Abstract
(EN)
One embodiment of the present invention is a motor device provided with: a cylindrical member; and a stator provided with a stator core having an inner hole, an insulating member attached to the stator core, and a coil comprising a conducting wire wound on the stator core with the insulating member interposed therebetween. The stator core is attached to the cylindrical member such that an inner circumferential surface of the stator core is in contact with an outer circumferential surface of the cylindrical member. The insulating member has a cylindrical section that extends from the stator core along the outer circumferential surface of the cylindrical member. A projection that is in contact with the outer circumferential surface of the cylindrical member is formed at an end section on an inner circumferential surface of the cylindrical section. A recess is provided at a position on the outer circumferential surface of the cylindrical member, said position facing the projection.

Selon un mode de réalisation, la présente invention concerne un dispositif moteur comprenant : un élément cylindrique ; et un stator pourvu d'un noyau de stator ayant un trou interne, un élément isolant fixé au noyau de stator, et une bobine comprenant un fil conducteur enroulé sur le noyau de stator avec l'élément isolant interposé entre ceux-ci. Le noyau de stator est fixé à l'élément cylindrique de telle sorte qu'une surface circonférentielle interne du noyau de stator est en contact avec une surface circonférentielle externe de l'élément cylindrique. L'élément isolant a une section cylindrique qui s'étend à partir du noyau de stator le long de la surface circonférentielle externe de l'élément cylindrique. Une saillie qui est en contact avec la surface circonférentielle externe de l'élément cylindrique est formée sur une section d'extrémité sur une surface circonférentielle interne de la section cylindrique. Un évidement est ménagé dans une position sur la surface circonférentielle externe de l'élément cylindrique, ladite position faisant face à la saillie.
