Abstract
IRON OR OTHER FERROMAGNETIC MATERIAL IS UTILIZED IN THE MAGNETIC CIRCUIT OF DYNAMOELECTRIC MACHINES HAVING SUPERCONDUCTIVE FIELD OR EXCITATION WINDINGS. IN DC MACHINES, A STATIONARY SALIENT POLE FIELD STRUCTURE WITH A SUPERCONDUCTIVE MAIN FIELD WINDING IS UTILIZED. AN ARMATURE WINDING IS WOUND ABOUT A SMOOTH ROTOR. IN AC MACHINES, A FERROMAGNETIC STRUCTURE THAT ENCLOSES AND ROTATES WITH A SUPERCONDUCTIVE EXCITATION WINDING IS UTILIZED. THE FERROMAGNETIC STRUCTURE MAY INCLUDE EITHER SALIENT POLES INTERCONNECTED BY FERROMAGNETIC SHUNTS OR A SLOTTED OR TOOTHER ROTOR.
