Abstract

An electromagnetic apparatus has a rotating element acting as a transfer bridge between two active energetic suppliers, the rotating element providing a ferromagnetic core with plural solenoid coils having induced electric energy from external permanent magnets; the core transferring energy by induction to the inner stator's wound active permanent magnet, the energy collector and inductor acting as a generator.

Claims (8)

1. An electromagnetic apparatus comprising: a linear-toroidal ferromagnetic core wound with a plurality of independent, radially oriented, spaced apart, short-circuited solenoid coils; the core fixtured for rotation between permanent magnets located externally and internally on stator supports; the internal permanent magnets providing a south pole sector, a north pole sector and a central portion joining the two pole sectors; and an induction coil wound about the central portion and providing at least one tap.

2. The apparatus of claim 1 wherein the solenoid coils are placed within the core.

3. The apparatus of claim 1 wherein the core is inductively of an opposing pole sense to the internal and external permanent magnets.

4. The apparatus of claim 1 wherein the external and internal permanent magnets are placed with common poles adjacent thereby, by proximity, inducing an opposing pole in the ferromagnetic core.

5. A method of generating electrical current comprising the steps of: rotating a toroidal ferromagnetic core having plural radially oriented and spaced apart solenoid coils between stator permanent magnets external and internal to the core; inducing electric energy from the external and internal permanent magnets in the coils so the coils become electromagnets; transferring energy by induction in the form of electric current flow to an induction coil wound about a central portion of the internal permanent magnets; and placing a load across terminals brought from the induction coil.

6. The method of claim 5 further comprising the step of inducing an opposing pole sense in the solenoid coils relative to the internal and external permanent magnets.

7. A method of operating an electric motor comprising the steps of: providing a pulsed direct current at a selected frequency to terminals external to an induction coil wound about a central portion of an internal permanent magnet and thereby inducing a magnetic field and inducing solenoid function in plural radially oriented and spaced apart solenoid coils wound on a rotatable ferromagnetic core between stator permanent magnets external and internal to the core; the solenoid coils acting to produce a displacement of the core during each pulse resulting in continuous rotation.

8. The method of claim 7 further comprising the step of inducing an opposing pole sense in the solenoid coils relative to the internal and external permanent magnets.
