electric generator

08/09/2007 2:34 AM

Im sure this was asked in the past but is there any way to build a electric generator even if there is a battery in the system.

If you can give me some advice that would be great.

Just use an old generator (where replaced by modern alternator ) from a 60's car or truck .You will get all the 12 or 24 volt you can use .

I'm not sure I understand, have another go at the question.

There's a vast number of systems where a generator charges batteries, not even counting vehicles.

Most generators are AC..it's just simpler/more convenient that way...this is nornally rectifed (with a big bridge rectifier) to turn it into DC...

The DC will almost certainly need regulating in some way to match it up to the battery.

This is all theoretically simple...but needs to be right if you don't want to ruin batteries!

(That's the thing with electronics...it's simple in theory, but the reality is vatly different)

Hope this answers the Q

Del....

"any way to build a electric generator even if there is a battery in the system?"

Oddly phrased question. Assuming your not a large power company that can distribute a.c. power directly from a generator at a certain frequency, you would probably charge a battery and then use an inverter for a.c. at a controlled frequency.

It seems that you intend a dual system.

Years ago on the farm we created and used a dual system.

Some of the lights were wired for both a wind turbine Edison battery system and a diesel operated AC generator.

The DC had a solenoids to isolate it when the generator was running.

The switches were placed on the common wire with each bulb on the appropriate power source, We used the term Y system.

It worked quite handy. The lights switched over automatically whenever the Gen was started or stopped.

The diesel was started with a remote switch situated in the house

Modern Health and Safety rules must be consulted.

Question is too unclear for any sort of useful answer.

Hello

Please restate your question.....Do you want AC and DC? How much voltage and or amperage are you in need of ???

well i was thinking ac would do also so what does every one think but then if i went ac what would the battery voltage be

and yes its ac not dc but i could change my i there is souch a battery for ac i thought there was only dc batterys but i could be wrong

No...

No such thing as AC battery.

read my first reply.

Batteries on their own are always DC.

sorry it has taking me a while

what i am building is a generator that does not run on fuel what so ever

the components that i am thinking of using are a electric motor a dc battery and a altenator if anyone can tell me what do i need else like a control module or anything in that area that would be great

"what i am building is a generator that does not run on fuel what so ever"

This is commonly referred to as a perpetual motion machine, which is impossible.

I believe you plan to use a motor to run a generator to charge a battery. That motor requires energy to run, which means fuel being burned at the power plant, or solar energy, where the fuel is being consumed at the sun.

The motor gets hot (energy lost), and the generator gets hot (more energy lost). There are much more efficient ways of charging the battery.

If, as I suspect, you are trying to get 'free' electricity, that energy has to come from somewhere, usually the sun. Try using a windmill to turn your generator, or solar panels to convert sunlight directly into electricity.

Do you actually read your posts before you submit them? I think not!

Try using complete sentences, punctuation, and capital letters when appropriate. Then we might be able to understand what it is you want to know!

It may sound rude to you, the truth hurts sometimes, but I do not feel that you have the smallest inkling as to what you need to do, therefore I urge you MOST strongly, to lay out, in a good text posting, EXACTLY what your aims are.

If you do not do this, I think we will all have really problems trying to help you.....(we are having problems already .......!)

I am guessing here, but assuming you are in the USA, then you probably need 110 volts at 60 Hz, or if somewhere else, 230 volts at 50 Hz, am I correct, if so, which one is correct? Or is a DC system better for you?

I am sorry to go over old ground again, maybe asking questions that have been previously answered, but your last posting seems to have blown away to a degree, what you have up to now stated stated.....(little though that was.....!)

.......and what we need right now are some hard basic facts, from you.......or just forget the whole thing please.....

Thanks in advance for your full understanding and help in this matter.

Wolfer562002: I am would be happy to help you if you can explain to me (us), the total project, I need a full functionality specification of the total program even if it is just a home project..........If.... and I am assuming this, the project is for Wind Power generation, there are serious consequences for improper implementation. Currently we manufacture: Inverters, converters, isolators and similar items....even controls for electrical drive systems for commercial submarines as well as power generation from Drogues which are trailed through the sea....To provide any assistance you at all, you need to be far more communitive..............and disciptive. Otherwise I cannot continue with this thead.
