I've just built a pulse motor testbed with precision bearings. I will be experimenting with DEK UCC on it first.

I have not started the software yet, but initial specs are:

timing phase (10th degree resolution)
timing pulse width (10th degree resolution)
show RPM
show input power (true RMS)

I've ran the motor up using just the reed switch and it runs OK. The magnets are diametrically polarised, the poles appear on opposite sides of the circumference, the coil is 6cm diameter circle, 100 turns of 30AWG.

I am thinking of experimenting with shorting the coil during the exit phase by using a fast relay controlled by the micro, I'm hoping that maybe the perepetia effect can be made to appear and the BEMF can provide a physical kick out.

@ yucca

almost      a swiss master piece

yes i am very happy that somebody takes the time to really experience the UCC  and how it  works     and not only how it works,  but you intend to do what i am not knowleged enough (yet)  to do    that is studying  the details of the  working principles

and  the output possibilities of the collapsing field

thank's a lot

@Ramset

This thread  is  the first  one where i go in       but i have in mind that we all have to do something to overcome a very mondial critical situation.   I can say to you that   3 years ago i  probably would have spent easily 10 000 euros to patent each of my ideas     and i  did  it   for the 3 previous decades      and i have really spent  around more than  100 000 euros  for that .    Furthermore  i was very  sceptical to open my brain to this forum    but it happens a very special history to a good inventor friend of mine       he patented one of his idea  (a very good one of  course)   the patent was world wide granted     and of course he spent   the mondial fees for that  and each years of course    and i can say to you that there is very    very expensive    and 9  (nine )  years    after   the worlwilde granting         a big company  got  interested to the idea   and as this company pay lawers at full job   they always come to results    and they found a failure in the patent     result patent     zero         think of it       !!!!!!!

@all

i am going on for the torquy DEK motor

the magnets are here  and now  lets go to the details   i will need probably 3 to 4 days to make the magnet holdings on the wheel + one or 2 days for the axle organisation


so the helpers  have  2 or 3 days from now to inform me   how about the coils          Gauge    turns   bifilar     i have  heard  of      Bob Teal       winding  (very interesting)  with strong  energy recovering  ?


input power      one  KOKAM lithium polymer  battery  40 AH ( 40 amps)  14  elements of 3.7 volt nominal  = 51.8 volts         4.2  volt maximal  at end of charge voltage =58.8 peak volts

input power  max 300 amps at  50 volts  = 15 000 watts (15 kw) max  for 1 minute

than about 6 to 8  kw for cruise flight


bravo a tous !

Yes Ramset i have some knowledge   and very wide  but not so precise as you think    that's why i need you competence to go forward

Thanks Laurent and Chet, it´s not as pretty up close as it looks on the photos . I only have a hand saw for wood and one file and no vice so my hands are still aching. I bent the acrylic on my gas stove and also put lots of tiny bubbles in it.

I will make a special strobe light: I will put red and green LEDs pointing at the coil, and stick white circles on the magnets, then I can light the LEDs with the micro like this:

Green for the coil on time.
Red for the coil short time.

This method combined with oscilloscope over the coil should help to get a physical feel for what´s going on.

My progress will be slow but steady, I have about 10 spare hours a week for doing this. I predict the microcontroller will take a couple of weeks to program.

Nice set of magnets you have Laurent, I will keep looking in regularly at your experimental building.

Also I may understand what happened when that outrunner delaminated a magnet:

The nickel coating might have had a tiny imperfection where it was not stuck properly to the magnet, the imperfection could have been very tiny.

During takeoff (max power) the tiny piece of nickel foil with air underneath got heated through eddy current and began to vaporise.

As it vaporised it made the imperfection larger and so more nickel foil became free, this caused more vaporisation etc. a runaway explosive effect.

To cure it you could remove the nickel coating from your magnets (use slow electrolysis through nickel and copper salt mix) and then recoat your magnets by dipping them in epoxy marine paint. I have never tried this myself so try with a scrap magnet first.

@woopy

In ucc-boxing.jpg, area marked 'match null'.....
Please be aware that beyond an unknown distance the net will not be zero or even close to zero. If the distance is too great you should find one end of the magnet using attraction as inverse square while the other attraction is inverse cubed.
So, basically I suggest minimizing the distance of magnet travel from one loop of the coil to the other loop.
This distance will require experimentation. In any case the net should not be exactly null.

@BEP

I agree the relation between the length ( N-S) of the magnet  and the UCC legs is probably very important.

Have you some idea of what to do for the begining   i have thought that the length of the magnet (N-S) would be the half  of the gap between the UCC legs  ??

very good your magnet test system with a Ampclampmeter   very instructive comparisons

@jadaro2600

exactly as you said it is very simple to do    and you will see that it works very well   i don't have movies untill now

@all

and now i have to buy a scope to inspect  the details

i am very happy to learn a new matter      as my favorite one is aerodynamics and flying machines

good night

Laurent

hello  every one

he he !!  :  )what about  the idea of a n   UCC insider rotating magnet 

i made a bigger test to night with very interesting results     as of the the distance  and the separation of the legs   and and and    so here some pictures
see the difference between a "squared  UCC    and a flat UCC   the power different seems to be very linked to the geometry of the UCC




very very intersting

good night

laurent

@ all

i go on to understand better the UCC working principle

the rotating magnet inside the UCC is more complex that what i imagined     but very interesting

here under some of my last understanding of the UCC

some of the pictures have been taken out from internet  (so i don't know if there is any copyright   but as there is in private and good way use, i think there will be no problem)

just something in the last picture they say     "Work is done during the motion & it is transferred as electrical energy "   so if the UCC will need no (or very little)  WORK  (because Lenz boxing against Himself   if it is!!) 

how is it possible to get it working  as a motor or as a generator

commentar are welcome

Laurent

Try this!!
It will charge batteries as a bedini motor.
