I like the way you're thinking Outlawstc but I'm thinking more 3 dimensionally.  I did post regarding vic in another thread.

There is lots of stuff to discuss about the RVIC here if you wish to jump into that ;)


Ok, coil winder is ready to go! I did a test coil of 50 winds.  I will start winding my coils tomorrow, and then get them in the stator.

Looking good, Donaldwfc!

Secondary #1 Finished...

My counter doesn't work for some impossible to figure out reason, I had to count to 50*12 by myself...

This... is delicate work!

good work don, im right behind ya...  today i managed to get my jig around 90 percent done, just need to notch out a slot for the zip ties.. i will try to post a pic of my version tomorrow...  i just need to do a few more things and i will be winding.... while back ago i found a decent deal on small zip ties on ebay.. i got like 1,000 for around 3 or 4 bucks, ... i think my dia is around 2 1/4 i havent decided the wind count yet for my 27 awg ...   i havent really looked into diodes either and im up for suggestions.....    i plan on replicating his board and prefer the same style diode thats  on the board.  im also in the process of making a insulated tube cell.. donald for this rotary style what style are we looking at for the resonant cavity??? do we need to meet any capacitance values? any certain arrays?

When you make your jig, aim for a 1/4 inch gap on both sides, not just a single cut, because you need the room for your zap ties.

2 and 1/4 might be too big? mine is just less than 2 inch diameter, but as long as you play around with some test coils and figure out how much room you have.

To figure out the turns, I made some 100 turn coils, I could fit 2..3... 4 of them in, 400 turns per window, but then I didn't have room for the overlapping phases, so I figure 300 turns per window, and everything will fit.

Make sure you test these coils in the stator and in the alternator... make sure you have room in the case without hitting the diode board or anything else.

I might replicate the PCB after I get it running, first I will build an aluminum heat sink and mount the diodes on that... wire everything directly.

I am going to test this on my (only) Demonstration Cell... and I was thinking it may work better on a larger tubular array, like Stan's.

I have been working on a design for a 3" delrin resonant cell in the back of my mind. I'll start to think more about that after I get this project done... I also have thoughts on the variable plate spacing cell which I think would be neat and useful to build too...

After the RVIC is wound I suppose you could find the Inductance, and calculate the frequency output at whatever rpm you are using, and if you had a variable plate cell in the range, *maybe* you could resonate, but I dono, it could be tricky.

I am trying to make sure all my coils are wound exactly the same, so if there is a chance of resonance then I will be prepared for it.

What are your designs for an insulated cell? I'd like to see

My diodes are RHRG30120 1200 volt, 30 amp.... These are way over rated, $2.20 each, I bet you would do fine with less amps and less volts, but I wanted to make sure whatever comes out of this alternator I can handle.

i should have some pics tomorrow of my new coil winder.. turned out pretty sweet..  heres a pic of what im shooting for for a sinle 3 or 4 inch tube..  trying to keep it simple... might need to o rings to seat the caps and some sort of vice like mount for it to hold it closed when in operation... also the bottom inlets may need some sort of connection to feed water as dynodon said.. as for the hole size and how many it up for debate.

3 secondaries done, used a better tying method so they come off much more organized



Now I have to get some wire on a second spool so I can wire the bifilar chokes.
