Abstract
The magnetic drive system includes a motor and motor shaft and a motor assembly, the motor assembly including a cylinder of copper. A machine assembly for driving a machine includes a permanent magnet assembly. The motor assembly and the machine assembly are supported relative to each other so that the permanent magnet assembly and the ring of conductive material are in longitudinal juxtaposition so that rotation of the motor shaft results in rotation of the machine shaft through magnetic action.
Claims13
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.

A magnetic drive system, comprising:
- a motor assembly responsive to the action of a motor for rotation thereof;
- a machine assembly, connected to a machine shaft which drives a driven assembly;
- and
- wherein a selected one of a) the motor assembly and b) the machine assembly includes two concentric permanent magnet ring assemblies with a defined space between them extending in the longitudinal direction between the motor assembly and the machine assembly, the other one of a) the motor assembly and b) the machine assembly includes a cylinder of electrically conductive material arranged and configured to fit between and come into a longitudinal relationship for magnetic interaction between the two permanent magnet assemblies and the cylinder, wherein the permanent magnet assemblies produce a magnetic field which results in eddy currents being generated in the cylinder, which in turn produce a secondary magnetic field, which operates such that rotation of the motor driven assembly results in rotation of the machine shaft and coupling of power therebetween.
