Title (EN) ELECTRIC TOOL AND FASTENING METHOD USING THE SAME
(FR) OUTIL ÉLECTRIQUE ET PROCÉDÉ DE FIXATION L'UTILISANT
Abstract:
(EN) An electric tool in which a pulsating input voltage is configured to be supplied to a drive circuit of a motor (3), the electric tool including: a rotation speed detection unit configured to detect a rotation speed (42) of the motor (3), characterized in that the electric tool further includes: a control part (8) configured to vary a determining value for determining whether the rotation speed of the motor (3) satisfies a predetermined condition or not, so as to be synchronous, with a pulsation cycle of the input voltage supplied to the drive circuit.
(FR) L'invention concerne un outil électrique dans lequel une tension d'entrée en impulsion est conçue pour être fournie à un circuit de pilotage d'un moteur, l'outil électrique comprenant : une unité de détection de vitesse de rotation configurée pour détecter une vitesse de rotation du moteur, caractérisé en ce que l'outil électrique comprend en outre : une partie régulatrice configurée pour faire varier une valeur de détermination permettant de déterminer si la vitesse de rotation du moteur satisfait ou non une condition préétablie, afin d'être synchrone avec un cycle de pulsation de la tension d'entrée fournie au circuit de pilotage.
