Title
(EN) POWER TOOL
(FR) OUTIL ÉLECTRIQUE
(JA) 動力工具
Abstract
(EN)
This power tool comprises: a motor having a rotor and a stator disposed around the rotor; an output shaft to which a tip tool is attached and which is rotated by power generated by the motor; a torque sensor part disposed, in a longitudinal direction parallel to the rotation axis of the motor, between the stator and the output shaft, and connected to the output shaft; an amplifier circuit for amplifying a detection signal from the torque sensor part; and a housing having a motor accommodation part for accommodating the motor, and a grip part. The torque sensor part is disposed forward of the stator.
(FR)
Cet outil électrique comprend : un moteur présentant un rotor et un stator disposé autour du rotor ; un arbre de sortie auquel est fixé un outil de pointe et qui est entraîné en rotation par l'énergie générée par le moteur ; une partie capteur de couple disposée, dans une direction longitudinale parallèle à l'axe de rotation du moteur, entre le stator et l'arbre de sortie, et raccordée à l'arbre de sortie ; un circuit amplificateur destiné à amplifier un signal de détection provenant de la partie capteur de couple ; et un boîtier présentant une partie de réception de moteur destinée à recevoir le moteur et une partie de préhension. La partie capteur de couple est disposée en avant du stator.
(JA)
動力工具は、ロータ及びロータの周囲に配置されるステータを有するモータと、先端工具が取り付けられモータが発生する動力により回転する出力軸と、モータの回転軸と平行な前後方向においてステータと出力軸との間に配置され出力軸に連結されるトルクセンサ部と、トルクセンサ部の検出信号を増幅する増幅回路と、モータを収容するモータ収容部及びグリップ部を有するハウジングと、を備える。トルクセンサ部は、ステータよりも前方に配置される。グリップ部は、モータ収容部よりも下方に配置される。増幅回路は、グリップ部よりも上方に配置される。増幅回路は、ステータの後端部よりも前方に配置される。
