Abstract

Ce dispositif est caractérisé en ce qu'il comprend un élément 2 détecteur du nombre de tours du moteur à commander, lequel émet des impulsions électriques qui correspondent au nombre de tours effectifs du moteur, un organe électronique 3 de sélection branché sur l'élément 2 et servant à comparer les signaux qu'il émet à un signal correspondant à la vitesse sélectionnée, et à émettre un signal indiquant que la vitesse sélectionnée est atteinte par le moteur, un amplificateur 5 servant à recevoir et à amplifier ce signal, et un dispositif électronique interrupteur servant à couper l'alimentation du moteur lorsque ladite vitesse est atteinte.
