Hi Hubert,

Okon Account,

The funny thing is that Okon has been giving answers to your statements here in RC Network for months / years. How stupid does he think his customers are?

Most of the time there are just answers like it doesn't work, it's not profitable, he knows better anyway, etc. The fact is that, as always, you fail because of your abilities and your understanding of why you do something differently. He doesn't have any technical training and just tinkers around more poorly than he can. It's like the Lehner 41/25 and 40 Tread where they didn't understand the engine. As a precaution, the load is not applied up to the synclos, as the actuator and motor could break. It's not possible to record the generator data any other way on an engine through measurements.

Then you only have simple electronic controllers available. Today, motors are no longer just operated like a brush motor. The electronics enable completely different performance curves that have nothing to do with very simple assumptions like those in Tread. It is not possible to determine the efficiency based on the speed stiffness. There are test benches to determine the performance data and many individual knife procedures to record all losses. The developer who designed the motor determined how the magnetic coupling was designed with the possibilities of today's electronics in mind. It's not worth discussing with you, especially not with Okon who wants to support the animal shelter. If he worked as a doctor, he could afford the animal shelter just by working a few hours.


Happy Amps Christian

Christian,

I knew at post #3. A spy can't fool me registering the same or the next day...LOL
Since clearly you are reading here let me say this. I don't think anyone in American hobby believes a scorpion is a higher end machine than a Lehner. I dont know about pilots but sailors certainly know who make the superior machine. Its no question. You know for yourself there's is only 2 names in fast electric boating that are relevant as far as I'm concerned. The scorpion may be a fine heli machine but its a hot hand grenade in a boat. The most torque demanding and if you look at the 7455 its mostly reactive power. U can see because it is not square with the torque output.

You know I'm the one that pointed out to you that the schmitt who Okon clearly gets alot of this nonsense from drug you motor down to 2 s lipo although it was designed for 10s to find one point where he looked competitive. It was a funny test and Thomas doesn't always tell the truth about the motors Chris. Then there's the epithet and Thomas's resentment of American English. See his DD 4225 is a noisy some bitch. To many parallel paths untwisted to be running at a kilo of fundamental frequency. It doenst matter to me what he says works it only matters that my efficiency is clearly higher and I dont have any pilots on the ground in smoke...

YET!!!

The speed troupe's common practice is to throw the competitors motors in the calculators on the worst prop they can find in the box for it. Then they run the optimized prop for their motors data collection. I can show you example of this If you do not already know sir.

Chris,
Its almost Jim Jones how they bury the truth and stay in flames for it


Thanks for your time and patience

Wenn Sie ihm das Drehmoment und die Sättigungsfigur des neuen 8057 im Vergleich zum 7455 zeigen, fällt der Faden schnell auf den Boden mit einem Verbrauch von 20 kW bei 7,62 Newton -Metern. Dies sind alles Unilog -Protokolle. Es ist keine mechanische Maßnahme, daher ist das Drehmoment nicht etwas, das es meldet

Seine Freunde oder reden nicht darüber.

[Clugh]

The advantage to the hot mess running at 2s lipo is low rpm so it runs a low fundamental where its problems wouldn't glare. He is a very slick willie Chris so you be careful with him. Test the Scorpion for yourself at the right voltages. If he used half the time he does hiding the truth trying to find it he would have a Hubertus post Doctorate award from ABB. Extremely cunning buddy. Also as you approach stall from 2s lipo with a heavy load the AC become less the point and the DC more.

They drummed up a test for yo as bruh.....

Danke
Hubert

[Clugh]

See what would happen to him if he runs up in the kilohertz......where 10 s lipo would have put him.....and stall is very far away. Do you see???

Slick!!!

[Clugh]

I'm sorry to break this news but Ralph is not fooling anyone but uninformed hobbyist and his customers.

Hi Chris,

You also have to remember this is not scorpions fault. This knocker was never really their direction. They do not sell it.
They run 14 pole A series in an airplane and it is a very solid motor. They also post mechanical measure so SCORPION is not the one that leads its consumer on. We really need to designate these motors separately from them . They gave dude a sandbox with some old parts to play with is all I see.

For that I do apologize because scorpions really does post the mechanical measure now and I think their Tribunis six step inverter is the ticket for a single layer scorpion. Thats a pure BLDC system and should generate alot of torque. All it needs is to add is magnovol wedges.

