A dynamo normally refers to a DC (Direct Current) generator. An alternator produces AC (Alternating Current) electricity. An alternator in a car actually generates 3 phase alternating current which is converted to direct current using a rectifier.
Generally, vehicle alternators are lighter, cheaper to produce, have better capacity over a wider range of speeds, take less maintenance and generally last longer than an equivalent generator. The one disadvantage is that they must have a battery in the circuit to excite the field coils.

What does a car battery do in a car?
Powers the starter motor and all the other electrics in the car when the engine is not running. When the engine is running, the battery is not needed because the alternator of which works very much like a bicycle dynamo runs all of the electrics in the car. It also keeps the battery charged. If fitted to a bicycle a dynamo will generate electricity to the bike lights when you peddle. An alternator does the same thing but with engine power instead of peddle power. the only difference between a dynamo and an alternator is that an alternator alternates the current from AC to DC a dynamo does not.
Difference between ac dynamo and dc dynamo?
1. AC Dynamo has full rings whereas DC Dynamo has split rings. 2. AC Dynamo produces alternating current whereas DC Dynamo produces direct current. 3. IN AC DYNAMO, CURRENT KEEPS CHANGING EVERY HALF OF A CYCLE WHEREAS IN DC DYNAMO, CURRENT FLOWS IN SAME DIRECTION.
What is a machine that creates electricity?
It may be called a generator, alternator or dynamo.
What are some ways to produce an electrical current?
Dynamo, alternator, solar panel.
What are the difference between dynamo and motor?
A dynamo takes in motion and outputs electricity and a motor takes in electricity and outputs motion. A dynamo converts mechanical energy to electric energy while a motor converts electrical energy to mechanical energy.
Is there a difference between changing the alternator in a 2.3L grand am and a 2.4L?
Yes, there is a difference between changing the alternator in a 2.3L grand am than there would be in a 2.4L grand am, because it needs a more powerful alternator to turn over the engine
What is another word for electric generator?
An alternator and a dynamo could both be called generators.
Is the dynamo of a bicycle light ac or DC?
There are two types of electrical generator. One is a dynamo, which produces d.c. The other is an alternator, which produces a.c.
What is a device used to convert mechnical into electrical energy?
A generator or an alternator. Also known as a dynamo.
What does a stator do on motorcycles?
If we are talking about a dynamo or an alternator, a stator has a rotor inside it. When the rotor turns, electricity is generated.
How does the composition of the inner core and outer core explain the Dynamo theory?
Dynamo theory is the idea that a magnetic field generator exists within the Earth's outer core. It is this generator that explains the difference between the inner and outer core.
5 uses for a magnet?
electric motor, dynamo / alternator, loud speaker, rail gun, metal detector,
