The conventional ultra-high-speed motor (UHSM) has been mostly developed for light load (or low power) applications (e.g., ~100W, 500 kr/min). However, the new mechanical antenna system requires a high-power UHSM. Accordingly, the conventional design

The rare-earth (RE) permanent magnets (PM) have been increasingly adopted in traction motor application. However, the RE PM is expensive, less abundant, and has cost uncertainties due to limited market suppliers. This paper presents a new design of a
