Wind turbine having superconducting generator and armature for use in the superconducting generator

A wind turbine, comprising:

• a rotor comprising a plurality of blades;
• a shaft coupled to the rotor;
• and
• a superconducting generator coupled to the rotor via the shaft and configured to be operated via the rotor, wherein the superconducting generator comprises:
• a stationary generator field;
• a superconducting field winding disposed on the stationary generator field;
• and
• an armature disposed on a rotor of the superconducting generator concentric to the stationary generator field, the armature providing a rotatable armature field relative to the stationary generator field, wherein the armature comprises:
• an armature winding comprising a plurality of coils, wherein each coil of the plurality of coils is spaced apart from adjacent coils and comprises a first side portion and a second side portion;
• a first electrically insulating winding enclosure;
• a second electrically insulating winding enclosure disposed at a radial distance from the first electrically insulating winding enclosure, wherein the armature winding is disposed between the first electrically insulating winding enclosure and the second electrically insulating winding enclosure;
• an electrically insulating coil side separator disposed between the first side portion and the second side portion of the plurality of coils of the armature winding;
• and
• a plurality of electrically insulating spacers, wherein at least one electrically insulating spacer is disposed between adjacent first side portions, and between adjacent second side portions, and wherein one or more of the plurality of electrically insulating spacers comprise at least one cooling channel configured to facilitate a flow of a cooling fluid therethrough to aid cooling of the armature winding.
