Based on the theory of static magnetic field, the surface magnetic field on the high-resolution multi-pole magnetic drum for a magnetic rotary encoder was analyzed. The visual curves of the surface magnetic field distribution were obtained by numerical calculation and plotting.
We analyse the structure of magnetic rotary encoder(MRE),its work principle,the recording media on the magnetic drum and the magnetic sensor,and introduce the application of MRE,the development prospect and Point out that MRE is very important for the development of high technology industry in the future.

The Co-P film was applied to the magnetic drum,whose diameter was 40mm,and then was recorded 512 magnetic poles. The output signals were perfect,and the output waveforms were steady. The pulses account was integral.
This paper present s a system of magnetic encoder-based measurement and control of the position f or vehicle,which is used for transportation of hot-rolling wide strip unloaded from strip roller.Its principle is described,which in-cludes that of magneti c rotary encoder?design of amplifier?the circuit of shaping and doubling frequ ency?interface of single-chip microcomputer and program of measurement and co ntrol.Features of the system are run under bad environ-ment ?high reliability and accuracy?simple str...

Based on the theory of static magnetic field, the surface magnetic field on the high-resolution multi-pole magnetic drum for a magnetic rotary encoder was analyzed. The visual curves of the surface magnetic field distribution were obtained by numerical calculation and plotting. A good AMR magnetic head for the magnetic rotary encoder was designed. The results of theoretical analysis and practical test were contrasted. The results are accorded in the output signal's shape and amplitude of the AMR magnetic he...
