Abstract

Ce dispositif de surveillance (22) d'une machine électrique synchrone à aimants permanents de traction d'un véhicule automobile comprend un premier module de détermination (24) d'un flux au rotor de la machine électrique, un second module de détermination (50) d'une température de rotor de la machine électrique, le second module de détermination (50) tenant compte du flux au rotor déterminé par le premier module de détermination (24). Le dispositif (22) comprend un moyen de réception (48) d'une température connue, d'une vitesse de rotation connue et d'une force électromotrice de réglage, la force électromotrice de réglage correspondant à la force électromotrice à vide de la machine électrique à la température connue et à la vitesse de rotation connue, le second module de détermination (50) tenant compte de la température connue, de la vitesse de rotation connue et de la force électromotrice de réglage reçues par le moyen de réception (48).This monitoring device (22) of a synchronous electric machine with permanent traction magnets of a motor vehicle comprises a first module for determining (24) a flux at the rotor of the electric machine, a second module for determining (50 ) a rotor temperature of the electric machine, the second determination module (50) taking into account the flux at the rotor determined by the first determination module (24). The device (22) comprises means (48) for receiving a known temperature, a known speed of rotation and an electromotive adjustment force, the electromotive adjustment force corresponding to the empty electromotive force of the machine electric at the known temperature and at the known speed of rotation, the second determination module (50) taking into account the known temperature, the known speed of rotation and the electromotive adjustment force received by the receiving means (48) .
