Title (EN) ELECTRIC MOTOR
(FR) MOTEUR ÉLECTRIQUE
(DE) ELEKTROMOTOR
Abstract:
(EN) The invention relates to an electric motor, in particular an external-rotor motor, comprising a rotor, a stator and a motor shaft, wherein the motor shaft has a rotation axis about which the rotor and the stator are rotatably mounted in relation to one another by means of a bearing, and wherein the motor shaft has a free end with an end face, and wherein an electrical contact-making element is arranged between the rotor and the stator. The invention proposes that the contact-making element has a first section and a second section, wherein the first section is arranged in the region of the bearing and the second section bears against the end face of the motor shaft such that it can move, in particular such that it can rotate, in relation to it.
(FR) L'invention concerne un moteur électrique, en particulier un moteur à induit extérieur, comportant un rotor, un stator et un arbre de moteur. Ledit arbre de moteur comprend un axe de rotation autour duquel le rotor et le stator sont montés de manière rotative l'un par rapport à l'autre par le biais d'un palier et l'arbre de moteur comporte une extrémité libre doté d'une surface frontale, et un élément de contact électrique est disposé entre le rotor et le stator. Selon l'invention, l'élément de contact comprend une première et une seconde section, la première section étant disposée dans la zone du palier et la seconde section étant mobile, en particulier rotative par rapport au palier au niveau de la surface frontale de l'arbre de moteur.
(DE) Die Erfindung betrifft einen Elektromotor, insbesondere einen Außenläufermotor, mit einem Rotor, einem Stator und einer Motorwelle, wobei die Motorwelle eine Drehachse aufweist um welche Rotor und Stator zueinander über eine Lagerung drehbar gelagert sind und wobei die Motorwelle ein freies Ende mit einer Stirnfläche aufweist und wobei zwischen Rotor und Stator ein elektrisches Kontaktierelement angeordnet ist. Es wird vorgeschlagen, dass das Kontaktierelement einen ersten Abschnitt und einen zweiten Abschnitt aufweist, wobei der erste Abschnitt im Bereich der Lagerung angeordnet ist und der zweite Abschnitt an der Stirnfläche der Motorwelle zu dieser bewegbar, insbesondere drehbar, anliegt.
