ABSTRACT:
A rotor for a superconducting rotating electric machine has pre-wound rotor coils housed in longitudinally-extending slots formed in a coil-carrying shaft. Each coil is restrained against circumferential forces by a plurality of rigid restraining members which are inserted between one side of the coil and the side of the slot in which the coil is housed. The restraining members are disposed on top of one another in layers corresponding to the number of layers in the coils. Preferably, they are made of an electrically-insulating material. A plurality of longitudinally-aligned restraining members may be employed for each layer of the coil. The restraining members for each layer may be disposed with gaps left therebetween in the longtudinal direction and packings disposed in the gaps.
