Alternative motor windings and drive schemes

[Clugh]

Ralph you are here reading so you are welcomed to post some relevant data on the German social media. I told you youd be corrected on your own forum.

You see I still have a little pull there. 👀

There is no reason to be mad at Thomas or Christian. Clearly the reason Thomas brought up the single layer is because it has a second level of copper coil on the tooth if it is equivalent to a full bobbin dual layer.

Fallacy wont lead you to new successes in motor winding. You need to get beyond that.

Yes Thomas's windings are darkened here Ralph and pilots can run the motors to overload. But that is the same for all of us . The question is how well is your motor getting rid of the heat at those times. As Lord has shown its critical to the seen resistance of the wire.

Hi
While they figure out if thermally conductive compounds work. The flux barriers for the split tooth will be made from PPS so I thought id share the materials numbers and the challenges to print it.

It doesn't happen with the ender3 I've been playing with.....

2 more 600s down these are Randy B's pair. They go out later today after I pot,terminate and measure them. Then run them idle and with a load on the bench.

Hi,
these are flat coils not upright as you describe it.

Coil with iron core, the larger the iron core, the greater the magnetic force. Try to lift a car to the junkyard with an iron nail and a thick large coil and then you do the same with a large iron core but comparatively quite small coil, which lifts the car without any problems.

At least you could have looked at the picture.
This shows (for me sufficiently clearly) what is meant by flat wire upright.

What you meant by iron in the coil is now clear. You mean the core, not the winding.

Wouldn't you like to finally answer my questions?

Ralph I sure hope Christian doesn't answer a fallacy driven question asked by someone with no formal training, experience, or education in any of the fields of engineering. Does his answer make the result any different with the wires .

And that this has nothing in common with a real potting.
It would look like the first picture. ALL spaces in between are completely filled without bubbles.
this is only possible with vacuum - although even the potting compound must be degassed beforehand if it is to be good.

Not as in the sketch above, that nothing of the smearing between stator and wire arrives (light green area).




It always depends.
The changing room doesn't have to look like a piece of cake.
4+2 single layer. Appendixes


And so we have confirmation that it was you that traps in heat and no you are wrong thermally conductive material with a density a 3rd of full still ran 30C cooler. Even with voids the TC is superior in every way. Your ideas are invalid as you have not verified you understanding which is lacking you see. Reread the study.

I am glad you can copy and paste the VIP from Motor solve. I posted that for you years ago. Glad to see you still know how to retrieve it but you idea the something is smeared is totally wrong the TC is in between the wires and the stator tying them together.

As far as Thomas Is concerned securing wires has nothing to do with their thermal conductivity.

[Clugh]

All this bull **** to finally decide you wont use endfest anymore. And still lack understaning to think you need 100% density to have positive effect . Thats is not even remotely true sir, The studies have shown even if there were hot spots it out outperforms bare wire. Seem like you there in Germany cant read very well.

LOL

[Clugh]

You all cannot read!
Sad...

No difficulties in vacuum filling were noted with LORD SC-320 despite its viscosity being somewhat higher than those of the epoxy and varnish. In addition, the potting compound was effective at decreasing the hot spot temperatures even when the potting was not 100-percent dense. For example, the hot-spot temperature of motors potted with LORD SC-320 increased by only 3-degrees-C as the potting density was decreased from 80-percent to 50-percent, whereas the hot spot temperatures of epoxy- and varnish-potted motors increased by 19-degrees-C and 25-degrees-C, respectively, as their potting densities were lowered from 80- percent to 50-percent.

Nategh’s research showed that hot spot temperatures can be reduced by 35-percent to 50- percent using LORD SC-320 material as compared to an un-potted motor, compared to improvements of only 20-percent to 30-percent using typical epoxy potting materials. The potting compound may provide significant improvements in power density of electric motors.

