Nice looking motor but will likely have to be setup with a 2/1 or better ratio system to get adequate rpm(s) for 12-volts and above. Most treadmills will not reach 12-volts as a direct drive system unless you have very strong winds.

@Pbeas52 Thanks for the comment. Check out my new video, Second Attempt. It's bigger, greener, and geared up now. Shots with meters hooked up.

my treadmill motor is virtually useless. it can only generate 8-11 volts during gusty winds. it manage to hit 18 volts during extreme weather but very inconsistent. voltage below 12 is simply rubbish . No way can it charge battery.

I am looking for some blades to produce. The material is abs simular. So i can rotocast in a couple of minutes. But first i need some blade designs to evaluate and make a mold. I have a 7 foot capability on the rotocaster. Go to matchbook69 and scroll down to rotocaster

@matchbook69 The blades on this video broke at the bolts when it tipped over. Oops. I made longer ones out of 6" pvc and the edges turned out much better because I made a jig for the router table to round the leading edge and sharpen the trailing edge. I only tried it once and didn't have a pole to mount it on so I took them off and made a vawt. The blades are in the basement somewhere. A while back I trimmed them so they all weighed the same, but haven't tried them since. Would you pay s&h?

@matchbook69 I'll see how much shipping would be for you to get it there some time this week. Maybe I can send the small and big ones for you to check out. It would be neat if you could duplicate one of my big blades and send them back when done. I still might try them out someday.

how are you planing on keeping it from twisting the wires off as it pivots in the wind

mosbysmen 5 months ago

@mosbysmen You just use a hollow tube to mount it on and run the wires down the center of the tube. It would have to twist quite a few times to mess that up. Thanks for the comment

Hi, Sweet project. I kinda stayed away from platsic blades after reading alot a bout them.

i made some in wood, they do the trick nice. keep it up tho .

GL.

@ThePJpatch Thanks for the comment. I knew that pvc blades would eventually break but I didn't think they would break the day I put it out there. That was my fault because I got antsy and set it up on an old lamp and it tipped over. One of these days I might give it another go but the motor is under the tire of a bicycle right now. When charging my battery through a diode I pedal around 14 volts and it draws about 3 amps of current. Charging 2 batteries makes it too hard to pedal.

Are you a pilot? Because the job you did in making those props out of PVC was really a fantastic job. As soon as I saw it working and saw how you had the set up hook up to the lexan I thought "he should try to make a dual reverse prop generator." But that's just the OCD in me talking. LOL

@OCD450 Well I have flown a 2 person plane one time many years ago. I made these blades after watching many you tube videos. I did the edges with a sander and finished them up with sandpaper by hand. That took a while and didn't turn out as good as I would of liked. Recently I made three bigger blades out of 6" pvc and made a jig for the router table that produced amazing results. The leading edge was nice and round and the trailing edge was very sharp. I'll have to post them. Thanks.

Great video, have got 4 windgenerators made out of treadmill motors at most all I could get out of them was 6 volts under a load. Have got some treadmill motors geared 4to1 and 5 to 1.which works very well.I'm working on 2to 3 treadmill motors on one windmill . 2 treadmill motors should work great geared up .But it takes a good amount of wind or large blades on your wind generator .Ceiling fan generators works good enough to charge batteries but not alot of amps.

Thanks. I sat this out in the yard with some weights around the base and when I wasn't looking it tipped over. All three blades broke off. They were 24" long and 5" wide. I made new blades out of 6" pvc that were 30" long and 6.5" wide. I put aluminum strips on the flywheel to attach the bigger blades. It had more torque but was no where near 12 volts. One day it was spinning about as fast as I felt comfortable with and only produced 5 volts with no load. Now It's under a bike and I can charge.
