使用人力之自行車發電機之研究

中文摘要在本篇論文中，我們將提出一些關於人力腳踏車發電機的研究，在實驗中，能量的來源將是旋轉運動中的輪胎。在理想的狀態下，實驗的模組將以不改變腳踏車的結構為原則。而本篇論文中運用的基本理論為法拉第定律，其為一個隨著時間變化之磁場產生感應電場，而將電能收集起來即成為一個發電機。而在本篇論文中，我們首先探討利用電磁鐵來取代傳統的永磁性磁鐵。我們將此模式稱為「free mode」，其原因為永磁性磁鐵雖然易於使用以及設定，但對使用者而言卻缺少了使用上的彈性。其次，我們將設計一個新的架構，它將會改善發電機中磁路的效能，進而提高整體發電機的效率。最後，我們提出一個模組化的設計，可以讓使用者自由選擇期負載。本篇論文的貢獻可分三項來作敘述。第一，降低成本。我們選擇使用廉價的材料，但卻透過磁路的設計，避免整體性能產生大幅的衰退。第二，方便性。在本篇論文中所提出的幾個負載模式，將可視自行車騎者體力與路面坡度的不同做發電量的選擇。第三，高效率。我們所提出的新架構將會對磁場的使用有相當效率上的改善。最後，我們相信在未來綠色能源的研究將會如雨後春筍般不斷的發表出來，這也將逐步減少人類對於地球的汙染，更加的盡好人類身為地球管理者的職分。

In this thesis, we address on the research of the bicycle electric generator which is powered by human energy. The energy source comes from wheel rotating. For ideal condition, the original wheel structure should not be changed. However, there will be some structure modification in our proposed design. The principle of the bicycle electric generator is the Faraday’s Law of Induction. A rotating device with magnets will cause time-variant magnetic field. The coil of generator mode is transfer magnetic field energy to electric energy. In this thesis, we will first discuss how to use the electric magnet to replace permanent magnet. We call this mode as free mode, because the permanent magnet is easy to set up, but inconvenient when the rider does not want to generator electricity. Secondly, we designed a new electric generator structure for the bicycle, it will be more effective than the previous design. Thirdly, we propose a module for electric generator that can select the load they want. In the final of this thesis, we will discuss about the magnetic circuit analysis, and use the model to simulate the human-power bicycle generator. The contributions of our works are as follows: 1. More Cheaper Electric Generator: We utilize the as possible as cheaper part to built the model, but does not decrease the effective. 2. Convenience for Users: We offer many modes to fit many cases, therefore it could easy to set up. 3. More Effective: We design a new combine to produce max magnetic field. Finally, we believed the Green Energy will be more popular than before, and we should try the development of related terms will reduce the earth pollution.
