本研究分別探討風扇馬達與橫流式馬達(transverse flux motor)之創新設計，並建立電腦輔助設計流程。風扇馬達研究中採用軟磁複合材料，建立新型3-D定子磁路結構，縮小風扇旋翼葉轂，有效地將空氣帶進中心熱源處，進而讓散熱模組的效率提昇。此一創新結構將原傳統風扇馬達定子體積縮小10%，最後實作並以特性量測，驗證設計之正確性。
在橫流式馬達之創新設計方面，本研究提出軟磁複合材料應用於新型橫流式馬達，轉子部分採用環狀磁石簡化傳統橫流式馬達結構，因此能有效降低製造成本。本研究同時也針對此馬達之3-D磁路結構，提出簡化2-D模型估算馬達主要尺寸，使得設計流程更具效率，並經由模擬與實測比較，簡化2-D模型獲得完整驗證。此外，為了提高功率密度，橫流式馬達需高強度磁石設計，導致橫流式馬達在製程上，因磁石強力磁性造成組裝困難，且容易有鐵粉等雜物吸附，故本研究提出裝配後充磁有效解決上述問題。在裝配後充磁座之設計過程中，以有限元素方式進行磁化特性模擬分析。最後將裝配後充磁方法與前述因製作考量所提出之橫流式馬達，搭配環狀磁石進行模擬分析，其磁化模擬結果獲得驗證。

This dissertation proposes two innovative designs which are composed of fan motors and a transverse flux motor (TFM). A novel fan motor with a 3-D stator structure using a soft magnetic composite (SMC) is established to reduce the hub size and allow more airflow. The proposed prototype is 10% smaller than the conventional models. Experimental results are given for evaluating the performance and feasibility of the presented design.
This study presents a novel topology for claw pole TFM with SMC. The use of ring-magnet can greatly simplify the TFM structure and reduce the manufacturing cost. The proposed simplified 2-D field analysis appears to be of acceptable accuracy as validated by both the 3-D finite element analysis and the comparison between the calculated and experimentally measured Back-emf. Furthermore, to increase the power density, TFM may rely on high intensity magnet design. However, the required magnetized magnets may hence cause manufacturing problems during the process of handling and assembling ferrous debris. This study proposes a sub-assembly magnetization approach, which is a magnetization technique for the TFM rotor equipped with multi-pole magnets. Simulation results confirm that the permanent magnet of the TFM can be successfully magnetized.
