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. en_US DC.subject 微型發電機 zh_TW DC.subject 優化設計 zh_TW DC.subject 旋轉發電 zh_TW DC.subject Micro generator en_US DC.subject Optimized design en_US DC.subject Rotary power generator en_US DC.title 微型軸向發電機之優化與設計 zh_TW dc.language.iso zh-TW zh-TW DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
