Abstract

A magnetic coupling device has an electroconductive rotor (15) presenting a band (16, 17) of electroconductive material and has a magnet rotor (14) with permanent magnets (26) which are slide-mounted to move radially outward responsive to centrifugal force in opposition to a spring (40) bias. When the magnet rotor is stationary the magnets are radially inward of the orbit of the electroconductive band, and when the magnets have moved outwardly when the magnet rotor is rotating, the magnets are spaced by an air gap from the electroconductive band so that eddy currents are induced in the band resulting in coupling of the rotors. The electroconductive rotor preferably has two such bands (16, 17) positioned on opposite sides of the magnet rotor. The rotors may have sheaves mounted thereon.
