Abstract

La présente invention concerne un stator de moteur électrique, comprenant : un noyau de fer (1), qui est pourvu d'une pluralité de fentes (1c) espacées dans une direction circonférentielle (C) ; et un enroulement (2), qui est monté sur le noyau de fer (1) et comprend des parties d'extension (22) qui s'étendent vers les deux côtés axiaux à partir de chaque fente (1c). Le stator de moteur électrique comprend en outre des ensembles de limitation (3), les ensembles de limitation (3) étant situés sur une face d'extrémité axiale du noyau de fer (1) et étant fixés au noyau de fer (1) ; et chaque ensemble de limitation (3) renferme un trou de limitation (3h), la paroi périphérique interne du trou de limitation (3h) venant en butée contre la partie d'extension (22) qui passe à travers le trou de limitation (3h), de telle sorte que, au moyen de la limitation des ensembles de limitation (3), au moins certaines des parties d'extension (22) sont fixées par rapport au noyau de fer (1) dans une direction radiale (R) et la direction circonférentielle (C). De cette manière, une structure mécanique relativement simple est utilisée pour éviter un mouvement de fil possible dans la direction radiale et la direction circonférentielle du stator de moteur électrique. L'invention concerne en outre un procédé d'assemblage pour le stator de moteur électrique, et un moteur électrique qui comprend le stator de moteur électrique.
