Abstract:
(EN) An impeller (100), fan and motor, the impeller (100) comprising an approximately conical hub (11) and a plurality of blades (12), provided at intervals along a circumferential direction on a peripheral surface of the hub (11). The blades comprise a front edge surface (121) at an inlet end and a rear edge surface (122) at an outlet end. The blades are flat plates that have been twisted. Rear edge sections of the blades are twisted relative to a circumferential direction and form slopes.
(FR) L’invention concerne une roue (100), un ventilateur et un moteur, la roue (100) comprenant un moyeu approximativement conique (11) et une pluralité de pales (12), disposées à des intervalles le long d'une direction circonférentielle sur une surface périphérique du moyeu (11). Les pales comprennent une surface de bord avant (121) au niveau d'une extrémité d'entrée et une surface de bord arrière (122) au niveau d'une extrémité de sortie. Les pales sont des plaques plates qui ont été torsadées. Des sections de bord arrière des pales sont torsadées par rapport à une direction circonférentielle et forment des pentes.
(ZH) 一种叶轮(100)、风机和电机,所述叶轮(100)包括大致锥形的轮毂(11)和沿周向间隔布置在所述轮毂(11)的外周面上的多个叶片(12),所述叶片包括位于进口端的前缘面(121)和位于出口端的后缘面(122),所述叶片为平板扭曲叶片,所述叶片的叶片后缘段相对于圆周方向旋扭倾斜。
