Jacobs wind generator

Heres a link to the Jacobs wind generator I rebuilt. Been using it everyday since May. Very impressed with it so far.

Poor quality video camera.

That looks fantastic, I have to agree.

Thanks especially for the shot inside the governor.  Seen from the outside I inferred something like that mechanism in there, but couldn't be sure.  I'm sure other members that like discussing pitch control will appreciate it too.

Please tell me what you were trying to show on the LCD display.  RPM?  Was it reading a range of 100 to 200 or so?

No one believes the theory except the one who developed it. Everyone believes the experiment except the one who ran it.

Great Project.

I've been keeping an eye open for one of these old machines, but they are rare to come by.

Thanks for the comments, Yes Boondocker these are getting hard to find. I've found a few 32 volt ones which would be good for a 24 volt system. But the 110 volt ones are rare. i guess not alot of people wanted to look after, or could afford 55 batteries!The 110 volt ones were more common for small towns and villages for street lights and the dance hall.

Sparweb,   The inside of the governer is a work of art for sure. For being built that long ago I was amazed when I pulled the cover off and everything looked like new!

On each shaft inside there  is an inner and outer tapered roller bearing, that you can grease. The shaft never makes more than a third of a turn as it twists the blades, but they never used bushings.

When I first erected it, at slow speeds I could hear a click evertime it went around, drove me nuts.

I had one outer bearing that was a bit loose so decided to replace it, the bearing shop talked me into going to a greasable ball bearing rather than tapered roller. So I ended up replacing all 6 bearings to ball bearing type.

When I had it all apart I found my click. In behind one shaft was a teardrop shaped weight they used at the factory to balance the governer. The threaded bolt holding the weight on had loosed slightly to let the weight rock back and forth against the side of the houseing.

The out of focus meter you see is trying to show 42-43 amps, thats what it was putting out that day at about 60 volts. I think the meter has a range of 0-150 amps or so.

At only 22 feet in height there are very few days this generator is stopped, it seems to be always turning and always putting something in the battery bank. I cant wait to get it up to 60 feet!

Shawdow,

did you re-wire the rotor for 48vdc?

Yes, It was very simple.

The field coils are all 6 wired in series. I found the center wire and snipped it to have 2 sets of 3 field coils to cut the voltage in half.Then paralled the brushes to have two sets of 4. So now I have 1/2 the voltage but twice the amps.

Very awesome Shadow

A nice piece of functional history restored , and it looks real sweet too :)

Hey Shadow,

Very nice job on the old Jacobs.  My project is moving along, though a little slow.  Finished the bearing / slip ring yesterday.  I should be able to paint everything this weekend if I can get the time to buy the paint.  Still scrounging up wire for the 140' tower.  The Breezy was wired with 8 gauge, sufficient for 30 amps.  I need minimum 6 ga, preferably 4 ga for the distance (140' tower, 90' to the garage) for the Jacobs.  I've finally added "Wind Power" to my website and uploaded a few photos.  Will post a lot more on the Jacobs soon.

Shadow,

What did you use for the furling system as far as cable or chain?  Did you install a swivel?

BTW, seeing you up on the tower for the install was pretty cool.  There's no way you would catch me that high off the ground, even strapped on it!!

Yes I used the original furling chain and swivel. Originally they used solid wire from the swivel (just below the slip rings) down to the winch. I used cable.

That high up..is only 22 feet!  This still has to be mounted up to 60 feet. I'm dreading that.  I'm not good at heights... I dont even like being this tall.

So that's why your painted unit was on such a short tower!

lol, yep.. It only needs to be that high! Notice not a tree for miles.

Actually that one went on a tilt up lattice tower to 60 feet.  But the Jacobs is too heavy to try tilting.

I have heard it said that putting a old Jake on a tower  is no worse than changing out and engine in your truck
That is if your truck is  fifty feet in the air ;)

As I remember they weigh in at over 400 pounds.
Having so much fun it should be illegal

Yep, youre right 440 lbs total weight. But it does go up in pieces so that helps.

Nice picture of the install.  Obviously from someone that liked the ground better than climbing.  :)

Doesn't look like trees are a major issue at your location.  Where are you located?

We are in Southern Saskatchewan, Canada. About 100 miles north of the  Montana Border.

I just read we are the third I think windiest places in Canada. We are surround by large wind turbines. 90 some about 20 miles south east and another 40 some to the west.

Come to think of it, they are gonna block all my wind for the Jacobs soon.

Shadow,

I talked with a Breezy owner in Saskatchewan just after going live with my Breezy and he was really happy with his unit.  In November of 2008 he saw $80 of electricity generation.  He was inquiring if I had written plans for my 140' tilt tower (I don't) because he was installing a 10KW unit from Breezy.

Are you sure you don't want me to send you my grounded 5.5kW unit??  ;) ;D
