Abstract
A high-precision multi-pole magnetoelectric encoder includes a mounting seat, a rotating shaft, a single-pole magnet ring, a single-pole signal processing board, a shielding shell, an n-pole magnet ring, an n-pole signal processing board, a housing, a conductive rubber pad, an aviation plug, bearings, copper columns, Hall components, and assembly screws. The magnetoelectric encoder improves the environmental adaptability and replaceability of the high-precision multi-pole magnetoelectric encoder by redesigning the structure of the multi-pole encoder. It eliminates errors caused by changes in the position of magnets and Hall sensors during the replacement process, reduces interference caused by the multi-pole magnet encircling the single-pole magnet, enhances resistance to electromagnetic interference, thereby increasing the detection accuracy of the magnetoelectric encoder, and improves the performance and competitiveness of the product.
