Tata surprise!!! you love it right?



Hubert

[Clugh]

Got ya again..... You generated it not me.....

Thank you baby you need to clean his teeth!!💩 & do not drink the kool aid.
Hubert

[Clugh]

Dont sit there and stare at the top of the visitor list go ahead and explain it playa.....

[Clugh]

[Clugh]

Come on Christian! I dont have all day. You want to show out on a forum so come on... you can use fallacy ill stick to the facts. Come on buddy... lets go the chart YOU LOVE show less than 85% at 1.5kA and we also need to see the inverter and operation at 997.2 C

Holle's calculator says 93 is the max eta. and it occurs around 6kW just like the Lehner charts of his dyne meter. Just like skylar ya friends site and the Maxon eq 1.92. they all agree. Do you love it?

"tata"....

You, Lucas should call yourself the ignorant azz.



Now go sit down somewhere and stop being ignorant and disruptive in other people threads and create your own if you do not know how to act Wunderbread 👻

[Clugh]

He gone for now Ralph! Ejection seat just like b4. I see you looking for him! All the cals work the damn same. You all spend so much time with fallacy and ignorant bull **** no wonder the motors are marginal.

Get a damn life!
PLEASE...
You 2 are thirsty as hell

Thank you both very much for all your special attention.

ill show you a solid state drive coming together with no words.

I have things to do.

Hi Clown,

I have posted the performance diagrams to show you how funny these results are. And they show that I don't believe a single answer you give. The speed pilots have already done this with the Lehner motor. And if they didn't do it consciously, it is very sad what they have done. Because it shows that they have not understood how to use the motor properly.

And now to your motor, which is supposed to have such amazing performance values.
Since this is the stator of an electric motor, if you reduce the stator tooth width from 5 mm to 3 mm, it affects the magnetic force through the following effects:
1. Reduction of the magnetic cross section
The magnetic flux density  is defined as:

where  is the magnetic flux and  is the cross section of the tooth surface.
If you reduce the width of the teeth from 5 mm to 3 mm, the cross section of the magnetic path decreases by 40%. This means that the flux per area increases, which can lead to saturation of the iron.
2. Increased magnetic saturation
Iron has a limited capacity to conduct magnetic flux.
• With 5 mm wide teeth, the iron can conduct the magnetic flux well.
• With 3 mm wide teeth, the same flux has to pass through a smaller area, which causes the iron to saturate more quickly.
• In saturation, the magnetic resistance increases sharply, which means that the effective magnetic flux through the motor decreases.
3. Effect on the magnetic force
The magnetic attraction force is proportional to the square root of the flux density and directly affects the torque of the motor:

As the narrowing of the teeth increases the magnetic resistance and the flux decreases, the resulting torque of the motor also decreases.

Quantitative estimation
• If the magnetic resistance increases by about 40-50% due to the narrower teeth, the magnetic flux density could decrease by about 20-30% as a first approximation (depending on the permeability of the iron and saturation effects).
• Since the magnetic force is proportional to , the resulting magnetic attraction force (and thus the torque) could decrease by about 40-50%.

Conclusion

Reducing the stator tooth width from 5mm to 3mm significantly reduces the magnetic force, probably by 40-50% depending on how much the iron goes into saturation. This can significantly reduce the performance of the motor, especially the maximum available torque.

Show us how you came to this conclusion?

I measured the stator, especially the thickness of the stator teeth. They are only 2.8 mm wide, the Lehner is 5 mm. This leads to a 40-50% lower torque output. The reason:
physik neverly


So explain:

Happy Amps Christian

[Clugh]

Poor Dentist
I know you miserable. Look at how stupid he is. When any hobbyist can put our constants in calculator and compare the motors DIRECTLY


All bs! Here's my engine in the same calculator and it does this at 148 amperes not 1580 😁. the Eta of my motor is 3% higher it is also more power dense and he talks about it and not his falsely generated plot at 997 C*. Thats diversion for you.

