First Claim
Patent Images
1. A rotor for a superconductive rotary electric machine, comprising:
- a coil carrying shaft;
a plurality of superconductive magnetic field coil means mounted on said coil carrying shaft and having coil end portions which are curved along the circumference of an end portion of the coil carrying shaft, said coil end portions being spaced in the direction of the length of said shaft to define gaps between the coil end portions;
electrically insulating padding plate means positioned against the side surfaces of said coil end portions on opposite sides of said gaps; and
electrically insulating filler means filling the remainder of said gaps between said padding plate means, said filler means being a pair of filler portions which have a cross-sectional shape of complementary wedges and filling the space in each gap between the padding plate means.

Abstract
The present invention consists in that insulating fillers on the sides of superconductive field coils disposed on a coil-carrying shaft in the rotor of a superconductive rotary electric machine are separated into padding plates mounted so as to cover all the sides of the superconductive field coils, and the other portions, thereby to prevent the damage of the insulation between the turns of the field coils and to firmly fix the field coils.
