A pair of carbon brushes. A brush or carbon brush is an electrical contact, often made from specially prepared carbon, which conducts current between stationary and rotating parts (the latter most commonly being a rotating shaft) of an electrical machine. [1] Typical applications include electric motors, alternators and electric generators. The ...
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. [2] For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature . [ 3 ]
Alternator (silver) mounted on a V8 engine Alternator voltage regulator (brushes are worn out) An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. Until the 1960s, automobiles used DC dynamo generators with commutators.
Also, the high resistance brush was not constructed like a brush but in the form of a carbon block with a curved face to match the shape of the commutator. The high resistance or carbon brush is made large enough that it is significantly wider than the insulating segment that it spans (and on large machines may often span two insulating segments).
Additional ring/brush assemblies are stacked along the rotating axis if more than one electrical circuit is needed. Either the brushes or the rings are stationary and the other component rotates. [ 1 ] [ 2 ] This simple design has been used for decades as a rudimentary method of passing current into a rotating device.
A DC armature of a miniature motor (or generator) An example of a triple-T armature A partially-constructed DC armature, showing the (incomplete) windings In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. [1]

An early example of electromagnetic rotation was the first rotary machine built by Ányos Jedlik with electromagnets and a commutator, in 1826-27. [2] Other pioneers in the field of electricity include Hippolyte Pixii who built an alternating current generator in 1832, and William Ritchie's construction of an electromagnetic generator with four rotor coils, a commutator and brushes, also in 1832.
