    Abstract: 本論文主要在探討利用霍爾感測器量測磁浮轉子軸、徑向位移。
    量測系統主要包含六顆安裝於定子之霍爾感測器,及安裝於轉子
    上的永久磁鐵作為磁場源。系統原理主要利用進入感測器內的磁
    通角度改變。且由充磁不均及溫度所造成的量測誤差也被降至最
    低。量測系統性能於實驗中獲得令人滿意的結果。由於系統使用
    單軸霍爾感測器,在三維空間磁浮轉子量測方面,論文提供了一
    個低成本且小尺寸的方法。
    This paper presented a scheme to measure axial and radial
    displacement of a magnetically levitated rotor based on linear
    Hall-effect sensors. The measurement system consists of six
    single-axis Hall sensors attached on the stator, and a ring permanent
    magnet mounted on the rotor as the magnetic flux source. The
    system is configured such that the angles of the magnetic flux into
    the sensors are monitored. Consequently, the errors caused by
    non-uniform magnetization and temperature dependence are
    minimized. The experimental results demonstrated a satisfactory
    performance of the measurement system. Since single-axis Hall
    sensors are used, this scheme provides a low-cost and compact in
    size solution for three- dimensional displacement measurement for
    levitated rotors.
