應用於機車發電機之外轉子式永磁磁通切換發電機設計

為了解決Yamaha EMF的問題，作者馬碩晟 這樣論述：

本論文利用磁通切換電機的架構來設計一機車發電機，此發電機使用外轉子的結構，不但能夠增加氣隙半徑，而且因為轉子單純由矽鋼片構成，具有強健的結構可以在惡劣的環境運轉。發電機設計時參考目前市面上流通之機車發電機的規格以及外觀限制，並以此來訂定本發電機之規格。另外，為了繞線的方便，本論文提出的發電機選擇六槽的定子結構，在此結構下，選擇7極之轉子具有較佳的性能，但是轉子為奇數時，定、轉子之間會產生相當大的徑向的不平衡力，因此本文也提出利用雙層轉、定子來消除徑向不平衡力的設計。除了以有限元素分析軟體分析設計之外，本文亦實作設計的發電機，測試其性能以驗證設計的正確性。
