Playing with wind power

[J57ltr]

Well I scrounged aup a few parts. I had an old motor laying around, it's a NEMA 17 that the control baord went out the gear on the back is actually the incoder gear (it basically has a tape head as the pickup), and a bunch of prototype parts when we originally developed our small conveyor. The SST thing with the pulley was a jackshaft for the first system I have 2 of these and they each have 2 1.4" ID 3/4" Od bearings in them I may use them as the top and bottom of the assembly. The motor will generate about 12.5V at about 600 RPM on 2 of the phases I need to do a little more reasearch on the way it's wound. I had 2 wires that I could get 12.5V and only about 2.3 on another pair. like I said i'll check into it, (its a stepper motor). I am going to remove the 3.. screws and add longer 4-40 screws all the way through so that I have 1/2" long 4-40 screws. (we do a lot of mods to these motors to make them water resistant. The other gears I can get anywhere from 1:1 to 4:1 in a single overdrive. I'll show the guts later when I take more pics.

I also bought 6" diameter stove pipe that I will cut in half it's perfect at 24" tall and I think will work fine, I may need to add some support since it's only .030" thick.
