Abstract :
A variety of topologies have been studied for superconducting generators. The superconducting generators constructed over the past 40 years using low temperature superconductors were built with iron located only in the stator core. The performance characteristics of HTS has led to the consideration of topologies with iron in the center of the rotor inside the field winding, iron in the rotor pole faces and iron in the armature teeth. As the reluctance of the flux path is decreased, the amount of superconductor is minimized and the forces on the rotor and stator coils are reduced. The impact of this addition of iron on other machine parameters including transient stability following a system fault is addressed in this paper
