ABSTRACT:
In a current transfer brush which includes a frame element holding together a flexible slider member containing several graphite fibers which are at least partly coated with an electrically conducting material, the slider member is made of a stack of a plurality of mats of highly graphitized graphite fibers, the mats extending at least approximately perpendicular to the contact surface of the brush with at least some of the fibers in mats coated with an electrically conducting material in order to give improved electrical characteristics for the brush over brushes utilizing a graphite block as the slider member, with the brush particularly useful in commutator machines.
