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.
