Graphite Carbon Brush 5*12.5*35-Washing Machine Motor Spare Part

Carbon brushes are sliding contacts that are widely used in a variety of electrical equipment. At present, we have provided high-quality carbon brush accessories for industry, aerospace, electrical machinery, metallurgy, chemical industry, building materials and other industries. Such as carbon brushes, brush holders, collector rings, carbon brush holders, etc. Our carbon brush products are mainly made of electrochemical graphite, grease-impregnated graphite, and metal (including copper, silver) graphite. Different types of carbon brush parts can be customized according to customer needs.

Carbon brush application

Household appliances, power tools, automobiles, wind power, steel mills, ports, cement, textiles, motorcycles, printing, forklifts, etc.

Manufacturing Materials and Processes

(1) Natural graphite

Natural graphite is the main raw material of this type of carbon brush. The binder is made of pitch or resin, which is baked or sintered at 1000 degrees. This type of motor has good lubricating performance and current collecting performance. Most of them are used for small and medium-sized DC motors and high-speed turbine generator collector rings that run smoothly.

(2) Electrochemical graphite

The main components are carbon black, coke and graphite and other carbon powder materials, which are converted into microcrystalline artificial graphite after being treated at a high temperature of 2500 degrees. This type of carbon brush has excellent commutation and self-lubricating properties, and is widely used in various AC and DC motors not only for long life, but also for less wear on the commutator.

(3) Metal graphite

The main materials of this type of carbon brush are electrolytic copper and graphite. According to the needs of use, other metals such as silver powder (used on precision instruments, which are very expensive), aluminum powder, lead powder, etc. are sometimes used. These carbon brushes are divided into binders and no binders. This type of carbon brush has both the friction characteristics of graphite and the high conductivity of metal, so it is suitable for low-voltage motors with high load and low commutation requirements (such as car starter motors, etc.). Its peripheral speed does not exceed 30 m/s.
