Test setup : Automatic Active blade pitchcontrol.
Constant speed system.
The electronic circuit is connected parallel with my consisting windgenerator.
The actuator is pulling back in decreasing windspeed.
In high wind above 330 propeller Rpm it's going the other way.
Controlled by an Aruino MC. And software programma.

Frans, you should seriously think about putting all that in one package and selling them or licensing somebody to build and sell them, maybe a complete package with the hub and blade grips and the whole ball of wax.
I'd but one to play with for someone like me that does not have a background in electronics it might as well all be in Latin. ;)

Hi Fabricator.  If there is a demand for it I can make it.I have the gear with UV light and acid bath.This circuit is made on Veroboard and that's not proffesional.Spaghetti wiring on the backside. Should make an etched PCB. Saves a lot of time. This circuit is for mbouwer. He is making  his own mechanical design based on the 3 meter prop diam Piggott.
Menelaos is also making one. For the time now it is experimental .

We wish you and all Fieldliners a Happy New Year.

Cool, it will be good to have several working models to get all the bugs worked out. Happy New Years to all you fieldliners across the pond too. :D

Wincharger modified blade pitch DIY


 With implementation of the Rural Electrification Act in 1936, however, the wind-powered battery chargerís days were numbered. Even the most remote farms had access to electricity by the mid-1950s, ending the need for the wind generator and a free energy source. Many utility companies refused to provide power to farms with working wind generators, and more than a few Winchargers were deliberately disabled by high-powered rifles.

I got a 6V Wincharger Airline Deluxe but it needs a new blade.  Every farm back in the 1920's - 1930's had one of these too:



That one is a 32V Delco Light Plant.  But they also made them in 6V.  There was all sorts of 32VDC appliances back then, including light bulbs, clothes washing machines, sewing machines, clothes irons, and even shop tools like drills and saws.

The REA was basically a government subsidy for electric companies to build distribution lines to rural areas.

My dad was 16 years old when they came to my grandpa's farm to run the powerlines there.  My grandpa had bought the Wincharger in 1931 when my dad was 10, and he refused the new electric service.  That Wincharger ran on our home farm until 1968 when the blade broke on it.  I have the Wincharger and the Zenith tube radio that came with it, and the radio still works.  My grandpa paid $10 for it.

Wondering for what price you can buy a remanufactured Wincharger nowadays.

Thinking of a real good design:
The new 20 pole, 15 coil CAD with active pitch control.

Active pitchcontrolled blades

Works like the big windmills .  Reliable 3 years now.

This is a fantastic design, the options for control are endless with the right circuitry. 

Kudos.

Can we say active pitchcontrol is booming?

A lot of progress in the development of active pitchcontrol.
Variable pitch propellers and micro-controllers.
You can create an invasion with a 1000 drone squadron.
The technical application we use to control our windmills is simple.
Can be booming.

We would like to find out if implementing the drone pitchcontrol on our windmills is possible.

There are RC servos that can do the job.
Torque : 12,8 kg / cm  6volt . metal gear and ballbearings, compact dims.

Hi All.
I am living in Northwest Holland . Average wind 5-5.5 m/sec . Building windgenerators several years .
Have some experience with making blades ( fixed- and passive pitch and active pitchcontrol )
I see that some of you ( Menelaos ) and other friends on Fieldlines are thinking about pitchcontrolled blades .
For the time of 3 months I have running a DIY active pitch controlled windgenerator.
Must say I am very content about it .
It is controlled by an actuator wich can be switched automatic and manual.
Blade angle from zero to 90 degrees in 8 seconds.
Propeller diam. 290 cm .
Controllable max speed 330 rpm . (adjustable)
Feathering and electrical brake in case of storm.
Generator disc type ( Hugh Piggott design ) 9 coils and 2x 12 neo magnets. 24 volt.

I see some advantages : Never overspeed , No overheat stator, No dumpload , No overload of batteries , controllable voltage and amps for inverters for batteries and grid tied ones. No material stress. With extra sensors No voltage controller.

  Wow! this truly is a labor of love.  Midwoud1, what can you not do?  and to the people pitching in, you guys are awesome.  Thank you for sharing this thread.  This is an inspiration to me.  Will be looking forward to following this thread.

Hi Lance.
Welcome to the forum.
Please some info about what you intend to do .
Battery charging or grid tie ?
Start with a basic design , or active bladepitch ?

We want to use a simple worm gear drive.
Here is the welded wormweel.

Rinus,

Is the goal to optimize tracking of the wind, or to provide a means of turning the turbine out of the wind for regulation?  And, if the latter, are you thinking this would be in lieu of variable pitch blades, or in addition to it?  ~ks

Kitestrings,

We are searching for a simple implementation of a low weight, steered yaw bearing.
And we always want to be able to master the turbine so we think we need pitch control.

After this ballbearing we would also like to make a slide bearing implementation.

We have made the base ring for the slide yawbearing. Worm wheel is part of the construction now.
