rclewis01Great job and excellent video. Thanks. A real quick question. Do you need a diode in line to the batteries? Also I was wondering what size of pipe did you use for your blades? Do you recommend a certain size?
I’m showing that motor to be 38 VDC, 12 amps, and 1150 rpms. My DC motor analyzer says you should be using a 4.5 foot diameter blade..but 4 foot is good too. In theory you should get about 10 amps in a 20 mph wind going to 12 volt battery. The motor could push up to 500 watts in about a 30 mph wind.

ajonateThey are 24″ each, which makes the overall blade span just a little over 4′.
I didn’t make a point of it in the clip, but I used ABS pipe to make my blades instead of the PVC pipe that most wind turbine builders use. The ABS is a little more flexible, but ABS stands up to sunlight much better than PVC. The fact is that ABS is so stable in sunlight that it’s even used for certain auto body parts.

larrylawrencejrThanks a bunch again for the information. I like how you show everything in your video and really do appreciate all your efforts. I am going to order all the parts you did and I plan on trying it with my Ametek 38v as soon as the parts arrive. ]]>
ajonateI got the large pulley from Home Depot in the evaporative cooler scetion. I believe it was a 12″ pulley. ]]>
ajonateSure. I got it at Checker Auto Parts locally. The belt size is a portion of the part number. They know how to give you a 40.5″ belt, or whatever you need. ]]>
larrylawrencejrThanks for this video! Great job! You know I could not find anything from anyone about using geared pulley setup. You are the only one I could find. please post more info on the pulleys and belt used as well as their sizes and where others can purchase them. Again, thanks for the video and keep them coming if you get time. larry ]]>
ajonateYes, I’m using a diode. It’s inside the power shed where it connects to the batteries. Actually, I’m using two 6 amp diodes in parallel.
I used 4″ ABS pipe for the blades. I cut so that the tip was about 1″ wide, and made a straight cut to about 3″ before the connection end. The overall diameter is very close to 4.5 feet, since the blades themselves are 24″ and there is some open area at the hub.
