A new improved system and method for end turn retention for wires on a generator rotor for use in high speed applications such as in aircraft applications. The rotor includes a shaft, spokes, supports, and wire winding coils, and at least one cap device. The spokes extend radially outwardly from the shaft, and each support is positioned on an associated spoke. Each coil wraps around an associated support and spoke. Each cap device is coupled to an end of its associated spoke to prevent the windings from moving radially outwardly while the rotor spins. Each support is coupled to an associated cap device, and includes at its radially inward edge a flange protruding away from the respective spoke. Because of the flange and the cap device, slack of the wire coil between the flange and the associated cap is taken up.

A new improved system and method for end turn retention for wires on a generator rotor for use in high speed applications such as in aircraft applications. The rotor includes a shaft, spokes, supports, and wire winding coils, and at least one cap device. The spokes extend radially outwardly from the shaft, and each support is positioned on an associated spoke. Each coil wraps around an associated support and spoke. Each cap device is coupled to an end of its associated spoke to prevent the windings from moving radially outwardly while the rotor spins. Each support is coupled to an associated cap device, and includes at its radially inward edge a flange protruding away from the respective spoke. Because of the flange and the cap device, slack of the wire coil between the flange and the associated cap is taken up. od comprising: positioning at least one support on a first one of the spokes, wherein the at least one support includes a flange, an inner face positioned proximate the first spoke, and an outer face;wrapping the wires of the coil around the outer face of the support;providing a cap hat proximate an outer end of the first spoke away from the shaft; andattaching at least one of the cap hat and the support to the first spoke and, if only one of the cap hat and the support is attached to the first spoke, further attaching the cap hat and the support to one another;wherein the flange extends away from the first spoke and prevents movement of the wires of the coil toward the shaft beyond an inner limit, and wherein the cap hat prevents movement of the wires away from the shaft beyond an outer limit.12. The method of claim 11, wherein the cap hat in attached to the spoke, and the cap hat is additionally attached to the support.13. The method of claim 12, wherein the cap hat is attached to the spoke by two bolts, and the cap hat is additionally attached to the support by two additional bolts.14. The method of claim 13, wherein the flange is provided on the support, and wherein the flange provides force to move at least some of the wires of the coil toward the cap hat as the support is attached to tho cap hat by the two additional bolts.15. The method of claim 11, wherein the cap hat and the support are both attached to the spoke.16. The method of claim 11, wherein the additional element is a L-type bracket that includes the flange, wherein the coil includes an inner side and an outer side, wherein the support physically contacts the inner side of the coil, and wherein the L-type bracket is attached to the cap hat so that the bracket extends away from the cap hat toward the shaft on the outer side of the coil.17. The method of claim 11, further comprising:positioning a second support on a second spoke extending radially from the shaft opposite tho first spoke;wrapping wires of a second coil around the outer face of the second support;providing a second cap hat proximate a second outer end of the second spoke away from the shaft;attaching the second cap hat to the second spoke and further attaching the second cap hat and the second support to one another; andproviding a second flange on the second support,wherein the second flange extends away from the second spoke and prevents movement of the wire of the second coil toward the shaft beyond a second inner limit, and wherein the second cap hat prevents movement of the wires of the second coil away from the shaft beyond a second outer limit.
