Alternative motor windings and drive schemes

[Clugh]

Chris, Ralph ist ein lustiger Typ. Wenn man darüber nachdenkt, ist es lustig. Er fühlt sich wie ein Weltmeister, weil er an einigen Hobbywettbewerben mit, was, 20 Leuten teilgenommen hat? Sag mir, wie viele Leute, die nicht aus Deutschland sind, bei diesen Veranstaltungen sind. Wie groß ist die internationale Verbreitung dort, seit er Weltmeister ist, und wie viele Motoren hat er bei Wettbewerben verletzt? Wen schlägt er also? Sich selbst? Und seinen Freund auf Crocoworld, das ist ungefähr der Punkt.

Sollen die Verbraucher dann aufgrund dessen, was er in der Vergangenheit getan hat, 5,62 sm für 20 kW Verbrauch vergessen? Das ist schrecklich für jemanden, der behauptet, er hätte die Milch bekommen.

[Clugh]

Er mag seine Oldtimer mit fossilem Brennstoff und Sie mögen Lucids und Ferraris. Sie hätten von Anfang an wissen müssen, dass der alte Vergaser nicht zu Ihnen passt!

[Clugh]

But Chris
I wouldn't worry about it. I still have 1 more pyro 650 to wind for AJ. Then we can start the experiments. I have several big bodies to put the flussperen stack and hybrid windings on.

Hi Hubert,
yes, very funny! Manufacturers such as S. Neu, H. Lehner, Kontronik, etc. manufacture their products using certified processes. As a result, customers receive a product that adheres to tested materials, production methods and processes, and the product adheres to the manufacturer's instructions. That's not so easy these days, there's a lot of bureaucracy behind it. The speeders don't bother with that at all. Okon's engines are sometimes better, sometimes worse. No one knows what magnet qualities, what wire qualities, insulation, etc. are distributed. In addition, not everyone is Okon's best friend and so Monday's engine ends up with the not-so-loved one. They have built a castle of material that is only produced in small quantities and so only those who submit to the circle have access. Anyone who wants to move something from outside without access has a very difficult time. If you're not loved, you won't get the plane you want, the propeller blades, etc. or he only gets the second choice, which has errors. So they're basically just fighting against themselves. Whether the rules can really be adhered to, believe whoever wants to, I don't believe anything anymore. Stick with the aerobatic pilot projects, things are open and normal, honest. You get realistic feedback and can build on it to improve further. This is worth a lot more than the three-man circus. And if you enjoy it, we'll try some new engine concepts.

Hi Hubert,

now it gets really fun. Okon writes about manipulated measurements and attributes it to others. The truth is that only Ralph Okon embellished his measurement data with such lowest no-load current values at low voltages, as did Gerd Giese. There's a thread about it, I saved it, in which the two of them discovered it completely by chance. Many of Okon's other measured values were also very questionable, such as his glove brake for a very short time when the engine was still ice cold, etc. Those who were paraded like this also clap their hands under his post. I always measured my engines on a test bench. Only hobbyists come up with the stupid idea of determining the efficiency based on the speed stiffness like Okon and Thomas did. There are very different magnetic couplings and therefore desired designs with regard to speed stiffness. Uwe Plettenberg's F5B competition engine also had a design that dominated the vertical electric glider world championships for decades. Only Aloys knew what it was about and wrote that such an engine would really increase in speed, but the others were already at the end. I also set up engine maps in the thread that showed exactly that and asked them both to explain why such maps are reality. They couldn't write a word and explain it. The fact that we do this with FOC controllers today was also dismissed. But Thomas quickly got a controller like this and used it to run his electric go-kart with a Lehner outrunner, proving that things are completely different. The Lehner much, later. reach synclos. They also recognized the benefits later in the synclos but didn't implement the benefits. In addition, they haven't understood the magnetic coupling design, so why should we further clarify that? Pointless!!!

....and didn't I ask for 90 days of silence to watch nothing occur on German social media?

I absolutely agree with everything you have said here. I understand very well the racket being run there on the poor souls in Germany , America and abroad like Dzhamel who continues to choose to believe after burning 20,000 dollars on Okon and his friends. He has 1 speeding ticket over 600 and plenty of DNF's

I don't want the bad karma of A-boy anywhere in my models.

