本論文提供了完整且系統化的評估步驟，使得單面軸向磁場式永磁電動機在線圈電流與速率電勢的雙重操作限制下，達到最佳的推進力與軸向力比值操作目標。根據旋轉磁場理論配合永久磁鐵退磁後縮曲線與等效磁路法，推導出電動機系統精確完整的數學模型，並透過多重參考軸原理與詳盡的數學分析，得知電動機的穩態操作限制與最佳電磁轉矩軌跡，最後再配合三維有限元素分析軟體與統計學驗證出，電動機可以經由適當的控制定子相對應電流來達到最佳推力與軸向力比值。從這些結果即可以提供一個完整且適當可行的控制法則，以實現單面軸向磁場式永磁電動機完整的磁場導向控制，最後應用此完整的驅動控制法則製作出以數位訊號處理器為核心之驅動控制實體電路，以實現電動機之最佳操作效能的目標。

This thesis presents a systematic scheme to determine the optimal propulsive/axial force ratio of a single-sided permanent magnet axial-flux motor (SPMAM) along with its operational constraints on both the winding currents and the speed induced voltages. According to the rotating magnetic field theory with combining the recoil line characteristics of permanent magnet and the equivalent operational magnetic circuits, appropriate projection of the stator currents to achieve an optimal ratio of the machine propulsive/axial forces has been confirmed through detailed three-dimensional finite element analysis (3-D FEA) and numerical studies. From these evaluations, a feasible operational guidance for SPMAM field oriented control (FOC) scheme realizations can be suitably provided. Finally, based on the proposed optimal scheme, a DSP-based drive system has been successfully implemented, and the desired operational strategy realization can be achieved.
