Title:
HIGH-PRECISION MULTI-ANTIPODE MAGNETOELECTRIC ENCODER
Document Type and Number:
WIPO Patent Application WO/2023/221953
Kind Code:
A1
Abstract:
The present invention relates to a high-precision multi-antipode magnetoelectric encoder, belongs to the field of high-end equipment manufacturing, and relates to the field of high-precision servo position detection, in particular to machine tool servo position sensor manufacturing. The technical scheme is as follows: the high-precision multi-antipode magnetoelectric encoder comprises a rotating shaft, a mounting base, a shielding shell, a shell, a copper column, a single-antipode signal processing board, a single-antipode magnetic steel ring, an n-antipode signal processing board, an n-antipode magnetic steel ring, a bearing, an aviation plug, a conductive rubber pad, and an assembling screw. The multi-antipode magnetoelectric encoder structure is redesigned, the environmental adaptability and replacement installation of the multi-antipode magnetoelectric encoder are improved, errors caused by magnetic steel and Hall position changes in the replacement process are eliminated, interference caused by a magnetic steel ring sleeve is reduced, and the anti-electromagnetic interference capability is improved, such that the detection precision of the magnetoelectric encoder is improved, and the performance and competitiveness of the product are improved.
