摘要： An electric motor includes a cylindrical wound stator assembly forming a free interior space and a rotor assembly guided inside the interior space. The reduction gear is inside a housing secured to the stator assembly and having a movable gearing assembly. The output of the movable gearing assembly is secured to a movement output shaft. The input element of the movable gearing is driven by the rotor assembly extending inside the housing. The gear motor comprises a guide element of the output shaft. The output shaft is extended inside the motor up to a guide element located at least partly inside the stator assembly having the rotor assembly which is guided by a guide means positioned between the inner surface of the rotor assembly and a surface of the output shaft.

摘要： 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.

摘要： A position sensor, in particular, intended for detecting the torsion of a steering column, includes a first magnetized rotor structure comprising magnets, a second stator structure comprising two rings extended by teeth that are axially oriented and interlocked, and a third stationary collector structure including two flux collection parts that define at least one air gap in which at least one magnet-sensitive element is placed. The flux collection parts and the ring gears define a magnetic permeance independent of the relative radial and angular position of the second stator structure with respect to the third collector structure. The collection parts comprise an angular collection sector and a primary collection zone continued by a prolongation having a secondary collection zone. The secondary collection zones end in flat extensions forming two poles of the air gap. The transverse median plane of the air gap intersects at least one of the prolongations.

摘要： An actuator for controlling the movement of an element between two stable positions with pulsed electrical control without a change in polarity comprises: a ferromagnetic mobile mass, at least one electrically controlled wire coil that is fixed with respect to the mobile mass, at least two ferromagnetic poles that are fixed with respect to the mobile mass and on either side of the mobile mass. The actuator comprises at least one permanent magnet that attracts the mobile mass in order to achieve the two stable positions. The mobile mass defines, with the ferromagnetic poles, at least two variable air gaps during the movement of the mobile apparatus. The magnetic flux of the permanent magnet opposes the magnetic flux generated by the at least one coil regardless of the position of the mobile mass.

摘要： A rotary actuator with a moving frame includes an electrical coil that moves on an angular travel about an axis of rotation A, the shape of the coil being an elliptical cylinder and the axis of winding B being orthogonal to the axis of rotation A, the coil being placed in the magnetic field of a fixed magnet. The fixed magnet surrounds the coil and includes two semicylindrical portions, the generatrices of which are orthogonal to the axis of rotation A, the first of the semicylindrical portions having a north pole directed toward the coil, orthogonally to the direction of the generatrices and being positioned outside the coil, the second having a south pole directed toward the coil, orthogonally to the direction of the generatrices and also being positioned outside the coil opposite the first portion. The actuator includes a ferromagnetic core inside the coil and an outer ferromagnetic yoke surrounding the fixed magnet, the coil moving in the air gap formed between the magnetized semicylindrical portions and the inner core.

摘要： A display module has a two-phase motor which includes a rotor including N pairs of poles magnetized radially, in alternate directions, N being equal to 3 or 5, and a stator part including at least two W-shaped circuits made from radial pole teeth extending inwards from a peripheral closed belt and including a coil on a central leg of the W, the W-shaped circuits being arranged in such a way that when the central tooth of one of the W-shaped circuits is positioned facing a rotor magnetic transition, at least one central tooth of another W-shaped circuit is positioned facing a rotor magnetic pole. The display module additionally includes at least one specific mechanical interaction between the rotor and the stator, such as angular friction at a force that is substantially constant depending on the speed of the rotor relative to the stator.
