ABSTRACT:
This invention relate to a structure for supporting a power lead connected to a superconductive field coil and refrigerant supply and discharge pipes in the hollow shaft of the superconductive rotor. A plurality of spacers for holding the power lead and the refrigerant supply and discharge pipes are fitted in a supporting sleeve, and fixed from the outer peripheral side of the supporting sleeve, the supporting sleeve itself being fixed in the cavity of the hollow shaft. Since the fixing work can be made from the outer peripheral side by means of the structure stated above, it is possible to fix the leads and pipes to the inside of the shaft easily and rigidly, and to avoid the generation of vibration so as to prevent serious damage to the stability of the superconductive state of the rotor.
