An eddy current brake system with dual use conductive fin (40, 60) includes a linear array of spaced apart permanent magnets (16, 18) and a non-magnetic electrically conductive fin. The magnets are mounted with respect to the fin for enabling passage past one another at a distance sufficient to cause eddy currents to be induced resulting in a braking force between the magnets and the fin. A mechanical brake (36, 70) is provided for frictionally engaging t he fin and a surface treatment of the fin and enables the fin to sustain mechanical abuse of friction without effecting a change in the eddy current braking. |
