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.

摘要： A linear electromagnetic actuator has a stroke c, with at least one stable position in one of the ends of the stroke, and includes: an armature made of a soft magnetic material, the armature being movable in an axial direction Y and having a length Hm in the direction Y, the armature having a symmetrical shape at the axis Y, and a stationary stator yoke made of a soft magnetic material and holding at least one electric coil. The actuator also includes at least one stationary permanent magnet that is magnetized along a transverse axis X perpendicular to the direction Y. The magnet is transversely placed between the movable armature and the electric coil. The magnet has a length Ha in the direction Y. The stationary yoke and the movable armature define therebetween at least one axial air gap. Ha+c is of the order of magnitude of Hm. The length Hm is such that 0.9×(Ha+c)
