An attempt has been made in this work to design, fabricate and performance evaluate a 2 kW permanent magnet synchronous motor operating at 200,000 rpm and at the temperature of both room temperature and 77 K. Structural, thermal and rotordynamic aspects were considered and models were developed on an iterative basis. Prototypes were fabricated and models were validated through experimental results. The PMSM motor/generator prototype was fabricated. At this stage, experimental results were obtained for the test set-up operating at 200,000 rpm and air at room temperature. Models developed were validated comparing to experimental results.
