NON-CONTACT EDDY CURRENT BREAK DEVICE USING PERMANENT MAGNETS METHOD FOR CONTROLLING THEREOF AND BREAK SYSTEM USING THE SAME

摘要

The present invention relates to a non-contact braking device and a braking method capable of preventing generation of noise and dust by using a non-contact type, and capable of controlling the braking force flexibly according to the speed of the vehicle, will be. An apparatus for braking a disc, the apparatus comprising: a magnetic layer having a magnet for generating a magnetic field, the magnetic layer being spaced apart from the disc by a predetermined distance; And a shield layer provided between the disk and the magnetic layer and capable of shielding the magnetic field, wherein a magnetic field generated in a magnet facing the disk is applied to a first area of the disk, Wherein a magnetic field generated in a facing magnet is shielded by the shield layer, the first area is an area facing the magnet among the side areas of the disk, the magnetic field applied to the first area forms an eddy current, The braking force for the disk can be generated by using the eddy currents formed.
