(DE) STATORTRÄGER EINES GETRIEBELOSEN WINDGENERATORS
(EN) STATOR SUPPORT OF A GEARLESS WIND GENERATOR
(FR) SUPPORT DE STATOR D'UNE ÉOLIENNE À ENTRAÎNEMENT DIRECT
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.
