| Abstract(E) | Based on issues identified in previous studies, this paper presents design improvements for a high power density motor. High-speed operation, electromagnetic optimization, and cooling enhancement were applied. Design conditions considering mechanical strength and loss were clarified, and electromagnetic and thermal characteristics were improved through redesign of flux, current distribution, and cooling paths. Analytical methods evaluated the influence of each factor on power density. Prototype testing confirmed that power density exceeded 10 kW/kg, demonstrating the effectiveness of the proposed design approach. |
