Abstract
(EN)
This motor according to an embodiment is provided with a shaft that serves as a rotating axis, a rotor, bearings, and a spring member. The rotor is fixed to the shaft. The bearings are arranged facing the rotor in the rotating axis direction and rotatably support the shaft. The spring member is arranged between the rotor and the bearings and has one end fixed to the rotor.

Ce moteur selon un mode de réalisation est pourvu d'un arbre qui sert d'axe de rotation, d'un rotor, de paliers et d'un élément de ressort. Le rotor est fixé à l'arbre. Les paliers sont agencés face au rotor dans la direction de l'axe de rotation et supportent de manière rotative l'arbre. L'élément de ressort est disposé entre le rotor et les paliers et a une extrémité fixée au rotor.
