Abstract:
Generators are devices which employ the principal of
electromagnetic induction to convert mechanical energy
into electrical energy. A generator utilizes mechanical
power from an operating engine to restore the electrical
charge in the vehicle's battery. The battery, in turn,
powers the starter motor for cranking the engine and
other vehicle electrical systems. There are two basic
types of generators; one type produces a direct current
(DC) and the other type produces an alternating current
(AC) and is more commonly called an alternator.
Ai terna tors are lighter and more compact than DC
generators, and are better at charging a battery at
lower speeds. Most modern cars have been built with
alternators but generators are still found on older cars
and trucks.