A decrease in the hot-spot temperature of motors, depending on current, may provide an increase in achievable power/torque for a given motor size, decrease in motor size for a required power/torque, and longer motor operation before reaching temperature limits.

[Clugh]

Do what Thomas said and dont pot it.
Im fine with that. You'll never reach my efficiency!

[Clugh]

So Ralph has finally stopped using endfest!!!!



What I tell you.....

You don't realize the TC compound will add to the longevity of the coils as well. Thomas cannot see what happens with the wire at these frequencies so the idea they secure themselves is nonsense. It also depends on the wind. Hardly every wind will pin all the wires under the hammers .

No real motor builder secures the wires with themselves.

Thats silly

read it one more time

Too funny based on the expert accounts there at what it must be to work effectively. See that scorpion fans? Once again the man is incorrect about the necessity of vacuum impregnation and 100 % densities.

And he wont run cooler and be as reliable with nothing holding the wires. You can see from the graph that as the torque demand rises the effect of the thermally conductive material becomes more advantageous.

Hi,
upright says, narrow side down and long side stands up. In the stator groove, the narrow side in the groove base and then the long side according to the groove depth. Everyone knows what is meant.
For all those who do not know Hubert's results with the Contradrive, https://www.hobbysquawk.com/forum/e...indings-and-drive-schemes?p=406894#post406894 .
Page 50 Answer # 986 and in German # 987 etc. . Lots to read. Okon is the secondary school student there and is constantly learning. Borat.

Okon ! You have to search : "Semi-automated process for the production of connectors and Y-distributors for quartz glass cappilars" that is for gas cromatography
I don't show it, the process and how to make an oxyhydrogen burner whose temperature profile can be infinitely adjusted is in great demand and has worked without a patent for 36 years and earns a good income.

Hier ist Ralphs gefälschtes Profil.

Angeblich ist er BOHO1


User Profile - Hobby Squawk RC Forum for Airplanes, Boats, Cars, Helicopters, Tanks, and Trucks.

[Clugh]

Which university?


Thanks for the link to the forum without rules.

So poor Hubert has been given an undisturbed place for his 3rd sprawling soliloquy, after he has been blocked everywhere else.
Really nice.

In any case, I am definitely not registered there under any name - why then?
I would even bet I know who this other BOHO is. I'm sure you know it exactly!
You must like that - without any rules of etiquette or copyright protection.

As far as I can tell, your ingenious counterpart has copied an ancient winding on the Pyro 600, because Bert has stopped.
Too bad, Bert was one of the really good winders!

So there we have a 12N 10P 3225 with thick wire second layer winding and YY termination.
The whole thing is even smeared on the outside. This is certainly helpful for the loose sheets in the 2nd position.

Nothing from Gerling, Y-D or river barriers.
Thus, according to your reading, worse than what MM did 25 years ago.
It's great that you suddenly find this interpretation excellent.


And what could they have learned there? Schmiddie has already commented on the senselessness of the smearing in January.
He probably didn't understand either.
Unfortunately, I tried to find out why exactly this is the way it is.
(which wires it hits first)
Well, the explanation was apparently pointless.

It's especially cool how he attaches himself to the fact that one of my windings with one of my windings performed worse or better in the DC comparison. cool. The normal series dispersion of 2-3% is the measure of all things for him, which is what it turned out the right way around. Really clever head.
Although that's easy, everyone else except him and you are STUPID.
Yes, that's the worldview of real geniuses!

Somehow he still eats your tool - he writes there what you don't dare to write here.
Even your special mails - you obviously agreed to the publication.

ALL the windings on the Pyro 400 were initially made by me until Holle was ready to take over.
I have attached a photo from this (primeval) time.
Micha Schöttner's mfly special scheme was used. But you can see that.
At that time the stators were still coated blue - they are the same as on the 14P Kora.

The 2nd picture shows the single-layer winding, which was rejected by Kontronik around 2008 - too cumbersome in winding and it would have required a housing change (high winding heads at the top and bottom).
The YY was also available, it failed because they didn't want any solder joints in the motor.
So the two-layer winding in D was terminated.

