First of all I need to thank Wilbur and Flux for bailing me out several times, otherwise this would still be in the basement. I wanted a 18 inch Dual Axial Rotor,24 mags each rotor 2x1x1/2 18 coils,3phase,12 volt. I have 12 batterys, 2 volt each and hooked up to serve 12 volts. Each single battery weighs 250 pounds and has 1075 amp hour capacity. Hooked the way they are,gives me 2150 amp hour capacity. I am like everyone else out there and wanted more power. Well now Ive got it and found out this puppy can put out some juice when you get some wind. I had to keep it braked alot of the time. I now have 3 C 60 Trace controllers in my panel hooked up to 4 600 watt 12 volt water heating elements. I used a 40 gallon electric water heater and added 2 more heat element ports. It now has 4 elements in the tank. I am going to add another tank,with 4 more elements very soon. I will put a picture of this tank in my photos next time I,m on here. This dual rotor is spinning 3 wood blades, 8.5 feet in length with a over all radius of 18 feet and I believe I will built a bigger prop, 10 foot each blade before winter comes. My 18 coils are wound with 4 in hand 14.5 gauge magnet wire, I think it was either 25 or 28 turns. It kicks into battery voltage,at 72 R.P.M I have doubled up on the rectifiers, so I have 6 rectifiers on a large heat sink. I have it wired with 2/0 battery cable. I am going to build a new 24 volt stator for this machine and change my whole setup hopefully before winter comes. You will also notice in my photo,s that I use a slip-ring set up on my machines. I doubled up on the brushes on this particular machine and may add a third set if it requires them. I have been building my own slip-rings and brushes for 7 years. These slip-rings are brass and heavy at 3 pounds each,2 required and are seperated from one another with high tempature teflon bushings. My brake switch is made with 3/4 inch copper pipe. I have had this machine up for 3 weeks and it starts charging at 8 m.p.h. Normally we see 8-14 m.p.h winds and I see 30 - 100 amps. Since it,s been up on 2 occcassions, the wind gusted up to 25 mph and it furled showing 200 amps and then my digtal meter went over its rating and blacked out. The meter came back on after the wind quit, so I ordered another meter that will handle more amps. I plan to build another Dual Rotor this winter. It will be of higher voltage,probably larger magnets and bigger disc.I have also ordered another set of batterys. Any body got any ideas. Thanks again Wilbur and Flux. Mitcamp signing out
