Ive never heard of carbon brushes referred to as coal. Is it a language thing? They are made out graphite, which is also mined, but its different enough from say https://en.wikipedia.org/wiki/Anthracite. I think graphite is actually closer to diamond than it is to coal, in terms of chemical makeup.
Probably. In Swedish many forms of Carbon share the same word “Kol”. It is the word for the element Carbon, but also the fuel Coal. Carbon brushes are called kolborstar “Carbon/Coal brushes”.
Coal. Transfers electricity between the motor housing and the rotor inside the motor.
