Abstract
(EN)
Provided is a power tool distributed winding motor that can prevent an increase in the size of a power tool. This power tool distributed winding motor comprises: a stator having a stator core in which coils are distributed in a plurality of slots and wound therein; a rotor having a shaft that rotates with respect to the stator and outputs a driving force for a working part of a power tool; and an overlap section that is provided separately from the shaft and that is arranged so as to overlap coil ends, of the coils, that protrude from the stator core in the axial direction of the central axis of the rotor, in the axial direction of the rotor.
(FR)
L'invention concerne un moteur à enroulement distribué d'outil électrique qui peut empêcher une augmentation de la taille d'un outil électrique. Ce moteur à enroulement distribué d'outil électrique comprend : un stator ayant un noyau de stator dans lequel des bobines sont réparties dans une pluralité de fentes et enroulées dans celles-ci ; un rotor ayant un arbre qui tourne par rapport au stator et délivre une force d'entraînement pour une partie de travail d'un outil électrique ; et une section de chevauchement qui est disposée séparément de l'arbre et qui est agencée de façon à chevaucher les extrémités de bobine, des bobines, qui font saillie à partir du noyau de stator dans la direction axiale de l'axe central du rotor, dans la direction axiale du rotor.
(JA)
電動工具の大型化を抑制できる電動工具用の分布巻きモータを提供する。電動工具用の分布巻きモータは、複数個のスロットに分布してコイルが巻かれたステータコアを有するステータと、ステータに対して回転して電動工具の作業部に対する駆動力を出力するシャフトを有するロータと、シャフトとは別個に設けられ、コイルのうちステータコアからロータの中心軸の軸線方向に突出したコイルエンドに対して、ロータの軸線方向にオーバーラップして配置されるオーバーラップ部とを備える。
