Magnetic levitation system for doors and windows

摘要

A magnetic levitation system for sliding door and window, includes at least a movable module for the lower part of the sliding door and window which includes one or more permanent magnets; several fixed modules for the lower part of the frame of the sliding door and window, which includes one or more electromagnets to produce a variable repulsive magnetic field of the magnetic field of said magnets of the movable module. It has the advantage of eliminating the friction, mechanical wear and noise associated to the sliding, allowing, when deactivated, a greater air and water tightness and terminal and acoustic insulation, allowing the electromagnetic closure or locking of the door and window, increasing the security, and as is a modular system its operation and construction are simpler and more economical.

1. Magnetic levitation system for a sliding door or sliding window, comprising:
a movable module for a lower part of a sliding door or window, the sliding door or window having a movable frame slidable within a fixed frame, the movable module comprising at least one permanent magnet and the movable frame of the door or window; a plurality of fixed modules for the fixed frame, each of the plurality of fixed modules comprising one or more electromagnets for producing a variable magnetic field repulsive of the magnetic field of said magnets of the movable module; at least a clearance sensor, inserted in each fixed module and placed between the movable frame and the fixed frame; at least two electric connectors; at least one electronic control system; and a control unit designed to maintain a predefined clearance between the movable frame and the fixed frame by controlling the power supplied to the two or more electromagnets; wherein the distance between a fixed module and the movable module varies between 1 mm and 10 mm; and wherein the control unit is configured to activate and deactivate the plurality of electromagnets of the plurality of fixed modules on a module by module basis.
