Abstract: A passive haptic interface includes a first element which is rotatably movable about an axis or translatably movable along an axis, the first movable element rotating or moving opposite a second fixed element. The first movable element has a first plurality of magnetic poles spaced periodically at a pole pitch Ps and in the direction of movement, and the second fixed element has a second plurality of magnetic poles periodically spaced at a pole pitch Pr and in the direction of movement, where Ps and Pr are different numbers. A periodic stress is created by the magnetic interaction between the first movable element and the second fixed element in a period Pt. The pole pitches Ps and Pr are chosen such that Pt is strictly less than the smallest of the pitches Ps and Pr.

Abstract: The disclosure relates to a rotor for an electrical machine having internal permanent magnets including a yoke consisting of a stack of sheets defining a plurality of recesses for receiving parallelepipedal permanent magnets, the recesses being surrounded by magnetically saturated external transverse isthmuses, by radial isthmuses, lateral isthmuses and oblique isthmuses, wherein the magnets are assembled in pairs of magnets magnetized in the same direction and perpendicular to the radial direction of the radial isthmuses arranged between the coupled magnets, the radial isthmuses having a thickness of less than 5% of the diameter of the rotor, and the perimeter of the cross section of the rotor is formed by a succession of curved profiles, between two consecutive pairs of magnets, and tangential linear profiles at the external transverse isthmuses. The disclosure also relates to the application of such a rotor for creating a motor, in particular a motor for a turbo compressor, or an electrical generator.

Abstract: The disclosure presents a geared motor unit including a housing having an electric motor formed of a coiled stator assembly and of a magnetized rotor, the housing further including a printed circuit board for connecting and controlling the motor, a movement-reducing gear train, a sensor magnet and a magnetosensitive probe. The gear train includes a toothed movement output gear, the sensor magnet being ring-shaped and being rigidly connected to the output gear. An output gear is extended on either side of the sensor magnet by two guides cooperating with the two opposite walls of the housing; a ring-shaped magnet surrounds the axis of rotation of the output gear; a printed circuit board includes a controller controlling the motor and extends up to the vicinity of the output gear. The printed circuit board includes, in the area located in the vicinity of the output gear, the magnetosensitive probe which is connected directly, electrically and mechanically, to the area and is located axially or radially facing a ring-shaped magnet.