But anyway you read his general a basic understanding of it but here are the results. In HEAD TO HEAD comparisons and calculator like his favorite here. His motor is the heaviest of the three and had the lowest efficiency and power density despite all its "superior" science that sound like hot trash on the castle inverter as everyone has heard in the REAL video of operation.

Efficiency governs power/weight ratio

Higher efficiency does not only mean that the motor makes better use of the batteries' power, it also means the motor is able to handle a higher power input before hitting its maximum temperature mark.

An example

Say the motor has an efficiency

η

= 0.900 and it can handle 5.0kW input. That means it can get rid off (1 - 0.9 ) × 5kW = 500watt excess heat. Now, by cramming in thicker wire (and/or using better stator-iron, segmented magnets), efficiency increases to 0.933. The motor's ability to loose those 500watt has not changed (by radiation, convection and conduction). This means the motor now can handle 7.5kW before it hits the 500watt (0.066 × 7.5kW) losses mark.

So, going from 90 to 93.3% efficiency gives an increase in power of 50%, factor 1.5

That's why efficiency plays such an important role, in any motor design: efficiency governs maximum power. All of this assuming the iron will not saturate. And the motors weight has increased (numberss and examples in Ralph's post #3 below).

A rather extreme example, just for calculation's sake/fun: going from 80% to 90% efficiency would increase the input power the motor can handle by a factor two (a.k.a. 2)

Going from 90 to 95% efficiency would increase power again by factor 2

General case

Going from efficiency η

old

to efficiency η

new

would give an increase in maximum power motor can handle by factor N

N = (1 - ηold) / (1 - ηnew)

Copper as thick as possible for ...

• higher efficiency
• more power
• lower rpm drop under load
• lower losses
• lower temperature
• at the cost of less cooling

The same person that just posted all the other things also post this almost everywhere he goes but he forgets it when it is his engine that is 3% lower in efficiency

[Clugh]

Also it doesn't matter much if its mismatched to the wrong drive like the noise box you really hear with your ears. Can I make that up? You talking about my engine you follow from forum to forum since 2016 when it hit trying to analyze it from the PC photos and not diagnostics like a REAL SCOPE of a real engineer that operates at 148 amps for a plot claiming 997 c. and 1580 amperes out of an average 41mm motor

What joke... 44kw that's hilarious . And no surprise an amateur poster who has no degree in electronics post it looking for attention... 997.2C* operational temps.

My numbers are generated under 100C at 148 amps when the saturation for the iron is nearly 1000 amperes

At your 997.c* claim the Aluminum and copper would melt and Im the clown.

No videos no logs will ever be seen in the false operation. The Align is a real thing and quiet as a fan. Off the shelf makes 5.5Kw over 5 sec. so its a great option for rewinding which the nerdy twerp does not do very well with his soft hands.

You still haven't heard what heat race the 41 series Lehner has won in any country. What record has it set?

No explanations about the ridiculous 44kW plot that so far from reality everyone is laughing at it. Do you think a hobbyist believe it or that an Align can really handle 148 amperes at 5.5 Kw?

What it can already do off a shelf!!!

Boy are you stupid! because AT THE INVERTER your engine clearly has less torque than Ralphs that's the only reason he can turn the same prop for less amperage.

You can post fallacy but not a single piece data or plot showing you are any better than either engine because you are not. Thats why you troll us and our pilots who never purchase your wunderbread.

Check the view counts. Nobody reads your silly threads so you stay in ours to be seen injecting crayon prints because u cannot operate CAD apparently.

You 41 hasn't won a single heat race for fe boating much less set a record anywhere. No body is impressed with slow poor turning 2 meter boats running 50 mph.

+3% is the Align which could definitely achieve that marginal performance seen in the videos

TATA...

[Clugh]

The truth is the scorpion could also move the boat just as POORLY!!!! The truth is we both sell motors almost daily and the idiot with his wunder motor that can operate at 997C* and 1580 amperes does not.


Hubert

[Clugh]

He can post all the epithet he wants but he cant stop my winding program or better efficiency no matter how hard he tries. Less and less COTS motors like his are needed and he is mad about that.

