So that works-out to an overall-average of 9.2% INCREASE !
Maybe the ratio of how much wire was removed to how much power was lost is not linear but I don't see it as an increase, really.
Of course the ohm value where the peak power occurred has shifted down along with the working impedance that was reduced by removing wire. But the peak is still lower no matter how you cut it and when I remove another layer it will be lower still. The headlight will be dimmer...
____ Please don't ! _ As THIS-thread is already TOO-long as well,,
Not to worry, I was only joking. If I do start up the again on the old stuff, it will be in a new thread.
____ Please let us know whatever you're turn-off to.
Sorry to endlessly re-hash this stuff but endless seems to fit right in here, lol.
On the last go around, it all became a sort of many-headed beast that couldn’t be controlled from propagating into that which whenever we found an answer to something, it just raised still more questions that then led in still new/different directions.
Not only could we not finish it, it just grew exponentially. And continues to grow, this very thread is really just an off-shoot of it.
I poured a lot of heart and soul into it, as well as much time and effort, only to see it die just as an actual conclusion of sorts was in sight. I gave it a shot on my own but there were still some pivotal questions that I couldn’t answer so it seemed pointless to continue with possibly important aspects left as inconclusive.
Believe me, I’m not thrilled about going back through my own stuff just to get up to speed enough to continue on with it. But after what I already put into it, a bit more effort to come up with something useful out of it is a no brainer.
Bob, you-yourself don’t even want to go back to it, the cumbersome entanglement that it is. You think anyone else will?
Tell me it’s not all but useless in present form, all that effort, all but wasted…
My point is…
I’m starting to feel this one going the same way, just another endless rabbit hole that, while interesting, has even less potential for some tangible benefit.
I only got involved again because of two things really, to see if this track had some substantial value on it’s own and to try to get answers I needed for concluding the old thread. As soon as it became apparent that gains to be had with the rewinds are not very significant, I started losing interest and the effort-to-result ratio is rapidly becoming less than acceptable for me…
I think it’s great that Bruce will get another go at unwinding more stock coils to clear that up once and for all. I’m all for trying a couple more winding configurations that if nothing else may at least answer questions I had about JBCollier’s rewound stator. But I don’t intend to chase this too far into the future just for some largely academic conclusions.
Some perspective on testing…
Once the coils are in place/wired up and the stator in place/lined up with the rotor, the testing part is easy. Just a matter of swapping a bunch of test leads around to get various loads, rectification or whatever. Recording dozens of test results and tabulating them to digital form is a bit of drudgery but tolerable to some extent.
When I have to change anything that requires getting back into the stator, it tends to get time consuming. Never made a puller for the stock rotor so I tap on the mounting/motor shaft end to dislodge it (it's quick, what can I say..), eventually causes alignment issues that must be addressed or the resulting various contact between stator/rotor can skew the test results. You have to understand that I’ve had it off hundreds of times by now. Never thought the fixture was going to be more than a temporary thing so didn’t put much time into making it particularly robust.
Also the coil bobbins are brittle/delicate, fit tightly on the stator and it’s difficult not to cause damage when pulling them off. And two small coils have to move to remove a large one so lots of that is wise to avoid.
Same goes for the wires entering/exiting the stock coils that have been reconfigured uncountable times by now. It’s only a matter of time before one parts company in a blind location, if it’s an inner winding then it’s all over for that coil short of a rewind.
So when I need to add/route/colorcode 8 more wires to test independently the output of both inner and outer windings on both large and small coils, I have to ask how important it is…
I still have plans for that stator if I ever get back to things like a DIY for the ‘3section mod’, if it survives the abuse long enough…
And when the data isn’t what was expected and test methods come into question, chasing down possible problems that are a complete unknown is a big PITA.
Having to go through everything front to back, end to end, point to point and then repeat testing to see if anything changed takes longer than anything and often only confirms the original result.
Then there's the relentlessness of banging out these responses…
