Abstract
An auxiliary field winding for a superconductive AC electrical machine. The auxiliary field winding is adapted to provide a controlled and rapidly varying magnetic field to an armature winding in addition to that produced by the main field winding for improving the dynamic stability of the machine. The main field winding is superconductive and is adapted to provide a substantially steady-state magnetic field to the armature. The two windings permit the machine to rapidly accommodate changes in the load made on the machine during operation.
