Abstract
(EN)
An embodiment relates to a motor which comprises: a housing; a cover disposed to cover the housing; a stator disposed in the housing; a rotor disposed inside the stator; a shaft disposed in the center of the rotor; a sensing magnet disposed at the end of the shaft; and a circuit board including a sensor for sensing the sensing magnet, wherein the sensor is disposed inside a hole formed through the cover. Therefore, in the motor, a hole is formed through the cover disposed to cover an opening of the housing and a sensor is disposed inside the hole, so that a size of an axis direction of the motor can be reduced.

Un mode de réalisation de la présente invention concerne un moteur qui comprend : un boîtier ; un couvercle disposé de façon à recouvrir le boîtier ; un stator disposé dans le boîtier ; un rotor disposé à l'intérieur du stator ; un arbre disposé dans le centre du rotor ; un aimant de détection disposé à l'extrémité de l'arbre ; et une carte de circuit imprimé comprenant un capteur destiné à détecter l'aimant de détection, le capteur étant disposé à l'intérieur d'un trou formé à travers le couvercle. Par conséquent, dans le moteur, un trou est formé à travers le couvercle disposé de façon à recouvrir une ouverture du boîtier et un capteur est disposé à l'intérieur du trou, de telle sorte qu'une taille d'une direction d'axe du moteur puisse être réduite.
