Made a few Halbach Arrays today and thought I would try them with a Tri-Force Roller.

@CLaNZeR,
Great work, mate, as always. Waiting to see that crucial experiment with the rotor and this arrangement as stator. That nasty initial barrier, prior to the point you place the roller is the culprit. If this helps to overcome it that'll be it. Recall there were suggestions that Halbach array was at the basis of Steorn's contraption. Good luck.
wow! very nice! :o
COOL STUFF good luck/experimenting Chet
This may sound dumb but could you tell me how exactly The Halbach Array works? Do i just use magnetic cubes with the north and south facing different directions? do they have to forcefully be held together like they way you have it?

I placed the North pole faces the way the arrows were pointing.
It is a bit tricky holding each magnet as you put them in place as they will try and right themselves.
But a bit of wood with a 1/4 inch slot should work fine.

Hi Omni
Yep the Sticky Spot still there on the entrance, but seems a bit weaker.
Will make up a few more and try the Rotor.
Cheers
Sean.

Just had another thought about making bigger lengths as picture below.

As we know, when ever we close the loop on any magnets, including the Tri-Force Gates, they cancel the field force out as no gaps. With this setup will it do the same?
ummm
Decided to make some longer lengths first, so just ordered 80 * 1/4inch cubes and I will make a couple of long lengths that should come out at just 200mm.
It will be interesting too see if it performs as good as the Tri-Force gate on longer lengths.

Will update thread when they arrive.

Hi everyone I have been lurking about for a while (few months) reading the magnet motor posts and like what you are doing :) I thought it was time I signed up and contributed in some way
@CLaNZeR have you tried taking one array and using it in the normal trigate setup as the "roller" but limiting its movement so it doesn't roll and fixing the strong point so it is either infront or behind as it enters and leaves the gates... what I'm thinking is it may be possible to restrict the attraction as it exits and/or help with the sticky point on the next gate... or it could just create a larger sticky spot which is most likely to happen as normally happens
my magnet selection is limited to cylinder and flat neo's so its really hard for me to test this without buying some cubes :( but I guess they are the next ones to buy for my collection

Hi AKA
Good idea and have thought of trying this later.
The Halbach Array certainly has a weird setup, if I run a small magnet over it and mark the poles it comes out as the picture below.

Will let you know how it goes.

Just noticed this topic and thought I'd add what I found with the tri gate (if you hadn't found it out yet yourself). Hopefully it will help with testing and shed some further light on tri effect.
Found that stacking tri gates width wise, instead of linear, increases that thrust, so more roll away.
Just keep adding magnets till you get to the final tri gate---continue the same polarity pattern though or it won't work.
Picture attached, hope this helps and thanks for sharing your results

@CLanZer
If you maintain the polarity sequence there should be no cancellation of flux when you build it into a ring. This is true when running a Halbach ring of coils and in Nasa reports on magnetic bearings. When you close the ring the active side should show much more focus.
I've done it with sequentially aligned coils but not with PMs.

Hmmmm....
Sorry 'bout that ClaNZer.
I keep forgetting when I post a comment the thread generally goes to the bottom. I don't know why. My bath isn't due for another 27 days ;D
Good luck trying to make a motor out of it. I failed. But I couldn't afford the magnets. I just used cores from old AB 700N relays (have access to a never ending pile of switchgear parts). It was probably the gap created by the winding that did me in.
The movement in your vid reminds me of lateral 3-phase electrostatic induction motors.
Other than that - this finding of yours seems very promising! I hope to see a vid of your Halbach array rotor between two tri-force ring stators.
Will try find time to catch up on comments tomorrow.
But for now Part 2

Hi Ray
I can see your picture clearly and many thanks.
I take it the entrance end is the single gate?
Do you just have one gate each side accept on the final gate?
Cheers
Sean.

" I take it the entrance end is the single gate?

Sean, the entrance is the lower/ flat side of the triangle.
I think you misunderstood the drawing. I was was just showing the progression from a single trigate to the multiple one (which forms one big one). I included another drawing to show. One on each side of roller. Remember, continue same polarity schema or it won't work......uumm, ok, I'll do a drawing showing this (wanted to be lazy). Especially since you go through the trouble of making video demos.
Hi Sean,
nice video.
Try to incorporate some 90 degrees iron core pieces like in this video:
http://www.overunity.com/index.php/topic,4428.0.html
Then you might not get this reversable attraction effect of your ramp.
Good luck.
Ok, it's kind of rough, but here is the polarity drawing (I need one of those computer sketchpads)
Why it didn't work?
I tried to watch the videos on YouTube, but the videos are no longer available.
Just downloaded the 2 videos from overunity.org.uk and watched...
@CLaNZeR: Have you tried use just one steel ball and one Halbach array (not two paralel arrays)?
Heeeeeeeeey!!!!!! CLaNZeR, you are a genious!!!
I was watching the first video (CLaNZeRHalbachExperiments1.wmv) and I realized that you made the runner overcome the gate of the second Halbach array after exiting the first Halbach array...
It's just after the message "Now for two Halbach Array Gates". You put the runner after the gate of the first array. Okay, you used your hand to do that. But after the runner exit this first array, the runner enters the second array ALONE!
And you did it again after the message "Entrance Sticky Spot seems less than the Tri-Force Gate". Man, that's amazing!!! The second gate (entrance sticky spot) is entered ALONE by the runner!
How long that could be? If you had put a third array, the runner could overcome the gate (entrance sticky spot) of this third array? And a fourth? And a fifth?
Couldn't you had make the runner goes on for 100 meters just putting array after array? If the rolling surface was covered by piezos, how much power could you have stored after 100 meters?
Please, try that experiment again!!!!
Look at the date of GlanZers findings.
Why do you think this discussion has ended in 2008?
I gave my arguments over here: reply #2 of http://www.overunity.com/index.php?topic=9053.msg237548#new.
