Abstract
(EN) An embodiment relates to a motor comprising: a shaft; a rotor coupled with the shaft; a stator arranged on the outside of the rotor a sensing magnet arranged on the shaft; and a coupling member arranged so as to cover the sensing magnet, wherein the coupling member is inserted into a first groove concavely formed in an end part of the shaft. Therefore, the motor can ensure that the sensing magnet and the shaft can be coupled and assembled by using a coupling member formed to have elastic structure.
(FR) Un mode de réalisation de la présente invention concerne un moteur comprenant : un arbre; un rotor accouplé à l'arbre; un stator disposé sur l'extérieur du rotor; un aimant de détection disposé sur l'arbre; et un élément d'accouplement placé de manière à recouvrir l'aimant de détection, l'élément d'accouplement étant inséré dans une première rainure formée de manière concave dans une partie d'extrémité de l'arbre. Par conséquent, le moteur peut garantir que l'aimant de détection et l'arbre peuvent s'accoupler et s'assembler au moyen d'un élément d'accouplement conçu pour présenter une structure élastique.
