Voltage regulator

[RostaH]

Hello,

I learned a lot from this website regarding wind generators. But I still have questions.I am building a windmill with the 12 V Delco Remy alternator . Now I am trying to turn off the woltage regulator on this alternator. How do I do it? Do I just take it out or keep it in but isolate it from other parts? In the first option, what can I put instead? The part above the voltage regulator still needs to sit on its original space, right?

Thanks

I hate to be a wet blanket but an unmodified auto alternator is NOT a good choice. You'll need between 1000 and 2000 RPM to make it work. If you want to pursue this angle you will need a belt, chain or gear box to get the speed necessary to produce any usable power. Now to directly answer you question. If you can get the alternator up to proper speed the stock regulator should work, provided it connected correctly. Not being a gear head I cant speak to that particular combination of alternator/ regulator. I do know that you will need a way to switch off the regulator when the alternator is below operating speed. Some have used a vane to operate a switch. I had though that a timer might be able to activate the field periodically and when it put out voltage it would keep the field coil active.

Use the search function here to look over articles in the archive for ideas and more info.

Hello,

thanks for the answer. I am aware of the gearing I need to do. But this regulator is  giving me a trouble. I will send you a attached picture of this regulator. Do you know what will happen if I will take the voltage regulator completely out of the alternator?

thank you.

If the brush gear is not part of the regulator you can remove it. Just connect the field to the brushes but as mentioned previously you need some form of wind or speed switch to remove the field when there is not enough wind.

Look here and other places on the web for information on using car alternators with engines for battery charging. You will find very little here if you search under wind power.

I have some diagrams on my website. www.tristatewindpower.com  hope that helps.

I got your E mail but my mail server doesn't like your address.

hello,

here is the webpage you can look at it. My alternator, I am talking about is 12 V Delco Remy 63 A, made before 1987. The bottom side of the regulator is a metal directly touching the frame of the alternator.

What exactly is the problem your having?

Rostah;

You need to be a LOT more clear on what you are trying to do if you want any help.

Most of us are not mind readers so we need detailed information to reply with a useful answer.

Repeating the original question was not much use.

Generally automotive alternators are a very bad choice for an RE application.

Cheers.

To disconnect it simply switch the line to the battery. Now this varies from alternator to alternator but there will always be one ore more connections that go the battery in a car. Simply interrupting this connection will disable the regulator/ field and alternator.
