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 stator core is a laminated body formed by stacking, in the axial direction thereof, a plurality of steel plates having inner holes. A portion of the plurality of steel plates on a first side, which is one axial end side of the stator core, have notches formed at the same position in circumferential edges of the inner holes.

Un mode de réalisation de la présente invention est un dispositif de 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 eux. 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. Le noyau de stator est un corps stratifié formé par empilement, dans la direction axiale de celui-ci, d'une pluralité de plaques d'acier ayant des trous internes. Une portion de la pluralité de plaques d'acier sur un premier côté, qui est une extrémité axiale du noyau de stator, comporte des encoches formées dans la même position dans les bords circonférentiels des trous internes.
