Abstract

La présente demande concerne une base de connexion conductrice pour un stator de moteur, et un ensemble stator et un moteur. Le stator de moteur comprend une pluralité d'enroulements, chacun comprenant une première extrémité et une seconde extrémité. La base de connexion conductrice comprend : une première borne d'entrée principale ; et une première partie de connexion électrique, qui est électriquement connectée à la première borne d'entrée principale et configurée pour se connecter aux premières extrémités de certains des enroulements du stator de moteur. La base de connexion conductrice est configurée de telle sorte que les enroulements connectés à la première partie de connexion électrique sont connectés en parallèle les uns aux autres. Selon cette solution, les performances de sécurité du moteur sont améliorées. De plus, un papier isolant entre deux enroulements adjacents peut être omis, ce qui permet de réduire le coût du moteur.
