Brush Holder

Brush holder transfer the current from the stationary equipment (stator) of electrical machines -motor or generator- to the rotating part (rotor) and perform the commutation without arcing during this process; They are products with slippery feature so that they do not damage the surface on which they work.

What Does a Brush Holder Do?

• Brush holder are mounted inside the brush holder housing and provide contact with the ring and the collector.
• Companies have a wide range of products in brush holder production: Motors, Generators and Alternators, Grounding products, Current and signal transfers are the products in this product range.
• In addition, these companies have a very wide portfolio of electro graphite products needed for DC motors. These include many world-renowned grades such as EG34D, EG367, EG8220, AC137.
• Electrographite grades; It is obtained by converting natural carbon into artificial carbon as a result of baking and electrolysis of carbon powders and petroleum coke at temperatures higher than 2500 °C.
• LFC brand for Turbo Generators is a product class accepted by the whole world and the most well known is LFC554. CG626 is our most preferred coal brush quality in wind turbines all over the world.
• Its hardness and friction coefficient are low in order to absorb shocks and mechanical vibrations in the best way; They are products produced from natural or artificial graphite with the help of various chemical binders.
• Quality brush holder manufacturers offer amorphous carbon and bakelite graphite grade brush holders for small powerful motors.
• Amorphous carbon grades, also known as carbographic; It is produced by adding suitable binders to carbon and petroleum coke and cooking at high temperatures in order to be more resistant to high temperatures and variable loads.
• Bakelite grades; They are products that have been impregnated with natural or artificial graphite, resistant to high temperatures, in order to increase electrical and mechanical resistance.
• Also, brush holder companies offer metallic quality brush holders made from metal alloys for grounding systems.
• These materials are; purified natural graphite; After mixing with metal powders such as copper, silver, etc., it is produced by pressing and baking, providing appropriate hardness and breaking strength.
• Especially cement factories, paper mills, mines etc. produces metal graphite brush holders developed for ring induction motors used in industries
• These materials are; purified natural graphite; After mixing with metal powders such as copper, silver, etc., it is produced by pressing and baking, providing appropriate hardness and breaking strength. You can contact us to get information about the brush holder.
