摘要
本文通过对磁编码器磁鼓空间磁场分布的理论计算和定性分析,找出场点位置、磁极数、磁层厚度和磁鼓形状等因素对磁场空间分布的影响,阐明在一定条件下,磁阻探头存在一最佳空间放置点。
In this paper,We get the magnetic field distribution of multipole magnetic drum in magnetic encoder through calculating and discussing the classic magnetic equations by MATLAB programs, We find some disciplines that the field distribution alters with the alteration of the space site,pole number,thickness of the magnetic drum and the drum size.We draw a conclusion that the magnetic resistive element exists a best space position and we can get it through calculation and analysis.