Straight up.
His "academic" unpublished theories as an uneducated amateur mean very little to me. What else can he say about an engine better in any calculator or model you put it in..

Why would anyone believe a person so aloof that they float all the way back to a German forum to respond in eastern cyberspace when their right here on this forum everyday signed in under my handle they have perverted.

I appreciate his "honorable" mentions....there but Im right here....

Why not mention the 800 mah less I consume with the Pyro or the noisy ass 42 you wound that could not touch the Align A boy? The eta was 93.5 of the comparative scorpion you wound in your own calculator....

The idle currents of the parallel buffoonery he winds are astronomical and he takes motor data at zero degrees timing which is nothing but cheating.....because they run at least 20 in the planes to pull heavy loads.


Nuts.....
Hubert

[Clugh]

A 50 dollar Align from a Heli freak swap meet is only on his mind as is a conventional YY that is also nothing to me as mine on any motor brand already runs better than his end fest potted nonsense that keeps burning up year after year. 8 now....



Have a good day and be constructive. I have real industrial responsibilities that feed the world the best material for ALL electronics today Including those in Germany. Rc models and its equipment are just my hobby and he is just a hobbyist.

He is subject to say anything but it has never affected the trajectory of my professional career in the extremely relevant field
As truly accomplished hobbyist in internationally recognized rc flight championships with a wide field and brand spread You are better off to ask Andrew Jesky or Brenner contra Drives about me.

Powercroco is just a Jealous lil' aryan op that stays in my motor winding school here everyday as me. Why else would he draw up a profile signature like that and try to use my name as his?


~ boho1 on here doesn't feed black trolls there on the German social media~

boy bye...these are not the kind of trouble makers I even think about with much energy. They clearly do not have my ability or inclusive heart.

He will never be blessed.


Thank you.

Für mich ist das alles albern und von Clowns ohne Autorität zu erwarten, denn alle Fehler der Welt aus allen Richtungen ändern nichts daran, dass die Motoren weit über ihre Grenzen des zuverlässigen Betriebs hinausgehen, obwohl sie angeblich speziell für den Einsatz im Hochgeschwindigkeitsflug entwickelt wurden. Ganz zu schweigen davon, dass der deutsche Redakteur keinen moralischen Kompass hat und daher kein Problem damit hat, einem Forum über alles und jedes, einschließlich Hubert, direkt ins Gesicht zu lügen. Sie müssen bedenken, dass er seinen dummen Freunden erzählt hat, dass ich keine Motoren aufziehe, sondern nur ein Praktiker der Theorie bin. Obwohl ich nicht weiß, wie man etwas in die Praxis umsetzt, wenn man es nie tut. Sehen Sie, so ignorant ist der Amateur.

[Clugh]

Since these post I've received request for 3 more pyro 600's with the last request coming from Anthony Romano. Do you think for one minute the F3A pilots care what someone says if they can consume 300 -800 mah less in their application? Ha! the serious F3A boys don't even know who powercroco is....and they certainly wont fly an HK when scorpion has an airplane series that's totally different.

Dont worry . Let him throw all the shade he would like. Nobody is listening to this man as the orders keep rolling in. It would probably have been beneficial if his fallacy could have actually slowed the orders down a bit coz id actually like to play and experiment with my own stuff.

This is becoming too much. As it is just like having a second job!

Hi Chris
Apparently what people like Okon dont understand is i have better things to do than worry about an op from overseas. I just purchased a 2024 Suzuki RMZ 450 2 days ago and another for my son this Friday upcoming. While people have nothing but boring forums as a pastime were out living a quality life full of fun and adventure for Father and son. I care so little about this or powerditto its pathetic.... The bikes are fuel injected with programmable engine management Chris and can be optimally tuned with a smartphone. $10,000 directly off the showroom by Friday Ill have another. What is a 2000 airplane and 20 Germans flying them to me? Nothing really. Im more interested in my smart bikes that he could not ride without killing himself.

THEY ARE TOO MUCH POWER FOR BOSLEY. THE REST OF HIS HAIR WILL BE GONE 😂

We stay on 12 acres we own with a 1000 square foot shop. My lathe is not dirty and beat down and I know how to use it so you have to ask yourself do you think I really care what Jurassic park and its inhabitants have to say?

