I’ll keep an eye out.  The 1800W Winpowers are fairly common.  Your parts are out there, just have to hunt them down.

I have a WinPower 1800W wind generator I need some parts for.

Power Ring - No Part Number available.  It's a sheet metal shroud, tapered with a rectangular cutout on the bottom and three mounting tabs on the small end.  It appears to be split on the bottom from the small end to the large end. 

Commutator End Bell - I-374-X.  It's another sheet metal piece, a hemispherical shaped piece that covers the front of the generator. 

I tried to attach a pic of the power ring, but was unable to.  Haven't found any pics of the end bell.

If you have need of parts, don't hesitate to post it.  This isn't my first time to post a need, and I've had good luck so far.  This is a small community, and so far I haven't seen or experienced any "price gouging."

Please contact me at charleypete1957@yahoo.com if you have what I'm looking for.  Thanks!

Joined the forum as am a small pumping windmill collector and would like to
read topics generated by wind electric members.
I have a 12v Wincharger that I am trying to restore.
Living here in Alberta Canada does not provide much in the way of parts.
Seems all the old mills have been either collected or recycled.
I have not run across any in my travels.

Historically significant, 1800W, 32VDC, Model 45 Jacobs wind turbine, combined with a Gemini Synchronous inverter and a 72-foot tall octahedron tower for sale:  $12,000.  (Note: the 22% Federal Renewable Energy Tax credit for small residential wind turbines would reduce this cost by $2640 in 2021).  This wind turbine system is complete and ready to fly again!

Historical Significance:  This was actually the first small wind turbine in the USA which was grid-tied via a synchronous inverter.  WINDWORKS, an engineering consulting firm active in the field of wind energy in the 1970s/80s, assembled this wind energy system at the Wisconsin summer home of former U.S. Congressman Henry Reuss in September, 1975.  The Gemini Synchronous inverter, invented by Alan W. Wilkerson, was the first inverter to allow small wind generators to be interfaced with utility grids.  WINDWORKS also developed the octahedron tower as a low cost, easily fabricated solution to the problem of getting a wind generator where the winds are.

System includes the following items:
Generator: completely restored.  Commutator turned-down, 94 bars undercut and polished; armature windings steam-cleaned, oven-baked and coated with an insulating paint.  Includes new armature shaft bearings and new generator brushes.  The generator neutral setting was confirmed, which minimizes generator brush arching – ensuring the longest generator brush life.  Comes with a Jacobs wind plant owner’s manual.
Flyball Governor With Blades: governor was taken apart and rebuilt.  Flyweight pivot points have new Oilite bushings, installed new flyweight pivot pins and new speed adjustment rods to ensure smooth feathering operation.  The three blades have been sanded and painted with several coats of aluminum paint similar to that used on the original Jacobs blades.  The blades and governor assembly have been statically balanced with proper blade pitch set - ensuring smooth rotor operation.
Tail Vane Assembly: custom hand-painted tail vane depicts the sun and moon on one side with a cloud on the other – looks great up in the air!  Pull-out spring, stop chain, and pull-out chain are included.
Gemini Synchronous Inverter: this inverter (serial #2) was completely disassembled, cleaned with acetone, alcohol, and flux remover, re-assembled and repaired to working order.  Included with the inverter are the original hand-drawn inverter schematics by inventor Alan Wilkerson, inverter patent(s), operator’s manual, and sales brochure(s).  Spare parts (ex. thyristors, op-amps, fuses, etc.) included.
Tower: 72-foot tall, self-supported, octahedron tower was originally designed/assembled/tested at WINDWORKS, later dismantled and installed at the summer home of Rep. Henry Reuss, and is presently dis-assembled with each tower tube numbered for easy re-assembly.  The top 7-foot tower section has been re-assembled with the original Jacobs tower cap and upper collector castings as well as the generator saddle assembly to ensure it yaws freely.  All tower mounting bolts/nuts plated with high corrosion-resistant trivalent chromate zinc to prevent rust.  Total tower weight of 1020 lbs is purported to be 40% lighter than a conventional tower of the same height.
Miscellaneous: the slipring assembly has been refurbished with three new brass rings along with new slipring brushes.  A new generator–to–slipring power cable is included with the top 7-foot tower section.  System includes an original Jacobs pull-out winch.  The turntable tapered roller bearing (Timken p/n 395-S) and lower collector casting bearing are both new.  Several articles (Milwaukee Journal, Wind Power Digest, Home Power Magazine) written about this wind energy system as well as historical photos are included.

