Abstract

본 발명은 진공청소기용 팬모터에 관한 것으로, 회전축을 구비한 모터와, 상기 모터에 고정되는 엔드 브래키트와, 상기 모터의 회전축에 체결되는 임펠러와, 상기 모터의 소정부위에 임펠러를 감싸도록 고정되는 임펠러 커버와, 상기 임펠러의 후방측 엔드 브래키트에 고정되어 소음을 저감시키는 동시에 공기의 흐름을 원활하게 하는 가이드 베인과, 상기 가이드 베인 및 엔드 브래키트의 사이에 설치되는 보조 브래키트로 구성하여, 상기 가이드 베인과 보조 브래키트에 의한 공간부에 의하여 공기의 유동 소음을 현저하게 저감시키는 잇점이 있으며, 또한 공기의 흐름을 보다 원활하게 하여 마이너 로스(minor loss)를 감소시킴으로써 팬효율을 향상시키도록 한 것이다.The present invention relates to a fan motor for a vacuum cleaner, comprising: a motor having a rotating shaft, an end bracket fixed to the motor, an impeller fastened to the rotating shaft of the motor, and fixed to surround an impeller at a predetermined portion of the motor. Composed of an impeller cover, a guide vane fixed to the rear end bracket of the impeller to reduce noise and smooth air flow, and an auxiliary bracket installed between the guide vane and the end bracket. In addition, the guide vane and the space part by the auxiliary bracket have the advantage of remarkably reducing the flow noise of the air, and also improves the fan efficiency by reducing the minor loss by smoothing the air flow. It is to be.
