A superconducting generator including an armature configured to be rotated via a shaft and a stationary field disposed concentric to and radially outward from the armature. The stationary field including a superconducting field winding and a vacuum vessel having an inner wall of one of a non-magnetic material or a paramagnetic material facing the armature, an opposed outer wall of a ferromagnetic material and a plurality of sidewalls coupling the inner wall and the opposed outer wall. The superconducting field winding is disposed in the vacuum vessel. A wind turbine and method are additionally disclosed. The wind turbine includes a rotor having a plurality of blades. The wind turbine further includes a shaft coupled to the rotor. Moreover, the wind turbine includes the superconducting generator coupled to the rotor via the shaft.
