Abstract
L'invention porte principalement sur une machine électrique tournante comportant un rotor monté sur un arbre s'étendant suivant un axe correspondant à l'axe de rotation du rotor et au moins un palier (18) comportant un logement recevant un roulement pour le montage à rotation de l'arbre, - ladite machine électrique tournante comportant en outre un dispositif de mesure de la position angulaire du rotor comprenant: - une rondelle cible montée autour de l'arbre, - un support (47) d'au moins un capteur de mesure de champ magnétique, et - une rondelle de maintien (51) du support (47), ladite rondelle de maintien (51) étant fixée sur le palier (18), caractérisée en ce que le dispositif de mesure comporte un moyen de déformation axiale (61) de la rondelle de maintien (51) pour compenser des déformations du support de capteurs (47) notamment dues à des variations de température.The invention relates mainly to a rotary electrical machine comprising a rotor mounted on a shaft extending along an axis corresponding to the axis of rotation of the rotor and at least one bearing (18) comprising a housing receiving a bearing for mounting at rotation of the shaft, - said rotary electrical machine further comprising a device for measuring the angular position of the rotor comprising: - a target washer mounted around the shaft, - a support (47) of at least one sensor for magnetic field measurement, and - a retaining washer (51) of the support (47), said retaining washer (51) being fixed on the bearing (18), characterized in that the measuring device comprises an axial deformation means (61) of the retaining washer (51) to compensate for deformations of the sensor support (47) in particular due to temperature variations.
