1. A rotor for use in a high speed generator, the rotor comprising:

  • a shaft extending axially through the rotor;

    a plurality of rotor poles extending radially away from the shaft, each rotor pole having an end face;

    a plurality of spokes extending radially from a location along the shaft, each spoke radially aligned with, and coupled to, one of the rotor pole end faces;

    a plurality of supports, wherein each one of the supports at least partially surrounds a respective one of the spokes, and includes an inner face positioned proximate its respective spoke, and an outer face;

    a plurality of coils of wire windings, each wrapped around a respective one of the support outer faces and a respective one of the spokes; and

    at least one cap device preventing the wire windings of the coils from moving outward away from the shaft beyond outer radial limits;

    wherein each support is coupled to the at least one cap device, wherein each support extends radially inward along its respective spoke from the at least one cap device to at least a respective inner limit, wherein each support includes at its respective inner limit a respective flange protruding away from the respective spoke, and wherein each flange prevents the wire windings of the respective coil from moving beyond the respective inner limit towards the shaft.
