Rotating halbach array idea.

You Rock, my friend.

Even if this never pans out you have made the effort and that is what counts. I fail 99% of the time because reality is seldom what I think it is, I am often mistaken. However success has little to do with being wrong but recognizing when it happens and changing what we do and how we think. If one cannot change then one cannot move forward and learn... the only metric or measure that counts is learning.

Thanks for your kind words :-)
You are absolutely correct. This i just for fun and learning. At least I have learned that neither 4:1 or 2:1 gear ratio will keep the halbach configuration in position. I had to twist my brain a few times, because the rotormagnets are turning the opposite way of the rotor, and that must be one full backwards turn from 12 to 6 o'clock. My third build have 3:1 gear ratio, and that ratio will turn the magnets correctly so they at any position of the rotor, are turned precicely to keep the total magnetic polarity in one direction. The printer is soon finished, so this afternoon I will finally assemble the parts.

Hello Low-Q I wish something from you,but for this at first I have to deliver "service worth" compensation !
Instead Hallbach-array ,would the Ronbach-array by Sankar Pat not be seem an improvement,by material and space ?
US2013062983 the offcial patent number in the U.S.A.

Now my please :

US5463914 as publication with mosaics/images/picture from the taiwanese inventor Li Yng Tyan ,:you as 3d print system user ,could you estimate the prototyping costs in  time/material/machine service for such an ready to use modell (in parts) for later experimenting ?

Without the motors,clearly !



With my best regard and in hope of good answer

I uploaded a video on youtube that explains the function of the rotating halbach array.
Printing the structure for 13 x 2 neo magnets. These will be the stator magnets.

+-10% or not possible cause torque calculation et cet. can happen,I do not know,but in the description is some technical/physical data to find !
Hope that this not means hours-and-hours trial for perfection but it would nice to know how much the experiment barrer vale in ? €/$¥£ ?
I do also not know where you live and from where will get the printer materials !Nylon ? Recycled polymeres ?

p.s.: really interested also later in DE202012002207 the modelling and application,Victor Arestov and Edvid Linevich
"Fine researching guys" but not well appreciated by the " mainstream establishment"

Hi,
What exactly do you need to prototype? The gear assambly looks like those found in bore/drilling machines.


It is not hard to make these, but time consuming.


I live in Norway, and and shipping cost from here to anywhere on the world is expensive.


The material I prefer is PETG or ABS. Tough plastic materials for prototyping.
I can also print PLA, but that material is not as durable, and does not like temperatures above 60°C - then the plastic decrystalize and become soft.


The cost of prototyping depends in the complexity, trial and errors.

Low-Q, an estimation about the costs from an ready to use model like seen here :



https://worldwide.espacenet.com/publicationDetails/mosaics?CC=US&NR=5463914A&KC=A&FT=D&ND=3&date=19951107&DB=EPODOC&locale=en_EP


Under 1000 Euros ? more/less for the prototype parts with ready montage gives 300W output in torque


A calculation in Gram/in cmv3  ? + time ?

"The cost of prototyping depends in the complexity, trial and errors."


Is the 2d-scan to 3d C.A.D.  today not common ?
