A rotor and a method of constructing a rotor are disclosed. The rotor includes a hub that is capable of being supported by a shaft that extends along an axis, a plurality of laminations, and a plurality of wire windings supported by the plurality of laminations. The hub includes an inner structure configured to support the hub relative to the shaft, an outer structure that supports the laminations, and an intermediate structure that is coupled to the inner and outer structures and supports the inner and outer structures relative to one another.

1. A rotor comprising:a hub configured to be supported by a shalt that extends along an axis, the hub including:an inner structure configured to support the hub relative to the shaft;an outer structure including a first cylindrical portion having a first outer diameter, and an outer cylindrical portion coupled to the first cylindrical portion and having a second outer diameter that is greater than the first outer diameter; andan intermediate structure that is coupled to the inner structure and the outer structure and supports the inner structure and the outer structure relative to one another;a plurality of laminations supported by the outer structure;a plurality of wire windings supported by the plurality of laminations; anda balancing ring disposed around the outer structure first cylindrical portion, the balancing ring having a third outer diameter that is substantially equivalent to the second outer diameter, whereby the first cylindrical portion is axially balanced. 2. The rotor of claim 1, wherein the inner structure includes a cylindrical cavity capable of receiving the shaft. 3. The rotor of claim 1, further comprising a pair of insulating rings, wherein a first of the pair of insulating rings is positioned on a first side of the plurality of laminations and a second of the pair of insulating rings is positioned on a second side of the plurality of laminations. 4. The rotor of claim 3, wherein the pair of insulating rings and the plurality of laminations are positioned around the first cylindrical portion, and the first of the pair of insulating rings abuts the second cylindrical portion. 5. The rotor of claim 1, wherein both the outer cylindrical portion and the balancing ring include a plurality of orifices that are capable of holding material to affect a balance of the rotor. 6. The rotor of claim 1, wherein the hub is made of a material selected from the group consisting of steel, titanium and high-strength aluminum. 7. The rotor of claim 1, wherein the plurality of laminations is shrunk fit onto the hub, and wherein the hub is capable of being shrunk fit onto the shaft. 8. The rotor of claim 1, wherein each of the laminations has a plurality of teeth and a plurality of cut-outs. 9. The rotor of claim 1, wherein at least one of the inner structure, the outer structure and the intermediate structure of the hub is manufactured to have a thickness, as measured parallel to the axis, within a tolerance of plus or minus three-thousandths of an inch relative to a prescribed thickness. 10. The rotor of claim 1, wherein the intermediate structure includes a plurality of spokes coupling the inner structure to the outer structure. 11. The rotor of claim 10, wherein the plurality of spokes, the inner structure and the outer structure define a plurality of internal cavities within the hub. 12. The rotor of claim 11, further comprising a plurality of terminals on the outer structure of the hub, at which can be affixed a plurality of circuits that extend axially through at least one of the internal cavities. 13. The rotor of claim 12, wherein the hub further includes a plurality of channels within at least one of the inner structure and the outer structure that are capable of conducting fluid. 14. The rotor of claim 13, wherein the fluid is at least one of a lubricant and a coolant, wherein the fluid is sprayed our of orifices toward the plurality of circuits, and wherein the fluid originates from the shaft. 15. The rotor of claim 1, wherein the rotor is an exciter rotor for implementation in a generator assembly. 16. For implementation in a high-speed generator rotor, a hub comprising:an inner structure configured to support the hub relative to a shaftan outer structure configured to support a plurality of laminations, the outer structure including a first cylindrical portion having a first outer diameter, and an outer cylindrical portion coupled to the first cylindrical portion and having a second outer diameter that is greate r than the first outer diameter;an intermediate structure that is coupled to the inner structure and the outer structure and supports the inner structure and the outer structure relative to one another, wherein the intermediate structure defines a plurality of cavities within the hub; anda balancing ring disposed around the outer structure first cylindrical portion, the balancing ring having a third outer diameter that is substantially equivalent to the second outer diameter, whereby the first cylindrical portion is axially balanced. 17 .The hub of claim 16, wherein at least the outer structure further includes a plurality of channels and orifices for conducting and spraying fluid.
