摘要

本文以氣封絕緣開關電磁驅動器為主要研究對象，對其作用磁力提出改善。首先，利用電磁驅動器在電領域、磁領域及機械領域等物理現象建立數學模型，並使用ANSYS來計算電磁驅動器的磁場強度、磁通密度等分佈變化；經由ANSYS模擬後的結果和利用Matlab得到的數值以及實測加以驗證，可找到影響垂直推力大小的因素，可作為日後設計者在設計相關電磁驅動器之參考，以縮短設計時程。研究結果顯示，本實驗中藉由設定不同的工作間隙的條件，分析其電磁場的特性，經由改變電磁驅動器的尺寸、磁性材料性質或可動軸心的配置，可獲得更好地特性。

The purpose of this paper is to study electromagnetic actuator and to improve magnetic force. First, we use the physical phenomena of electromagnetic in electric energy field, the magnetic energy field, and the mechanical energy field to establish the mathematical model and using the ANSYS to calculate magnetic field strength, magnetic flux density distribution. By the simulation result of ANSYS and Matlab, we can get result and measured to be verified, the factors that related to influence vertical thrust can be identified. This result can provide future researchers or designers a referral of designing electromagnetic which can shorten the design process. The results of my experiment have showed that the characteristics of electromagnetic fields can be analyzed by setting different the working gap, such as the distribution of magnetic line and magnetic force. Furthermore, there will be a better quality by adjusting the size of electromagnetic drive, the character of magnetic material or the configuration of movable magnetic axis.
