Braking apparatus eddy current.

Braking apparatus eddy current, comprising: a moveable carriage (44) on at least one rail (48); magnetic means disposed on the carriage (44) for providing a magnetic flux, consisting of said magnetic means in one set (42 and 82) of permanent magnets (180, 182 and 184) and several magnets directors flow (190, 192, 194, 196, 198 and 200) arranged in apertures (202, 204, 206 and 208) located between said spaced apart permanent magnets (180, 182 and 184), orienting said magnets directors flow (180, 182 and 184) to order to provide a polarity of the flow director rotates by about 90 ° or 45 ° to a polarity of the magnetic flux of the separate permanent magnets (180, 182 and 184); electroconductive means (54, 186, 274, 296) arranged in an external curvilinear pattern to the trolley (44) to activate only the magnetic flux provided by the single set (42 and 82) of permanent magnets (180, 182 and 184 ); and means, comprising magnetic means and the conductive means (54, 186, 274 and 296), to allow relative movement between the magnet means and conductive means (54, 186, 274 and 296) to produce currents Foucault conducting means (54, 186, 274 and 296) resulting in a braking force between the magnet means and conductive means (54, 186, 274 and 296), characterized by comprising a means of ferromagnetic support (56 and 72), holding the conductive means (54, 186, 274 and 296) for providing a holding force between the carriage (44) and conductor means (54, 186, 274 and 296).
