Abstract
An electromagnetic system for more efficiently utilizing energy wherein an outside power source is utilized to rotate a flywheel to a predetermined velocity. A plurality of armatures mounted on the periphery of the flywheel pass through a plurality of magnetic fields generated by stationary coils mounted at radially spaced locations around the rotating flywheel. The magnetic fields are generated by an electric current from a circuit that is so arranged that the magnetic fields are generated and collapsed in time relationship to the rotary movement of the armatures such that, as the armatures approach the magnetic field, they are drawn toward the center of the magnetic field at which point the magnetic field collapses and is regenerated with a reverse polarity so as to repel the armature from the center of the magnetic field whereby the flywheel rotation is maintained at the desired velocity.
