  • Rotary assembly with magnetic bearing
    Patent number: 11988587
    Abstract: The present invention relates to a rotary assembly (1), in particular for a rheological measurement apparatus, comprising: a stator (3), a rotor (2) that can rotate with respect to the stator (3), the rotor (2) being axially retained by an axial retaining means (4) preventing the movement of the rotor (2) along the axis of rotation (A) thereof, the axial retaining means (4) comprising a flexible rod suitable for being attached to a frame (5) and which allows a radial movement of the rotor (2), a magnetic bearing comprising a rotor element (6) made of magnetic material mounted on the rotor (2) and a stator element (7) made of magnetic material mounted on the stator (3), at least one of the rotor and stator elements made of magnetic material being a spherical magnet, wherein the rotary assembly (1) has a stable position in which the rotor (2) is aligned with the axis of rotation (A) thereof, and the elements made of magnetic material are facing each other along the axis of rotation (A) of the rotor and are
