摘　　要：基于磁编码器多极磁鼓表露场分布的均匀磁化理论模型，采用数值分析方法计算磁编码器多极磁鼓的表露场分布，得到了多极磁鼓的表露场分布的数值表达式．Based on the uniform magnetization model of the surface magnetic field distribution on multi pole drum for magnetic encoder, the surface magnetic field distribution on multi pole drum for magnetic encoder was studied with numerical analysis method, and the general expression of surface magnetic field distribution on multi pole drum was found. The results obtained are useful for optical design of magnetic drum.
