摘要

現今工業時代，人口集中於都市中，運動的空間與時間逐漸減少，所以家庭用運動器材的成為健身運動的主要器材，再加上能源短缺的世界趨勢，發展自發電阻尼控制系統的健身器材則為相關業界的重要研究課題。
傳統自發電健身腳踏車之阻尼系統主要利用發電機的外轉子飛輪作為導磁體，並配合外部電磁鐵作為磁力來源，再以發電機所發出電壓源控制電磁鐵的電流大小，使其對飛輪產生電磁制動，雖然達到自發電阻尼運動效果，並沒有將自發電阻尼效用轉化為電能儲能功用。本文針對傳統自發電健身腳踏車之電磁制動阻尼系統之缺點加以改善，直接以轉矩模式作定電流控制，將人體動能轉成電能儲存於蓄電池，或經由變流器轉成交流電源，提供輕負載所需電源使用，達到更節能減炭效果。最後，藉著負載模擬、數位控制及實作的結果，來驗證其新架構之可行性及效能。

The population has concentrated in the city town after industrial revolution. This change makes the room and time for exercise become much less than before. Thus the fitness products for in-door use become the main equipment for a family. Plus the trend of power source shortage in the whole world. The development of renewable energy or a self-power generating product has come to an importance issue to the fitness industry.
The design of damping system for a traditional self-generating exercise bike is to take the external rotor wheel of generator as a magnetic conductor. To coordinate with external magnet becomes a source of magnetic power. Furthermore, take the voltage source which comes out from generator to control the current amount of magnet. This way effects flywheel to produce the electromagnetic control. Although this reaches the operation result of self-power damping system, it doesn’t turn this result to the electricity power for power storage. The solution to this weak shown in this context is to use torque mode as a current control and turn the dynamic to be electricity. Then reserve the electricity into battery or transform the electricity to be AC current via a transformer for light-load power use to reach the eco effect. Finally, use the result of simulation with the loading, digital control and implementation to verify its feasibility and effectiveness under such new structure.
