Abstract

A superconducting generator with a normally conducting armature winding is provided with a rotor having a superconducting field winding and a superconducting damper winding with the damper winding on a quadrature axis in relation to the field winding and located radially interior of the field winding to result in minimal spacing of the field winding and the armature winding and still achieving a high degree of fault worthiness.
