  • Patent number: 12203523
    Abstract: An active anti-vibration system includes a mounting base having an upper side onto which a motion system is mountable and a lower side, a supporting frame resting on the floor, and active bearings mounted into an active bearings compartment defined by the lower side of the mounting base and an upper side of the supporting frame. Each active bearing includes actuators for imparting counteracting forces to compensate for reactions forces generated by the motion system, when mounted onto the mounting base and operating, to avoid unwanted movements of the mounting base and dampen any residual movements. Each active bearing further includes an upper panel mounted against the lower side of the mounting base, and a lower panel mounted against the upper side of the supporting frame.

  • Patent number: 12154820
    Abstract: A magnetic stopper, for a rotary motion system that includes a base unit and a rotary unit rotatably mounted on the base unit, includes a static part configured to be mounted on the base unit and a rotary arm configured to be mounted on the rotary unit. The static part includes a rotary arm stopping portion configured to receive a distal end portion of the rotary arm, and a movable arrangement including a magnet holder and a mobile magnet mounted on the magnet holder and movable within the rotary arm stopping portion. The rotary arm includes a rotary arm magnet configured to magnetically interact with the mobile magnet when the static part and the rotary part are mounted respectively on the base and rotary units, to prevent excessive movement of the rotary unit when the rotary motion system is operating.

  • Patent number: 11973393
    Abstract: A movable part of a linear motor, having a primary part movable relative to a secondary part, includes a carriage, the primary part, and an interface member for removably connecting the carriage to the primary part. The carriage is configured to fixedly support an object to be moved, such as, for example, a machine part of a machine tool. The carriage includes two opposite lateral sides and a bottom side having an interface member receiving portion including anchoring receiving parts. The carriage interface member is fixedly connected to the primary part and includes anchoring portions mounted on respective anchoring receiving parts of the carriage. Two opposite edge portions of the carriage interface member are aligned and are fixedly connected to a portion of respective opposite lateral sides of the carriage.
