Electromagnetic eddy current damper for sliding doors and windows

An electromagnetic eddy current damper for sliding doors and windows is characterized in that one end of a connecting rod is fixedly connected with a roller; a magnet penetrated by the connecting rod is arranged below the roller; the other end of the connecting rod is fixedly connected with a fixing plate; a nonmagnetic metal pipe body sleeves the connecting rod; the connecting rod connected with the magnet can move in the pipe body; pipe clamps are fixedly connected outside the pipe body; the magnet is cylindrical; holes are formed in the fixing plate; a sticking material is arranged on one surface of the fixing plate; holes are formed in the pipe clamps; a sticking material is arranged on contact surfaces of the pipe clamps. According to Faraday's law of electromagnetic induction (E=-N (delta phi/deltat), E is the change of magnetic flux, delta t is the used time and N is the number of turns of a coil), the magnetic flux changes to produce an induced electromotive force in a conductor, and if the conductor is closed, induced current can be produced.