As far as Hubert's intention to get involved in the WSM is concerned:
Thomas will certainly be happy to reserve him a starting place!
You can get to know each other personally.
And you can make his caller.

LOL its definitely you Ralph and it isnt off topic Kai because he ask Christian for his professional credentials in engineering when ralph has none. And Kai you have to fly it special to keep it from burning up. HE POST THST HIMSELF. Also Ralph Brenner plans for me to ask Andrew to fly my plane but Im sure someone else in Germany will fly it as long as im there, Also i dont need your official trap to post a speed Ill be with a top dog Futaba with GPS so Ill know the speed regardless. If You wont let my plane in then I win by default.

You need backyard politics to keep my plane out? You nervous ? I know you are.....

The forum here is no different than the one there that let you use racial epithet even in your signature

what are you talking about bro? Im here showing my guys how they can make their motors run better you post I need to study but my numbers are better than your and that consistently stays the same. Ralph

And what about DZ will anything last a month? I mean you brung back a pile of burnt YGE's and motors from 2024. KAI is about the only one that survived flying special....

And Ralph you blocked on forums the same way for doing the same thing you doing here. Impersonating me....either that or closing yours if i get to many thumbs up.

You are just mad I don't need to be on helifreak to take the food off your table there.


Thank you for you time and patience.
Hubert

[Clugh]

The problem is my motor is a 5+5 Berts was a 6 + 4 and that's the point Ralph its consistently running alot less battery than his. The first difference is I use TC epoxy he used endfest.

Make sure you understand it clear from the world class pilots mouths....

Most likely he quit because of you since his pyro motors were consistently taking your scorpions out of the helis on the freak..

Andrew never flew a Bert Dekker motor . The 8 + 8 in 17 AWG didnt come from Bert....Its is totally my idea Ralph

Brenner drives and their pilots were very happy with Berts 600 motor but

The last 6+4 600 burned up on the ground in a static test by the pilot and he said the first thing he noticed is the endfest was soft....

The pilots state emphatically that they have had significant improvement since then with significantly less power consumption for the same job. hey also run cooler.

Brenner drives reports consumption and temps lower than they have ever seen. Andrew reported 10% better efficiency in his 25P program with my interpretation of a competition wind.



Hubert

[Clugh]

It really doesn't matter. I'm not going to waste my time like this. We plan to build and wind 100 50mm composite speed motors for anybody so it is what it is. They will see Germany . I'm sure of it.


The 2 pyro 600s from earlier are thermally coupled and curing now.

Moving along... because im also sure i can handle a 150 dollar vacuum pump. in my 1000 square feet of workspace...

Thank you for your time and patience.

Winding losses and their cooling | RC-Network.de


Hi Guys
Read this thread in its entirety and you understand why we call it crocoworld......

[Clugh]

Something useful from it we can think about when building motors for flight.

On the Tread topic:
for the electric flight speed drives with the very short running time, a motor with an aluminum wire winding would still be the best option.
To get the same winding resistance, the wire diameter would have to have 68% more cross-sectional area. This requires a correspondingly larger stator. Can be more diameter or simply longer. This increases the stator surface, which is responsible for the rotational thrust. A machine with aluminum wire would have more power at the same weight. In addition, the aluminum winding has a larger surface area for cooling and what is almost the most wicked aluminum has more than twice the heat capacity of copper. So it can absorb and store much more energy (energy loss). In addition, aluminum can be insulated by a thicker anodizing layer. No plastic. Anodized, aluminum oxide is a ceramic that does not burn out. Ehr melts the aluminum inside. This gives you a much better insulation, which can be super tight and highly thermally conductive in rectangular wire cross-sections. Loss heat transport as no plastic can offer. Just think about it. Proximity losses are also lower with aluminum.
