Bloch wall shifting generator

[SkyWatcher]

Hi folks, this thread is based on a simple generator principle that im sure others have already discovered, however after tests with a simple design i built it seems to work rather well and has very little cogging drag. I originally built it to test flux gate generator principles where a piece of metal or bolt in this case passes between a stationary coil-core and a stationary permanent magnet to generate voltage/current, however what I have found is that if the magnet is placed at the back or other end of coil-core the generated voltage is almost the same and the cogging drops to a very low level. So whats happening I assume is that as the bolt or iron, etc. passes the stationary coil-core with permanent magnet placed at back side of core, the neutral or bloch wall of the permanent magnets field is shifted more towards the rotor gap which emulates the expanding and collapsing magnetic field required for induction and with very low drag and no lentz drag either because only steel is rotating. If anyone else has experimented with anything similar or has any thoughts please share them, thanks. Here is a cad pic of the simple layout.

I believe i remember in your old thread that you were thinking about putting coils on the rotor as well. How is that coming?

[SkyWatcher]

Hi redeagle, thanks for reply. Not sure which thread you speak of, although in this design a coil on the rotor would probably cause lentz drag which is what I'm mainly trying to avoid. You know last night i just remembered where i saw a similar concept to this and it was at a site called 'transworld energy' i think. except he used a very thin rotating blocker or whatever the function was. I've given a little more thought to this and I'm not sure if bloch shifting is all that's happening, I will explain. When the bolt or a large mass of metal passes by the core with the pre-existing magnetic field due to permanent magnet, i think it's causing the flux density in the coil-core to lessen, thereby emulating a collapsing field which causes induction, maybe both functions are contributing to the cause of induction, I'm surprised i haven't seen anyone experimenting more with this principle.
your thoughts please.

Hi folks, just ran a few tests to be sure of the benefits of this design relative to the flux gate completion generator methods. Yes indeed the volts and amps are almost identical yet with this design the input only increases slightly when the permanent magnets are at the back of the coil-cores relative to pure freewheeling, however with the flux gate completion method where the permanent magnet is directly exposed to the rotating steel to complete the flux path to the coil-core the amps input is much much higher relative to pure freewheeling. Another thing interesting about this design is the amps are fairly linear for a wide range at low rpm's probably due to lack of counter emf voltage.
any thoughts are welcome.

i guess we never know until we try something. Just a thought but you may want to try bucking your magnets together for a comparison. Not real sure how much difference you will get though.

[SkyWatcher]

Hi redeagle, thanks for reply. Yes i did try the bucking magnets but it created no induction in the coils, must be cause it cancels that way. So it would seem my next step is to try and maximize the induction and then line it with coil-cores. What do you think of my thoughts on how it may be causing induction.

could be because the magnets were too far away to have a repulsion force against each other. but i guess it makes since because i do remember reading about putting steel between repelling magnets and they stuck to the steel anyway.

[SkyWatcher]

Hi Redeagle, well since its a generator as shown in the cad pic if I oriented the magnets to buck, each coil would see the same pole at each of the coils ends which cancels out any voltage generation, so would be of no use that way. Hope that explains what you were asking.

Closing the magnetic circuit

You might try clesing the magnetir circuit and see if it has more output then or more cogging. or both.

[SkyWatcher]

Hi vzon, if you look at the cad pic you'll see its as closed as it can get, meaning the only other thing that can be done is put a steel flux bridge on back of magnets which would be the next step if optimizing unless I'm misunderstanding what you are saying. let me know

Hello ALL,

I am new here to this forum and this thread caught my eye. What ever happened to SkyWatcher, his build, and this thread?

I think that this "interference" type generator is workable. Probably the same idea as Don Smith's Device #9.

Cheers,

Bruce

have you seen the 2SGen at J L Naudin's site? it's EXACTLY the same thing as this, but a solid state version, and only half the equation.....
2SGen, an amazing tiny Solid State Generator by JL Naudin

I say:
Put 2 magnets opposing each other, just like Don Smith shows to do, with coil around them, and then put a toroidal core in between the two. Don't do the crap job Naudin did with the geometry though, make it nice and symetric (he did a great job, I'm just giving him a hard time). Put the toroid with its open ends facing the magnets,(not on the side like Naudin) The magnetic field and the electric field will be exactly 90 degrees off between the solenoid coils around the magnets and the toroidal core.

This device seems to me to work in a manner similar to Tesla's disruptive discharge coil, with the 2 oppositely wound halves of the primary, causing 2 opposing fields.

If you look at the animation in my Avatar, it shows a similar thing... Take that little animation and cut it in half, then mirror it, so the ends pulse together rather than back and forth...and you have what's going on here

Hi folks, Hi Bruce_TPU, thanks for your interest in that project and i agree its similar to others ideas. I dis-assembled it some time ago, though i may rebuild it, since other avenues of research are not bearing much fruit. And this design did indeed have no lentz effect drag, in large scale or an optimized design should be investigated further by folks. Here is a couple pics i posted from the other forum awhile back. Thanks for renewing my interest.

Oh yes, in the pic that is 12 christmas led's in parallel lighting up while rotating shaft by hand at around 500 rpm with the 2 coils in series. I really could see this thing scaled up or multiple rotors and coils and even if it would be difficult to get overunity, it sure would make a nice human powered generator or wind or something similar and could charge batteries and not require any effort above that of bearing friction and the small magnetic drag present. Of course as said one could expose the magnets directly to the passing steel bolts and get more output, but the magnetic drag would become very large, thats why this design is so appealing to me. Any thoughts appreciated.

Thank you SkyWatcher for the pics and replies. With all respect, a couple of things different I am going to try from what you have. First, I am using larger wire diameter, 12 awg, with 42 strands within it. This will mean nearly zero resistance in each coil. The next thing I am doing different, is that I am using a very Thin piece of plastic, very light weight, 12 inch diameter as my rotor. And the third thing that I am doing, is ordering some very thin Mumetal that will be used in place of bolts. Steel has about 80,000 magnetic permeability, and Mumetal is aprox 400,000 magnetic permeability. As the flux extends between the magnets, the flux lines will be attracted to the Mumetal, and as the Mumetal moves past, it should "SNAP" the flux, producing current as the flux within the coil oscillates.

Very light weight rotor, reduces drag and power input. Higher permeablility may allow more distance or weaker magnets between opposing coils, which would further reduce drag. Keeping the magnet at the back end of the coils is certainly the way to go.

There is a Solid State possability of this, but want to test that idea first, and no, it is not the SSG.

Thank you for your time,

Bruce
