Wyatts 12 Footer
« on: January 23, 2009, 07:46:56 PM »
This generator is a 12 foot, 24 volt, 16 mags on each disc, 2 x 1 x 1/2 . Its a 3 phase, 12 coils, 2 in hand 16 awg, 50 turns per coil. The tower is in a excellent area on top of a hill. The mill is turning most of the time, day and night, 10 amps mostly all the time, 20 - 30 amps in normal winds. It shows 50 - 60 amps for short periods when the wind is blustery and changing directions.




This machine has 7 3/4 inch offset and 18 degrees on the tail hinge. It spends much of its time fully furled. I used a 6 foot tail boom, instead of the 8 foot tail boom, because it was installed in a very windy location. I had to add 8 lbs of weight to the rear of the boom, after 1 week of observation. The tail fin is PVC 1/4 inch thick 4 foot tall and 2 feet wide.




It's on a 90 foot tilt up tower, 5 x 5 inch square tubing, with a 50 foot jin pole. There are 3 sets of 4 guy wires 1/4 inch thick on the mast. Three conductors down the pole are #4 cable going to the rectifiers 120 feet to the battery room. My slip-rings on the top take care of the cable wind-up.




Wyatt has 12 batterys, 2 volt each configured for 24 volts. Each battery weights over 400 pounds and has 2100 amp hour capacity. They are connected to a 4000 watt sine wave inverter.






Wyatt warned me early on that he may have to have a larger generator, if this one was not going to do his job. Well,I got a call today to construct a larger one. Watch for my next post in a few days titled "Wyatt wants more Power"

Wow very nice looking system, and on a good tower.


Are the blades attached to the hub with some kind of steel extensions? (looking at the first picture).

Nothing's as easy as drilling a hole in the wrong place

Hi Janne, Yes, I used a 14 inch steel prop hub 3/8 in thick, added 3 extensions 13 inch long, 2 1/2 inch wide, 1/2 inch thick. 3 inches of the extensions are welded on to the steel hub. I used 2 steel plates, one on each side of the blade root, to attach to the outer extension. I got the idea from my Whisper 1000. The extensions have not effected the preformance.

Mitcamp,


Thanks for the great presentation, really enjoyed all the effort and the pictures.


Do you suppose you'd be able to let me know ( skipb@greatlakes.net ) more about how you made or where you might have gotten your slip ring set up? That was really cool and I'd sure like to see if I could incorporate something like that into my next project?


Thanks again for the great information,

behoof

behoof, this slipring setup is made with materials you can get locally, the stand is pipe fittings from the hardware store, the brushes are starter brushes from any automotive supply. The brass rings are made by a local machine shop. The rings are fitted with a press-in collar to insulate the ring from the metal pipe that supports it.I will try to add a link of a exploded view. http://www.fieldlines.com/story/2007/4/14/0154/34166


My photo of the sliprings is at the bottom of this post by cdog. If this link fails,you can check my uploaded pictures regarding slip-rings in my user files. If you need any more info, shout again. I must point out these sliprings must be covered to protect it from the weather.
