Abstract

This invention relates to anisotropic rubber magnet, a motor that equipped this rubber magnet as well as a magnet roller, and a rubber magnet manufacture method. It comprises at least the rubber material, the plastic agent, slippery agent and the ferrate powder rubber magnet. Regarding the rubber material 100 weights part, the plastic agent ratio is 10-30 wt %, slippery agent ratio is 8-30wt %, the ferrate powder ratio is the definition like below ferrate quantity is above 66%, directional is 84% above anisotropic rubber magnet. The ferrate quantity = [(from density computation ferrate powder volume) /(from various densities computation various ingredients volume)] x100 (however, the ferrate powder density is 5.1 Mg/m3, organic ingredient (rubber material, plastic agent and slippery agent) density is 1.0 Mg/m3)
