中文摘要
本論文旨在建立一台應用太陽熱能發電的機械電磁能量轉換機構,並透過電機設計流程與完整的磁路原理進行開發,以設計出往復運行的管狀線性發電機。在此電機結構的設計上,其定子部份將採用無溝槽式(Slotless)的架構配合三相環形集中式繞線的方式設計,而動子的部份將採用兩段式Halbach陣列磁環的特殊排列方式設計,以完成管狀線性發電機的開發。我們將透過等效磁路法進行磁路分析並估算磁場數值,以及三維有限元素法模擬計算出數據來驗證磁路估算的合理性。最後則是在發電機穩態的條件下評估此電機的操作特性,以約略掌握所設計電機之性能。
Abstract
The objective of this thesis is to establish an electromagnetic energy conversion mechanism that is suitable for electric power generation from solar thermal energy. Based on the generator design and thorough electromagnetic path design, a tubular linear generator system design will be proposed. The stator armature with three-phase concentrated windings mounted on a slotless structure is targeted to be implemented for this structure of the generator design, and a special designed of two-segmental Halbach permanent magnet array will be installed on the mover to fulfill the desired tubular linear generator construction. From detailed magnetic equivalent circuit (MEC) analysis and three-dimensional finite element analyses, the feasibility and applicability of the proposed machine system concepts will be verified. Finally, the steady-state operational characteristic of this generator have been estimated cinfirm the design objectives.
