Abstract[English]
The present invention relates to a wheel hub motor (300) for a work tool (100), such as a lawn mower. The motor comprises a support member (310), a stator assembly (320), a rotor assembly (330) configured to partially enclose the stator assembly in an inner space (338) of the rotor assembly and a bearing assembly (340). The rotor assembly is rotatably supported on the support member through the bearing assembly for rotation of the rotor assembly about a rotation axis (A). The rotor assembly comprises a rotor portion (332), configured to at least partly enclose the stator assembly, and a motor cover portion (334), configured to at least partly cover a first axial side (324) of the stator assembly. The rotor assembly is rotatably supported by the bearing assembly only between a first end portion (312) of the support member and the first axial side of the stator assembly.[French]
La présente invention se rapporte à un moteur de moyeu de roue (300) pour un outil de travail (100), tel qu'une tondeuse à gazon. Le moteur comprend un élément de support (310), un ensemble stator (320), un ensemble rotor (330) configuré pour enfermer partiellement l'ensemble stator dans un espace interne (338) de l'ensemble rotor et un ensemble palier (340). L'ensemble rotor est supporté en rotation sur l'élément de support par l'intermédiaire de l'ensemble palier pour la rotation de l'ensemble rotor autour d'un axe de rotation (A). L'ensemble rotor comprend une partie rotor (332), configurée pour entourer au moins partiellement l'ensemble stator, et une partie couvercle de moteur (334), configurée pour recouvrir au moins partiellement un premier côté axial (324) de l'ensemble stator. L'ensemble rotor est supporté en rotation par l'ensemble palier uniquement entre une première partie d'extrémité (312) de l'élément de support et le premier côté axial de l'ensemble stator.
