近年來通訊相關產業蓬勃發展，對高功率電子元件需求隨之提高，而熱流密度也不斷增加，因此散熱技術成為影響設備可靠性以及壽命的關鍵之一。開發高性能環路熱管(Loop Heat Pipe, LHP)可有效解決高功率固態元件熱集中及系統散熱問題。運用LHP系統，可在系統中加入幫浦馬達等裝置驅動流體，以增加氣、液體循環速度，大幅提升散熱功率。
　　本文針對適用整合於環路熱管之游標式永磁同步電動機(Permanent Magnet Synchronous Vernier Motor, PMSVM)進行設計與性能分析，加入套管建立密閉空間使液體穩定流動。設計一低轉速、高轉矩密度之電動機，並在符合目標轉矩及電壓的條件下，比較表面型永磁同步電機與游標式永磁同步電機的差異，同時改變定、轉子結構並進行分析，以改善轉矩漣波、效率優化等。最後評估端部大小與輸出性能後，提出一結合密閉套管之游標式永磁電機適用於環路熱管之設計。

In recent years, the communication-related industries have developed vigorously. The demand for high-power electronic components has increased, and so has the heat flow density. Therefore, heat dissipation technology has become one of the keys to affect reliability and life of the equipment. The development of high-performance loop heat pipes (LHP) can effectively solve the problems of heat concentration of high-power solid-state components and system heat dissipation. With the LHP system, pump motors and other devices can be added to the system to drive fluid to increase the circulation speed of air and liquid, which greatly increases the heat dissipation power.
This thesis aims at the design and performance analysis of a permanent magnet synchronous motor (PMSVM) integrated into the loop heat pipe with the casing added to create a closed space to make the liquid flow stably. This thesis designs a low-speed, high-torque-density motor, compares the difference between the surface type permanent magnet synchronous motor and the vernier type permanent magnet synchronous motor under the condition of meeting the target torque and voltage and then changes the stator and rotor structure and proceeds with the analysis to improve torque ripple, efficiency optimization, etc.
Finally, after evaluating the end size and output performance, a vernier permanent magnet motor incorporated into a closed sleeve is proposed for loop heat pipes.
Key words: integrated pump motor, vernier permanent magnet synchronous motor, cogging torque analysis.
