Abstract

L'invention concerne les perceuses électriques de faibles dimensions. La perceuse 10 comporte un moteur électrique 12 qui est un moteur asynchrone poyphasé de quelques dizaines de watts. Un dispositif de commande d'alimentation 18, connecté au moteur par un câble 20, permet de régler indépendamment la vitesse de rotation et le couple du moteur, dans une certaine plate de vitesse. Application aux perceuses utilisées dans le domaine dentaire ou chirurgical.
