ABSTRACT:
The rotor of a superconductive rotary electric machine has a coil-carrying shaft carrying superconductive field coils. A plurality of axially running parallel grooves and a pair of annular circumferentially running indentations, each of which is connected to one end of each of the grooves, are formed on the outer surface of the coil-carrying shaft. The axially and circumferentially running portions of the field coils are accommodated in the grooves and indentations respectively, and the spaces left by the circumferentially running portions of the field coils in the indentations are filled by electrically insulating fillers. Further, a plurality of wedges are fitted into the grooves above the axially running portions of the field coils, while a pair of sleeves are fitted around the coil-carrying shaft over the indentations, each of the sleeves being fitted around the coil-carrying shaft only at one end thereof which is situated farther from the central portion of the coil-carrying shaft than the other end thereof. Rings for preventing the slippage of the sleeves are interposed between the portions of the surfaces of the sleeves and the coil-carrying shaft which are fitted together.