Just jealous of a higher peak efficiency and quieter hand wound machine out of America....proven empirically under 100C at the APPLICATIVE LOAD POINT of 148 amperes and all your calculators.

No one knows me.....but it cost me and my boat that will run better and is lighter with it 4oo euros less. My battery last longer too. U also get the benefit of one less German egg head a hole to deal with so would u care? As an American I'm personally extremely happy and gratified I didn't have to deal with an insane individual with his superior intellect and dumb **** for MORE money.

The F3A Pilots have caught on.....

Hugh

Brenner Sharp gave me your e-mail and said you could repair some Contra drive motors for me. I have 3 that are not rotating smoothly (indexing) or sometimes lock up when turning by hand. I can ship them to you and if you would look at them and tell me what is wrong with each and the cost of repair for each, I would really appreciate it.

Thanks,
Bill G.

[Clugh]

You know disruptive poster on social media wont answer where he can mount a 997C* electric motor in a carbon fiber plane constructed with epoxy that can only withstand 180C????

A disruptive poster will never offer you the 1580 ampere inverter he runs it with

A sine is still a sine and a trap is still a trap and he doesn't know the difference so the disruptive poster is mad at me because I corrected him in front of you. He desperately needs you to believe he is the smartest person in every room.

but will post a 997C plot before thinking about the practicality of it or the fact the real eta has already been posted off the manufactures dyne meter.

he is too smart for his "owen" good

[Clugh]

You are the one that has a heaviest moments of inertial and highest starting surges and brake chop. With your heavy rotor magnets that don't match the pole pitch. the segmentation is a band aid really because we can hear the open slot are still noisy as hell. the lItz wire doesn't fill better than a hairpin design to fit the slot perfect Like ISCAD. If the rotor idealized things why does it sound like trash and needs more timing to run on the castle?

The heavy bel + electrical noise that he can hear himself but OPENLY avoids in this conversation!!!.

Your have a heavy motor and heavy rotor to start and stop. I don't care for it at all because it only results in 93.3 %

I am ALWAYS welcomed to my own professional opinions based on the data u don't offer real data any in discussion just epithet!

Good thing Andreas reports the honest efficiency about it mr. 997C @ 1580 amperes

A Hilarious meltdown!

[Clugh]

And then finally what about the personal emails where you propose to redo the bell to a traditional 14 pole and use flat aluminum windings not litz?

See you forget all you say but i have it all filed because I know you are a back biter

You are in the process of looking for improvements as we speak, why would you need me to post all the redesign proposals I've been receiving for years from you into an open forum?

I've told you my thoughts about it to your face in private email the same way as here. You are a total jack ass in front of the forum because this thread is hardly about your motor. U inject it here.

Everyone's personal motor thread doesn't need to funnel down to advertisement for Lehner! It will continually be rejected here....


Hubert

[Clugh]

why you not posting on RC network anyway Christian???


Sie wissen, dass ich weiß, dass Sie versuchen, die Sperren und Verbote zu umgehen, von denen Sie wissen, dass sie unmittelbar bevorstehen.



They are going to eat well when its starts..... Their anchor reporter will certainly report his 997*C findings!!!

Ich hoffe, Gerd und Thomas lassen sie feiern, da Sie über sie und ihre Kinder genauso reden, wie Sie in einem offenen Forum über die Debatte „Ich gegen Rogerian“ reden. Wir sind alle Esel und Clowns und POCBOYS … aber was sie wirklich brauchen, ist, Sie mit Ihrem Irrtum, Ihrem rassistischen Schimpfwort und der durchschnittlichen motorischen Leistung, die Sie ihnen vor die Nase halten, aus der Stadt zu jagen.



Got ya again....

I have the GanFets in and YOU Christian Lucas are being very disruptive to what i am trying to show the hobbyist here. It's getting old at this point. Everything i report is real the data etc. You know that Stop acting ignorant man. It is becoming a real distraction to what i'd like to show. You have to agree that 997 degrees Celsius at 1580 amperes is not anything a single rc modeler here is going to engage or believe in.

Irrtümer und Beinamen werden nicht gewinnen.

