Carbon brush is a device to transfer energy or signal between the fixed part and the rotating part of the motor or generator or other rotating machinery, it is generally pure carbon and coagulant made ??appearance in general is a box, stuck in the metal stent, whichspring pressed it on the shaft, such as oil drilling is completed, the need for testing, it is necessary to put the instrument down from the wellbore, through the carbon brush the signal from a rotating part (the outsourcing wire cable drum) to the ground instrument. Carbon brush looks a bit like rubbing a pencil eraser Article, on top of the wire leads. Volume sizes. Carbon brush as a sliding contact has been widely used in many electrical devices. Material power graphite Baptist grease graphite, metals (copper, silver) graphite.

Its main ingredient is carbon, called carbon brushes, it is easy to wear. Regular maintenance or replacement, and clean up carbon deposits. 

Carbon brush resins, electrical class, and non-ferrous metals class, different materials and processes used in the different motor

Safeguard the normal operation of the motor, the correct choice of the carbon brush model is very important to its technical performance differences due to different raw materials and process selected in the manufacture of carbon brushes. Therefore, in the choice of carbon brush, you should consider the performance of carbon brushes and the motor carbon brushes
