Abstract

L'invention concerne une carcasse isolante qui comprend une première carcasse isolante (200) et une seconde carcasse isolante (300) installées aux deux extrémités d'un noyau de stator de moteur. La première carcasse isolante (200) et des parties correspondantes de chacune des dents de stator (110) du noyau de stator (100) sont pourvues d'au moins deux entrées/sorties de ligne (210). Un côté extérieur de la première carcasse isolante (200) est également pourvu d'une encoche de ligne traversante (220) ménagée dans des couches. L'encoche de ligne traversante (220) passe à travers l'entrée/sortie de ligne. En ménageant l'encoche de ligne traversante (220) dans des couches, la présente invention peut procurer un chemin d'enroulement sans croisement pour une ligne de phase, évitant ainsi que des lignes de phase ne se croisent, ce qui permet de prévenir efficacement un court-circuit de la ligne de phase. La présente invention concerne également un stator comportant la carcasse isolante et un procédé d'assemblage de stator.
