A generator wants periodic brush substitution , for the reason that its DC output all goes throughout the brushes. Within an alternator a Considerably smaller existing is fed with the brushes on the rotating area windings, so that they very last more time. The A/C output with the alternator is altered to DC by rectifier diodes inside the alternator, so an auto alternator really puts out DC electrical power.
