China Power Tools copper carbon graphite brush for Electric Angle Grinder motor
NIDE can produce different types of carbon brushes and graphite
products. Our carbon brushes are widely used in automobile
starters, car alternator , power tool motor, machinery, molds,
metallurgy, petroleum, chemical, textile, electromechanical,
universal motor, DC motor, diamond tools and other industries. The
company is backed by first-class production technology and advanced
equipment, with various professional and technical personnel,
senior engineers and experienced production workers. We can provide
customers with various types of carbon brush customization and
processing to meet customer needs.
We fully implement the ISO9001 quality certification, and at the
same time introduce advanced foreign production technology and
formula, the products produced are widely used in many fields, and
are sold well in domestic and foreign markets, and are exported to
North America, Southeast Asia, Europe and other regions.
We manufacture and design many patterns, grades and types of carbon
brushes ensuring the correct carbon brush is available to meet your
requirements for your motors or generators, and advice on carbon
brush grade selection is given by our technical experts. The
benefits to our customers include carbon brushes that can increase
uptime and reduce maintenance costs by improving machine
reliability and availability.
We have a strict control system of our product. Our traceability
system focus on the inspection not only in the production process
but also with raw material(like graphite powder, copper powder)
incoming test.
Technical requirement
Material | Model | Resistance | Bulk density | Rated current density | Rockwell hardness | loading |
Carbon black | D308 | 40±40% | 1.62±10% | 10 | 86(-45%~+25%) | 100KG |
D374L | 50±50% | 1.71±10% | 12 | 82(-50%~+67%) | 100KG | |

Advantage: high strength, low bulk density, good rectification performance | ||||||
Application of D308: suitable for mirco DC motor, like voltage regulator | ||||||
Application of D374L: suitable for small high speed series excited motor | ||||||
Application of D374B: suitable for traction motor, generator motor, exciting dynamo motor or DC motor which commutator cannot be used |
Carbon brush features:
Our electrical carbon brushes are made from low friction conductive
carbon materials, Selecting the correct grade carbon brush is
important for commutator performance, maximum brush life, and high
motor performance.
Our carbon brushes are consistent reliable electrical performance
and low wear rates on motors and generators.
Good quality
Small spark
Low noise
Long duration
Good lubrication performance
Good electric conductivity
Carbon brush Application:
Our carbon brush is suitable for Car motorcycle carbon brush,Power
tool carbon brushm, Noil carbon brush, DC motor carbon brush, AC
motor carbon brush ,generator carbon brush, etc. They are used in
steel processing, mining, power generation, traction and a wide
range of general industrial applications all over the world.
Carbon brush importance:
1. The external current (excitation current) is added to the
rolling rotor through the carbon brush (input current)
2. Bring the static charge on the large shaft through the carbon
brush to the earth (earth carbon brush) (output current)
3. Lead the main shaft (ground) to the protective device for the
rotor grounding protection and the positive and negative voltage of
the rotor
4. Change the current direction (in commutator motor, the brush
also has a commutation function)
Information needed for carbon brush inquiry:
It will be better if customer could send us detailed drawing
including below information.
1. Carbon brush dimension: length, width, height, lead wire length
2. Carbon brush material:
3. Carbon brush voltage and current requirement.
4. Carbon brush applications
5. Required quantity
6. Other technical requirement.
We have a wide range of carbon brush. Our carbon brush has a wide application, such as automotive industry, household appliances, hammers, planers and etc. We directly supply our carbon brushes to many countries, like USA, France, Turkey etc. We could customize carbon brush for our customer.
