Title
(EN) POWER TOOL
(FR) OUTIL ÉLECTRIQUE
Abstract
(EN) A power tool includes: a rechargeable battery; a motor; a drive circuit; an operation unit; a battery state detection circuit; a control circuit; and an interruption circuit. The battery state detection circuit detects a battery voltage, and when the detected battery voltage is lower than or equal to a prescribed voltage, the battery state detection circuit outputs a low-voltage signal. The control means outputs a control signal to the drive circuit instructing to drive the motor when the operation unit is operated and halts the output of the control signal to the drive circuit instructing to halt driving the motor in response to the low-voltage signal. The interruption circuit outputs an interruption signal to the drive circuit in response to the low-voltage signal to thereby interrupt the drive circuit and halt driving the motor irrespective of whether or not the control signal is outputted to the drive circuit.
(FR) Outil électrique comprenant : une batterie rechargeable; un moteur; un circuit d'entraînement; une unité d'actionnement; un circuit de détection d'état de batterie; un circuit de commande; et un circuit d'interruption. Le circuit de détection d'état de batterie détecte une tension de batterie, et lorsque la tension de batterie détectée est inférieure ou égale à une tension prescrite, le circuit de détection d'état de batterie émet un signal de faible tension. Le moyen de commande émet un signal de commande de circuit d'entraînement donnant l'ordre d'entraîner le moteur lorsque l'unité d'actionnement est actionnée et arrête l'émission du signal de commande en direction du circuit d'entraînement donnant l'ordre d'arrêter l'entraînement du moteur en réponse au signal de faible tension. Le circuit d'interruption émet un signal d'interruption en direction du circuit d'entraînement en réponse au signal de faible tension pour interrompre ainsi le circuit d'entraînement et arrêter l'entraînement du moteur, que le signal de commande soit émis ou non en direction du circuit d'entraînement.
