Abstract

L'invention porte sur un rotor en aluminium coulé et sur un moteur utilisant le rotor en aluminium coulé. Le rotor en aluminium coulé comprend un noyau de rotor (1), des anneaux d'aluminium (2), et une bande d'aluminium conductrice (3) ; le milieu du noyau de rotor comporte un alésage d'arbre (11), les anneaux d'aluminium sont montés au niveau des extrémités du noyau de rotor, la bande d'aluminium conductrice passe à travers le noyau de rotor et connecte électriquement ensemble les anneaux d'aluminium au niveau des deux extrémités du noyau de rotor, et un renfoncement (12) est disposé sur au moins une face d'extrémité du noyau de rotor. Le rotor en aluminium coulé possède une structure simple, un faible poids, et un petit moment d'inertie, réduisant ainsi des pertes par friction et augmentant le rendement de moteur.
