What is the difference between Dynamo and car generator?

Question:


Answers:

Second hand Citreon pacasso problem.?

The dynamo (or DC generator) was heavy, had to be running at a fairly high speed to put out over 12 volts to charge the battery sufficiently, and the brushes wore down quickly.

Do you know how to drive a manual transmission? if you don't would you like to learn?


The alternator used on all modern cars produces AC voltage that is rectified by diodes, and will put out 13 plus volts at low RPMs. Alternators are much lighter than generators, cause less drag on the engine and last much longer. Most modern alternators also have internal regulators.

Why do people drive with their fog lights on when its not foggy,cause if they think they look cool they don't

Not much basically the same scientific principle and design.

Any idea why the http://indianrail.gov.in/ site is not working these days?


In fact the dynamo is pretty mcuh identical to an Electrical motor aswell.

Where can i rent a car in the UK if i am 21 years old? does any one know any websites? thanks?

nothing except the word dynamo was used mostly in europe, but don't confuse these with a car alternator which is different.

What is the semi-precious metal used in the manufacture of catalytic converters?

Language English call it a spanner, we call it a wrench/ the aussies call it a boot, we call it the trunk. Dynamo is English I think.

Best way to transport my 16 year old son to a Wilderness school.?

a dynamo only charges at 12 volts and was used in old cars befor the times of all the electricks we have in cars today
an altinater will put out between 13.5 volts and 14 volts and is used on all new cars for the reason above.
a car generater never heard of it must be american word

Does anyone know what 'station waggons' mean, where the name originated etc?

You mean dynamo and alternator , the differance is an alternator charges all the time at a constant rate even on tickover, a dynamo only takes up a charge when engine speeds increase and shuts down on tickover

Name my ride?

A Dynamo generates DC electricity. Most car generators are now Alternators and they generate alternating current electricity. The car electronics then converts it to Direct Current (DC)

we have a 1993 Honda Accord that is not going out of park any ideas?

A generator generates electricity. A car could have either a dynamo or an alternator as its generator.

Anyone know if you can get a drivers license online? I heard you can but not sure if its true. Just for c car?


The dynamo generates DC power and is not effective at low revs, whereas an alternator generates AC power and works even at idle revs, which is why modern cars all have one instead of a dynamo - because of all the electrical demands these days.

How do i back off from a car deal? What charges can i incur?


Hope that helps

Is is true that the chrome wheels will tear up a Nissan Sentra.?

Both make current from the rotational energy of the engine using magnets and coil windings. Dynamos are an older design and are quite bulky and make a DC current. Alternators are more modern, smaller and efficient and make an AC current which uses a diode pack to convert it to DC for the cars use.
