Title
(DE) STATORTRÄGER EINES GETRIEBELOSEN WINDGENERATORS
(EN) STATOR SUPPORT FOR A GEARLESS WIND GENERATOR
(FR) SUPPORT DE STATOR D'ÉOLIENNE SANS ENGRENAGE
Abstract
(DE)
Die Erfindung betrifft einen Statorträger (27) eines Stators (2) einer direkt angetriebenen Windgenerators (1) mit Außenläufer, welcher Statorträger (27) sich über ein Befestigungselement auf einer Lagereinheit (13) abstützt, wobei das Befestigungselement einen mit der Lagereinheit (13) verbindbaren Mittenflansch (8) aufweist, und sich in seinem radialen Verlauf nach außen axial in Richtung der Stirnseiten des Stators (2) erweitert, um radial unterhalb des Stators (2) einen Hohlraum (11) zu schaffen.
(EN)
The invention relates to a stator support (27) for a stator (2) of a direct drive wind generator (1) having an external rotor, which stator support (27) is supported on a bearing element (13) by a fixing element, wherein the fixing element has a central flange (8) which can be connected to the bearing unit (13), and the radial course of said fixing element in the direction of the exterior widens axially towards the end faces of the stator (2) in order to create a cavity (11) radially below the stator (2).
(FR)
L'invention concerne un support de stator (27) d'un stator d'une éolienne (1) à entraînement direct, à rotor extérieur, ledit support de stator (27) étant en appui sur une unité de support (13) par l'intermédiaire d'un élément de fixation, ledit élément de fixation présente un flasque médian (8) pouvant être relié à l'unité de support (13) et s'évase dans son étendue radiale vers l'extérieur dans la direction axiale des faces frontales du stator (2), de manière à former un espace creux (11) au-dessous du stator (2).
