The carbon brush conducts electricity between stationary and rotating parts through sliding contact. The performance of the carbon brush significantly affects the performance of rotating machinery, making its selection a crucial factor. At Huayu Carbon, we have extensive experience in developing motor brushes for garden tools. Considering the high-speed characteristics of garden tool motors, we have developed the H series graphite carbon blocks, which perfectly match the specific motors of garden tools. This ensures they adapt to high motor speeds while providing longer motor life.
We utilize advanced technology and quality assurance expertise honed over years of research to develop and produce carbon brushes tailored to various customer needs and applications. Our products have minimal environmental impact and are suitable for many different applications.
The Huayu Carbon vacuum cleaner carbon brushes are characterized by low contact pressure, low electrical resistivity, minimal friction, and the capability to handle a wide range of current densities. These brushes are engineered to compress within the GT plane to precise dimensions, making them an ideal material for cost-effective appliances operating at voltages up to 120V.
