  • Synchronous electric machine with superconductive field windings
    Patent number: 4577126
    Abstract: A synchronous electrical machine including a fixed superconducting field winding to provide D.C. magnetic field when a D.C. current circulates through the winding. A fixed normally conducting armature is provided with a plurality of spaced-apart disks. Each disk is made from insulating material and is provided with flat windings for circulation of A.C. currents. A plurality of rotor disks is axially interleaved with the disks of the armature. Each rotor disk produces A.C. electromagnetic forces in the flat windings upon rotation of the rotor.
