ABSTRACT:
A conductor rotor presents a pair of electroconductive rings spaced apart to receive magnet carrying shoes with permanent magnets to induce eddy currents in the rings and thereby retard rotation of the conductor rotor. The shoes are moved in and out in a controlled manner to move between a retracted brake-off position and an extended brake-on position.
