Abstract

La présente invention concerne un moteur stratifié à courant continu à unité totalement fermée dont le noyau est stratifié par n unités de moteur en forme de disque et pénétré par un arbre moteur. Ces unités stratifiées de moteur sont stratifiées en alternance par des rotors et des stators. Chaque rotor est formé par une plaque tournante et plusieurs aimants permanents montés sur les plaques tournantes de manière à être alignés avec la polarité d’interphase ; une bague circulaire concentrique centrée par l’arbre est ainsi formée. Chaque stator est formé par des supports de stator et plusieurs bobines et les parois circonférentielles extérieures des supports de stator sont associées pour former une enveloppe du moteur, réalisant ainsi une structure totalement fermée. Les bobines sont montées sur les supports de stator à la manière de bagues circulaires concentriques qui correspondent à celles des aimants permanents des rotors. Les bobines peuvent être connectées en série, en parallèle ou en connexion série-parallèle, le fil conducteur étant relié à une carte de circuit imprimé extérieure contrôlable. La présente invention présente les avantages d’une grande efficacité, d’une économie de consommation d’énergie, d’une facilité de montage et d’entretien et dans la plupart des circonstances le moteur de la présente invention peut être réparé sans être éteint.
