Designed to fit onto the very standard and popular 1-1/2" schedule 40 pipe.
All parts are made from steel.
- FP-640 mounting and pivot bracket
- Tail boom
- 2 retaining collars
All parts are in painted.
What else do you need?
- FP-640 Alternator
- A set of blades from 48" - 72" diameter
- 1/4" plywood for the tail fin, approx. 16" x 16"
Assembly is straight forward and simple. All parts should be painted for corrosion protection.
Mount the Alternator to the main pivot bracket with the 3/8" bolts and lock washer provided.
Make a fin for the tail boom from 1/4" plywood. It should be about 16"x16". Mark and drill holes to mount it with the bolts provided:
Bolt the Tail Boom assembly to the main pivot bracket:
That's it! It is ready to be mounted to you 1-1/2" Schedule 40 pipe.
Use a locking collar on top and on the bottom to retain the wind turbine to the pole. It will easily "weather vane" into the wind by itself, but we use a touch of marine wheel bearing grease on top of the lower collar to make it spin even more effortlessly.
We secure the power cord with wire ties and feed it down through the tower.
No slip rings required!! Even after several years, the cord inside the tower doesn't get twisted. At our location, the wind normally comes from the west and north and rarely does the wind turbine spin around the pole.
That's it! Just mount a set of blades and you are ready to produce electricity!
The shaft on the FP-640 alternator is 3/4".
We do not sell blades. There are many online sources that offer them and a quick google search will generate dozens of sources.
What's the output? It depends on the input...or wind speed and blade size.
With a 60" diameter, we typically see power in the 300 watt range. Again, it depends on the wind speed and the power constantly changes with puffs and lulls.
We cover the details for making tis calculation here: Wind Power This will also help you decide what size blades you use based on your wind conditions.
Have fun with this exciting project!
