Figuera Device, Part G Continuum.( Serious Builders Only)

Cornboy, I noticed that your carbon piece protrudes quite a bit and at higher speed may be causing the vibration in the carbon. If you look at the brush on my commutator that ufopolitics posted on this post earlier, the carbon brush is almost completely covered by the holder. I have have good success with this design even at very high rpm.

Thanks Grey Wolf, all that will be sorted on new holder.

Thanks guys, i ran it for quite a while and bedded the carbon in before i ran test. i pulled it down to check the brush for seating, and was fine.

It is a basic design problem, that sets up a vibration wobble,causing the brush to skip, if i was commutating on top, this wouldn't be an issue.

The brush holder just needs a double bearing support.

BTW, the centrifugal force on the brush at full speed is no problem at all.

Part G

I agree.

Corn boy, you may just need to run the brush for awhile so that it seats in and makes better contact. The commutator company from Tennessee that I have been in contact with called ACT have commutators that have been "run in". I would try that first rather than rebuilding from scratch. Grey Wolf

Hello All, i did a rough preliminary test with my G and 2 x 12V bulbs, per the previous test.

Unfortunately I had big negative spikes,and fuzzy main signal, which i think are caused by brush contact problems.

The brush setup is not good enough for the accuracy needed for internal commutation, so i will rebuild my brush setup with larger bearings on both sides of the plug, with a one piece spindle through the bearings.

The overall form of the signal of both channels was in sinc, not opposed, but need to do a lot more testing to confirm that.

It may take a while to do, as i need bearings and aluminum billet to make new improved brush holder.

Part G

Looks very good cornboy, love how the brush turned out and wide enough to span two windings at a time.
sure wish i had a lathe, life would be much less complicated.

Hello all, Brush Holder ready to Go almost, just have to assemble and balance.

Part G

Indeed lots of work going from a vertical brush to a horizontal brush and in a tight space but we have faith in you as your building skills are up for the challenge.
variacs use regular magnet wire so i see no reason that it will not be ok aside from the fact you said you have a light weight brush for the job. also Doug used it in the same fashion and worked very well.

"Also i can split the winding and make a brush wide enough to cover the split, so it makes before breaks"

Yes Excellent , and it should be so as the distribution of the kickback is crucial as it will be evenly distributed in both ways throughout the core.and that is what i planned all along to have the brush wide enough to cover two winding's at a time having two carry the weight instead of one for less wear also.

I'm sure you can have the grove across the bottom of the aluminum plug just the same as the one you have now.

Your progress is still faster then mine as i am waiting on income tax to get here and to start a house remodel. i think humanity will be ok until the device is running besides the fact that it is MONSANTO we have to worry about not our neighbors. The dealer of death

Finished machining my Commutator, ahhh, Part G, ahhh, Garden ornament.

Only had to remove around 15 thou to clean up, which i was pleased with.

Man what a nerve racking job machining soft copper like this, just a couple of thou per cut was all i was game to take. Hope it handles the carbon brush well, as normal commutators are much harder i'm sure.



Just need to modify my brush holder now.

Sorry for the slow progress Guys, am busy with lots of work at the moment.

Hi Ufo, The toroid is wound with one continuous clockwise winding, every loop is connected to the next.

My first test will be with 2 loops bridged together at 180 degrees apart, just to give two definite outputs for N & S, but with my setup, if need be i can bridge any loop i want.

Also i can split the winding and make a brush wide enough to cover the split, so it makes before breaks,MAYBE, but I don't feel this will be necessary.

Like you state Friend, only testing will provide the information.

Regards Cornboy.

Open or Closed Loop?

Hi UFO, i don't quite understand what you mean, but testing will tell.

Best Regards Cornboy,

Hello Cornboy,

Yes, testing will tell, definitively.

Are you having a closed loop on all turns?

Or are you just using some dummy contacts (not connected to anything) just for brush to drive on smoothly but there is an open gap on some part of the turns?

If there is an open gap, whatever angle outputs be, there would be a point where brush will hit a blank (no contact point) unless you have all turns looped- closed.

At same token, I have been thinking what MM was saying before about having a full closed loop winding...which did not worked out...but maybe, just maybe it did not work for Netica or for me, because we were not wiping brush directly on windings...and like I wrote before...commutator goes faster than Part G loops...

It would really be a blessing if it would work with a closed winding...which I always thought it would...and it should, based on my previous repulsive field development...

Anyways, glad you are up to here now...being able to show us all, if it does or not...


Cheers Cornboy...we will get there one way or the other


Regards and many thanks for all your hard work Friend!!

Testing

Cornboy;

Setting the output at 180 from each other and testing will reveal everything. your set up will not jump from high to high as this is impossible so don't worry just test.

located a surface grinder for future, come to find out the business that cut my cores for free twice has one. woo who !

Looks very good.

Ufo,

OK, rewired the connections as requested. No way to get 3V 3A input so I did the test at 3A.

Input: 6.3V, 3A

Output: 11.45V, 0.51A DC rectified

18.9 watts in, 5.84 watts out
