Title (EN) MOTOR AND MOTOR MANUFACTURING METHOD
(FR) MOTEUR ET PROCÉDÉ DE FABRICATION DE MOTEUR
(JA) モータおよびモータの製造方法
Abstract:
(EN) This motor is provided with: a rotor that has a shaft disposed along the center axis extending in the vertical direction and that rotates about the center axis; and a stator that opposes the rotor via a gap in the radial direction; a housing that has a cylindrical portion surrounding the stator from the radially outer side; a bearing that rotatably supports the shaft; and a bearing holder that is held in the cylindrical portion and supports the bearing. A groove portion that extends along the circumferential direction is provided on the inner circumferential surface of the housing, and the bearing holder has an outer peripheral portion that is stored in the groove portion.
(FR) Ce moteur est pourvu : d'un rotor qui a un arbre disposé le long de l'axe central s'étendant dans la direction verticale et qui tourne autour de l'axe central ; et d'un stator qui fait face au rotor par l'intermédiaire d'un espace dans la direction radiale ; un logement qui a une partie cylindrique entourant le stator à partir du côté radialement externe ; un palier qui supporte de façon rotative l'arbre ; et un support de palier qui est maintenu dans la partie cylindrique et supporte le palier. Une partie de rainure qui s'étend le long de la direction circonférentielle est disposée sur la surface circonférentielle interne du boîtier, et le support de palier a une partie périphérique externe qui est stockée dans la partie de rainure.
(JA) 上下方向に延びる中心軸に沿って配置されたシャフトを有し中心軸周りに回転するロータと、ロータと径方向に隙間を介して対向するステータと、ステータを径方向外側から囲む筒状部を有するハウジングと、シャフトを回転可能に支持するベアリングと、筒状部に保持されベアリングを支持するベアリングホルダと、を備え、ハウジングの内周面には、周方向に沿って延びる溝部が設けられ、ベアリングホルダは、溝部に収納される外縁部を有する、モータ。
