Title (EN) GRINDER
(FR) MEULEUSE
(JA) グラインダ
Abstract:
(EN) The present invention provides a grinder which allows a large-sized smoothing capacitor and a reactor to be appropriately arranged. The grinder (1A) is provided with: a brushless motor (6); a motor housing (2) that houses the brushless motor (6); a handle housing (3) connected to the rear of the motor housing (2); an inverter circuit (47) for supplying a drive current to the brushless motor (6); a diode bridge (15) for converting an alternating current into a direct current and supplying the direct current to the inverter circuit (47); an electric field capacitor (C2) for smoothing an output current of the diode bridge (15); and a reactor (L2) provided in a current path of the brushless motor (6), wherein the electric field capacitor (C2) and the reactor (L2) are disposed behind the brushless motor (6).
(FR) La présente invention concerne une meuleuse qui permet à un condensateur de lissage de grande taille et à un réacteur d'être agencés de manière appropriée. La meuleuse (1A) est pourvue : d'un moteur sans balais (6) ; d'un logement de moteur (2) qui reçoit le moteur sans balais (6) ; d'un logement de poignée (3) connecté à l'arrière du logement de moteur (2) ; d'un circuit inverseur (47) destiné à fournir un courant d'entraînement au moteur sans balais (6) ; d'un pont de diodes (15) destiné à convertir un courant alternatif en un courant continu et à fournir le courant continu au circuit inverseur (47) ; d'un condensateur de champ électrique (C2) destiné à lisser un courant de sortie du pont de diodes (15) ; et d'un réacteur (L2) situé dans un trajet de courant du moteur sans balais (6), le condensateur de champ électrique (C2) et le réacteur (L2) étant disposés derrière le moteur sans balais (6).
(JA) 大型の平滑コンデンサ及びリアクトルを好適に配置可能なグラインダを提供する。グラインダ(1A)は、ブラシレスモータ(6)と、ブラシレスモータ(6)を収容するモータハウジング(2)と、モータハウジング(2)の後方に接続されるハンドルハウジング(3)と、ブラシレスモータ(6)に駆動電流を供給するインバータ回路(47)と、交流を直流に変換してインバータ回路(47)に供給するダイオードブリッジ(15)と、ダイオードブリッジ(15)の出力電流を平滑する電界コンデンサ(C2)と、ブラシレスモータ(6)の電流経路に設けられたリアクトル(L2)と、を備え、電界コンデンサ(C2)及びリアクトル(L2)が、ブラシレスモータ(6)よりも後方に配置されている。
