The carbon brush transfers current between the stationary and rotating parts by sliding contact. Because the performance of the carbon brush has a significant impact on the performance of the rotating machine, the choice of carbon brush is a crucial factor. At Huayu Carbon, we develop and produce carbon brushes for a variety of customer needs and applications, applying superior technology and quality assurance know-how to us develop our field of research for many years. Our products have minimal impact on the environment and can be used in many different applications.
The Huayu Carbon vacuum cleaner carbon brush exhibits reduced contact pressure, low resistivity, minimal friction, and the ability to withstand a wide range of current densities. These brushes are designed to be compressed to specific dimensions in a GT plane, making them ideal materials for cost-effective appliances operating up to 120V.
