The Halbach Array Meets the Tri-Force Roller.

[CLaNZeR]

@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

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

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

@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 

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.
