Abstract

Détecteur tachymétrique, notamment pour un ventilateur 1 de type plat, à moteur électrique asynchrone. Le rotor 6 porte au moins un aimant permanent 8, disposé en regard d'une bobine d'induction 9 solidaire du stator 2. Un circuit de contrôle est relié à la bobine 9. Chaque aimant permanent 8 du rotor est logé dans une cavité d'une bague de court-circuit 13 du rotor. La bobine 9 est fixée dans le fond 4 du carter 3. De préférence, les éléments 8, 9, du détecteur sont fixés par collage dans des logements exactement ajustés. Application aux détecteurs tachymétriques de sécurité, notamment pour contrôler le fonctionnement de ventilateurs de refroidissement de type plat, de faible encombrement
