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 direct drive electromagnetic actuator includes a housing and a movable body extended by an actuating head. A resilient member exerts a force on the movable body toward an inoperative position. A coil interacts with the movable body so as to generate a second force on the movable body toward an operative position. The actuator further includes a shock-absorbing block movable with respect to the housing over at least a portion of the travel of the movable body and joined to the resilient member. The shock-absorbing block is compressed when the movable body is in the operative position. The actuator also includes a rigid abutment movable over at least a portion of the travel of the movable body between the inoperative position and the operative position, the rigid abutment coming into contact with a wall secured to the housing when the movable body is in the operative position.

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.
