Abstract
An eddy current brake system with dual use conductive fin includes a linear array of spaced apart permanent magnets 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 is provided for frictionally engaging the 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.
