Abstract

L'invention concerne un circuit (1) de contrôle moteur comprenant (i) une branche principale (10) permettant de piloter un moteur électrique (12) par l'intermédiaire d'un commutateur de contrôle (101), et (11) une branche de roue libre (11) placée en dérivation du moteur électrique (12) afin de protéger la branche principale du circuit (1) de contrôle moteur, ladite branche de roue libre (11) comprenant un dispositif de filtrage (111) comprenant au moins une inductance de filtrage (111A) pour filtrer les hautes fréquences d'un courant électrique traversant ladite branche de roue libre (11). L'invention concerne aussi un groupe moto-ventilateur pour véhicule automobile comprenant un tel circuit (1) de contrôle moteur.The invention relates to an engine control circuit (1) comprising (i) a main branch (10) for controlling an electric motor (12) via a control switch (101), and (11) a freewheel branch (11) placed as a bypass from the electric motor (12) in order to protect the main branch of the motor control circuit (1), said freewheel branch (11) comprising a filtering device (111) comprising at least a filter inductor (111A) for filtering the high frequencies of an electric current flowing through said freewheel branch (11). The invention also relates to a motor-driven fan unit comprising such an engine control circuit (1).
