傳統式的風扇皆以馬達與扇葉組合而成，在設計上馬達與扇葉為分開設計，因此效率、功率密度無法有效的提升且風扇較難實現微小化。本研究以永磁磁通切換式馬達(Flux-switching Permanent Magnet Motor, FSPM)為基礎，因永磁磁通切換式馬達磁鐵與繞線皆位於馬達定子，轉子以單一種軟磁材料組成，因此轉子結構強健，適合將轉子結合軸流式風扇扇葉翼型，並達成一體式設計。本文從傳統式的永磁磁通切換式馬達設計出發，最後結合扇葉與馬達達成一體式設計，並利用有限元素分析軟體進行電磁場與流場的模擬與驗證。最後利用軟磁複合材料(Soft Magnetic Composites, SMC)，以選擇性雷射熔融3-D列印實現與驗證本研究所設計之一體式馬達。

Traditional fans are usually consisted of impeller and electric motor, and the design of impeller and electric motor is separate. Therefore, the efficiency and power density can’t be enhanced effectively and hard to miniaturize. The integrated motor in this paper is based on the Flux-switching Permanent Magnet Motor (FSPM) and combine the airfoil-shaped rotor. The winding and permanent magnet of FSPM is on stator and the rotor of FSPM is composed by single soft magnetic material. The simple rotor shape and robust rotor are suitable for combining the fan’s impeller. This paper first introduce the design method of the FSPM, and combine the impeller design and FSPM design to achieve the integrated motor. Then using the FEA software to simulate the electromagnetic field and flow field of the integrated motor. Finally, implementing the integrated motor via soft magnetic Composites which formed by the selective laser melting 3D printing and verify the performance and efficiency by the dynamometer.
