The lifespan of carbon brushes is usually between 1000 and 3000 hours. The following is a detailed introduction to carbon brushes:
The main function of carbon brushes is to rub against metals and conduct electricity, which is different from friction between metals. Friction between metals increases due to sintering of the contact parts, but this is not the case with carbon brushes, because carbon and metal are two different elements that do not cause sintering at the contact parts.
When using carbon brushes, you need to pay attention to the following:
Carbon brushes need to be replaced when they wear out to a certain extent, but it is recommended to replace all carbon brushes at once. If the old and new carbon brushes are mixed, the current distribution may become uneven.
Carbon brushes, also known as electric brushes, are widely used in many electrical equipment as a sliding contact. Carbon brushes are mainly used in the product materials of graphite, grease-impregnated graphite, metal (including copper, silver) graphite.
