  • Patent number: 10050511
    Abstract: A magnetic coupling device for communicating continuous rotational or linear motion through a magnetic coupling of magnetic forces communicated from magnets operatively positioned on an oscillation assembly and a rotation assembly in positions sufficiently proximate to form the magnetic coupling. Employed to communicate an output force in a rotational direction from an input linear force communicated from a powered oscillation assembly, the magnetic force of the magnet communicating the force compresses the volume of ellipsoidal-like magnetic fields of the coupling alternately in unlike polar domains, to induce a smooth, blended polar continuity and communicate a continuous 360 degree rotational force to a rotation assembly operatively engaged with the magnetic coupling. The input force may be reversed to induce a continuous linear motion of a reciprocating assembly.