At all cost crocoworld is not at all interested in promoting the LRK six step winding scheme. If the YGE 320 actually had a heatsink you could fry a burger on it the way they drive it.

[Clugh]

What about an SOS winding
2.2 Winding design with star of slots


The star of slots is a collection of phasors which illustrates all possible phase shifts of the slot emfs. Each of these phasors is valid for t slots, so the star of slots consists of Q_b  = Q_s /t basic phasors. The counter t is the greatest common divisor of the number of slots Q_s and the number of pole pairs p. Neighbouring phasors in the star of slots include a phase angle α_p  = 2π /Q_b. The electrical phase shift between neighbouring slot emfs is α_e  = α_p · p /t. In order to label the phasors with slot numbers, start with slot 1. When incrementing the slot number, jump by the electrical angle α_e to the next phasor. If you stop at slot number Q_b, each phasor has its first slot number. If t  > 1 you will get the further slot numbers for each phasor by adding Q_b,  … (t  − 1)Q_b to the first slot number of each phasor. Fig. 1 a shows an example for Q_s  = 36 and p  = 7. As t  = gcd(Q_s, p) = 1, the number of phasors Q _b equals to the number of slots Q_s. Adjacent phasors include an angle α_p  = 10°, and the electrical angle between neighbouring emfs is α _e  = 70°.

You are welcomed for the download and another winding scheme you didn't come up with.

Man that's not on this site subscribed here.

The case conversion on the 5040 has been completed.
If anyone is interested, please PM.

In the unfortunately deleted thread, the mechanical engineering company FH had explained, among other things, how advantageous it would be to wind a speed motor with anodized aluminum wire in its opinion. If anyone should now feel like trying it out for themselves (his suggestions are always very interesting, but regularly fail with him because of the implementation), I would like to provide the wire shown on the right.
This is a transformer coil from early GDR times, where the lack of copper was often compensated for with aluminum as a replacement.
But I warmly recommend to calculate the whole story beforehand - as we all know, the motor does not only consist of the winding. Appendixes

~powercroco~


So we can see you are concerned about what Lehner is doing. Firstly i can tell you its wrong the wire he uses will not be shaped like this 2 he has a magnet system in his rotor that is beyond your understanding as it actually injects triplen in the right places. We will let you go out on your own and research why that works. He's working on a magnet compression system that focuses flux that's why he keep showing you the triangular wedges from the motors they did at his place of professional engineering employment. You know the guy happens to be filthy rich and drives a Ferrari from his engineering work Ralph. I hope you not jealous. I have photos from the rotor proposals you have never seen. He had these probably 3 years ago I guess. So i guess he will finally decide to show you all all this time later.

and isnt it unfortunate "beinadic arnold" got the thread erased.....



If you post the motor constants to the CoFe Silly putty I can tell you through mathematical calculation roughly how much more efficient my speed motor will be. They will also run much cooler and take more amps. If you don't believe it post the constants to your "speed" engines. How much do they cost again ??????

We've never seen a price in years for the fires i know its at least 800-1000 euros to burn

If christian was smart he wouldn't return to RC network he come aboard here and pin you here for the rest of your life to learn from him just like I intend to continue doing. U have to leave your croco world forums in Germany and abroad to actually learn something.... they're all dead Bruder. 👀

To me he needs to grasp that the forum is not worth his time if the information he takes the time to post is going to be censored. Its very valuable information from the ELDER engineer that helps the youth and industry thrive. You really should be ashamed of yourselves and he should make you pay for it by not sharing direct. You started that fight continually mentioning that mans name and motors in your post then when he snap back you want to time that man out and erase his information that's accurate and proven. You know it isn't fair.

He should start a blog where the visitors are plainly shown and he can erase comment and posts unwanted. He needs to control the release of his information under his terms.

Christian just needs to become empowered and understand he doesn't need a forum that doesn't need or want him. Anybody and they moma can start a self controlled blog. You wouldn't speak there because the rebuttals wouldn't be censored.

I could write a manual on motor design with all the information, photos, and diagrams, from the highly successful Patent holding German engineer you all have censored over the years.

Okon the Schrotthändler

Hi Hubert,

We don't care about the troll who keeps running after you to finally learn how to optimize electric motors. But why should you bother with a scrap dealer who is still trying to clear out his junk parts box?



Who keeps the old welding transformer from communist times? With some kind of insulation on the wire from GDR production, you can just use house wall paint. But in all the years he has owned the scrap, he could have simply wound two coils with the same connection resistance and the same number of turns and compared them when loaded with high currents. He couldn't even manage that. There are reasons why the US Army has us develop its new hybrid electric tank drives and not ask the scrap dealer.

