Abstract

La présente invention concerne un moteur comprenant : une denture extérieure sur laquelle est enroulée une première bobine ; un stator circulaire présentant une pluralité d'ensembles noyaux divisés qui sont espacés dans le sens circonférentiel, ces ensembles noyaux présentant une denture intérieure sur laquelle est enroulée une seconde bobine qui est reliée à la première bobine ; un support de rotor relié à un arbre tournant ; un rotor extérieur, qui est fixé à l'extérieur du support de rotor et positionné sur l'extérieur du stator, et qui forme un premier circuit magnétique par interaction avec la première bobine ; et un rotor, qui est fixé à l'intérieur du support de rotor et agencé à l'intérieur du stator et pourvu d'un rotor intérieur, et qui forme un second circuit magnétique par interaction avec la seconde bobine. La présente invention permet de réduire la perte de force magnétique par réduction de la résistance magnétique, d'améliorer le rendement du moteur, de réduire les coûts de fabrication, d'accroître la simplicité d'assemblage et de réduire au minimum le bruit et les vibrations.
