Abstract
A rotor for a superconducting rotating electric machine comprises a cylindrical coil-carrying shaft in which are formed a plurality of parallel coil slots. In the teeth of the shaft adjoining the corners and the arcuate portions of the slots, recesses are formed, and movement prevention means comprising retaining plates, support members, and retaining members which prevent the movement of the wedges and coils in the adjoining coil slots are secured in the recesses by bolts or the like. The provision of the recesses makes it possible to insert previously-wound field coils into the coil slots, and the movement prevention means prevents the movement of the wedges and the coils in the slots. As the movement prevention means is detachable, the inspection and repair of the field coils is facilitated.
