A generator comprising a magnetic gear, the magnetic gear comprising a stationary member comprising a set of electromagnets, a first moveable member comprising a set of magnets, and a second moveable member disposed between the first moveable member and the stationary member. The second moveable member comprises a set of core members. The first and second moveable members are magnetically coupled to define a gear ratio therebetween and the electromagnets are operable to control the gear ratio. The stationary member comprises a stator of the generator and the first moveable member comprises an armature of the generator, wherein the armature is arranged to induce an electrical current in a set of generator windings disposed around the stator. The second moveable member comprises an input means arranged to receive a drive force. The gear ratio is variable, such that a variable output speed may be produced for a given input speed.

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.
