeller can efficiently absorb heat transferred from the stator to the heat dissipation vane and more stably flow than when colliding against the stator and the rotor, and thus can be quickly discharged.
(FR) Un mode de réalisation de la présente invention comprend : un boîtier interne dans lequel est formé un espace interne; un ensemble arbre de rotation supporté dans le boîtier interne et comportant un rotor et un palier monté sur un arbre de rotation de celui-ci; un stator disposé de manière à entourer le rotor dans le boîtier interne; une roue de ventilateur reliée à l'arbre de rotation; et un boîtier externe qui entoure la périphérie externe du boîtier interne et qui comporte un corps d'entrée, formé au niveau de celui-ci, servant guider l'air vers la roue de ventilateur. Le présent mode de réalisation est avantageux en ce qu'une aube de dissipation de chaleur est disposée sur la surface périphérique externe du boîtier interne pour guider l'air qui passe entre le boîtier interne et le boîtier externe après avoir été aspirés dans le corps d'entrée, et ainsi lorsqu'il est guidé par l'aube de dissipation de chaleur, l'air ayant été déplacé par la roue de ventilateur peut absorber efficacement la chaleur transférée depuis le stator à l'aube de dissipation de chaleur et s'écouler de façon plus stable que lors d'une collision contre le stator et le rotor, et peut ainsi être évacué rapidement.
(KO) 본 실시예는 내부에 이너 공간이 형성된 이너 하우징과; 회전축에 로터와 베어링이 장착되고 이너 하우징에 지지된 회전축 어셈블리와; 이너 하우징에 로터를 둘러싸게 배치된 스테이터와; 회전축에 연결된 임펠러와; 이너 하우징의 외둘레를 둘러싸고 임펠러로 공기를 안내하는 인렛 바디가 형성된 아우터 하우징을 포함하고, 이너 하우징의 외둘레면에는 인렛 바디로 흡입된 후 이너 하우징과 아우터 하우징 사이를 통과하는 공기를 안내하는 방열 베인이 제공되어, 임펠러에 유동된 공기가 방열 베인에 안내되면서 스테이터에서 방열 베인으로 전달된 열을 효율적으로 흡열할 수 있고, 공기가 스테이터와 로터와 부딪히는 경우 보다 유동이 안정화될 수 있어, 공기를 신속하게 토출할 수 있는 이점이 있다.
