Does anyone know how to wire a full wave rectifier to an alternator to create a motor? Answered

I want to use the alternator off of an old (wrecked) car as a motor but need to know how to connect it up I have heard that you can use a full wave rectifier to do this, but am uncertain as to how to do so.

Isn't google working in your part of the world?

Rick there are a lot of sights that tell you, you can do it.

But they don't tell you how.

Although that is true there are also a lot of places that do tell you how OR offer to sell you the information.

$19

Says it is a how to.

I know it may take some time and effort to go through all the alternatives but why should that be my time and not the questioners.

We seem to have shifted from providing assistance to people who are already into their project to solving the basics for many who haven't even made an effort.

Its fascinating, and very interesting. I bought the book yesterday.

Even if you do accomplish this, the motor would be extremely inefficient due to the fact that it is designed to be driven, not drive. It has a lot of stator weight, and would require an extremely large amount of current to start up, not to mention have a high load current under use. However I suppose it is possible and could potentially produce a 1/4 to 1 horsepower motor, if not higher. I will look into this right now and post what I find.

Spend the $19, I think its highly viable,

Steve has the right idea.

You put 12 volts DC to the armature.

Then you take the rectifier out of the stator and apply 12 volts 3 phase AC to the stator.

An alternators stator is wired like the first pic and you need to wire the stator like the second pic.

I don't think its feasible. An alternator needs DC on its armature to generate AC. To make it work, you'd need to drive 12V AC into the fields, and DC into the armature.

I very highly doubt this project is important enough for you to shell out money to a company for a manual, but if so http://alternatorconversions.com appears to have one which is extremely in depth, if you want to check it out? It is something like $19 for a digital copy.
