My 17' Turbine so far
willib:
Thats a nice turbine!
curious of the outer diameter of those rotors?
freejuice:
Nice!
I really like that setup!
Wow 100 feet up? I was looking at mine the other day and thought of adding 20 more feet, its already at 65 feet and looks like its really up there!.....100 feet.... I'm green with envy!
I think I will stay below the clouds :D
Those anchor points should not give you any trouble!....4x4, thats over a cubic yard of concrete per hole....you've got some weight there!
More pics are required as you continue your fun! ;D
nekit:
Here's my specs. Hopefully it will work out well.
It's a 17' dia Grid Tied unit
Stator:
12 coils wound 118 turns, one in hand of 14 gage wire wound to the "Otherpower" design. I used a high temp epoxy resin and it has cooling holes in the center of each coil.
Magnets:
32- Neo 3x1.5x.75" countersunk bolted down with cs stainless bolts and stainless band around the rotors. Rotors are 1/2" thick 18" dia with cooling holes.
Yaw bearing:
4" tubing with bronze bushings and grease fittings. I also used a thrust bearing on top of the Yaw shaft, that is a throw out bearing from a Ford mustang
Generator Mount:
12" forward an 10" offset
Wiring Yaw Head:
This is a used unit I removed from an old pivot irrigator.
Tail mount:
I made this adjustable with three sets of holes at 10, 14, & 18 degrees. The tail pivot has bronze bushings and grease fitting.
I also add an adjustable shock that is a after market motorcycle steering staibilizer to cushion the tail movement.
The curved tube is for a cable that will pull the tail in by a small hand winch at the base of the tower.
Tail:
The tail is made of thin walled chromemoly tubing to keep it light. It has bungs on the end that I can add weight as needed.
Blades:
G-222 profile carved by Royal Wind from Ash wood.
Tower:
I am currently building the tower . It will be made of 8" x 1/8" wall tubing. It has two 45' sections and one 10' top sections and a 43' gin pole.
It has a removable 10,000# truck winch that I can take in when I'm not using it
nekit:
Here are the controls specs:
Inverter:
Power- One Aurora PVI-6000 grid tied inverter
Control Box:
Omron k8ab-vs3 voltage adjustable relay that switches a Telemecanique LC1D258 contactor on and off. This system switches on a 6000W dump load when the grid goes down and when the voltage goes over 450V.
I also have a Telemecanique gv2me16 motor controller in the 3 phases from the alternator. If one of the phase get disconnected or shorts, it will disconnect the entire alternator.
At the tower I have a 3phase switch that will work as a shutdown switch by shorting the phases.

Nekit--Nice build. Your attention to detail will motivate lots of us.
Welding is nice, Tig?
Thanks for sharing
