Abstract
(EN) A resolver integrated-type bearing device (10) comprises: a bearing (20) that rotatably supports a rotary shaft (11) with respect to a housing (50); a rotor (31) attached to the rotary shaft (11); and a stator (32) disposed radially outward of the rotor (31) with a gap therebetween. A stator core (34) of the stator (32) is attached integrally with the bearing (20).
(FR) L'invention concerne un dispositif résolveur de type à palier intégré (10) comprenant: un palier (20) qui assure le support rotatif d'un arbre rotatif (11) par rapport à un boîtier (50); un rotor (31) fixé à l'arbre rotatif (11); et un stator (32) disposé radialement vers l'extérieur du rotor (31) avec un espace entre eux. Un noyau de stator (34) du stator (32) est fixé d'un seul tenant avec le palier (20).
