Abstract

Dispositif d'introduction de bobine et un procédé d'introduction de bobine qui raccourcissent une extrémité de bobine. Ce dispositif d'introduction de bobine (100) introduit une bobine (10) dans une pluralité de fentes (21) d'un côté vers l'autre côté dans la direction axiale, ladite bobine (10) étant formée par enroulement d'un fil de bobine selon une forme d'anneau, ladite pluralité de fentes (21) traversant dans la direction axiale d'un noyau de stator (20). Le dispositif d'introduction de bobine (100) comprend : un mécanisme de déplacement de bobine disposé à l'intérieur du noyau de stator (20) dans la direction radiale et se déplaçant dans la direction axiale pour déplacer la bobine (10) ; une pluralité d'aubes (110) disposées dans la direction circonférentielle du noyau de stator (20) à l'intérieur du noyau de stator (20) dans la direction radiale et à l'extérieur du mécanisme de déplacement de bobine dans la direction radiale, s'étendant dans la direction axiale du noyau de stator (20), et maintenant la bobine (10) ; et un élément de connexion (130) connectant les autres côtés de la pluralité d'aubes (110) dans la direction axiale et se déplaçant d'un côté vers l'autre côté dans la direction axiale.
