摘要： A control device comprising at least one permanent magnet, and a mechanically guided member for enabling a relative movement between a. a first ferromagnetic structure, b. a second ferromagnetic structure comprising at least one electric coil, the electric coil modifying the magnetization state of the second ferromagnetic structure in accordance with the direction and the amplitude of the electric current flowing in the coil, the device furthermore comprising a position detection means for detecting the relative position of the first and second ferromagnetic structures, and a circuit for driving the supply current of the coil, which varies as a function of the signal delivered by the position detection means.

摘要： The disclosure relates to a valve for controlling the circulation of a fluid, having a valve body and a housing containing an electric motor composed of a stator and of a rotor, a needle, a sealing bell and also a fixed screw or a fixed nut. The fixed screw or the fixed nut is secured to the valve body, and the stator is secured to the valve body via the housing. The sealing bell is positioned at the interface between the rotor and the stator in such a way that the screw/nut, the rotor and the needle are within this bell and submerged in the fluid, the stator being isolated from the fluid. Furthermore, the rotor has the function of a nut or of a screw, and has a helical movement imposed by the fixed screw or the fixed nut and drives the needle axially. The motor is a brushless polyphase motor with radial principal magnetic flux.

摘要： A module for detecting a rotating handle intended to be attached on a tube of a handlebar of a vehicle next to the handle includes a cylindrical magnet, a probe for detecting the magnetic field produced by the magnet, a support for the probe, a printed circuit board whereon the probe is secured, a support for the magnet and a flange used as a housing for the module. The magneto-sensitive probe detects rotation of the magnetic field emitted by the magnet and is secured to the handlebar, with the magnet and magnet holder being secured to the handle. The magnet and magnet holder form a cavity so that the inner radial surface of the magnet is positioned outside and opposite the magneto-sensitive probe. The magnet has a continuously variable magnetization direction so that the total rotation of the angle of the magnetic field generated by the magnet at the measuring point during the mechanical rotation of the handle is greater than 180°.

摘要： The present disclosure relates to an electromagnetic actuator of the type producing a force due to the current that remains substantially constant over the entirety of its useful travel Y and that has a low force in the absence of current, including at least one stator structure, at least one electrical supply coil, and a moving member, the stator structure having, on the one hand, a central pole running perpendicular to the direction of the travel Y and having a width YC1 in the direction of the travel and terminating at its end in a width YC2 that is greater than or equal to the travel Y of the moving member, YC2 being greater than YC1, and, on the other hand, two lateral poles having widths YL1 in the direction of the travel and terminating at their end in a width YL2 greater than YL1.
