(JA) 電動工具
Abstract
(EN) The purpose of the present disclosure is to provide an electric tool in which the diameter of a rotor is easily made shorter. This electric tool comprises a motor (1). The motor (1) comprises a stator core (20) and a rotor (5). The rotor (5) rotates with respect to the stator core (20). The rotor (5) includes: a cylindrical rotor core (6); a plurality of permanent magnets (7); and an output shaft (51). The output shaft (51) is held on the inner side of the rotor core (6). The plurality of permanent magnets (7) are disposed about the center of the rotor core (6) in a spoke shape.
(FR) La présente invention concerne un outil électrique dans lequel le diamètre d'un rotor est facilement raccourci. Cet outil électrique comprend un moteur (1). Le moteur (1) comprend un noyau de stator (20) et un rotor (5). Le rotor (5) tourne par rapport au noyau de stator (20). Le rotor (5) comprend : un noyau de rotor cylindrique (6) ; une pluralité d'aimants permanents (7) ; et un arbre de sortie (51). L'arbre de sortie (51) est retenu sur le côté interne du noyau de rotor (6). La pluralité d'aimants permanents (7) sont disposés autour du centre du noyau de rotor (6) selon une forme en rayon.
(JA) 本開示は、ロータの直径を短くしやすい電動工具を提供することを目的とする。電動工具は、モータ(1)を備える。モータ(1)は、ステータコア(20)と、ロータ(5)と、を備える。ロータ(5)は、ステータコア(20)に対して回転する。ロータ(5)は、円筒状のロータコア(6)と、複数の永久磁石(7)と、出力軸(51)と、を有する。出力軸(51)は、ロータコア(6)の内側に保持されている。複数の永久磁石(7)は、ロータコア(6)の中心を中心としてスポーク状に配置されている。
