Life got busy on me the last couple days...
____ Don't be concerned about it Bill, (it's not like this is your work-job), if you only achieved one step per week, we'd be jerks to not appreciate each step you manage to get accomplished !
" I've been still pondering on how to proceed with the testing and organization of such, "
____ Within THIS thread, it ought not matter too much Bill, as everything can get straightened-out in the dedicated thread for your test-work. - (Which I hope you've noticed!)
__ I think a logical progression would be to start-out with obtaining the power-output results of the stock-type set-up - (which is connecting-up the parallel-pair -[consisting of alt.winding & diode, (x2)], and measuring their combined [half-waves] output). _ (As depicted in the related diagram-scheme I've provided.)
Then next test-step (with all following done in 'half-wave rectification'), each alt.winding alone,, then next, with both windings in (standard/original)- 'series',, then next, with both in (reversed)- 'series'.
" If I'm going to put in all this effort, I don't want to compromise and confuse it by skipping a few details. "
____ Good attitude Bill ! _ I will try to make sure you don't skip-over any steps that would otherwise put things in an out of order sequence, (and hopefully others will point-out anything else I've so omitted). _ (I now see that Bruce has already introduced the final test, expected in the rectification-sequence.)
" I believe we need some work on terms and nomenclature, an example as in Bob's concern with my inconsistent use/understanding of the terms 'cores', 'coils', 'windings', etc. "
____ I sure wasn't concerned with your picked wording specifically Bill ! ...
Someone such as myself understands what you & Mike must really mean to say, but those who're just learning can get completely confused when we don't all use our terms exactly the same way EVERY time ! _ (And it's this consideration that's behind my own word-extension efforts.) _ Without such consideration, it's always an added puzzle to figure if another's wording has been hastily-picked OR purposely-chosen ! _ And when ya have to guess at that, it's likely a sure road to misinterpretation.
So I say, that if ya really wish to be properly understood, then proof-read what ya've written and correct/replace any hastily picked words.
" and the concern with 'counter electromotive force'. "
____ It's been my understanding that when electricity produces magnetic-flux, or when magnetic-flux creates electricity, (for motors & generators, etc), that's to do with 'Electo-Motive Force' -('EMF'),, and when a single-core creates magnetic-flux in opposite directions -(both N & S) at the same time, then I think it's fair to indicate: "Counter", with the results of course tending to be a cancellation-effect.
" For the sake of standardization, I have yet again switched wires around on the test setup, realizing that the original stator output wires should be the yellow/orange and not the opposite 'tag ends' (that are now purple/grey). "
____ That's good ! _ Cuz when I first read what you had had them colored as, I thought either I may not have understood correctly, or you didn't type what you really had meant, and if you did indeed mean it that way, I thought that that's going to make things confusing. _ So I'm glad you got the idea to put it more logically, on your-own !
__ So do you now have it so one alt.winding has a yellow-wire and a purple-wire, while the other has an orange-wire and a gray-wire ?
" The load resistors are all 3ohm 55w, the bottom one is in series with the other three that are all in parallel. "
____ According to this wording, you have four 3-ohm resistors arranged for a total of 4-ohms, (since three of them in 'parallel', equate to 1-ohm total). _ And that 1-ohm in series with the 4th 3-ohm resistor, makes the total of 4-ohms !
So is that correct, Bill ?
" I would also like to have one of you do a revision of the 'stator, load and rec.block' version of Mikes drawing (that most details of requests for testing would/should be based upon); "
____ Yes sir, I'll try to have such presented below (near bottom of this post).
" Add a +/- to the rec.block, add the wire color scheme to the outputs along with the 1-4, update the load spec. and somehow add the current, vac and vdc meters so they can be easily moved around. "
____ Don't know if I can manage all that (yet). _ However, for the half-wave rectification testing, diode polarity is irrelevant.
" I could do it but I haven't had time to figure out the complicated photoshop I have and it's a time consuming pain to use while 'winging it'. "
____ Don't worry about it Bill, you're spending enough time & carrying enough of the-load as it is !
" Ideally I'd like each of you to generate a version of the drawing that shows the wanted/intended setup, then I can post a pic of the test results and summary of the data to go along with it. "
____ That would indeed be the ultimate way to present each test outcome, most orderly !
" This is from Bob's post and is ok except needs the aforementioned revisions and it and the written description still left me figuring out where to put the vac meter. "
____ The AC.volt-meter always goes across the AC.power-source output-connections.
"So this should be the drawing implemented, except the current and vac meters are not in the drawing. "
____ The current-meter IS in the drawing... It's represented by the circle with the 'A' shown inside, as the A stands for Amps !
And the amp-reading remains the same, regardless of where it's connected (between ANY two components) !
'
" Half wave rectification', 3 ohm load, 3450 rpm, 2.2a, 25.2vac, 8.8vdc "
____ That then indicates a wattage-output of near 28w-AC & near 19.5w-DC.
" I'm not sure whether to start a new post or just edit them into the the existing one. "
____ If you have any 'corrections', then 'edit' them-in, and make note of it,, otherwise start separate posts (so that any single post doesn't get too large).
" I would like some direction/preferences as to the sequential order which the data sets (pictures) should be placed, or maybe I should just put them up however and the rearrange them as requested. "
____ Well in THIS thread, it seems they're already going up in random-order, so the final-presentation-order can be straightened-out within the dedicated-thread.
Fun-Cheers,
-Bob
, we who play with motors all know the type of sound. At first I though it was the alternator but thankfully it turned out to be the driven motor, it has ceased to function. Guess it didn't appreciate life in the fast lane, no surprise really, it's what happens when you push things well past what they're designed to do. It was a mickey mouse setup anyway, was kind of a nice motor though, 'borrowed ' it from my jointer.
