Title (EN) ELECTRIC WORKING MACHINE
(FR) MACHINE DE TRAVAIL ÉLECTRIQUE
Abstract:
(EN) An electric working machine including: a motor; a driving unit configured to be driven by the motor; a trigger switch configured to allow rotation of the motor; a power supply unit configured to supply electric power to the motor; and a control unit configured to control rotation of the motor, characterized in that: the electric working machine further comprises a switching element configured to perform short-circuiting between terminals of the motor to apply electronic braking, wherein the control unit is configured to perform adjustment of the braking by controlling the switching element when stopping the motor.
(FR) L'invention concerne une machine de travail électrique qui comprend: un moteur; une unité d'entraînement conçue pour être commandée par le moteur; un commutateur de déclenchement conçu pour permettre la rotation du moteur; une unité d'alimentation énergie conçue pour alimenter le moteur; et une unité de commande conçue pour commander la rotation du moteur. La machine de travail électrique se caractérise en ce qu'elle comprend en outre un élément de commutation conçu pour créer un court-circuit entre des bornes du moteur pour appliquer un freinage électronique. L'unité de commande est conçue pour accomplir le réglage du freinage par commande de l'élément de commutation au moment d'arrêter le moteur.
