WebAn electrical brush is mainly a carbon-type brush. In a DC motor it is used to carry out commutation together with a commutator for many years (Shobert 1965; Holm 1967; Slade 1999 ). Further, it is used to supply exciting current to a generator with a slip ring. A carbon-type brush is mainly divided into carbon brush and metal-graphite brush. WebThe lowly brush is underrated and misunderstood. The brush grade, brush pressure and spring tension, as well as the effect of load and humidity are each important to brush performance in DC machines, wound rotor motors, and synchronous machines. This presentation covers: Importance of brush grade; Effect of humidity and load (current)
