本論文基於電磁致動器的體積、施加電壓和吸力這三個主要設計特徵，提出針對內置線圈電磁致動器的設計和分析方法。在不改變框架外形尺寸的情況下，本論文的目標是通過改變磁極表面積、鐵框架的厚度和電磁材料去獲得更大的吸力或高斯值。為了提升設計之成功率及降低研發之成本，我們將使用ANSYS Maxwell有限元素分析軟體去分析及驗證設計可行性。ANSYS Maxwell是業界廣泛使用的商業有限元素分析軟體，在設計圖中可應用電磁低頻有限元素分析方法來找到最佳設計參數，以利最大化可達成的高吸力或高斯值能力。最後我們將透過實驗結果驗證本論文所提的電磁有限元素分析模擬結果。未來可將電磁有限元素分析技術擴展至工業的電磁致動相關產品之研發上，例如：線性可控制致動器、電磁吸盤、電磁閥等裝置。

This paper will propose the designs and methods of analysis for a built-in coil electromagnetic holding device based on three main design characteristics: volume, applied voltage, and suction force. Our aim is to achieve the greater suction force or Gaussian value without changing the external dimensions of the frame, by varying the magnetic pole surface area, the thickness of the iron frame, and/or the electromagnetic material. In order to improve the success rate of the design and reduce the cost of research and development, we will use finite element analysis software of ANSYS Maxwell to analyze and verify the feasibility of the design. ANSYS Maxwell is a commercial finite element analysis software widely used in the industry. Based on the design drawing, the electromagnetic low-frequency finite element analysis method can be used to find the optimal design parameters to maximize the capabilities for achieving a high suction or Gauss value in the proposed design. Finally, we will verify the simulation results of electromagnetic finite element analysis proposed in this paper through experimental results. In the future, the electromagnetic finite element analysis technology can be extended to the research and development of industrial electromagnetic actuation related products, such as linearly controllable actuators, electromagnetic chucks, solenoid valves and other devices.
