Abstract

La présente invention concerne un procédé de câblage pour un moteur sans balai ayant une structure de barre omnibus simple, caractérisé par le câblage d'une bobine sur un stator comprenant un noyau ayant une forme creuse et une pluralité de dents faisant saillie à une distance régulière les unes des autres le long de la direction circonférentielle sur la circonférence interne du noyau, et, plus particulièrement, un procédé de câblage pour un moteur sans balai ayant une structure de barre omnibus simple caractérisé par le câblage d'une bobine, de sorte que tous les points neutres soient désignés par la pluralité de dents formées sur un arc semi-circulaire sur un côté de la partie centrale du noyau. La présente invention a été conçue pour résoudre le problème susmentionné, et en amenant les points neutres à être désignés sur la pluralité de dents formées sur l'arc semi-circulaire sur un côté de la partie centrale du noyau, des barres omnibus peuvent être positionnées de manière appropriée sur des phases U, V et W correspondantes, de sorte à permettre la fabrication d'une structure simple de barres omnibus, ce qui permet d'obtenir des effets significatifs tels que la réduction du coût de fabrication de barres omnibus.
