Abstract
An improved rotor for a superconducting rotating electric machine has the arcuate portions and the corners of superconducting field coils housed in circumferentially-extending coil slots of a coil-carrying shaft. Retaining rings which are shrink-fit on the coil-carrying shaft over the circumferentially-extending slots restrains the arcuate portions and the corners of the coils against centrifugal forces. Retaining members are disposed between adjacent coils and are rigidly secured by connectors to the bottom surface of the circumferentially-extending slots by bolts or the like. The retaining members completely fill the spaces between adjacent coils and prevent the movement of the arcuate portions and corners of the field coils. Preferably, the retaining members are made of the same material as the coil-carrying shaft or of titanium or a titanium alloy.
