@CLaNZeR,

That's an excellent idea to arrange sending your rig to @alsetalokin for him to see if he can get it to work. Once it's sent back to you working you can help everybody else to set up his or hers properly constructed.

Wow did Al actually consent to that?? Awesome

Not sure. Someone proposed that and I found it a good idea. Wonder what @CLaNZeR thinks about it.

@Omnibus

Another idea I had was to turn the rotor with stators mounted
with an rpm controlled motor.
Using a stroboscope(which some capability to sync it with the rotor)
you can analyze the angle of the statormagnets vs. rotormagnets
at different rpm..... instead of static forces - you can see dynamic
effects caused by misbalance in magnetic or mechanical ways.
The shift between rotor and statormagnets @certain rpm is
an interesting parameter.

rgds.

someone just threw that out to CLaNZeR..., Neither Al nor CLaNZeR bit ... good idea but dead for now...

Yeah send it via cleanaway mail services .. just pop it in your bin he's sure to get it
Or maybe Omnibus can pretend to send it for you

Al seems OK with responding to my tests, perhaps its because I'm a builder, with photos to backup my research and not an armchair merchant that rants on endlessly about the hopelessness of OU, conduct of others or how it should be best done...Ooops, I think I just hoisted myself on my own petard.

I'm trying to figure out a way where by I can get Al to monitor the stator's dynamic rotation during a sync, because the stator has a low inertia it may not be spinning uniformly and like someone else has mentioned, it could be doing "teacup and saucer" or "waltzer" type rotation, like you see at the fairground.
One way involves the use of some electronics and somekind of optical encoder, for example the wheel encoder from a mouse, but I would need to make this up and send it to him as it would be unfair to expect him to make it himself.
May be able to do it using a scope to read the input off the IR diode.
What I would expect to see is compression and expansion of the pulse train.
Even a sound card could be used, now that would be a low tech way of capturing the data.
Also, I may redo my motor driven stator to have the ability to move in relation to the motor so the two are not fixed, a sort of lightweight spring drive.

The thing I was thinking was posting him parts to test on his rig.

Unless Al were to use a PO Box, I think the possibility of sending Al anything would be remote, as he prizes his anonymity above all else.

Hope this might be of help
I used my sound card and constructed a transducer consisting of a ferrite core and around 20 turns of copper wire, the measurement is taken approximately 1 inch from the stator while I maintained AGW lock by spinning the rotor manually.
What your seeing is 2 cycles of the stator.

Exclamations represent rotor edge.
"O" represents stator
[] represents transducer

 If you can come up with a 'low tech way' I would be really interested so I could get some useful data from my setup. Still waiting on my laser tach but it only got shipped Friday so it will be another couple of days  :'( . I do have a Radio Shaft down the street and a computer so if you can come up with something using those I think it would be very helpful to all the replicators.
