What about this motor

[flory7]

I just picked up 10 of these motors. Yes, they are small than the usual wind generator motor, but smaller is better in my location (I live in an alotment). They are made by Hansen Corp. and are from ATM's. They should ne 24V @ 360RPM. Who can I mail one to that could test it and give me some better info. I do not know amps. Shaft is 3/16" X 7/8" long and motor is 2 3/4" X 1 9/16 not including shaft. Let me know an address and I will send you one to play with. I was thinking of making a few small 1 foot prop style or making some anemometer type wind generators. Let me know if I am goofy.

Yes, you are goofy.  Me too. ;-)

You got 10 from an eBay guy in Akron?  Me too.

Sorry, they just won't make 12V.  They only make like 3~4V if I recall. Take out 0.5 or so for the blocking diode and it leaves almost nothing.

They might make enough to charge a pair of AAs.

However, they seem to be nice motors on 12V, about 110ma unloaded.  Maybe a desk fan or something.

Thanks ghurd,

   Well I guess I was the only one to think they would work. Shoud I take them back and kick the guys @ss? I hooked one up to my drill and was getting over 24v I think. I was using a cheap meter. Even with low amps I would be o-kay for lights

[ghurd]

Hold On!  We have different motors!

Mine only made a few volts in a drill.  Sure sounded like the same motors (10, Hanson, 24V, 360 RPMs, size...)

If you are getting 24V in a drill, your motors are better than mine!

Connect it like a treadmill or Ametek, with a diode, and ammeter, connect it to a battery, spin it with the drill and measure the ma into the battery.

Probably be nice for 18" dia PVC blades, or maybe 'ruler blades'.

No, you were not the only one who thought they would work.

That's the same reason I bought mine.

You know, I only fully tested one, didn't try a second one because the numbers I got were so low.  Maybe it was a bad motor?

My meter must have acted up because now I get 3-5 volts. I get 5 with drill at full speed. I even tried the "new" one that he threw in ang got the same. I guess I will just break down and pay full price for a full sized motor.

Can you take five or six of them and connect them in series to get something useful?

Or maybe you could make some stake-mounted wind turbines to charge some yard lights.  You can buy some of those duck wind mills and make them charge up the lights in the garden.  That should look nice.

The coil resistance would be too high to get any power out.

A single 99 cent stepper motor would make more 12V power.
