摘要


近幾年在全球工業快速的發展下,造成環境污染與能源不足的問題日益增長,因此再生能源變成現今社會發展的主要趨勢,而風力發電為再生能源發展重點之一,其裝設已愈來愈普及。 本論文在對一小容量2kW低轉速的外轉子軸向磁通永磁風力發電機進行設計與探討,並且比較集中繞組法和分布式繞組法兩者在軸向磁通永磁風力發電機中的性能。定子繞組部分採用無槽無鐵芯式的設計,可確實達到低啟動扭力、降低頓轉扭矩、減少磁通漣波等損耗。應用直接驅動的方法,傳動不需經過齒輪箱傳動器,使發電機機有效率高、維修費用低、投資報酬率高等優點。 最後實作出一利用集中繞組法且容量為2kW的風力發電機,並對於不同繞組法進行實驗結果和性能的比較與探討。

In recent years, due to the rapid development of global industrialization, environmental pollution and energy shortages become major problems. For remedy these problems, the development of renewable energy is a major choice. Wind power is one of the most important renewable energy sources. So the installation of wind power systems are getting more popular. The purpose of this research is to design a small scale and low speed Axial Flux Permanent Magnet (AFPM) wind turbine generator. This thesis presents a performance comparison on concentrated and distributed windings for an AFPM wind turbine generator. In this design, the stator is slotless and coreless. It can achieved low starting torque, low cogging torque, and low flux ripple, and use direct drive method to eliminate the gearbox. So the wind turbine generator can have the advantages of high efficiency, low maintain cost, and high investment return. Finally, the 2kW wind turbine generator with concentrated windings is built, and results and performances are compared and explored with those of distributed of windings.