What makes it so bad is I already have a 2000 plane and 10 times better equipment just to sponsor the ass kicking and have never even flown. ....put motor in it I wind and he will be asking Thomas to keep me and any plane im associated with out his little speed competitions will be the result.

Not very competitive at all.

[Clugh]

Christian,
Ill show you more real pictures of the bike when I get home. When I finish my few winding jobs today ill be out riding my new bike, not thinking at all about the goof troop.
Professionally my employer gave me all top marks in review & I got a raise 2 months ago as well as an offer from the big boss to apply as the lead but Im not and do not even want it.

Im enjoying life too much for the hassles...Its SiC ning...

I don't care about anything right now but God, my family and my money. I'm not goIng bald trying to hold on . I dont drive stock trim old Beemer wagons.....and school teachers don't make any money....

My mother is 86 and even she's to hip to drive that thing...... she wants a new t8 s9o



Thanks
Hubert

Were all on here now at this moment and we know where ralph's engine fell in comparison. If his dense friends have forgotten that already that's there problem. They drink kool aid in Jonestown. You can go see how it lost on several forums with more waste an lower powerdensity. Take the constants and put them in any calculator then put that pos 4225 in there and see what youi get.


2nd place. and not even 94% Take any Io you want at any voltage and Im considerably better than that.

The 7455 powered surfboard what a joke

[Clugh]

Empirically the worst performing e surfboard in the class! U hear all the ventilation of the impeller? Is too small for the size and weight it want to push. Im sure the amperage is reduced by running such a small one. Its making no real speed as you see in the video compared to the better boards with better motors and drives!


Do you at crocoworld see here in the video of the scorpion powered surfboard.

You think this Slurpee of water outstanding?

there is absolutely nothing high performance about this inadequate ass drive.

HA!

[Clugh]

Empirisch das leistungsschwächste E-Surfboard seiner Klasse! Hören Sie die ganze Belüftung des Impellers? Es ist zu klein für die Größe und das Gewicht, das es bewegen soll. Ich bin sicher, dass die Stromstärke durch den Betrieb mit einem so kleinen reduziert wird. Es erreicht keine echte Geschwindigkeit, wie Sie im Video sehen, verglichen mit den besseren Boards mit besseren Motoren und Antrieben!

Sehen Sie sich hier im Video das Surfboard mit Scorpion-Antrieb an, das Sie bei Crocoworld finden.

Finden Sie diesen Slurpee of Water herausragend?

Dieser unzureichende Antrieb hat absolut keine hohe Leistung.

And about the heat of his engines in real operation

The increase in winding temperature gives an increase in
copper resistivity according to the formula:

NOMENCLATURE
ρ = electrical resistivity
α = thermal coefficient of the electrical resistivity
μ = magnetic permeability
kh.e = hysteresis and eddy-current loss coefficient
τ = magnet full pole pitch width
k = thermal conductivity

ρ = ρ20 ⋅ [1+α (T − 20)]
where ρ20= 1.724 ×10-8 Ωm; α= 0.00393 /°C
Thus, a 50°C rise gives 20% increase in resistance and a
140°C rise gives 55% increase in resistance.

[Clugh]

They say my thesis on ferrofluid is a joke but let see what the other engineers have to say about cooling...

Heat can be
extracted through conduction, convection (natural and
forced) and radiation.

Conduction will depend on the thermal conductivity and
dimensions – length L and area A – of the modeled region,
with thermal resistance given by:

Rth=L/kA

where L isn the length and kA is the thermally conductivity area.

[Clugh]

The motors can be wound exactly the same but there is no way if hes using end fest or not potted at all he will defeat 3 or 4 watts per meter Kelvin of thermal conductivity which is key to conduction cooling . Were right back where we started and his methodology is still inadequate! Based on Dr Dorell 34 degrees C would equate to around 15% increased resistance. 1 140 degrees C is 55% higher resistance. At the level of heat displayed by his scorpions he sees as much as a 60% increase in resistance. The engines arent making any real power thats why the torque and consumption are so out of sync with these severely overloaded motors. They wont last as you can see.

[Clugh]

I could wind a 7455 and it would run cooler even without the thermally conductive materials because I know how to do more to cool the windings than a internal cooling jacket on the stator. My windings would be directly water cooled and flow much more current. Dont worry ill build several big motors soon that will laugh at a knocker.
