Abstract

L'invention concerne une structure d'assemblage de rotor qui comprend plusieurs aimants permanents (1), un premier noyau de fer (2) de rotor et un second noyau de fer (3) de rotor. Le premier noyau de fer (2) de rotor comprend un premier anneau circulaire (22) et plusieurs premiers blocs conducteurs magnétiques (23) faisant saillie depuis l'extérieur du premier anneau circulaire (22), une première rainure (24) étant formée entre deux premiers blocs conducteurs magnétiques (23) adjacents ; le second noyau de fer (3) de rotor comprend un second anneau circulaire (32) et plusieurs seconds blocs conducteurs magnétiques (33) faisant saillie depuis l'extérieur du second anneau circulaire (32), une seconde rainure (34) étant formée entre deux seconds blocs conducteurs magnétiques (33) adjacents ; un élément crochet d'arrêt (230) droit dépassant du premier bloc conducteur magnétique (23) se situe sur le côté droit d'une première partie d'ouverture (240) de la première rainure supérieure (24); un élément crochet d'arrêt (330) gauche dépassant du second bloc conducteur magnétique (33) se situe du côté gauche d'une seconde partie d'ouverture (340) de la seconde rainure inférieure (34); la première rainure (24) et la seconde rainure (34) correspondent entre elles quant à leur position ; l'aimant permanent (1) est intégré dans la première rainure (24) et la seconde rainure (34) ; et l'aimant permanent (1) est défini par l'élément crochet d'arrêt (330) gauche et l'élément crochet d'arrêt (230) droit. Cette structure d'assemblage de rotor présente non seulement les avantages d'inhiber efficacement les bruits électromagnétiques, mais aussi de conférer une puissante efficacité magnétique, ce qui permet de réduire la quantité des enroulements de stator, de réduire les coûts du moteur et d'améliorer le rendement de celui-ci.
