TD replications

After you took your force readings did you use Mr. Hand to move the Torque arm back to the starting position?

Did you try doing that while the system was in the disengaged position?

If so,, how much did Mr. Hand do to move the arm?

See,, no changes are needed you only need to have the Torque arm start in the end position after it rotated, move the other arm into the disengaged position and then use your scale to move the Torque arm back to where it needs to be so you could measure the engage force again.

Okay webby1,

to please you I added the output arm reset (return) measurement data to test 4

Seems to still have an overage

Hello everybody ,

This device remind me something you probably knows ...
http://jnaudin.free.fr/html/2magpup.htm

It was in 1998 ...

Keep the good work Gotoluc !

Hi SG

thanks for your post.

Yes, I would think the effects are similar or related.
Please keep in mind this topic is for discussion of replications of floor's device.
floor's original topic would be the place to post this kind of information and general discussion of the 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/

Kind regards

Luc

Thanks Luc,

Rounded numbers

Yes, that's because the scale works in 5 gram increments.
Not ideal for fine measurements but gives a general idea.
We'll get down to finer measurements in the next build if needed.

I wonder if the cam effect on the slide is masking the real data.
Wouldn't it be better to collect the data from the exact movement of the magnets over the entire rotation and slide distance and then determine where the best gain occures?
The cam introduces a non linear input measurement against a linear output measurement. This is problemmatic when measuring the already non linear magnetic field.

IIRC I found that when disengaging happens,, that there is an advantage to stepping that while the RO (?) is still turning.As you are pulling the magnet away you can set it up so that you expend a constant force to do so,, and while you are expending more energy the RO will continue to speed up due to it still seeing a torque.  You have that window around the 80-90-80 where the removal cost is comparatively low so it is easy to set the rate of change up.

Good idea!... I'll keep it in mind for the new build

This has just been covered some posts back: http://overunity.com/16987/td-replications/msg496936/#msg496936

"the crankshaft will influence the linear scale readings of the SL input torque arm. However, since measurements are done in each directions (engage & disengage) there cannot be an advantage or gain from using a crankshaft mechanism since if it did we would of solved the energy problems some time back."

This was (in the most part) a device already built and used for something else. I modified it to do what it does. The crankshaft was already there, which I decided to use to engage and disengage the sliding magnet and added a torque arm to it.
It's good enough as a preliminary test bed.
In my next test device build (which the output will able to rotate) I won't be using a crankshaft for this action.
