ABSTRACT:
Rigid support for the rotor winding of a superconductive A.C. generator is achieved by combining a plurality of modular racetrack-shaped sections to form the winding. Each section is separately supported to withstand the centrifugal forces and load forces on the winding during operation. The windings and support members are machined in close tolerance, and the support member material is selected so that differential thermal contraction during cooldown results in an interference fit and compression at the winding-support interface.
