中文摘要 由於感應馬達具備低成本與結構簡單之優點,因此廣泛地應用於工業之中,然而因其運轉時產生的滑差與轉子銅損,導致馬達效率受到限制。自起動式永磁馬達轉子不但具有感應馬達之鼠籠繞組結構,且在內部嵌入永久磁鐵,使其擁有同步運轉能力與高效率之特性,適合取代感應馬達以達到節能的訴求。
本研究以感應轉矩與煞車轉矩方程式之推導為基礎,討論各項參數對自起動式永磁馬達暫態與穩態特性之影響,並利用有限元素分析軟體(Ansoft EM)進行模擬驗證。最後針對不同的轉子設計類型進行同步化與負載能力之模擬與比較,並選輸出特性較佳之設計,套入一市售1 HP感應馬達,模擬嵌入永久磁鐵後效率改善程度,以作為自起動式永磁馬達設計之重要參考依據。
英文摘要 Induction motors (IMs) have been wildly applied in the industry because of the low manufacturing cost and the simple structure. However, the existence of slip and rotor copper losses will lower the motor efficiency. The structure of Line Start Permanent Magnet Motors (LSPMMs) is similar to IMs, with the permanent magnets inserted in the rotor. Under the synchronous operation, it can provide higher efficiency and be the attractive alternative to the IMs to save electric energy.

In the thesis, the equations of cage torque and braking torque are derived to realize the influence of the design parameters, such as input voltage and magnet remanence, at the transient and steady state based on finite element analysis (FEA). In addition, synchronization and loading capability of different rotor designs are simulated to compare the characteristics. Finally, the design with the best performance is introduced to a produced 1HP IM and the improved efficiency is calculated by FEA method. Overall, this thesis provides levant benchmark for LSPMMs design.
