Abstract

L'invention concerne un moteur à rotor externe qui comprend un arbre de rotation (1), un stator (2) à conditionnement plastique et un rotor (3) externe. Le rotor (3) externe est gainé à l'extérieur du stator (2) à conditionnement plastique. Le stator (2) à conditionnement plastique comprend une base de gaine (21), un noyau de stator (22), une isolation d'extrémité (23), un enroulement de bobine (24) et un corps (25) à conditionnement plastique. Une pluralité de bras (211) dépassent vers l'extérieur depuis un sommet de la base de gaine (21), et une vis (5) est montée sur une extrémité éloignée des bras (211). Les bras (211) sont enveloppés dans le corps (25) à conditionnement plastique, et une partie de tige de vis de la vis (5) est découverte depuis une surface supérieure du corps (25) à conditionnement plastique. La présente invention comporte une structure simple, une résistance de structure considérable, et une haute fiabilité.
