中文摘要
本研究探討個人動力輔具裝置未來發展之可能需求,提出可直接應用於行動輔助裝置上之結合軸向耦合外環式磁齒輪與電動機結構,並提供系統化的設計流程。此結構藉由磁性齒輪作為能量傳遞的媒介,可降低機械能量間轉換的損失並將裝置尺寸最小化。此系統不需使用額外的機械轉換裝置轉換電功率並可提供較大之輸出扭矩。本研究根據電磁等效電路概念建立數值化磁路模型用以獲得初步分析同步電動機和磁齒輪之電磁特性,求得系統之初步參數並配合三維有限元素分析其動態特性。
Abstract
This thesis investigates a novel structure that is possible for future personal mobile assistive devices application. To minimize the size of the device, a systematic scheme is proposed. From the outer annular-arranged transverse-flux magnetic gears set and the permanent magnet synchronous motor, the input electric power can be converted directly to supply larger output mechanical torque without additional mechanical devices. The preliminary parameters and electromagnetic properties of the device can be roughly estimated by the numerical models based on the magnetic circuit theory. Furthermore, three-dimensional finite element analysis is adopted to supply detailed system dynamic characteristics for validation.
