Using of copper-graphite brushes
A copper-graphite, or carbon brush, is a technically necessary component of an electric motor. A real user cannot touch or see these brushes, as they are hidden in the motors of the devices, which will be discussed later, but in this article we will try to reveal the principle of operation and the benefits of copper-graphite brushes.
Usually we associate the word "brush" with a toothbrush, a shoe brush, or a brush for cleaning clothes, but not with a small graphite product that makes a motor working. This name was fixed in the middle of the 19th century, when the first electric motors and generators used brushes made of bonded copper wires (copper-braided brushes). Subsequent inventions replaced them with graphite (carbon) blocks, so the concept of "brush" has survived and people continue to use it.
