The objective of this exploratory development program was the completion of the superconducting generator investigations initiated under previous contracts, and culminating with the fabrication and evaluation of a 50 kva laboratory model to verify the generator performance potential predicted by such investigations. The design and fabrication effort of the laboratory model superconducting generator was divided into three major areas. First, an electrical phase provided for the field and armature components from an electrical viewpoint. Second, a heat transfer phase provided for the removal of heat generated by the loss mechanisms of the generator. Third, a mechanical phase provided and maintained the environment package required by superconductors. The completed generator was tested to demonstrate a capability of power generation. A one megawatt generator design is presented based on the experience gained on the design and test of the 50 kva generator.
