silver carbon brush F19 S13 used in generator shaft grounding  : 

What is it ?
Carbon brushes are devices that transfer energy or signals between the fixed part and the rotating part of a motor or generator or other rotating machinery.
It is generally made of pure carbon plus coagulant, and the appearance is generally a square, which is stuck on a metal bracket, and there is a spring inside to tightly press it on the shaft.
When the motor rotates, the electric energy is sent to the coil through the inverter. Because its main component is carbon, it is called carbon brush.
It is easy to wear. Should be regularly maintained and replaced, and clean up carbon deposits.

The carbon brush looks a bit like a pencil eraser, with wires leading out on top. Large and small in size. As a sliding contact, carbon brushes are widely used in many electrical equipment.
