Abstract

L'invention concerne un moteur à axe comportant un stator annulaire monté dans un carter. Le stator et le carter présentent un orifice joint recouvert d'une fine couche d'agent adhésif, formant un alésage traversant cylindrique. Un rotor comportant un arbre de rotor cylindrique est logé de manière rotative dans l'alésage traversant cylindrique, entouré par le stator, et relié activement à l'arbre de rotor. Un palier radial est disposé entre le rotor et le stator.
