Title (EN) ROTATING ELECTRICAL MACHINE INCLUDING A MAGNETIC POSITION SENSOR
(FR) MACHINE ELECTRIQUE TOURNANTE INTEGRANT UN CAPTEUR DE POSITION MAGNETIQUE
Abstract:
(EN) The invention relates to a rotating electrical machine (100) including a magnetic sensor (101) for obtaining the angular position of the rotor (150). The sensor comprises a rotating part (108) with a magnet (102), which is secured to the end (160b) of the rotating shaft (160) at the rear of the machine and faces a stationary part (103) comprising Hall effect sensors and mounted on a stationary support (106) connected to the casing of the machine. The machine comprises a bearing (104) centred on the axis (X), separating the rotating and stationary parts of the sensor. The bearing, which is secured to the shaft and to the metal support of the stationary part of the sensor, and preferably in contact with the rotating part, forms a new mechanical reference close to the sensor. The invention supplies precise and robust position information, irrespective of mechanical and magnetic disturbances that may occur on the shaft.
(FR) L'invention porte sur une machine électrique tournante (100) intégrant un capteur magnétique de position angulaire (101 ) du rotor (150). Le capteur comporte une partie tournante (108) avec aimant (102) fixée à l'extrémité (160b) de l'arbre de rotation (160) à l'arrière de la machine, en regard d'une partie fixe (103) comprenant des capteurs à effet Hall et montée sur un support fixe (106) relié à la carcasse de la machine. La machine comporte un palier (104) centré sur l'axe (X), désolidarisant les parties tournante et fixe du capteur. Ce palier, fixé à l'arbre et au support métallique de la partie fixe du capteur, et préférentiellement en contact avec la partie tournante, constitue une nouvelle référence mécanique proche du capteur. L'invention fournit une information précise et robuste de la position indépendamment des perturbations mécaniques et magnétiques pouvant se produire sur l'arbre.
