摘　　要：阐述磁电编码器的结构由磁敏元件和永磁体组成,它是一种角位移传感器。探讨磁编码器的设计,它属于高分辨率、单对磁极编码器。分析表明,这是一种采用新型高性能巨磁阻效应(GMR)的传感器,所需的材料成本和时间成本都比较低、体积小,精确度高、稳定性能好。This paper describes the structure of a magnetoelectric encoder, which is composed of magnetic sensing elements and permanent magnets. It is an angular displacement sensor. Explore the design of a magnetic encoder, which belongs to a high-resolution, single pair magnetic pole encoder. The analysis shows that this is a new type of sensor with high performance Giant magnetoresistance (GMR), which requires low material cost and time cost, small size, high accuracy and good stability.

关 键 词：巨磁阻效应传感器 编码器 磁场分析
