I'm sorry if this sounds a bit abrasive, but for your own good I'm not
going to tell you, on the basis that if you don't know the answer
yourself, you shouldn't actually be playing with this - you just don't
have enough basis knowledge to be setting up something which is
potentially dangerous - go with the Ebay suggestion.

"Dangerous"?!? God - you should see some of the other hobby pursuits I've
"played with" over the past 50 years! Now if I had said I was trying to
build a flying machine out of timber offcuts or something, then I'd have
said your response was probably wise enough.

Spin the motor shaft & see if you get power out of it. Also see if it
runs round easily or has a friction problem. It sounds like youre
looking for a cheap solution, car alternators fit that, though they do
lose power in the energised field winding.

Don't forget a brake mechanism too, on occasion a turbine will need to
be stopped and kept stopped.
