MAGNETIC DRIVE ASSEMBLIES

摘要

An apparatus for inducing drive, the apparatus comprising at least one drive element having at least one drive face; at least one driven disc having at least one driven face; the at least one-driven disc being rotatable about an axis relative to the or each drive element; the or respective ones of the drive face and the driven face being positioned such that they are opposed to one another and spaced apart in the direction of the axis of rotation; relative rotation of the at least one driven disc being effected by repulsive or attractive magnetic forces between the at least one driven face and the at least one drive face. Various embodiments are disclosed including a magnetic coupling for rotating shafts, a linear actuator comprising levitation magnets mounted on rails and drive magnets mounted on a wheel suitable for use in a sliding door, a magnetic belt conveyor comprising magnets mounted on a endless belt, rollers and supporting frame.
