摘要： The invention relates to a method for production of a multi-layer carbon brush (10), comprising at least two electrically-conducting functional layers (12, 14, 16) made from carbon material and at least one insulation layer made from an electrically-insulating material, running between consecutive functional layers. According to the invention, the corresponding multi-layer carbon brushes and the layers with desired thickness can be produced, whereby the carbon material and the electrically-insulating material are applied in a mould in a sequence corresponding to the layer sequence of the multi-layer carbon brush for production (10), in powder form, then pressed and finally heat-treated.
