Application of molybdenum disulfide in carbon brush

The brush is a conductive part that makes sliding contact with the moving part to form an electrical connection. We could find brushes from almost all DC motors and commutation motors, Carbon brush is one important components of the motor.

 

Molybdenum disulfide is a solid lubricant with a very low coefficient of friction. When the brush contains a certain amount of molybdenum disulfide, it can form a sulfide film with good lubrication. This film is closely adsorbed on the surface of the slip ring, so that the brush still has good lubricating properties under high altitude conditions. In addition, molybdenum disulfide has good water resistance and pressure resistance, has a very low friction coefficient and a high yield strength. Shenyu molybdenum provides high-quality molybdenum disulfide products for most electric carbon customers in the market.
