Title (EN) SPEED CONTROL SYSTEM FOR THE MOTOR OF A FAN AND MOTOR UNIT, IN PARTICULAR A HEATING AND/OR AIR-CONDITIONING UNIT FOR A MOTOR VEHICLE
(FR) SYSTÈME DE CONTRÔLE DE VITESSE D'UN MOTEUR DE GROUPE MOTO­-VENTILATEUR
Abstract: front page image
(EN)The invention relates to a speed control system for the motor of a fan and motor unit comprising a first and second transistors (3, 5) which are in parallel connected to each other and to a motor (1) through a continuous voltage source (7) which controls the rotation of said motor (1) and control means (9) for the field-effect first and second transistor (3, 5) in order to alternately ensure the operation of said two transistors in a linear mode for continuously powering the motor (1).
(FR)Système de contrôle de vitesse d'un moteur de groupe moto-­ventilateur, caractérisé en ce qu'il comporte: -un premier et un second transistors à effet de champ (3, 5) connectés en parallèle et reliés au moteur (1) au travers d'une source de tension (7) continue commandant la rotation du moteur (1), -un moyen de commande (9) des premier et second transistors à effet de champ (3, 5) pour assurer alternativement un fonctionnement en mode linéaire desdits deux transistors afin d'alimenter en continu le moteur (1).
