Abstract

A stator assembly (100) for use in a superconducting generator (10) operated at frequencies up to 10 Hz is disclosed. The stator assembly includes a ferromagnetic stator winding support (102) having a plurality of teeth (112) defining slots (114), the slots configured to receive and support stator windings (130). The stator winding support is formed so that the ratio of the sum of the widths of the slots to the sum of the widths of the teeth and slots is in the range of 0.65 to 0.90.
