brush material

Test procedures for determining physical properties of brush materials for electrical machines
确定电机电刷材料物理性能的试验规程
The traditional ag / graphite electrical brush is a kind of excellent electrical contact material . with the increase of the content of graphite , though the properties of lubrication may be increased , the properties of mechanical and electrical are linear decrease . the applications will be very difficulty in complicated environment
传统银-石墨电刷材料是一种很好的电接触材料，但随着石墨含量的增加，虽然润滑性能增加但其相对密度、硬度、导电性能都直线下降，已很难满足现在各种复杂情况下的应用，因此需要采用一种新的方法或材料来代替石墨，即起到润滑的作用又可增强、导电导热。
