I call it "The Helix Screw Magnetic Motor".
First post so be gentle, I've been following closely with eyes wide open over MyLow's project and the way he has been belittled and I am disgusted with the mind process of some members here and other sites. I certainly hope you don't all scare inventors away the same way as some have done MyLow.
The red on the helix shaft is a partial magnet running along the shaft within a 1/4" groove that was machined in the shaft. It is being held in place with a red cocking. The prototype is not finished as I still need to finish running the magnets the full length of the screw.
I've got a right handed helix screw going clockwise and I've got a left handed screw running counter-clockwise.
I've attached some pictures of the prototype so you have an ideal of what I'm talking about. Have you encountered a machine that works on this principle? I understand that in order for a machine to work one must overcome the flux gate.
In theory, could this design with the incorporated helix screw shaft bypass this issue???
I'm challenging you to put your expertise against this design, I would love to know what your conclusions would be.
My limited understanding of magnetics is that you'll always be outdone by the flux gate as long as your toying with it in a 2 dimentional design. That is presicely why we choose the helical design and crossed it over to a 3 dimentional design.
What are your thoughts on this design?
I spent to much time trying to add attachments to the post, keeps telling me timed-out.
So here is a URL to the pics.

That's definitely not something you are likely to find in Grandpa's attic. I've never seen anything that resembles your device. Looks like an awful lot of work. Even if it doesn't work, you could display the finished product as a piece of techno-art.

There will be eddy current losses in the aluminum. Fast speeds will be worse than slow speeds. You might want to consider using a material which is not electrically conductive (plastic or wood).

What type of magnets and how are they oriented? Have you tried to model, or even just to sketch what the dynamic magnetic relationships would look like?

Definitely something different.

Nice one, looks cool.

Look forward too seeing more.

Cheers

I like the concept of the helix and it's always good to see someone building, experimenting, and testing. I've been thinking about a helix design for a few months now. Although, your helix design is different from the helix design I had in mind, it's good to see someone tinkering with this idea.

I believe the electrons flow in a helix (corkscrew) motion around a conductor and the electromagnetic waves also follow a corkscrew trajectory path through space. I think this corkscrew motion deserves more research, since it appears to be how nature is working.

Good luck,

@The Nephew,

It looks like an amazing bit of engineering, congratulations, but....

Maybe I missed something, can you tell me what it is supposed to do and why?

I had rectangular permanet magnets machined to fit in the grooves of the helix. The project has been sitting idle for quite some time now because of financial reasons. This machine was put on paper about 20 years ago, so it has been a long journey.
The only reason why I spilled the beans on this project so early, was because of poster carbonc_cc had spoken of a similar design in another post. So the inventor decided that it would be a good time to make it public and maybe along the way give people a different perspective, ideals...This machine is not finished, as it does not have the full length of magnets running along the shafts. I never claimed that it is OU. Once the rest of the magnets are installed, we will see...
The helix is attached to sprockets, one shaft turns clockwise the other counter-clockwise. Theory behind this invention is that once the magnets are all assembled and the first helix shaft is moved foward towards the other shaft, by way of a threaded rod. The magnetic field will force the shafts to repel from eachother. But being stationary, they will simply rotate in a continious manner. Hoping, I've conquered the notorious flux gate.
What are your thoughts?
I only have a cheap webcam, I surpose I could put up a short video on YT?

While the apparatus is in fact a double helix,
the magnetic field is nothing more than a wobble.

The key to this possibly working are the counter rotating shafts and the little to no change in the magnetic field. It is this little to no change in the magnetic field along with the counter rotating shafts that could make this a possible self-runner.

If the magnetic field did change, then the counter rotating shafts would oppose each other and not rotate. If the rotating shafts rotated in the same direction with a changing magnetic field, then you would have a sticky spot that would oppose the rotation. No change in the magnetic field means no counter emf, which means no sticky spot.

1) No change in magnetic field with counter rotating shafts = Rotation due to the magnetic field and counter rotating shafts repelling or chasing each other with no sticky spot and no opposition force between the shafts.

2) A changing magnetic field with counter rotating shafts = No rotation due to the counter rotating shafts opposing each other.

3) No change in magnetic field with the shafts rotating in same direction = No rotation due to equilibrium.

4) A changing magnetic field with the shafts rotating in same direction = No rotation due to the sticky spot.

I am impressed with this design. I personally don't see why this won't work, but I am wrong most of the time.

A quick video will allow us to see if the magnetic field is changing or not, and if this change or no change, would oppose the counter rotating shafts. I believe the magnetic field is changing in regards to the counter rotating shafts, but the field is not changing from our frame of reference.

I think you have eliminated the problem with getting past the flux gate, but the question is, does this create or cause another issue?

You might have a better idea by looking at my video, the way the helix rotates the magnets are always synchronized to one another. Sorry bout the bad video, the LCD view on my camera is smashed out.

@The Nephew : see my PM.

Very impressive build. Bringing this one to the top.

Have you played/tested with the magnet orentation (for theory) before building this impressive/costly machine?
