Houses here in the USA are usually only supplied with around 200Amps at 240 volts.

Wait a bit wait a bit!! I had met in the US only 110C 60Hz network. Do You really tell about USA labeling a rather "normal" 220-230-240 V instead? The 110V was all the time a most quirky abnormality of US in adittion to other even more irritating love of Imperial measure unit system. It would be wonderful if US have changed the mind and come into standards of all other places on Planet.

But if You have a 200A in the flat, I envy You with white eyes. We after some latest years economy changes, have in flat 5A and one say 12 floor multiapartment house with 200 flats there may happen in each phase so small that 130A for all those house.

For example, our largest telescope had about 300A input because several tens of tons weight must be moved, not so frequently but must sometimes. Year ago the energetics found that at bills they are not using so much current in average and issued then 25A fast fuses. The work was paralysed. They somehow demonstrated to local boss that peak current in moment of turning on is about 280A, thus the fuse was reverted back, but after a couple weeks this was found by electro company and this permission giver was fired as nontrustable, because he was not realizing the energo "austerity" politics well enough. Just idiots. Probably problem will be solved by means of smaller motors and powerful local generator on inertia-wheel. Nothing is so bad as energy-austerity.

For example, my close friend used in his private household the 25A fuses as sometimes he want to saw the firewood, or weld or do anything useful. Then electrical bill was changed for all "high current uses" so even if he spent a zero kilowatts, anyway he must pay about half of his pension for the "grid bill". So, he went to 10 Amp fuse and this bill was diminished about tenfold, but if he would allow a 5A fuse, his bill would be indeed tiny.

120/240 split phase, meaning each line is 120V relative to neutral and ground, and between the two lines is 240.

US commercial power is often three phase instead of split phase, but still with 120V lines, in which case line to line is 208V.

I believe most, if not all, of the places you're referring to have three phase power with 220-230-240 as their line to neutral voltage, not their line to line voltage. So, for example 230 line to neutral corresponds with ~400 line to line.

You have nearly 240 on any given line to neutral, but we only have 240 between a pair of lines. Make sense?

 

Quite possibly sir--but why do you need to be so puerile and nasty about it all? Eventually, the validity of any such hypothesis rests on the idea that the properties of 'theoretical electrons' under any conditions are only those of a real wave dynamic whose manipulation--ordinarily using magnets in which that dynamic is temporarily or 'permanently' distorted in a particular and characteristic way--accounts for electrical phenomena, such as AC induced in a copper medium. Those properties, most especially the basis of the oscillatory nature of that wave principle--described in QED-- require understanding at a more fundamental level than is possible using the descriptive approach of QED.

Really though, such a conception cannot ever be appreciated by habitual adherence to the same old-fashioned view of 'electrons' as little lumps of something (Hmm, now what could that be?) zipping around the place at unimaginable speeds, like fantastic sheep that must be whipped and herded about; rather than, for example, the convenient theoretical description in QED of that aspect of an entirely exclusive unitary universal wave principle whose behaviour merely conforms to such characterisation under instrumental observation. So, sure, go ahead and have another laugh if you must.

Why won't you refute or comment on my post #81? Your calling on all of this QED and other unknowns still doesn't overcome known, commonly held facts of electrical generation.

 

The purpose of this tread is to solve a particular design problem. Please refrain from arguing about peripheral issues and instead concentrate on helping the thread starter with is his problem. And now back to our regularly scheduled programming

 

RE:""I agree with Brevor. You are describing what an H-bridge does.""
The magnet switching is rather skewy thing, because (a) currents are drastically high and (b) voltages are very low. I had the similar problem with one six0turn magnet demanding 240A and 1 Volt, and in such standpoint any use of two igbt instead of one is nightmare if only one not willing to have a water-colled radiator.
Thus, in those situation I found an excellent solution by means of hip6391 plus hip6601. First is multiphase down-converter of voltage, thus I may use a 12V output from ordinary computer PS (I mean bold endian ATX) giving about 20-25 Amps. Converter uses four phases, thus my 240A are shifted in phases so that each igbt has only 60A to switch in average. Thus the need for radiators are diminished so much that every igbt heats only about N=i^2*Rdson=60^2*50mOhm=3.6*50=180W or radiator available for air-cooling under the fan.

In Your situation I believe the same circuit may be implemented, just two of such circuit, when one is off then other is on. At least this would give a twice smaller thermal flux against H-bridge, and allows to use an air-cooled radiators.

All the circuitry is well shown in the both datasheets, and certain (unipolar) implementation is well shown at danyk.cz/sniz2f_en.html.

