Abstract

La présente invention concerne une roue de ventilateur radial (1), de préférence montée sur un moteur électrique (10), plus particulièrement un motor électrique d'aspirateur, comportant un disque de roue de ventilateur (8) muni d'aubes (2) de préférence courbes, avec une courbure externe (3) et une courbure interne (4). Dans le disque de la roue de ventilateur (8) sont ménagés des trous de passage (6). Pour obtenir une diminution de l'émission de bruit, l'invention propose que les trous de passage (6) d'une aube (2) soient ménagés sur sa courbure externe (3).
