Patent ID: 6841909

Claim:
A magnetic drive system, comprising: a motor-driven assembly connected to a motor shaft, which includes one of: (a) an electrically conductive cylinder having a selected length, and (b) an assembly of at least two permanent magnets in a cylindrical arrangement; and a coupling member which is secured to a machine shaft used to drive a machine, the coupling member including the other of (a) the electrically conductive cylinder arid (b) the assembly of permanent magnets in a cylindrical arrangement, the coupling member being positioned such that the permanent magnets are in magnetic interaction with the conductive cylinder along a longitudinal axis, the permanent magnets producing a magnetic field which results in eddy currents being generated in the electrically conducting cylinder which in turn produce a secondary magnetic field which results in rotation of the coupling member, such that rotation of the motor-driven assembly by a motor operating on the motor shaft results in rotation of the machine shaft and the coupling of power therebetween.