Thank you for the idea--although having checked the site suggested, it seems way outside my range of technical knowledge (which you appreciate is virtually zero, if not as some here have suggested, negative) and possibly more complicated than is necessary in this situation; which is 2 sets of 6 EMs connected in parallel powered by a 12 V car battery supplying about 90 A. Still, it all goes into the brew, and one of these days, some sort of meaningful conclusion will be reached.

If you would read what I have written more carefully, you will find that I have at no point argued anything in contravention of commonly held facts about anything. Your attitude generally to all of this does not invite polite reply either. However, perhaps you would have more sympathy with my situation were you to appreciate that I simply 'invented' this apparatus with no thought whatever to the sorts of hypothetical conjectures about it which arrived later--none of which are of any consequence whatever unless some output from this device actually eventuates. Alright. What am I to do--just forget the whole thing because others cannot imagine the principles which might be involved? Some bloke here yesterday was overcome with self-opinionated mirth because he incorrectly supposes that the device attempts to 'use Larmor precession'.

All I have said is that, were the apparatus to produce a specific AC wave form with peculiar properties (possibly increased conductance)--and it is a wave in any conditions precisely because any form of AC effectively harnesses the inherent momentum of the constituent components of a copper medium, however these are imagined, to transmit what amounts to magnetic force in that medium--, it would be because the configuration of EM inductive relations has been able to accommodate more efficiently these intrinsic properties of energy/momentum within the copper conduit.

Now, you can call that 'scientific hand-waving' if you want, but it is beside the point; nor is it appropriate to characterise the entirety of existing knowledge about 'electromagnetism' itself even as 'simple' when no proper understanding of its fundamental basis has yet been imagined beyond its description according to quantum field theory, impeccably precise and useful as that most certainly is. Alright.

By the way, we have BS meters in Australia too, but what has been found is that they are far too sensitive for use even close to the mainland of the U.S.. A mate of mine even tried to smuggle some through the Wall in hermetically-sealed containers, but the shipment blew up at Acapulco.

That's the point: the 'old-fashioned view' embodied in the modeling technique used in that paper, and in any such computer simulation methods, is not really capable of predicting the behaviour of this generator simply by virtue of the complexity of the EM inductive relations involved.

In case you miss it, this is what I wrote to 'Short-whatever':

(If you really want a blast, look up the textbook; ''A Wave Theory of Universal Resonance'' at 'Grin Verlag'; bearing in mind that it followed by a long time the 'invention' of this apparatus).

Thanks, I needed a laugh today.

Typical copper electrons have a random thermal speed of hundred thousands of meters per second for a metal like copper with an average velocity of zero. The drift velocity of current electricity is the net velocity of electrons in a certain direction under an applied field. It's in the order of 2e-6 meters per second for a 10A current. Your hypothesis of quantum mechanical orbital angular momentum using Larmor precession seems unlikely at generator frequencies.

For the record--and if the moderator will permit a point of clarification--, although it's a while since I thought much about it, I admit that what I wrote in the 'blogspot' gives the improper impression that the principal aspect of the hypothetical effect imagined--that efficiency in EM induction might be enhanced by better accommodating the properties of electron spin--is that of Thomas precession (and no doubt I was distracted by the implication of the 'fine structure constant' in the calculation of the 'ge' factor, for which my model of a 'cohesive field' offers a clear explanation--so I think); and the point you make is quite valid that the scale of such precession frequencies is scarcely imaginable in the context of this generator--or even beyond a cyclotron/synchrotron; so I find myself grateful to you for compelling me to consider this more deeply.

Still, the geometry within which this precession is implicit--described by the 'ge' factor (and the anomalous 'electron magnetic dipole moment')--is nevertheless a peculiar property of angular momentum (described in QED theory) intrinsic to the dynamics of displacement of magnetic force (which it is convenient to consider as primarily due to the tendency for iron to revert from its state of 'polarisation' as a ferromagnet) to electrical circuits, comprised of copper in particular, and what is supposed is that the form of this generator may be capable of facilitating greater efficiency in this effect. We'll see.

 

After rereading your blogspot yet again, I'm now on your side in this. I'm sure that your wooden frame build will be able to change things at the molecular level . I totally missed what you were trying to do before.

 

We'll see.

Will we?

You're proposing a fairly complex experiment with self-designed and self-built? apparatus. Your hypothesis is that you can somehow manipulate spin to your advantage. The hypothesis contra or null hypothesis says you cannot.

If you hope to produce a result worthy of sharing with the world - ie. publishing - you'll need data good enough to reject the null hypothesis with confidence, typically 90-95% or more. Otherwise you're deluding yourself.

How do you plan to distinguish the behavior of your apparatus per both hypotheses, so that you can tell with confidence which hypothesis provides the better description of the observations? How will you measure whether your attempt to manipulate spin has actually worked? Can you turn the effect on and off without otherwise disturbing the machine, or without making room for a more conventional hypothesis?
