Danb some thoughts thus far on your appraisal of this flux test, and some urging that you should listen to Jerry's original premise.
"Hi Jerry - I was pondering spending time on this today... maybe still will although I think Flux has done a better job than I could here."
Flux has done an excellent job of testing the difference in rectification of equivelent electrical circuits here. The Delta/ star winding ratio's were well designed to reflect the differential for the three systems.
However, they did not reflect the Jerry premise of "bang for buck" The Flux test ran the Jerry coils at only 85% wind ratio. ie pound for pound, the Flux "delta" will be only 85% of the weight of the star coil .
Jerry has contended from the start that pound for pound is what he is getting at. Thus far no-one has successfully demomstrated this one way or the other. Jerry crippled his test by listening to outside influence which turned it into a test of something other than his contention. (116 turns for star, not 100:200 as he originally intended) little odd perhaps, but now a part of history.
"I dont see the need to build whole alternators to test this. If I do it I'll probably build one stator with 6 - or 9 coils in it. Any 3 adjacent coils could be wired up as their own 3phase section - so 3 could be in Star, 3 could be Delta, 3 Jerry rigged if we wanted to. Then Id be certain that airgaps and everything were the same and Id not have to be taking it apart/putting it back together so much"
In reality, I think that it will be problematic NOT to do the tests with multiple coils. The only person who has built a multicoil stator thus far is jerry (the 1kw model on the car test). This paralleling of like phase coils is where the difference may (/not) show up the most, holding the test to three coils only, may well paper over the systems greatest differences, and so should not be discounted as a useless part of the test until tested. (although I appreciate the difficulty level goes up dramatically).
"It would be fun to get another such test though - but I think Flux did a very intersting one here and I doubt I could do better than that. Maybe if I have the right sizes of wire here and all we'll mess with it today though - it would be fun!"
Flux did indeed do an exemplary job of doing his test. But he was not testing Jerry's theory, mostly just testing the diode configurations and efficiencies on different systems. This needed doing... but.... He has at my figuring, proven that jerryrig can hold its own at higher power, but not at lower, but that not in the efficiency figuring is the 15% less copper in the jerryrig system.
Now this does deserve more thorough examination. Does this mean you could have wound your latest stator with only 85% of the copper, and achieved the same power out (or thereabouts), and will this ratio get better or worse with multiple parallel coils (as in 9/12 machine).
Flux's test does not address that problem, which is at the heart of the jerry supposition.
Winding two in hand will help solve the similarity problem.
So I contend you could do " better than that", by testing that which jerry contended in the first place. Flux's test will be excellent first step in understanding what the results of the next actual jerryrig test mean, and I have no doubt will become the standard for referencing the differences between star/delta/jerry-rectification, but because of the 15% wire deficiency in his delta platform, does not test jerryrig, as espoused by jerry.
With the reinstatement of the extra 15% that jerryrig is missing in Flux's experiment, the lowspeed wind harvesting may improve markedly for no increase in the mass of copper currently used in star...who knows... thats why it's worth a look. The more testing done by more diverse people, the more believable the results (whatever they are) will be. and only then may we proceed to chjange our designs, or remain happy in the knowledge that no better one are currently on offer. To big to miss really.
What we do know, is that Jerry produced over 1kw at an indeterminate speed with 9 coils parallel jerryrig, and he claims the stator was bone cold... that still needs explanation. Good cooling, cold air, beats me...
