Without a commutator, a agent becomes an alternator, which is a ancillary apart fed generator. When acclimated to augment an electric ability grid, an alternator charge consistently accomplish at a connected acceleration that is absolutely synchronized to the electrical abundance of the ability grid. A DC architect can accomplish at any acceleration aural automated limits, but consistently outputs absolute current.
Typical alternators use a alternating acreage ambagious aflame with absolute current, and a anchored (stator) ambagious that produces alternating current. Since the rotor acreage alone requires a tiny atom of the ability generated by the machine, the brushes for the acreage acquaintance can be almost small. In the case of a brushless exciter, no brushes are acclimated at all and the rotor shaft carries rectifiers to accelerate the capital acreage winding.
