Title
(EN) AIR-COLLECTING DEFLECTOR FOR AN ELECTRICAL MACHINE
(FR) DEFLECTEUR COLLECTEUR D'AIR POUR UNE MACHINE ELECTRIQUE
Abstract
(EN)
A cover (10) for electrical machine frames with an air consolidated deflector (3) at the output side of the machine due to capture the fan driven ambient air which flows along the cooling ribs of the machine. At its internal face (1), i.e. in direction to the fan, the cover (10) incorporates a outer, oblique, ring-form deflector (3) and a concentric ring-form rim (4) with a number of fins (6) to form the air openings (7). In the centrl there is a central hole (5) for the shaft (E, Fig. 2) of the machine (M, Fig. 2). The holes (9) serves for the fastining of the cover (10).
(FR)
La présente invention décrit un couvercle (10) pour des bâtis de machines électriques avec un déflecteur d'air consolidé (3) situé du côté sortie de la machine et destiné à capter l'air ambiant entraîné par le ventilateur qui s'écoule le long des ailettes de ventilation de la machine. Sur sa face interne (1), à savoir dans la direction du ventilateur, le couvercle (10) comporte un déflecteur externe oblique, en forme de bague (3), ainsi qu'un bord annulaire concentrique (4) avec plusieurs ailettes (6) pour former des ouvertures d'air (7). Au centre se trouve un orifice central (5) pour l'arbre (E, Fig. 2) de la machine (M, Fig. 2). Les orifices (9) servent à la fixation du couvercle (10).
