基于無軸承薄片電機的需要而開發(fā)和研究了兩種低成本霍爾位移傳感器，介紹了基本的工作原理，對模型進行了理論分析，設計了匹配電路與霍爾元件相結合，并在動態(tài)和靜態(tài)下進行了實驗。實驗結果表明該位移傳感器有較高的測量精度，與理論分析比較吻合。應用結果表明該位移傳感器性能優(yōu)良，能夠滿足無軸承薄片電機的要求。
Abstract: Two kinds of low cost Hall displacement sensor are exploited and researched for the bearingless slice motor. Basic operating principle is introduced and analyzed. Matching circuit is designed to combine with Hall element and experiments are performed under the dynamic and static situation. The experiment proved that the displacement sensor has upper sensing precision and it is comparatively inosculate with theory analysis. The applied result proved that the displacement sensor has good performance and it is suitable for the bearingless slice motor.
