Abstract

L'invention concerne un capteur de couple sans contact, comprenant un élément générateur de force magnétique (1) et un élément conducteur de force magnétique (2). L'élément générateur de force magnétique (1) comprend de multiples paires d'aimants (11) dirigées radialement et uniformément réparties sur la même circonférence. L'élément conducteur de force magnétique (2) comprend une culasse d'aimant annulaire interne (21) et une culasse d'aimant annulaire externe (22) disposées de manière coaxiale et opposée, la culasse d'aimant annulaire interne ayant de multiples dents internes magnétiquement conductrices (231), et la culasse d'aimant annulaire externe ayant de multiples dents externes magnétiquement conductrices (232). Le capteur de couple forme un circuit magnétique fermé grâce à la génération d'un champ magnétique par l'intermédiaire des paires d'aimants (11) dans de multiples groupes d'ensembles d'acquisition de force magnétique (4) et la conduction de celle-ci vers la culasse d'aimant annulaire interne (21), la culasse d'aimant annulaire externe (22), des culasses d'aimant d'extraction (31, 32) et un troisième entrefer (33) disposé entre celles-ci par l'intermédiaire de paires de dents de conduction magnétique (23). La disposition structurale du capteur de couple réduit la quantité de fuite de flux magnétique et la réluctance magnétique du circuit magnétique fermé, ce qui permet d'améliorer la sensibilité du capteur et d'augmenter la linéarité des signaux mesurés par le capteur.
