    Abstract: 本論文探討電動式磁浮軸承(Electrodynamic Bearing)的相關設計與分析方法,進而應用於飛輪儲能系統之中。飛輪儲能系統含有被動式磁浮軸承,混合式磁浮軸承,電動式磁浮軸承與內藏感應式馬達。被動式磁浮軸承與混合式磁浮軸承與電動式磁浮軸承中永久磁鐵皆以海爾貝克排列,混合式磁浮軸承採用空心線圈,可以改變電流方向產生吸力或推力,優點為消除負剛性影響。電動式磁浮軸承需要極高轉速以產生足夠的磁浮力,本論文探討之飛輪儲能系統額定轉速下普通的電動式磁浮軸承作用非常微小,故本論文欲探討使用海爾貝克排列之電動式磁浮軸承並進行尺寸最佳化以期在額定轉速下電動式磁浮軸承能對飛輪系統產生幫助。
    This study focus on analysis method and design of Electrodynamic Bearing, for combining electrodynamic bearing with ring type flywheel energy storage system now under study. This flywheel energy storage system equipped with axial passive magnetic bearing, hybrid active magnetic bearing, build-in induction motor and electrodynamic bearing. This study use halbach array on axial passive magnetic bearing, hybrid active magnetic bearing and electrodynamic bearing. Air coil is used in hybrid active magnetic bearing. We can change the direction of current in the coil to create either attraction force or repulsive force. The benefit of this design is cancelation of negative stiffness.General speaking, electrodynamic bearing need extreme high rotation speed to generate sufficient levitation force. The rated rotation speed of flywheel energy storage system now under study is too low for electrodynamic bearing to operate. This study try to replace normal permanent magnet arrangement into size optimized halbach array. Expect the halbach array electrodynamic bearing can provide sufficient levitation force under rated rotation speed of flywheel energy storage system.
