Dudley’s notes DC Electrical
and Electrical Systems/Fundamentals of Service, John Deere
have taken a look into generators and how they work. We have also taken a look
at alternators and their features. I have given you information on both of
these electrical devices, now it’s up to you to decide which one you think is
more suitable for your needs.
You need high RPM’s to work, you also need pulleys or gears to run.
inexpensive and easy to find
The 12-volts the alternator produces is
used to charge the battery and also to power all of a car’s electrical systems
like the computer, headlights, and radio
Inside an alternator is a rotor that
spins at high speed because of the belt
that’s connected to the engine’s crankshaft. The rotor spins past stator
windings inside the alternator which creates an electromagnetic field, which is
then converted by diodes into direct current. Alternators have vents in their
aluminum housing that help keep it cool during use.
we need to ask, what’s inside an alternator?
alternator is a type of generator that generates electric power in your vehicle
and is a major part of your vehicle’s charging system. Whenever your vehicle is
running the alternator is charging your battery and supplying electric power
for your vehicle’s electrical systems. An alternator is attached to the engine
and is driven by a belt.

Now that we have talked about generators
let’s talk about alternators which are very similar to generators.
Most are not good at low rpm, large sizes are hard to find, small generators
have limited power output, hard to maintain.
shaft transfers mechanical energy to the generator and turns the coil through
the magnetic field.
brushes are always in contact with the commutator and are attached to the wires
coming from the generator. The commutator rotates while the brushes are
stationary, transferring current from the commutator.
commutator is attached to a coil. In a generator the commutator ring is
composed of sections of bars. The commutator transfers the current from the wire
coil to the brushes.
armature rotates through the magnetic field cutting the lines of the magnetic
field. This produces an electric current inside the armature coil.
When the generator produces electricity
it creates a magnetic field which is very important to the operation of the generator.

is a generator? The
purpose of a generator is to convert mechanical energy into electrical energy.
A direct current generator produces current that flows in only one direction.
The purpose of this report is to inform people who are interested in
Alternators and Generators. First we will be looking at how a generator works,
then how an alternator works.
