Resin-bonded carbon brush
Resin-bonded carbon brush is one of most important products of BOYO CARBON. The material of this kind of carbon brush which is based on graphite, and have a resin bond. This type of bond produces a high electrical resistance which endows the grades with extremely good commutating ability. Their current carrying capacity is ,however, limited. The most important application is to used in the washing machine motor and cleaner motor,etc.
The following is the carbon grade made by BOYO CARBON.