Drones are now flying at over 500 km/h with small 450 gram drives and 1800 mAh batteries. They can do this without any downturn, free fall energy use. They just fly straight ahead. Their propellers run well into supersonic speeds at a circumferential speed of 1600 km/h and more without anyone getting upset about excessive noise. The pilots don't even wear hearing protection. 7x11 APC propeller with over 50,000 rpm.

They should give you a 100 volt fun class drone, that would be fun.

More importantly I want the hobbyist to note he will never release the motor constants to his "flagship" speed engines because he does not want them to see we run much better in all the calculators. He tried that once with his 1 milliohm 4225 LRK DD with astronomical idle currents and ended up with a max Eta 3% less than our tuned LRK YY motor which was 5 milliohm. He cannot explain why a motor with 5 times less dc resistance is outperformed as ours had 1.5 to 2 times more throughput power than the scrap iron 4225 from powercroco.

That should really matter to anyone not living in Jonestown.

"DC" man cant explain it because all he knows is the DC resistance at room temperature and has no respect for the AC losses at all which are 10 times the DC......

You can PM him to buy his engine because the price to burn is so astronomical.

In a week or two Ill give you a motor that will actually be competitive against the fastest in the world. I promise you that. His fans are loyal but none of them will post the constants of a 5040 or 5050 at this time. They are equally scared to have their hearts broken by "POCBOI'S innovation. Their thumbs up are all brown. 💩


If they need a refresher on the comparative numbers we have that.

Thank you
Hubert

Good luck with the back door politics ...

Wegen dir und deinem Mund baue ich eine exklusive Compound-Speed-Maschine! Leichter und effizienter mit mehr Leistung. Ich hoffe, du bist bereit, verbranntes CoFe zu riechen

Danke
Hubert

[Clugh]

Es wird auf Christians Hämmer und weiche Ecken mit breiteren Zähnen als ein HK überarbeitet, bevor ich es schneiden lasse. In ein paar Tagen. Aber vorher habe ich viele Möglichkeiten, ein 5050 zu versenken. Es braucht kein exotisches, teures Material wie CoFe, um gut zu funktionieren, was anscheinend nicht der Fall ist, da die Desynchronisierung durch seine Verwendung nicht verlängert wird, was daran liegt, dass der PM ein ausreichendes Feld verliert, nicht den Kern.

[Clugh]

Christian, du hast eine PM über deinen Musikerfreund, der nicht weiß, wovon er spricht. Er ist extrem nervig, da er überhaupt keine Windkraftanlagen baut oder betreibt. Keine Erfahrung! Außerdem möchte er nicht zum Krieg beitragen. Warum also steht er jetzt hier und redet?




Thanks
Hubert

Er schämt sich nicht, zu reden, wenn dies der Umfang seiner Arbeit zu diesem Thema ist, oder er lässt Duane Hanslemans asymmetrische Winddiagramme wieder aufleben, die ziemlich laut sind und einen kW-Wert von 0,90 haben. Er weiß nichts über das Zeug, weil er es nicht aufzieht und dann analysiert.

Well, if it's interesting for you, you can do it.
I won't post results here, because the main interest is to use the values to fuel the dispute anyway.
By the way, Hubert wrote years ago that with such small motors, the winding heads become too big.
But you'll laugh, I was still interested.
I have such a vintage high-decker that beeps terribly at partial load, I didn't get it minimized by the controller settings so far that it is no longer annoying.
The Y-D runs very quietly.
You can also optimize for things other than speed flight.

Crisco,

Since he is talking now in the middle of the "WAR" tell him to post a photo of the y-d hybrid he wound. He's lying and doesn't have a single piece of data on a hybrid machine. Trust me. I haven't even seen a conventionally wound motor from him and neither have you or Ralph. The editor there is truly useless on this subject matter.

I also never told him that about the winding heads so the man does not tell the hobbyist the truth.

Here is a Y-D hybrid pyro right here... and I can wind and 4 layer motors no issue so I have no idea what the hell he is talking about.

I guess the "Anglophile" in the Cambridge UK has a more extensive skill set than Rennsemmel. He followed my directions and wound the motor in a day.

Sebastian has had 4 years to produce nothing but an empty stator. This is why BLOGS are good you can remove the nonsense!







Thanks
Hubert
