Abstract

A flat rotary electric generator includes at least one toroidal coil structure for cutting magnetic lines to induce a current and at least one disc-shaped magnetic pole structure oriented parallel to the helical coil structure. If multiple toroidal coil structures and disc-shaped magnetic coil structures are included, the toroidal coil structures and disc-shaped magnetic coil structures are arranged in alternating manner. The toroidal coil structure and disc-shaped magnetic pole structure are not provided with a permeable material. When either the toroidal coil structures or the at least one disc-shaped magnetic pole structure is rotated by an external force, the toroidal coil structure cuts the magnetic lines passing therethrough to generate an induced current.

Claims

WHAT IS CLAIMED IS:
1. A flat rotary electric generator, comprising: at least one toroidal coil structure, for cutting magnetic lines to induce a current; at least one disc-shaped magnetic pole structure having a plurality of poles of opposite polarity, said poles of opposite polarity facing said disc, and said disc being oriented parallel to the toroidal coil and located on one side thereof, and wherein when either the toroidal coil structure is rotated or the disc-shaped magnetic pole structure is rotated by external force, the toroidal coil structure cuts the magnetic lines passing through the toroidal coil structure to generate an induced current.
2. The flat rotary electric generator according to Claim 1 , wherein the electric generator lacks a magnetically permeable core.
3. The flat rotary electric generator according to claim 1 , wherein the generator comprises a plurality of toroidal coil structures and disc-shaped magnetic pole structures arranged in alternating and parallel manner.
4. The flat rotary electric generator according to claim 1 , wherein the disc-shaped magnetic pole structure includes at least two magnetic poles arranged in sections bounded by radii of the disc-shape, and the sections of the disc-shaped magnetic pole structure each comprise a single N or S pole. -11-
5. The flat rotary electric generator according to claim 1 , wherein the disc-shaped magnetic pole structure sections each comprise at least two poles in series.
6. The flat rotary electric generator according to claim 1 , wherein magnets of the disc-shaped magnetic poles structure comprise discrete structures joined together.
7. The flat rotary electric generator according to claim 1 , wherein the disc-shaped magnetic pole structure comprises a single disc-shaped member magnetized to form alternating poles.
8. The flat rotary electric generator according to claim 1 , wherein the toroidal coil structure is fixed and the disc-shaped magnetic pole structure rotates, and the toroidal coil and the disc-shaped magnetic pole structure are co-axial.
9. The flat rotary electric generator according to claim 1 , wherein the toroidal coil structure rotates and the disc-shaped magnetic pole structure is fixed, and the toroidal coil structure and the disc-shaped magnetic pole structure are co-axial.
10. The flat rotary electric generator according to claim 1 , wherein the external force includes vibration or a swinging force.
14 -12-
11. The flat rotary electric generator according to claim 1 , wherein the toroidal coil structure includes circular windings connected in series.
12. The flat rotary electric generator according to claim 1 , wherein the toroidal coil structure includes non-circular windings connected in series.
13. The flat rotary electric generator according to claim 1 , wherein the toroidal coil structure includes a plurality of stacked windings.
14. The flat rotary electric generator according to claim 1 , wherein the toroidal coil structure includes a plurality of non-stacked windings.
15. The flat rotary electric generator according to claim 1 , wherein the toroidal coil structure includes a plurality of interlaced windings.
16. The flat rotary electric generator according to claim 1 , wherein the toroidal coil structure includes a plurality of non-interlaced windings.
