摘　　要：基于静磁场理论，建立了磁编码器多极磁鼓的表露场分布均匀磁化模型，得到了磁编码器多极磁鼓的表露场分布表达式，为多极磁鼓的参数优化设计提供了理论依据．Based on the theory of static magnetic field, the uniform magnetization model of the surface magnetic field on multi pole magnetic drum for magnetic encoder has been built. The expression of surface magnetic field on multi pole magnetic drum for magnetic encoder has also been built. The research results are important for optical design of magnetic drum.
