高功率行星式發電機構之應用研究

傳統的發電裝置其輸出電壓的大小取決於感應線圈中磁通量對時間的變化量，因此欲增加輸出電壓則需增加磁場大小，感應線圈數目，置入矽鋼片，加裝齒輪箱…等。然而，這些方式卻會造成轉子重量增加，產生磁拉力，因而增加發電機軸承的荷載，使轉子不易驅動，故不利於運用潔淨能源作為其驅動來源，因此如何改善傳統的發電裝置是本研究之目的。本論文提供一種新型的「行星式發電機構」，並將所研製之發電機構應用於各種不同裝置上，經實際測試結果安裝於電動自行車上，其最大輸出功率可達 300 W，輸出電流為 1.2∼1.3 A，而裝置於『緊急備用發電桶』，則最大輸出功率可達46W，輸出電流為0.38A，應用於行星式軸向磁通永磁無鐵芯無刷單相交流發電機構則實際測試結果，在轉速達到最高200rpm時，輸出最大功率約為410W。

The size of the output voltage of traditional power generators depend on the magnetic flux changes in the induction coil over an amount of time, so in order to increase the output voltage one needs to increase the size of the magnetic field, the number of induction coils, add silicon steels, and install gear boxes..etc. However, these methods will cause the rotor weight to increase, resulting in a magnetic pull, thereby increasing the generator bearing load which makes the rotor harder to run, making it a bad choice to use clean energy as its driving source. Therefore how to improve traditional power generating devices is the purpose of this research. This thesis report introduces a newly developed “Planet Style Power Generator”, and applies this generator on a variety of devices. Based on actual testing results using the device on HPEG, the maximum output of the developed HPEG can reach 300W, with the output current being 1.2~1.3A. Using the device on an emergency back up power generator, the maximum output power could reach up to 46W, with a maximum output current of 0.38A.Used on Planetary axial flux a single-phase AC power permanent magnet generator, the greatest successful output is about 410W when the rotating speed reaches the maximum 200 rpm.
