本文主旨在探討研製一無轉軸角度偵測元件之開關磁阻馬達驅動器。文中將就開關磁阻馬達之結構、數學模式、運動原理及電氣特性加以說明，並且回顧目前現有的轉軸角度偵測方法，接著本論文將針對開關磁阻馬達，設計一全數位化的控速系統，並在此一架構下，利用開關磁阻馬達運轉時之激磁電流特性，配合外部硬體偵測電路及內部的DSP 程式撰寫，以獲得轉軸位置資訊，藉由此一轉子位置資訊進而達到轉速控制之目的，另外從靜止起動問題，仍是無轉軸偵測元件驅動器製作技術的一大主題，文中也將對此一部份有所探討說明。
此外為了縮短系統發展時間及驗證所使用的理論方法，本論文利用Matlab/Simulink建立一模擬系統，不僅可為初期理論發展的依據，也可作為日後實測結果的驗證依據。
