| Abstract(E) | This paper presents a detailed evaluation of the prototype motor designed in Paper 4. Output characteristics, efficiency, temperature distribution, and loss behavior at high-speed operation were investigated. Comparison with analytical results enabled quantitative evaluation of the contributions of electromagnetic design and cooling structure. In addition, interactions among design factors were analyzed to identify dominant factors governing performance. Finally, design constraints and remaining challenges were clarified, providing insights for further improvement of high power density motor design. |
