Abstract

La présente invention concerne un compresseur à vis, et plus particulièrement un compresseur à vis qui est intégré à un moteur synchrone, qui possède une structure simple sans raccord ni palier, et qui comprend : une extrémité d'air incluant deux rotors femelles, ainsi qu'une vis principale faisant tourner les rotors femelles et ayant un arbre rotatif conçu pour s'étendre ; et un moteur synchrone comportant un rotor qui possède un trou d'arbre que l'arbre rotatif traverse, un stator qui se trouve sur le côté extérieur du rotor de manière à générer une force magnétique, ce qui permet de faire tourner ce rotor, et des bobines de stator appartenant au stator de façon à aimanter ledit stator grâce à l'énergie électrique fournie, ledit arbre rotatif étant raccordé puisqu'il traverse directement le trou d'arbre du rotor, de telle sorte que la puissance de rotation du rotor soit transmise directement à l'arbre rotatif.
