Hi Omni,

Can you please post a picture of your rig ?

Cheers,

Dean

@dean_mcgowan,

Actually there are two rigs made exactly according to the specifications except for the rotor magnets in the second rig which are the recommended rectangular magnets but not the cylindrical magnets as in @alsetalokin's video. Will post it later when I have some quantitative results.

@DA,

We're trying to be as true to the original as possible. Modifications later. Where did  you see that the stator is at an angle with respect to the rotor?

Where did you see that the stator is NOT at an angle?

[CLaNZeR]

Theory: 

Al's device "worked" because his stator was accidentally mounted at a slight angle.  Optimizing this angle will produce more power than you know what to do with.  When you build your computer controled machine to vary the distance and height of the stator, be sure to include rotation in two axis as well.  Working with the stator axle always straight up and down limits you to one dimension, when you should be thinking in at least three.  Placing the stator at an angle to the rotor changes everything.  This is why you see some replications work and others fail.  While everyone is trying to be "exact" and keeping the rotor and stator parallel, the only ones that come close to working are the ones with the stator "a little bit off".  Make it a little bit more "off" and see what happens.

Tried the wobbly effect and could not even get a AGW sync.

I messed up a few rotors as the Drill Stand was not secure and the Top hole to bottom hole over a 20mm Distance was 1.5mm out which made hell of a wobbly Rotor

@DA,

Now, that's really a metaphysical exchange. That rotor and stator are parallel is assumed, otherwise it would've been emphasized prominently. It hasn't been. I'd be amazed if anyone but you would insist they are not parallel. On the other hand, you may be right--remember @xpenzif's stator magnets also weren't parallel to the rotor.

[Yadaraf]

Testing by varying the height and distance of the stator is essential, of course.

Apparantly no one has yet considered changing the angle of the stator axle.  Having all the magnets spinning in the same plane almost guarantees no power gain.  This one dimensional approach has consistently failed.

I'm playing with computer-based automation of stator tuning, but only in X and Z.

     Q:  Relative to the rotor, should the stator be angled radially, tangentially or both?

     Q:  Also, at what point in Al's video does the stator appear angled?


Cheers.

Yada ...

Today after reconfiguration of the Stator magnets to a dual bearings I had a approximately. "one minute" self operation of the device and maintained a constant RPM once Stator Sync occurred. Note: What I mean by " Self Operation' is NO outside added input to the device. I added the second bearing to the stator due to instability to each arrangement. The instability induced friction and consequently drug down the rotor speed. Also with the device i am able at any time during spin up to latch any of the three Stators at any given time. In addition this allows me to have any combination of the stators running in synchronization.
My next step is to spend the necessary funds to Source totally all Non magnetic parts i.e. Bearings, Fasteners, Rotor center support shaft, etc. to construct a higher quality device.
I also understand that this is a variant of the original concept, but basic Engineering dictates that this is the next step.

Happy testing and may Your Rotors Rev up

I think there are 3 clear optimization steps:

1) Finetune the position of the rotor magnets
(I don?t think that all this magnets have exactly the same strength)
or match the magnets out of a bigger batch with a
magnetometer - or use a reference stator with a newtonmeter
attached.
This first goal is to get a symmetrical, smooth rotorfield.

2) Finetune the position of the stator magnets
I think that the stator magnets have slightly different strength.
If you finetune the distance of each statormagnet to
the already adjusted rotor using newtonmeter or measure the
resulting field - you can compensate differents in stator magnets
and achieve symmetrical statorfields.

3) would be to balance rotor and stators in the conventional way.

Even slightly unsymmetry and slightly different strength in the used
material can have a huge difference in the resulting force.
Measuring the force and the field is the key to operation -
then it would make sense to alter the tilt/distance/force of the stator
magnets.

Well seeing as this huge drama has gone to the garbage, it needed a supporting big budget trailer. So I made this: http://www.youtube.com/watch?v=FOEfkESHb0w

 

Brilliant.
Anyone written a synopsis on the story line yet?
and who wrote the screenplay?
I give it 5 kernels of popcorn.

... I added the second bearing to the stator due to instability to each arrangement....

Bill

hey Bill,

Any chance of a photo of the new stator bearing arrangemenet?

@vipond50,

What is the wind down time of the rotor in absence of stator magnets and does the wind down time remain the same when the stators are present and the one-minute constant rpm effect is seen?

Nice work Bill!!! sustained rotation is a big step!!

These are good suggestions. They apply to every magnetic motor contraption studied and, as it was mentioned many times, the discrepancies in the magnetic fields of ostensibly matching in shape magnets is plaguing the field immensely. The hope for this particular contraption (@alsetalokin's) was that these discrepancies will play a lesser role which obviously isn't entirely so.
