摘　　要：磁编码器由磁鼓与磁阻探头组成。它们之间的间隙大小直接影响着磁编码器的性能和稳定。运用均匀磁化理论，计算了磁鼓空间磁场的大小，对磁鼓与磁头之间的间隙进行了分析。理论分析的结果表明，磁鼓与磁头之间的最佳间隙为：０．５～０．７λ。理论分析与实验研究符合较好。Magnetic encode is compose of magnetic drum and magnet-resistant head. Their gap directly affect the function and output of encoder. Space magnetic field of drum has been calculated by using theory of well-distributed magnetization. Through it, the gap affecting the magnetic encode is analysed, and the best gap calculated is 0.5～0.7λ.The analyse conformed to experiments well.
