Abstract

L'invention porte sur un système d'insertion de papier électriquement isolant dans des encoches d'un stator à partir d'un rouleau continu. Le papier électriquement isolant n'est pas coupé avant son insertion dans les encoches, et couvre donc complètement la surface du stator. Ledit système comprend un porte-stator configuré de façon à tenir le stator de façon rotative, un élément de support de papier déplaçable entre une position non fonctionnelle et une position fonctionnelle dans laquelle l'élément de support de papier maintient une partie insérée du papier isolant continu dans une encoche du stator, un ensemble de mise en forme et d'insertion déplaçable radialement entre une position rétractée et une position déployée dans laquelle l'ensemble de mise en forme et d'insertion entre dans l'une des encoches du stator, le papier isolant continu s'étendant entre l'ensemble de mise en forme et d'insertion et le stator, et le mouvement de l'ensemble de mise en forme et d'insertion vers la position déployée insérant une partie du papier isolant continu dans une encoche du stator.
