Experiments designing a BLDC Acyclical Generator
« on: January 03, 2010, 01:55:06 AM »
Hi All,
I hope I am not in the wrong place with this topic.  I am trying to build an acyclical machine and a homopolar generator is acyclical so, here we go.

I have read lots of conflicting info regarding axially rotated magnets and their fields.  Does the field rotate with the magnet or not?  If not, then designing my machine would be a piece of cake.  This was my first experiment (see attachment). There was no current produced,  I guess the field remains stationary  when the magnets rotate.  Then I wondered, would the effect of the Lorentz force cause the field to rotate.  If it did, then I could have a motionless generator or maybe a DC transformer.  So, I made a second coil and placed it along side of the original coil.  While leaving the cylindrical magnet arrays stationary, I applied a current to the original coil and tried to detect a current in the new coil which would indicate that the EMF of the first coil was causing the field to rotate. No such luck.
I now conclude that axially rotated magnets won't work. In experiment #2 I reconfigured the magnets and got a current.  Of course, it was pulsing , but it was juice :D
In the third experiment I used a helical configuration in an effort to overcome the pulsing and get constant DC.  The helixes were arranged so that N and S were spiraled in opposite directions. (See Pic) I also used four cylindrical magnet arrays and 2 coils to eliminate as much dead wire as possible.  Now both halves of the coil were in the presence of the rotating field and since two coils were used both ends of the magnet arrays were used as well. The helical design also eliminated nearly all of the cogging. This was successful.  It produced a fairly smooth DC.  As the RPM's approached 1000 the pulsing was undectectable with my analog equipment.
With experimentation and more precise construction, this may turn out to be something.  The gap between the cylinders was pretty large (7/16").  The magnets were small.  Could have used more magnets/helixes.  It is very labor intensive and expensive to build.
I would appreciate some input from some of you brainiacs.  ;D

This is different than I have ever seen indeed. From what is said, you are having a change of field from one place to the next as it goes. Depalma said that the fields in place all around us, is the flux that cuts the copper, so if the copper is stationary, the field would have to be altering due to magnet pole position change in space as compared to the stationary position of the copper(or conductor of any kind). This is why the claims that the copper needs to be the mover. I have thought of this, that maybe a couple of toroid magnets , opposite poles facing, that have alterenating levels of strength could be used to overcome the said paradox of the copper being stationary. Or even alternating magnets causing a very good AC component. Not sure yet. Just thoughts at this point

Thanks Magluvin for the comments.
To all the lurkers:
This is amazing to me.  For many years the HPG has been known to have many drawbacks. Namely, brushes, high current/low voltage, large eddy currents.  I offer a design which I believe  has the possibility to overcome all of these.  Am I delusional?  If you think so, please tell me.  I can take it. If not then you need to get on board and establish as much prior art as possible before it's to late. 
As a bonus, I also believe it may be possible that if this configuration (or any other for that matter) could be designed with a uniform field Lenz's law could be overcome. I know that is debatable.  Let's stay away from that for now. :-\

@ magluvin, just a suggestion about needing the copper or magnets to move, I believe if you orient the domains of the magnets you can rotate the field without having to rotate the magnets or coils you are using to generate.

this is just a thought but if a solid core can be energized such as a horseshoe bar and a shunt bar is placed north south and the coil about the horseshoe is watched with an oscilloscope would this be enough to trap the magnetic value at one moment in time and when opening the shunt give a pulse that would be valued against another moment in time for the magnetic field movement.
just a thought.

The theory is that magnet only distort the fields that are everywhere already.  If the copper is still and a disk magnet is spun above the copper, the field lines going through the disc are still and are not cutting the copper. but if the copper spins, then the lines are cutting the copper creating current. and finally, mount the magnet to the copper an move it as a whole and the fields cut the copper creating current.
Strange aint it?

Oh, well im not sure what is happening there.
What is the pane? Copper?  Where are the contacts?
Is this your own design?  Looks like something, but I cannot determine what is exactly happening.

I had a setup that I was just trying that used a loop like that but used a rotor with mags. The difference with both compared to a homopolar motr/gen is that the magnet poles do not make any changes throughout the cycle on a traditional hp setup. As far as I know. So from what I see, you poles are kinda pulsing when rotating so it can generate due to that if the conductor is stationary and the mags move.

The pic is halbach array.  The way the smaller magnets are aligned in the pic the field gets concentrated with both poles on the same side parallel with that plane with weak a field on the sides and back.  The idea is to rotate the smaller magnets causing the field to rotate, if you had coils wrapped around the stationary magnets the changing flux should cut the coils and generate without having to move the stationary magnets or the coils.

So how would the coils be posed? A window motor style? or lengthwise? If length then some would cancel, no?

What would be the best way to describe the failure of experiment #1?  Do we say that the field has inertia and remains stationary?  Does the field not even belong to the magnet?  I had heard magnets being described as a "room temperature gravity superconductor". Or something like that.
Will even the most minute distortion of the field in a ring magnet give the field traction when rotated axially? Such as a piece of steel mounted on the rim or a small cut in the rim or several?
I am going to do another experiment next week similar to the failed experiment #1.  Instead of using disk magnets, I will mount four arc magnets around an iron rod.  Four north poles out on one end and four south poles facing out on the other end.  Will the fact that these magnets have segments (and a certain amount of distortion) give the field enough traction to rotate with the assembly?
Sorry, I've got too many questions :D

You would just wrap the coils around the longer stationary magnets like it was a core.  I got the idea when I saw a thread a while back about a bloch wall generator, it seemed like a halbach array would be perfect for it.  I'm going to start building a motor/generator based on this soon but I plan on trying out different coil configs like series flat coils or rotated rodin eneagrams, with high permeability spacers in between.  I posted a pic in another thread (another way to fight lorenz) that might help to visualize better.
