Abstract

L’invention concerne un dispositif de mesure de position (1) pour machine électrique tournante (2) comprenant un stator (3) et un rotor (4), le dispositif comprenant au moins un capteur de flux magnétique (7) supporté par une plaque de support (17), au niveau d’une extrémité de mesure (8), et étant destiné à être monté sur un flasque (6) de façon que l’extrémité de mesure soit disposée en face du rotor en étant espacée du rotor. Selon l’invention, le dispositif comprend un connecteur électrique (14) distant de la plaque de support et s’étend suivant une direction axiale depuis le rotor et au-delà du flasque, le connecteur électrique étant positionné dans une partie externe (10) séparée axialement de l’extrémité de mesure par le flasque, le dispositif de mesure comprenant au moins une broche de connexion (13) s’étendant axialement depuis le connecteur électrique jusqu’à la plaque de support. Figure de l’abrégé : Fig. 1The invention relates to a position measuring device (1) for a rotating electrical machine (2) comprising a stator (3) and a rotor (4), the device comprising at least one magnetic flux sensor (7) supported by a plate support (17), at a measuring end (8), and being intended to be mounted on a flange (6) so that the measuring end is arranged opposite the rotor while being spaced from the rotor. According to the invention, the device comprises an electrical connector (14) spaced from the support plate and extending in an axial direction from the rotor and beyond the flange, the electrical connector being positioned in an external part (10) separated axially from the measuring end by the flange, the measuring device comprising at least one connection pin (13) extending axially from the electrical connector to the support plate.
