Abstract

A swashplate system includes a rotating outer ring and a non-rotating inner ring, the rotating outer ring being adapted to carry a coil of wire and the non-rotating inner ring being adapted to carry a first and a second magnet. The first and second magnets create a magnetic field and an electrical current is created as the coil of wire passes through the magnetic field as the rotating outer ring rotates.

Claims (45)

1. A swashplate system, comprising:

an outer rotating ring;

an inner non-rotating ring having a top surface; and

an alternator subsystem, having:

a first non-rotating magnet member having a first magnet, the first non-rotating magnet member being operably associated with the inner non-rotating ring;

a second non-rotating magnet member having a second magnet, the second non-rotating magnet member being operably associated with the inner non-rotating ring;

a winding member having a coil of wire, the winding member being operably associated with the outer rotating ring, the winding member being configured to pass between the first non-rotating member and the second non-rotating member; and

a bearing guide operably associated with the inner non-rotating ring;

wherein the first non-rotating magnet member and the second magnet member securely fasten to the bearing guide via an attachment means;

wherein the first magnet and the second magnet are selectively positioned to create a magnetic field therebetween; and

wherein, as the rotating ring rotates, the coil of wire passes through the magnetic field, which in turn creates an electrical current within the coil of wire.

2. The swashplate system of claim 1 , further comprising:

a rectifier carried by the winding member;

wherein the rectifier is adapted to rectify the electrical current.

3. The swashplate system of claim 1 , further comprising:

a metallic plate attached to a surface of the first non-rotating magnet member and disposed between the surface of the first non-rotating magnet member and a surface of the first magnet.

4. The swashplate system of claim 1 , wherein the first non-rotating magnet member comprises:

a base having a surface;

wherein the surface of the base is oriented relatively parallel to the top surface of the surface of the inner non-rotating ring.

5. The swashplate system of claim 4 , the first non-rotating magnet member further comprising:

an outer ring protruding from the surface of the base; and

an inner structure protruding from the surface of the base;

wherein the outer ring and the inner structure securely support the magnet in a relatively fixed position.

6. A swashplate system, comprising:

an outer rotating ring adapted to carry a coil of wire;

an inner non-rotating ring adapted to carry a first magnet;

a structure operably associated with the inner non-rotating ring and adapted to carry a second magnet; and

a bearing guide operably associated with the inner non-rotating ring;

wherein the first non-rotating magnet member and the second magnet member securely fasten to the bearing guide via an attachment means;

wherein the coil of wire is configured to pass between the inner non-rotating ring and the structure;

wherein the first magnet and the second magnet are selectively positioned to create a magnetic field therebetween; and

wherein the coil of wire passes through the magnetic field, which in turn creates an electrical current within the coil of wire.

7. The swashplate system of claim 6 , further comprising:

a rectifier carried by the outer rotating ring;

wherein the rectifier is adapted to rectify the electrical current.

8. A method to create an electrical current with a swashplate system, the swashplate system having an outer rotating ring and an inner non-rotating ring, the method comprising:

creating a magnetic field with a first magnet and a second magnet operably associated with the non-rotating ring;

providing a coil of wire operably associated with the outer rotating ring;

securing the non-rotating ring and the rotating ring to a bearing guide;

rotating the rotating ring; and

creating the electrical current within a coil of wire by passing the coil of wire through the first magnet and the second magnet that create the magnetic field as the rotating ring rotates.

9. The method of claim 8 , further comprising:

rectifying the electrical current with a rectifier.

10. The method of claim 8 , further comprising:

channeling the electrical current to an electrical system conductively coupled to the coil of wire.
