The invention relates to a fan arrangement comprising a radial or diagonal fan (370) with which a direct current motor (32) is associated as drive motor, further comprising a digital control element (23, 24) such as a microcontroller or microprocessor, associated with that direct current motor (32), and comprising a program, associated with that digital control element (23, 24), for controlling the current flowing through the direct current motor (32), which program is embodied to generate a substantially constant current in the motor (32) in the working rotation speed range of the fan.
L'invention concerne un système de ventilation comprenant un ventilateur radial ou diagonal (370) auquel est associé un moteur à courant continu (32) en tant que moteur de commande; un organe de commande numérique (23, 24) qui est de type microcontrôleur ou microprocesseur et qui est associé au moteur à courant continu (32), et un programme de commande du courant qui parcourt le moteur à courant continu (32). Ce programme est associé à l'organe de commande numérique (23, 24) et est conçu de manière à produire un courant sensiblement constant dans le moteur (32) dans le régime de vitesse opérationnel du ventilateur.
