TD replications
« on: November 18, 2016, 05:14:23 PM »
This topic is being created for presentations of replications of
the "TD" and similar measurement sets.

It's not intended for discussion of theory of, or the explinations of, per say.

Hello floor and everyone


The below video is a replication (a la gotoluc) of your Permanent Magnet Twist Drive (torque amplifier)
Also included below is a pic of the videos test data which seems to support (on my test device) a 37% Torque Gain on the output side compared to the torque needed on the input side.


You may want to make some popcorn as the video is kind of long (18 min) since I took the time to first explain the basic effect for newcomers and youtubers to understand how the basic effect works.


Link to video demo:  https://www.youtube.com/watch?v=bmCQVg9qRmQ


Kind regards


Luc

Hi Luc,

Great setup and thanks for taking the arduous job of building and showing it.
Of course, we need to thank first to Floor to openly share his own work on the idea.

  I agree - great set-up and data-taking. Thank you, Luc.


 It is indeed curious.


  Is it possible to convert the action here to a continuous motion?  I suppose it would involve oscillating (engage-disengage) as well as rotary (torque) motions ... 


   A small test device that would keep moving, would be an awesome Christmas present to the world!

Thanks Gyula

That's correct!... the credit goes to floor, it is his hard work that I basically copied (at the end) and shared my results to further confirm his findings.

Hopefully now this will encourage the great minds to suggest mechanisms which could capitalize on this effect to turn this into continuous rotation.

To everyone


Please keep in mind that this topic was created by floor for replicators and people who would like to have a discussion about a replicated device.
With that said, here would not be the place to discuss your general opinions or obtain information about the magnet Twist Drive effect.


Here is floor's original topic "Work from 2 magnets > 19%" which should be used for general discussions:
http://overunity.com/14311/work-from-2-magnets-19-output-2/


and another topic called "Magnets, motion and measurement" was created for beginners to discuss basic physics:
http://overunity.com/16954/magnets-motion-and-measurement/


Thanks for your cooperation


Kind regards


Luc

this 90% rotation effect reminds me of http://www.kundelmagnetics.com/
force and reciprocation.

Looks to me like the same principle. Guess they never compared the two forces?


Hi Luc,

I will watch the video again but I do not see the included cost of resetting the torque arm.


Both engaging and disengaging (resetting) are there in my video and also posted above.


Below is an input Torque chart I just now made.

Here is test 2 demo which has a higher torque output of now 3 ft/lb by reducing the magnet air gap, however, interestingly enough the overall efficiency is the same as test 1

What is the actual degrees of rotation and the actual arm lengths,, just if I want to have the particulars close,

The input arm has 80 degrees of travel and output is has 40 degrees. Both arms are exactly 12 inches from center of axle to where the scale attaches

With the system in the disengaged condition,, how much are you putting in to reset the output arm?

If I was to use the gained torque from the output to reset the output arm back up but keep in mind this is not what the test device was designed to do, as the device sits now, it would takes an average of 0.4 foot pounds from the 0.44 foot pounds left over.
This amount could easily be reduced in less than half with no extra from the input or even possibly eliminated with a design to do such a thing.
I'm sure there are better ways to go about it then bringing the output arm back up. This is what the Sunny Miller device is attempting to do. Keep it circulating.

The weight of the arms does not matter since the in and out relative to the source of force,, gravity,, is exactly the same they cancel, but you still have a field interaction that will be influencing the disc rotating.

I agree and I think it has been addressed in the test 2 video


ETA:
Just as a ball park guesstimate I think you will find an average of around .917 above the weight of the arm to reset,,
I will double check that


Not far for a guesstimate

Thanks Luc
               and others
             
The topic  Magnets, motion and measurement
was created for beginners like me to discuss basic physics.

I would like the  Work from 2 magnets > 19% output 2  to be for general
discussion of the TD principle.  All of my presentations, documents, and
so on can be found there

and the present topic TD replications    for TD replications presentations.

                         but what ever

                              best wishes
                                       floor

"Hopefully now this will encourage the great minds to suggest mechanisms which could capitalize on this effect to turn this into continuous rotation."  End Quote

If it's O.U... it doesn't need to be turned into continous rotation.
Recipricating motion is just fine.  However, momentum could be partially conserved
by convertion to ratational after the recipricating.  Think about it, I mean doing so
wouldn't exactly be wasteful, would it ?

                                     thanks again

Not sure what you mean on that last one,, do you mean that I was not to far off?


Yes

Hi floor,
I've edited my post to hopefully reflect your instructions: http://overunity.com/16987/td-replications/msg496651/#msg496651


If it's O.U... it doesn't need to be turned into continous rotation. Recipricating motion is just fine.  However, momentum could be partially conservedby convertion to ratational after the recipricating.  Think about it, I mean doing sowouldn't exactly be wasteful, would it ?


I agree and maybe reciprocal would be the first device to build but I think a rotational device would be a more practical and adaptable device.

Regards


Luc

Dear webby1

I consider your input constructive and not intrusive.

Can you post a video, pics or drawing of your device. It would help to visualize your explanation

Thanks

Luc
