Abstract

Dispositif de protection d’un capteur/émetteur La présente invention a pour objet principal un dispositif de protection (4) d’un capteur/émetteur (3) d’un véhicule (1), le dispositif de protection (4) comprenant un moteur électrique (18) couplé en rotation à un boîtier de protection (16) du capteur/émetteur, le moteur électrique (18) étant un moteur à commutation électronique comprenant un stator (28) et un rotor (26) tels que le stator (28) ou le rotor (26) porte un bobinage (34, 35) comportant au moins une bobine et alimenté en courant via une séquence commandée par un module de commande (30), le module de commande (30) étant configuré pour générer une instruction de commande principale dans laquelle l’alimentation du bobinage (34) est commandée selon une séquence principale définie pour créer un ensemble de champs magnétiques principal apte à entraîner en rotation le rotor (26) dans une plage de vitesses de rotation principale, caractérisé en ce que le module de commande (30) est par ailleurs configuré pour émettre une instruction de commande secondaire dans laquelle l’alimentation du bobinage (34) est commandée selon au moins une séquence d’échauffement distincte de ladite séquence principale de manière à générer un ensemble de champs magnétiques différent de l’ensemble de champs magnétiques principal et configuré pour générer un échauffement du moteur électrique (18) en laissant le rotor (26) immobile ou en rotation à une vitesse de valeur inférieure à celles de la plage de vitesses de rotation principale. Figure pour l’abrégé : Figure 2Device for protecting a sensor/transmitter The main object of the present invention is a device for protecting (4) a sensor/transmitter (3) of a vehicle (1), the protection device (4) comprising a motor electric motor (18) rotationally coupled to a protective casing (16) of the sensor/transmitter, the electric motor (18) being an electronically commutated motor comprising a stator (28) and a rotor (26) such that the stator (28 ) or the rotor (26) carries a winding (34, 35) comprising at least one coil and supplied with current via a sequence controlled by a control module (30), the control module (30) being configured to generate an instruction main control unit in which the supply of the winding (34) is controlled according to a main sequence defined to create a set of main magnetic fields able to drive the rotor (26) in rotation in a range of main rotation speeds, characterized in that that the control module (30) is not r further configured to issue a secondary control instruction in which the supply of the coil (34) is controlled according to at least one heating sequence distinct from said main sequence so as to generate a set of magnetic fields different from the set of main magnetic fields and configured to generate heating of the electric motor (18) leaving the rotor (26) immobile or rotating at a speed of a value lower than those of the main rotational speed range.
