Although the resistance was of the order of tens of milliohms, they were high resistance enough to provide a gradual shift of current from one commutator segment to the next. The term brush remains in use. creighton farms homes for saleWebAn 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. buck\\u0027s-horn hi
