  • System and method for providing coil retention in the rotor windings of a high speed generator
    Patent number: 7015616
    Abstract: A coil retention system for a rotor of a high speed electrical generator, such as an aircraft generator, that uses compliant material to fill variable dimension voids and/or gaps in the coils wound around the rotor of an electrical machine. During processing of the rotor and coil retention system, the compliant material hardens and is able to withstand the centrifugal loads imposed by, and environmental conditions within, the high speed generator.
    Type: Grant
