Abstract: 本論文主要是針對halbach磁排列,與單極向磁排列作比較。在halbach磁排列方式下可以產生較大的磁浮力,比單極向磁排列的方式更為穩定。可用較少的磁鐵運用新的排列方式,取代舊式的滾珠軸承或單極向磁排列。
模擬時halbach磁排列的磁力線的密集度也比較好,單極向磁排列會有分散的情形,整體的穩定性也是halbach磁排列較佳。力的輸出會因磁鐵橫向間距大小而產生變化,磁鐵橫向間距變化影響單極向磁排列最為嚴重。
This thesis is dealing with the comparison between the flat Halbach array and the magnetic array with magnetization in the one direction (unipolar array) in their repulsive force. In flat Halbach array mode, magnetic flux can be superposed on one side and cancelled on the other side, which renders a better device than its contra one, e.g., stronger repulsive force, more stable array fixture and fewer magnets usage. With these many advantages, the new Halbach arrangement may supersede the traditional ball bearings or the single-sided maglev arrangement in the foreseeable future.
The simulation by computer software shows that Halbach array offers tighter, higher magnetic flux intensity and better overall stability than its counter case of unipolar array. Both cases reveal their repulsive force are strongly influenced by the size of magnets and their lateral spacing between them, and is more severe for the latter.
