Abstract

Dispositif électronique de contrôle de la rotation d'une pièce tournante et circuit de sécurité le comportant Il comporte un aimant permanent 9 solidaire de la pièce tournante 8 et passant devant un inducteur 7 à chaque tour de la pièce, l'inducteur 7 alimentant la base d'un transistor 11 de commutation qui décharge un condensateur 13 à chaque passage de l'aimant 9 devant l'inducteur 7, le condensateur 13 étant chargé à travers une résistance 16 par une source de tension continue 15. Lors de l'arrêt du mouvement rotatif, le condensateur 13 se charge à une tension élevée qui déclenchera un thyristor 19 dont la gâchette est reliée par l'intermédiaire d'un diac 18 à ce condensateur 13. L'invention est applicable aux machines à laver séchantes où l'arrêt du tambour peut endommager le linge.
