摘要

本研究自行研發新式非接觸的角度測量，應用霍爾感測器與永久磁鐵的結構，所設計之轉角量測系統，是具有新穎控制技術、測量精度高、高可靠運行等優點。在無接觸亦即無磨擦損耗情況下，此種組合有較長的操作壽命，特別適用於需要長時間使用的振動環境下。利用霍爾元件對磁場變化產生的霍爾電壓，經查表或公式推得角度，可適於特殊環境條件下運作，比如高振動、高濕度或灰塵中。此外依據量測檢驗品保標準在QS 9000、ISO/TS 16949等國際法要求下，針對所建立的角度量測系統設計之相關的實測結果，達到符合國際法規檢驗量測設備的水準，可廣泛地應用在非接觸角度測量領域。

An application permanent magnet and Hall Effect sensors is introduced in this paper. This combination provides a longer life-span due to its wear-free. The main component of angular position estimation system is Hall sensor. This angular sensing are combined with a magnet and two linear Hall elements, which provide a sine-cosine pan for the microprocessor to determine the angle of the rotary part within a single turn. Such a contactless angular sensing derive is particularly reliable, compared to the traditional conductive-plastic-film potentiometers, under environments with sustained vibrations. Reference material is the QS 9000 and ISO/TS 16949 quality standards on the requirement of measurement system. The system arrival to fit of practical application is given. It can be widely used in the angular measurement field.
