本論文主要目的在於針對抗流型多功能水下遙控載具(Remotely Operated Vehicle, ROV)，研發高性能推進系統。並以無轂環驅式推進器(Ｈubless Rim-driven Thruster)為目標，以系統化方法設計其螺槳及驅動馬達，達成電機控制、流力性能與機械結構之推進器整合設計。本論文利用螺槳升力線理論設計螺槳幾何，並以磁路理論設計無刷直流馬達結構，藉由疊代整合上述兩者，以求得最佳化設計。此設計結果輔以流場有限元素軟體Star-CD及電磁場有限元素軟體ANSOFT Maxwell模擬分析。最後進行無轂環驅式推進器原型機之實測，以驗證所設計結果。
　　無轂環驅式推進器設計目標為：當輸入電壓310Ｖ，推進器轉速可達到2000rpm，並在船速2.06m/s時，整體推進器輸出推力266N；而馬達設計規格為：在上述轉速下，可輸出功率2.5kW、輸出轉矩13.9 N-m之三相16極15槽無刷直流馬達。
整體而言，本研究建立一套完整有效之無轂環驅推進器研發流程，亦將螺槳幾何、馬達細部尺寸及推進器組件實體機構化，以實驗量測螺槳性能及馬達性能，量測結果符合推進器整合理論設計，達成推進器整合設計研發之目的。

　　This thesis presents an integrated design and realization of a hubless rim-driven thruster for remotely operated vehicle (ROV). The systematic design process considers the integration of propeller design, hydrodynamics analysis, motor design/analysis and structure design. The design of the propeller employs the lifting line theory while that of the motor applies the magnetic circuit theory. Optimum design of the thruster can be achieved by iteration of the above two design algorithms. The finite element packages, Star-CD and ANSOFT Maxwell, are respectively used for simulation of hydrodynamics and electromagnetics for the thruster. Finally, a prototype is tested to verify the design.
　　The design target is listed as follows. The thruster can produce a thrust of 266N at 2000 rpm with an input voltage of 310 V and an inflow 2.06 m/s. The torque required for that condition is 13.9 N-m. According to the propeller design result, the motor with three phases, 16 poles, and 15 slots is designed to have a rated output power of 2.5kW to satisfy the torque and speed required for the propeller.
　　Overall, this thesis had successfully constructed an integrated design process for hubless rim-driven thrusters. The experiment has also verified the design.
