I want to reveal to you how I constructed my own wind system from start to finish.
Here is a list of materials that I used to get started.
I purchased a DC permanent magnet motor from eBay.
The motor is a 48 volt dc motor that as an rpm rating of 2000 rpm, which means at 12 volts dc it, has an output of 5.
8 amps at 500 rpm which is ideal to charge a 12 volt battery system.
I decided to make my wind turbine out of PVC pipe which is readily available at your local home supply store.
The diameter of my motor is 3" so I used 3" PVC pipe so that I could slip the motor inside the PVC pipe.
First I quartered the 3" PVC just enough to allow the motor to slip in the PVC easily.
Now that I know how to easily slip the motor in the pipe I used 2 large hose clamps to secure the motor in the PVC.
Next I needed a way to allow the wind turbine to pivot freely in the wind, so I got a 3" PVC tee fitting.
However, I decided to use a 2" rigid mast for my tower which allowed me to reduce the tee fitting down to 1-1/2" PVC pipe which slips nicely into the 2" rigid conduit allowing a smooth turning point.
Now I am ready to fabricate my turbine blades that will turn the motor in the wind.
I used a piece of 6" PVC schedule 40 white plumbing pipe, and I cut it into 3 equal pieces 36" long.
These must be cut exact so that very little balancing will have to be done.
To be honest with you it took me two tries at this to get it right.
Next I decided to use a piece of 2" PVC for a tail section.
I made the wind tail section out of a piece of Plexiglas I had, approximately 12" high and 24" long.
I split the 2" PVC 24" long vertically to allow the piece of Plexiglas to fit between the PVC and drilled through the PVC and the vertical tail section so I could bolt it securely in place.
You must balance the tail section with the motor installed in the 3" PVC so that it balances at the pivot point of the 2" rigid conduit allowing smooth turning.
I had to cut off my 2" PVC until it balanced perfectly.
One problem that as always been a part of a horizontal wind turbines is called wire twist, were the constant wind change of direction will cause the wire to twist and eventually brake.
To solve this problem I devised a simple stop system by drilling a hole through the 1-1/2" PVC just above the rigid conduit, with a 1/4" hole.
I placed a 2" long 1/4" bolt through the hole securing it with a nut and lock washer.
Next, I placed a 3" piece of 1/4" rod or bolt secured vertically to the end of the 2" rigid conduit, spacing it away from the 1-1/2" PVC so it doesn't rub.
I secured the vertical bolt with 2 hose clamps around the 2" rigid conduit.
Now you are ready to attach your wind turbine to the tower and wire everything so you can start producing your own electrical energy.
I realize this is just a glimpse of how I built my own wind turbine, but it gives you a starting point to build your own.
I have a guide that I used available at my website.