Welcome to the Wincharger forum.  There are 6v part diagrams on the website under the resource menu, link below.  I’ll post a pic of the hardware a little later.  If it is a model 39, then it was mfg about 1939.  They may have produced the 39 into the 1940s for export.  If you can post or email pics I can verify your model.  Pics posted on the forum can’t exceed 150kb so email might be easier.  You can use the website email or my email listed in resources/part suppliers, Wind Charger Mike.

hi, I'm from New Zealand and have been given what i believe is a model 39 Wincharger which is reasonably complete. However the slip rings are missing so could someone kindly post a photo of what they look like? Also what makes the brake shoe engage with the brake drum? It was used for charging a 6v radio prior to power arriving to our area which was about 1948 so is there any way of telling it's age? It will be restored and used to power something as yet to be decided. The guy who gave it to me still uses a 12v version on it's original tower to power lights in a small shed.

Rare, 3kW, 110VDC, single-commutator, long-case Jacobs wind turbine system & tower for sale:  $12,000.  (Note: the 22% Federal Renewable Energy Tax credit for small residential wind turbines would reduce this cost by $2640 in 2021).  This classic Jacobs wind turbine is complete and ready to fly again!

System includes the following items:
Generator: completely restored.  Commutator turned-down, 188 bars undercut and polished; armature windings steam-cleaned, oven-baked and coated with an insulating paint.  Includes new armature shaft bearings, brand-new stator windings, and new generator brushes.  The generator neutral setting was confirmed, which minimizes generator brush arching – ensuring the longest generator brush life.
Blade-Activated Governor With Blades: governor and blades have never been used and are in outstanding condition.  Governor comes with three custom-designed tension springs made from chrome silicon steel to ensure long fatigue life and drop-forged speed-adjustment rods for added safety.  The three blades have a stainless steel leading edge for added hail damage protection and are painted with aluminum paint similar to that used on the original Jacobs blades.  The blades & governor assembly have been statically balanced and blade pitch set to within 0.2 degrees - ensuring smooth rotor operation.
Tail Vane Assembly: pull-out spring, stop chain, and pull-out chain are included.
Control Panel: 110VDC Jacobs control panel along with the Jacobs wind plant owner’s manual.
Tower: 70-foot tall, 4-legged, galvanized tower originally supported a Jacobs Wind Electric wind turbine plant on a farm in North Dakota.  Tower parts were laid out on the ground - all are present and accounted for!  The top 10-foot tower section was re-assembled with the Jacobs tower cap and upper collector castings as well as the generator saddle assembly to ensure it yaws freely.  (Note: tower height can be increased because made from readily available 1/8 inch thick steel angle-iron and steel flat material – will include two extra original 10-foot climbing ladder pieces).
Miscellaneous: the slipring assembly is brand-new as well as the slipring brushes.  A new generator–to–slipring power cable is included with the top 10-foot tower section.  System includes an original Jacobs pull-out winch.  The turntable tapered roller bearing (Timken p/n 395-S) and lower collector casting bushing are both new.

The model 36 "utility" model didn't come with an air brake governor so it relied on the tail folding action.  There is about 1" of offset between the generator yaw axis and the tail pivot.  If you look at it from behind you can see the offset.  As pressure builds on the area that the propeller sweeps, a torque is produced that causes the prop/generator to pivot out of the wind.  The tail maintains its position relative to the wind.  This method of governing is very common for water pumpers.  On the model 36, its crude because tail pivot can have a high friction.  The "deluxe" model 36 used an air brake type governor and the tail folding was then used primarily to turn the unit off since it doesn't have a drum brake. Maybe the deluxe model used a stiffer spring so the air brake governing dominated.

Hello,
I have spent much time trying to figure out how the model 36 governor works and just don't get it. I searched the forum and did not find an answer so am hoping someone here can help out. When the blades to a speed that needs them to be governed, what causes the tail to fold?

Thanks for the help,
Greg
