Armature of the MIT-EPRI superconducting generator

This paper is a description of the armature built as part of the second MIT-EPRI experimental superconducting alternator. This armature has several new features, including an integral, non-magnetic and non-conducting structure, an open header cooling system using the same fluid as coolant and as electrical insulation, and a limited voltage gradient winding pattern. These features are described, along with the results of measurements of the electrical and thermal properties of the armature.
