"SSG S" needed a controller. We emailed a bit, and he sent photos. He is not familiar with forums. I told him he would enjoy this one, and we would love to see his windmill.
I offered to post this, he agreed, the military approved the photos, and here it is!
"SSG S" with his creation made from the recycle bins.
The only items purchased were the magnets and controller.
The tower is very short. It is a good idea to place short towers on a treeless `hill'.
The next time someone asks about placing a small windmill on their garage, we should ask
"Exactly how big is your garage?"
The wind sock points to the windmill.
The blades remind me of fine furniture!
It is a single rotor with laminations made from pallet banding.
The stator is a bit on the small side. Small is not easy.
That is a 9V battery!
Technical information...
A 12V system, 9/12 single rotor with laminations.
Blades are 4.5 TSR.
Magnets are 1 x 3/8 x 1/8" on a 4.25" diameter disk.
Coils are 96 turns of 0.020 or 0.022" from an UPS transformer.
Wired star.
Makes 1 to 3A in a good wind.
A few pieces Non-Technical information...
This is his first windmill. He had no one to answer questions.
The stator shown was an upgrade.
The "grid" generator failed. The power went out.
SSG S had light over his work area.
He told me "I had some real limitations with tools available."
And "It was a real challenge."
My response was "No Sh-t?"
He didn't believe it was overly interesting. He may like to know someone other than me is interested.
Bad News. The windmill was taken down and is not flying.
Good News. SSG S has done his job and is bringing the windmill home to fly in American wind.
Thank you SSG S.
Be proud of ALL your endeavors.
