本論文旨在研究中國鋼鐵公司煉焦場導焦車驅動用感應馬達之暫態及穩態特性。在感應馬達基本特性分析上，電機之參數及使用模型的適當與否，對系統的特性研究相當重要。本文除了使用交直軸感應電機等效電路模型探討穩態特性外，並採用a-b-c軸三相感應電機模型探討感應電機在本研究系統下之三相暫態及動態特性。
　　本文中將採用四組小型獨立變頻器控制四組獨立感應馬達以及使用單一較大型變頻器控制四組並聯運轉感應馬達，分別針對感應馬達的輸出特性做比較分析。由系統實際現場量測與計算機模擬之輔助對照，可驗證本系統所推導之感應電機等效電路模型與參數的可用性及可行性。

　　This thesis investigates the characteristics of induction motors (IMs) for driving coke oven plant’s coke transfer cars of China Steel Corporation (CSC). The employed mathematical model and parameters of the studied IMs are very important for performance analyses of the studied system. The induction machine’s q-d axis and a-b-c axis equivalent-circuit models are respectively utilized to analyze both transient and dynamic behaviors of the studied IMs.
　　This thesis discusses and compares the output performance of four independent IMs driven by four independent small frequency converters and four parallel-operated IMs driven by a large frequency converter. By comparing field measured results and computer simulated outcomes, it can be confirmed that the employed model and parameters for the studied IMs are proper and feasible.
