摘要: | 為了彌補純電動車續航力不足以及能源補充不易等缺點,增程發電型電動車的相關技術已逐漸被開發,最常見的增程發電形式為引擎帶動發電機運轉,該引擎只為帶動發電機而作動、提供發電機穩定的轉速,而後端所連接之發電機則須在定轉速運轉之下擁有高效率、低力矩漣波等良好的電氣輸出性能,對於引擎和發電機兩者而言,固定負荷下的穩態運轉有助於提升整車動力系統的效率、亦能有效降低引擎的廢氣排量,因此增程發電型電動車能夠擁有較佳的燃油經濟性。
本研究結合發電機電氣實驗與有限元素模擬結果,完成有限元素分析應用於電機性能模擬之驗證,之後,即利用有限元素法設計一適用於增程發電系統之微磁阻式永磁發電機。根據發電機設計過程中的相關經驗提出微磁阻式電機參數之設計流程建議,並且針對設計結果進行磁鐵減量之設計改良;同時,本研究也探討了不同型式轉子對於發電機磁石減量結果以及電氣性能之影響。 In order to solve the the lack of car mileage and difficult energy supplement for battery electric vehicle (BEV), range-extender electric vehicle (REEV) has been gradually developed. Most common type of range-extender generator is driven by engine with fixed-speed, and the generator must have efficient electrical performance and low torque ripple. Generator and engine operating at steady state under fixed load will not only improve the efficiency of the vehicle power system but also effectively reduce engine exhaust emissions. Therefore, range-extender electric vehicle have better fuel efficiency. According to the results of machine experiments and numeric, this study verified the application of finite element method in the simulation of the motor electrical performance.Then, this thesis applied the finite element method in range-extender generator development process and presented a suitable design process for ISPM machine moreover improved the permanent magnet reduction design. In addition, the study also discussed the impact of different forms of the rotor for the generator permanent magnet reduction results and electrical properties. |
