This paper considers the merits of using a HTS rotor winding in a low-speed high-torque synchronous generator and the possibility of building a small-scale demonstrator to investigate the practicality of building such a machine. Pareto optimization results are presented for both full size and demonstrator size machines with YBCO rotor windings. This optimization used a variation of the Kriging method to reduce the number of FEM models required. A number of design issues and some sensitivity analysis are also discussed.