Ich werde die Laufwerke, die ich für das Forum baue, weiterhin betreiben. Das wird diese Tatsache nur noch deutlicher machen. Ich schätze, Sie bleiben hier und tippen einfach, und Sie werden beim nächsten Kopf-an-Kopf-Rennen wieder verlieren.


Hubert

[Clugh]

How will fallacy and ignorance possibly win? I never saw the development tools you used to build a BLDC Drive I asked you about Christian???

Got ya again....

Hubert

[Clugh]

Es ist wirklich eine Schande für die Elektrotechnik, wenn jemand bei 1,5 kA vorsichtig ist, obwohl das Gerät nicht einmal die Komponenten hat, um der vorgeschlagenen Betriebsumgebung standzuhalten. Das ist der Unterschied zwischen der praktischen Seite eines Empirikers und der eines reinen Theoretikers, der übermäßig aufgeregt ist, aber nicht alles durchdenkt. Er ist völlig verrückt und mit seinem ignoranten Verhalten furchtbar verstörend. Daran besteht kein Zweifel. Seine Argumente sind verrückt, also kann ich es nicht wirklich sagen, aber er scheint die Anwendungslastpunkte der meisten RC-Modellmotoren und die dem Verbraucher zum Antrieb der Motoren zur Verfügung stehende Ausrüstung nicht sehr gut zu verstehen. Wenn Sie ihn danach fragen, erhalten Sie keine Antwort, sondern stattdessen Beschimpfungen.

[Clugh]

It's really a disgrace to real engineering when someone is asking consumers to look out to1.5kA load point when the proposed device that supposedly does it doesn't even have the raw components to withstand the proposed operating environment. That's the difference between the practical side of an empiricist and that of a pure theorist who gets overly excited but doesn't think everything through. He's completely insane and terribly disturbing with his ignorant behavior. There's no doubt about it. His arguments are fallacy filled not fact based so I can't really say but he doesn't seem to have a very good understanding of the application load points of most RC model motors and the equipment available to the consumer to drive the motors. If you ask him about it you won't get an answer, but verbal abuse instead.

This is also really poor reporting to any perspective consumer who will never see those false load points. The hall sense still wont save a rotor magnet and is still not active at wot. Ralphs motor still does not generate a sinus and will run great with a castle 6 step inverter as will many other motors Including Lehner 2 pole in runners. With which it holds the LATEST record now.

You see and hear clearly which motor between the COTS Lehner 41 and my Hanslemann asymmetrically wound HK 4025 commutates better with the castle because I showed you.

Itz easy to talk like you do...


Hubert

[Clugh]

To me its tragic because after 360 degrees of ignorance on an open forum nothing has changed but the loss of professional respect and valuable time. My original statement that A pure BLDC system with a motor that produces a true trap bemf will be ideal over a sinus system is still the case. A typical mixed tooth width stator will create this more Ideal TRAP waveform as will a hybrid winding. It is lab, mathematically, and analytically proven fact they will also attenuate the two pole harmonic that creates a sinus which takes a tremendous amount of stress off the 10 or 14 pole rotor and PM. It doesn't pay dividends for two grown men to go on like that so I don't know why you choose to continue and cannot just stick to the facts, the data, and the truth.

[Clugh]

Here is the floating zero point space vector control drive schematic that exceeds the sophistication and capability of a YGE 320 quite easily. It isn't American the Mitochondrik IC is manufactured by my friend Pavel from Estonia . Don't believe the nationalist nonsense and all the international hype. People are paranoid. There's no conspiracy against Germany I love Benz and Porsche 😁 but I guess they see now that this is the most sophisticated OPEN SOURCE motor agnostic FOC svc commutation complete with UAVCAN right? It can learn the prop and set the inverters commutations optimally to it. It requires a wind tunnel to set it up correctly. Do you have one??? Along with your Drive design tools you haven't shown me yet? Pavel and I have already amended clamped gate driver circuitry for the GaNFETechnology. Pavel is young and extremely bright and the commutation algorithmic brain in my GaNFET SVC FOC drive.

Brexxit!
