Major kewl since this is the 50th anniversary of the Lego Brick

may they lead us out of the valley of the evil oil barons!

LOL  -  Thanks Terry, I enjoyed your biblical take.

Perhaps they'll sell bricks you can build into commandment tablets 

Sorry - I digress

Hi Omni,

I had looked up the weight of Al's stators some time ago, and they were 10g.  So yours are fine.

I suggest two things.  First, is using identical damper material as Al.  6061-T6 Aluminum Alloy.  I paid $5.00 for a 12" piece and I am waiting for it.  (and my correct sized rotor)  Any other metal, including pure aluminum will not be the same.  It will change the braking, etc. 

Secondly, testing with different strength rotor magnets.  We want a 30.5 mm separation if possible.

Oh, and lastly, measure from the outside of your stator, to the outside edge of your rotor.  Al mentioned it needs to be exactly 5 mm.  4 and 6 mm will not work.  It must be precise.  (Al's statement)

@ Bill
I would strongly suggest ordering the 6061-T6 Aluminum Alloy for your replication.  It will make a difference IMHO.   

Cheers,

Bruce

@ Bruce
Yep, been there, have that and been testing that.

& all
Ok I have been reluctant to state this, but I am NOT in agreement with Jason's Drawings as you know from previous posting of mine. I find it peculiar that the original spec was changed to what Jason work up due to the way it appeared to him during his drawing creation. I understand that Al reviewed and approved his workup. Q why was the original spec changed ? So, that being said i am working a rotor that is to the original spec.
In addition the Dampeners were a add on to control what Al felt to be an overspeed. I do not deny that they seem to contribute to the spin down cycle and will be in place for testing when and if I get motorization. There are Pic's of the device supposedly operating without the Dampers. What i am looking for at present is the pre-operation of the device before the secondary stators are stopped. I see it as a positive cogging effect for lack of a better word.
I am in agreement with the mass of the various components i.e. Rotor, Stators, etc. for a recreation of the device although due to the vagueness of the creator a more accurate spec could and have been posted.

@ Jason
Please do not take my statement as a negative toward u and your drawing workups, As i have stated before u have done a excellent job with the interpretation and my own interpretation could be incorrect also.

@ Omini
Relating to the two holes in the base plate, Yes it could be as u stated, but i am uneasy with it due to statements that OC made. Last night i worked with secondary magnets under the base during spin down tests with AWG and found that by placing the secondary magnets in location representative the two holes i did find a change to the stator behavior. This tells me that a these holes are there for a purpose or at least it seems so at this point.

Best Regards
Bill

@ all,

hmm, electro magnets? i guess it will be seen.

@All,

My N38 neos came and the NN and SS separation is again 31mm to 31.5mm (@alsetalokin's is 30.5mm, he says). Will have more detailed data (kgauss) in several days which I'll post as I did with the data I already took of my current N42 magnets.

The most urgent problem at this moment is to find a way to decrease the weight of the rotor from 303g down to 258g as it is in the original.
