Abstract:
      The magnetic rubber materials and multipole magnetic rubber encoder were prepared，and the spatial magnetic field variation law of multipole magnetic rubber encoder was mainly studied. The results showed that，in the axial direction，the maximum magnetic induction intensity of the multipole magnetic rubber encoder decreased rapidly with the increase of the air gap；in the radial direction，the maximum magnetic induction intensity of the multipole magnetic rubber encoder increased first and then decreased from the inside to the outside，and the extreme value was outside the center of the rubber part.
