So now we've had three replicators (Vibrator on Steorn, RB on Steorn, and CLaNZer here) report they are seeing the AGW lock effect. (But don't have acceleration yet - mainly due to waiting on the right type of magnets) I think it would be worthwhile for you guys to look at what AL was saying a couple of weeks ago when he first discovered the lock. It's on pages 5,6 & 7 of this thread in the Steorn forum.

http://www.steorn.com/forum/comments.php?DiscussionID=59687&page=5

He talks about the need for the dampners, and adjustments he needed to make. With a couple of slight variations in some of the replications you may need to go through a similar type of process to get the same effect as him.

Good Luck

I only lack 1/2" aluminum round for the dampers and must find that online.  No store in my city has that size (of course  :( ) 3/8" and 1/4" but no 1/2".

I happen to have a couple feet.  How much do you need?  PM me the particulars.

I think I purchased a three foot rod at The Home Depot last year at this time for my Maggie Motor.  Alas, she broke my heart so long ago.  One of you blokes better make an honest woman out of her.  Don't forget to share the honeymoon photos.  ;)

Shoot.  Timed out.  Now I have to type it all again.

I want to suggest a test for you non-armchair experimenters.  In this test you would attach a belt from the test motor to an alternator instead of using the Judson dampers.  The alternator's field coil should be limited via a linear potentiometer such that if the potentiometer was turned completely off - the alternator would have nothing to work against - therefore allowing the alternator to spin freely with almost no drag.

There would be a volt meter attached, in series, between the potentiometer and the alternator, showing how much juice was being sent to the alternators coil.

There would also be a volt meter attached to the output of the alternator, showing how much juice was being produced by it.

There would be something to dynamically gauge the current rpm of the rotor.

The Whipmag motor would be started while the potentiometer was preventing any juice from getting to the alternator's field coil - so it would just be spinning freely.  Once the third stator 'caught', the pot would be turned up just until acceleration stabilized.  When the other two stators were stopped and as acceleration commenced again, the pot would be adjusted until the rotor speed stabilized.

Testing would involve adjusting the potentiometer, to cause the rotor to spin at different rpm, in stages.  At each - the current volts both being consumed and generated by the alternator would be recorded along with the rotor speed.  This would continue between the upper and lower limits of the effect and graphed - hopefully showing a sweetspot, in rpm, where the most power is produced.

Are you thinking of the Judson dampers as a drag on the rotor like a belt drive?

I could be wrong but I think the dampers function is to help the stator's inertia to carry it through a sticky spot when the rotor reaches a critical point, to help accelerate the rotor and stator(s), not drag the rotor down like a belt would.

A belt or some other PTO will need to be added later, but this baby is still in the delivery room with momma and it is too early to break-out the cigars.  ;)

@ Rosphere

Thank you for the offer.  I sent you a pm with the details!   ;D  I don't need much.  LOL

Maggie broke your heart, but perhaps the OCAL will put it back together again.

Thanks as always,

Bruce

@Clanzer

you wouldn't happen to have a slow-motion camera?
or access to camera with a fast shutter speed to see the alignment when the syncing happens?

Hi-speed cameras generally cost quite a bit of cash. There are some types of camcorders that you can force to go into 60fps as opposed to 29.97/30, but this feature isn't generally supported in typical household cameras by sony or the like...

But you never know... perhaps Clanzer does have one  ;)

Sorry Rosphere too lazy to find the link, but somewhere in the development thread over at Steorn (I think about page 5 or 6) Al discusses the need for the Judson Dampers. Prior to using these, the device once "in sync" the stator would accelerate up to over 8000 rpm's, become unstable and drop out of sync. The dampers provide drag on the stator, to slow the acceleration and stator speed. They don't help accelerate the rotor and stator, they do the opposite and keep it "balanced" and in sync. This is what I find most interesting. Other ways can be found to provide that drag/control mechanism that can generate usable work.

@All

I am still not clear on whether the JDO specifications are exactly what Al has built or not ?
Can anyone clarify this, it seems a grey area, or did i miss a post regarding this?

Dean

Hi Dean,

I just asked about Al Confirming my blueprints yesterday. Here's the posted response about it:

http://www.overunity.com/index.php/topic,3871.msg69936.html#msg69936

There was only one minor discrepancy with the Rotor's shaft not being a bolt, but Al mentioned on the Steorn forum that he was using a screw axle when he originally got it working.

God Bless,
Jason O

Well spinning the Stator magnet using Air certainly will stop me taking skin off my fingers!!!

Heres some latching with 1 Stator Fixed again, 1 Stator loose and of course the latcher!.
Also in the same video latching with just 1 Stator, again using the airline.

And yep it does sound to initially speed up when it latches as you can hear.
I will get the Tacho connected back up and see if we can catch it.

Got to go try eat this end, as had nothing all day LOL  ;D ;D ;D

P.S Sorry the videos are so big but I want to try and keep them atleast 640 * 480 resolution, so you can see what is actually happening.


Way to go!

I initially thought I heard the rotor accelerating in your earlier video but it is VERY refreshing to see a second person get this thing going! Keep up the great work! Soon I'll be in on all the fun as well  ;)

I also bought a decent Tachometer from eBay so that I can take RPM measurements once I get my rig up and running.

Hi Jason,

very nice job on the drawings!

In my opinion Sean's version seems both more stable and flexible adjustment wise... which could be very important when it comes to fine tweaking...

I think that most of the difference is in the base plate... do you have any plans of doing a drawing based on Sean's model??

Thanks

Geordan

Hi geodan,

I absolutely plan to build an adjustable model for further testing. I'm only sticking to the original model strictly for replication and validation reasons. The next version I make will be much more flexible to experiment with and optimize the design.

God Bless,
Jason O

Exactly, JAG - I read the same thing.  All suspicions are suspect at this point ;D but I suspect that the reason that Al's motor quits above 8,000 rpm on the stators is that the stator bearings can't keep up with the rotor and the motor falls out of 'gear' phase.

geodan, Jdo
I'm pretty sure Sean's model originated with CAD files of some sort as he uses his CNC machine to crank the pieces out. In that sense the drawings already exist.
Here's the base:

I agree. Another thought (helped by someone at Steorn forum) is that the Dampners are magnetic "sinks" which could result in a change of temperature. As we know even a slight change in temperature can be used to create usable work via a Sterling.

I'd be interested to see one of the replicators do a temperature test comparison of the Dampers pre and post run.
