摘要(中)

本研究設計出一種微型發電機，採用軸向磁化的環形磁鐵作為定子，側邊的PCB線圈作為轉子，在旋轉激發下感應發電。其中為了決定關鍵尺寸，利用理論與模擬數值做為參考依據，優化相關發電參數，包含線圈之匝數、層數與磁鐵厚度等，並使用特殊設計方式完成多層線圈連接，透過內外模型的零件與機構配合，達到尺寸約直徑30 mm、長度20 mm之發電機，實驗在3000 rpm 的轉速下，實現約24 Vpp的感應電壓，在負載為250 Ω時，達到最大功率81 mW，接著利用整流濾波電路測試由交流電轉換直流電的效果，最終將發電機作為感測器的供電來源。

摘要(英)

In this study, a generator is designed, which uses an axially magnetized ring magnet as the stator, and PCB coils on each side as the rotor. The generator can generate electricity inductively under the rotating drive source. To determine the critical dimensions, the theoretical and simulated values are used as a reference to optimize the relevant power generation parameters, including the number of turns, the number of layers, and the thickness. A specific method is used to complete the multi-layer coil connection. Assemble with the external model mechanism to achieve the generator, its diameter is about 30 mm, and its length of 20 mm. In the experiment, at a speed of 3000 rpm, a generation achieved about 24 Vpp, and the maximum power is 81 mW when the load is 250 Ω. Finally, a generator is used as a power source for a sensor.
