An apparatus is disclosed for extracting electrical and mechanical energy from stored magnetic energy. The apparatus includes an axial flow turbine defined by a body having an increased magnetic density from a first exterior edge along a surface of the body to a second exterior edge. Also included is a magnetic element rotatably operable about the body of the axial flow turbine. The magnetic element is configured to cause increasingly level of the magnetic attraction from the first exterior edge to that of the second exterior edge.

Field of the Disclosure The present disclosure relates generally to the field of electric and motor generator systems that provide a motive force of a motor derived through an attractive force of a magnetic field in a rotor. More particularly, the present disclosure relates in one embodiment to a system for providing an increasing attractive force between a magnetic field of a rotor and a stator.

Description of Related Technology Conventional rotor and stator systems require an electric current applied to a coil to induce a magnetic field in a stator so that the stator interacts with a magnetic field of a rotor. In these systems, combinations of electromagnets and permanent magnets are utilized. A conventional one-phase stepping motor may consist of a rotor having two permanent magnetic poles surrounded by a coil. Upon being energized, the rotor coil forms main stator poles. Auxiliary pole arms are divided into groups.

Within each group, auxiliary poles are arranged at a distance from the rotor that decreases gradually (or in stages) in a direction of rotation of the rotor. In yet another conventional system, magnetic attraction may be created by eccentric mounting of a rotor shaft axis with respect to a stator axis to provide a directed magnetic auxiliary force due to an air gap adjustment between rotor and stator. In still other conventional system, a magnetic force is produced by determined magnetic asymmetries of pole fluxes, e.g., having smaller poles in one or more parts of a stator circumference than that in another or opposite part of the circumference.

Other conventional systems use a magnetic bearing device including a rotor having a number of permanent magnets mounted to a central shaft and connected to a driving shaft of a rotating load and a stator surrounding the rotor with an air gap. In this magnetic bearing device a stator is provided with a number of electromagnets on an inner circumference, which when energized successively, create a rotating magnetic field constituted by attracting polarities created by moving permanent magnets. Other conventional magnetic attraction systems use conductive lap windings that are interleaved with conventional loops in the stator of a motor-generator and a rotor provides magnetic induction lines that, when rotated, cuts across the lap windings and the loops.
