Does anyone have any step by step guide to doing this?

Step 1: Sell alternator
Step 2: Use the money you get from the alternator to buy a motor.
Seriously; tell us what you are trying to accomplish and perhaps we can be a
bit more help.
If this is for some "over-unity" experiment, please leave out the hompower
and renewable groups in your future postings.

Permanent magnet motors are in the $00 range now. This defeats the
purpose of low cost setups. Alternators can be used in many applications
that require DC motors. An alternator can be converted for under $00.
Making stators for wind generators is way too time consuming, plus is
has to be done exactly right. I figured that an off the shelf Delco 12si
can do the job better, and at much lower cost.

The only sort of wind generator I know of that requires a motor is the
sort that lifted Marilyn Monroe's skirt.
Of course it would never have occurred to the manufacturers of wind
generators that they could do their job better and cheaper with an
off-the-shelf auto alternator. What were they thinking? :)
If you want to use such an alternator to generate 12V DC power from
wind, it doesn't need any converting just tie a propeller on the front
and run it up the flagpole. If that's not what you want to achieve,
then you'll have to be more specific.

I'd like to use it as a motor. It can power a bike, go cart, etc. Those
motors that currently come on scooters are cheap made in china trash
that tend to burn up without that much effort.
