Abstract:
(EN) Stator cores in which split cores having rotatable connection sections are connected via the connection sections so as to form a cylindrical shape, wherein the split cores (60, 60A, 60B) are each provided with an arc-shaped protrusion provided to one edge of a back yoke (32b) in the circumferential direction on a tooth (32C) side, and an arc-shaped hole (81) provided to the other edge of the back yoke (32b) in the circumferential direction on the opposite side to the side where the protrusion (82) is positioned. The connection sections are configured such that the protrusion (82) of one adjacent split core (60, 60A, 60B) fits into the hole (81) of another split core (60, 60A, 60B), and the arc-shaped outer peripheral surface (82C) of the protrusion (82) makes contact and engages with the arc-shaped inner wall (81C) of the hole (81).
(FR) L'invention concerne des noyaux de stator dans lesquels des noyaux séparés ayant des sections de connexion rotatives sont reliés via les sections de connexion de manière à former une forme cylindrique, dans lesquels les noyaux séparés (60, 60A, 60B) comportent chacun une protubérance en forme d'arc disposée sur un bord d'une culasse arrière (32b) dans la direction circonférentielle sur un côté dent (32C), et un trou en forme d'arc (81) formé sur l'autre bord de la culasse arrière (32b) dans la direction circonférentielle sur le côté opposé au côté où est positionnée la protubérance (82). Les sections de connexion sont configurées de telle sorte que la protubérance (82) d'un noyau divisé adjacent (60, 60A, 60B) s'adapte dans le trou (81) d'un autre noyau divisé (60, 60A, 60B), et que la surface périphérique externe en forme d'arc (82C) de la protubérance (82) vienne en contact et en prise avec la paroi interne en forme d'arc (81C) du trou (81).
(JA) 回動可能な連結部を有する分割鉄心を、連結部にて連結し、円筒形に構成した固定子鉄心において、分割鉄心(60,60A,60B)に、バックヨーク(32b)の周方向の端部の他方にティース(32c)側が円弧形状の突起(82)と、バックヨーク(32b)の周方向の端部の一方に突起(82)が配置された側とは反対側が円弧形状の穴(81)と、を設け、連結部を、一つの分割鉄心(60,60A,60B)の穴(81)に、隣接する他の分割鉄心(60,60A,60B)の突起(82)を嵌め込み、突起(82)の円弧形状の外周面(82C)が穴(81)の円弧形状の内壁(81C)に接し、係合するように構成した。
