@ Bill,

Please repost your pictures, as I have not yet seen them.  Learn to ignore the rants of others, Bill.

@ Cub
If you want a spreadsheed, etc.. I say if you have the burden, go for it.  Rantings do not assist the effort. 

@ All
Bill contributed greatly, proving that the rotor weight does indeed matter greatly.  This is important, to get our rotor weights to the exact weight given by Al.

Does anyone know how Sean's testing is going?

(Our correct sized rotor should be finished Friday and in the mail.  You have no idea how frustrating it has been.  My 6061-T6 alloy arrived yesterday.  I will have it cut and drilled today.)

Cheers,

Bruce

EDIT:
I just weighed my rotor that is 3/8" short of Jason's blue print.  Weight:  258 grams.   

Please explain more. How do you mean "3/8" short of Jason's blue print"? Is it the thickness or the diameter and is it with or without the magnets?

Just out of curiosity, I decided to see if I could get stator agw lock to the ring magnets in my newman motor, see image
(http://cosmopod.com/mysite/barefm/op/agwmotor.jpg)

The image represents looking down on the setup from above, the red bar is the motor spindle, the green is the coil, the black is the ring magnets and the grey is the stator lying on its side.

Sure enough I have got agw lock and it is still spinning merrily away as I type this, of course the newman motor is powered  :wink:

The rotor is also spinning merrily away in the same plane as the newman motor on the left hand side of the setup.

Just posted for a little experimental fun, btw the agw stator spin has been going for 3 hours now.

Gotta do something while waiting for Alsetalokin to make an appearance (http://www.overunity.com/Smileys/default/tongue.gif)

That's neat. Does the Newman motor draw less current after agw lock?

No, approx 30ma without the stator in position and 40ma with stator, and it does not matter if its agw or gw.

Hi Group
Ok, after thirty years of working in the Engineering field I finally retired. I put up with all kinds of crap like most working Engineers do. Now I don't have to. Arm chair Engineering is needed, as some folks do not have the resources or abilities to take an idea from the chair and develop it into a working proto type. The way i was mentored and trained was to be capable to do this. I understand why Al changed his proto from a bearing mounted rotor to a shaft mounted supported system and this is why i move toward this in the second device. I constructed my first device and saw a instability that was corrected in the second device. We really do not have a true specification to follow, because if we did i would have followed it to a tee. So that being said the evolution of my experimenting of the OC MPMM will evolve as my background and instincts guide me.
I do not want to influence anyone with there choices relating to this Sudo replication, I say Sudo due to the fact that a generalized guide has been developed, but the specifics are yet to be revealed by Al. It is my hopes that all who work this are successful and learn something. This is what life is really all about a quest for knowledge.
Enough Stated and I apologize for being a bit off topic.
I have attach the Pic's of my second device and will attempt to answer any questions relating.

Thank You
Best Regards
Bill

@vipond50,

Thanks for putting the pictures back. What is the  weight of your rotor with the magnets and the bearings? You may have said that already but I've missed it. Sorry if that's the case. I'd be willing to see also graphs of the magnetic induction as a function of rotation angle, similar to what I posted for mine, to compare notes. Good luck with the replication.

Omni,
I posted a photo of my set up and explained that the machine shop cut our rotor 3/8" shorter in diameter than it is supposed to be.  They are rebuilding the rotor to the proper dimension. 

But, if the dimensions are correct, and we are using the proper HDPE (there is only one type called HDPE as far as I can tell) why will all of our rotors be of the incorrect weight?  Something does not add up.

Either the dimensions are wrong, OR the material is wrong.  The rotor weight must be made to be exact, based on Bill's experiments.  IMHO

@ Bill
Thanks for the pictures.  You do very nice work.  I may send my rotor off to you to carve out for me!  LOL  (When it arrives, that is!    )

Cheers,

Bruce

@Bruce-TPU,

Do I understand it correctly, just the HDPE part (without the magnets and the bearings) of your rotor which is 3/8" short of Jason's blue print weighs 258g, right?

Hello Onmi
The mass of the rotor is 252.0 grams with the magnets. In this setup there are no bearing mass to measured, because they (bearings) are intergraded into the rotatable rotor support Ass.
I am currently waiting on a new Gauss meter very similar to yours and will be do a workup then.
BTW nice instrument.

Relating to your rotor and mass removal, I am going to take the rotor in the Pic's and continue to remove mass (Sacrificial rotor)to observe the effect of how this mass reduction effect the way the device is responding. There may just be a area of less mass that will bring about Joy.
I do NOT recommend for others to do this, because if I muff it up I can always machine another rotor.
