um i don;t think i explained it correctally i was watching a program, the other day and this guy (the 1 that invented the clockwork radio) just coved in to a house down cornwall and to power his house or at least some of it he built a water wheel which only only turned at about 60 revs a minute he then attached that to a 1-44.2 geer system which was something salvaged from another machine it was at least 10 years old if not older and then atached tat output to the generator and i want to try something simalart just minus the water wheel. at a push i know a few people in the dockyard that with a bit of persuation could build me a gear system but it would be expensive but the generator i know wuill have to be new but i have no idea what suppliers there are.
How big do you want? What voltage and current rating? You can use an automotive heater fan motor, an automotive radiator fan motor, or even a permanent magnet starter motor. A windscreen wiper motor also works, and has a built in gear drive - as does a power window motor if you are looking for low voltage and relatively low power output.
A treadmill motor works for higher output voltage and power.

i;m looking at anythi g that gives about 12 volts at 3 amps but higher is better as i want to start with some small tests around the home but move on to using it for several things at once whick means i will need it to produce more evectricty as i start to use it for more things i can always not use it to it's fll potential at first but if i want to expand then i don;t want to have to get anotther after second hand ones are a good iea but ut us hard to get secondhand parts over her cause all the working ones are usually whiped up by rtepair copmpanys and as soon as they are available.
For 12 volts you want a 24 volt or higher DC permanent magnet motor. I

have a few DC servo motors that would do the trick, but they are in Canada and pretty heavy. Tape drive motors like the Ametec units also work good and were widely available as surplus. Your best bet, currently, is likely a treadmill motor, but if you are in a 2220 volt area the output will be higher than 12 volts!!

You mean the programme "it's hard being green" ? That's not Trevor Bayliss fwiw.
no it is a bbc program called it's not easy being green

Ok - I didn't recall the name exactly.

and it is Richatd 'Dick' Strawbridge and his family. this is the acompanying website

Yes, that's the one I had in mind. He didn't invent the wind-up radio though.

http://www.itsnoteasybeinggreen.org/

I didn't know about that. Thanks for the link.
The programme's been very interesting in many different ways.

Looks to me like a concise request for a clarification.

ok I will aploagise for the fact that I got the wrong person I only found

out about the program cause my counsin mentioned that he was watching it all come together as he lives about 5 mins from the farm.I have found that he didn;t invent that but he was on scrapheap chalange and I shuld have remembered him from there.
I have just purchased the acompaning book that has more detail about what they did on the show. It is available in hardback and paperback, the hardback that I bought was �11.99 i think and that is reduced from it's full proce of �18.99 and that was from amazon.co.uk
My comunication skills are improving sligtly I have only taken english at gcse level (I did progress to college on a microcomputer course) and I must admit that I did do porly in my english exams but at present I am not in any state to go back into education for that though I am working towards it.

Thank you very much for that information I will take it into consideration if you do find any more information or anything else I can use I would love to hear.

Higher voltages give charging at lower RPM speeds. The voltage peak will be clipped off by the battery voltage anyway. Careful if you ever open circuit the monster though. My 48vdc battery was disconnected from the controller and it went up in smoke. I measured 200vac before I got the short circuits back in.

no way? thats nasty have you got any driagrams of your system or photos? i'm mainally doing research for personal use at the moment so anyother systems thatt i can look at are much welcomed.

I have created schematics for my wind turbine controller after a few parts went up in flames. I have modified the circuit so it is less likely to do it again. They had a 7812 regulator to run the level detection circuits and because it's input has a max 30vdc they used an LM317 down regulator to feed that. The inoput to that chip is max 50vdc and it was destined to burn up on a 63v (totally full) battery sooner or later.
The control circuit is pretty simple two 3 phase full wave rectifier bridges. One feeds the battery bank and one feeds a couple of voltage level detectors. One is for low voltage cutout and drops out a relay to disconnect loads upon dead batteries (42v). The other voltage level detector (63v) detects over charging the batteries and picks up a relay putting a heater laod and two muffin fans to disapate some of the enery from a highly active windmill.

The TL783 can tolerate an input voltage of up to 125V. It's even the same pinout as the LM317 IIRC. It does require a minimum load of several mA to work correctly btw.
Graham

I was looking for a regulator that would be capable of a high input-output voltage like the TL783 and could not find one in a few nights search. All the listed high voltage units I could find then were good up to 125v but with only 20-30v dropout from input to output.
I finally gave up and used a zener circuit to drop it to about 20v and then into the 7812. I used four 82 volt, 20K joule MOVs where they had not installed the main capacitor to alleviate some of the posibility of high voltage into the controller for the next time the wind turbine goes open circuited. They gonna go **bang** probably in the next hurricane though...LOL

it's never good when things go bang when there is no combustion involved
