Alternative motor windings and drive schemes

[Clugh]

I also dont want the boys or your friends in Germany to think I'm talking to myself like you've also suggested throughout the years. I want people to see the reality.. When I talk YOU listen. Even this is a lie because you are not 1Boho that's me actually. You are Dr Okon aka Borat aka Powercroco so why you trying to fool people on our forums is beyond me.

You suck up every drop of information offered here in America.

Come on America get real...

1..I've wound the motor for him and posted photos
2.I've run the motor for him and posted videos
3.I've recorded the constants and plotted the efficiency
4 I've showed him and you all purchased wiring diagrams from the African Drs. I paid for directly from the IEEE with straight cash!!!!!

Ask yourself 1 question what has the Dr really given you tangible on the subject matter in this post:?

"The last entries I could find on this topic are from March 2023.


I could not confirm many of the theses put forward at that time, at least in my experiments with a P800 and the standard 14P rotor as well as the 10P bell, which was still in the grab box but was not transferred to series production at that time.

After all, the motor runs with such a winding - and that too (from a purely sensory point of view) very clean and quiet.

In my opinion, the advantages discussed at that time are probably - as suspected - more "academic" and not practical.
So just like with the 7-8----8-7 Gerling winding.

I had chosen 7D +(7x1.73 =4)Y with adapted wire gauges.

Would like to exchange data via PN if the worst comes to the worst."

~Dr Ralph okon~

The "Dr" still needs more ????


yet he doesn't want to exchange that data privately or openly with the American he got it from..... and then proceeds to tell them in Germany the American engineering is suspect here....

that is very logical isnt it.????? Considering alot of the Tech ive shared comes directly from Germany.

Simply a bunch or epithetic, fallacious, mumbo jumbo out the posters mouth.

Ive even given them the entire BOOK from Dr Gerlings motor mathematics over 6 years ago.

The "wurst" is here sharing with him and he has executed the winding from the diagrams I showed him.



If I left you all today what would he share with you about electric motors or inverters ??????????????????????

Now I have things to do.

Good morning America!


Hi Docta ,

250 feet of 22 awg 99% pure Ag magnet wire from America is 3,250.00. USD!!! Can you afford it and the tariffs on top on motors where 5 dolla NMB's stretch the pilots bank.?

A true bullet proof hi end 500 - 1000 ampere electric motor for a speed plane that wont break is going to cost a pilot some real cheddar

For me to set it up with a large Talega based bridge is probably going to run you over 4,000 dollars and I guarantee you that antiquated conventionally wound scorpion with no potting and 5 dollar ball bearings with a Turnigy brained yge 320 at a16 kilohertz max brake will not come anywhere close.

A true speedmaster can afford it! But it isnt like a conventionally wound P1000 hasn't already destroyed it.

I hate for people that get it the redundancy needed to reach some of us.

[Clugh]

You just don't understand state of the art SENSORLESS motor control. See if your YGE or basic hobby inverter can do it.

Get some rest!
Hubert

[Clugh]

As everyone can see the "suspect" American engineering for such a propeller drive unit is actually from Estonia which is in Northern Europe.

Nein, sie hören dir einfach nicht mehr zu. Sie sehen den Unterschied im Kupferverlust zwischen den beiden Maschinen direkt in Tests, die bereits von den besten Experten der Welt durchgeführt wurden. Bei korrekter Wicklung liegt er weit unter 1 %.

Du hast Daten zum Vergleichen, also bist du einfach nur unwissend. Wenn du es vermeidest und den von Experten geprüften Daten von Ingenieuren nicht trauen kannst …

Bist du sicher, dass du ein Arzt bist? Weil dir Logik und Wahrheit fehlen …

Schade, dass dein Scheiß so verworren ausgegangen ist.

Hier beträgt die veröffentlichte Differenz 1/4 Prozent.

Hier ist das Foto. Wo ist das Gewirr, das er in meiner Maschine hat? Es ist nicht nur ein Hybrid, sondern ein Parallelhybrid, isoliert mit Bornitrid-basiertem Epoxidharz über reinem Silberlot. Es hat einen geringeren Widerstand als der entsprechende Massivdraht.

Here's some numbers from a running test!

The P650 5Y + 9D parallel hybrid in 22awg
Kv 1072
Rm 28.3 milliohms
Io .7 amps @ 16.5 volts

Für euch Freunde, die ihr keine Idioten seid, ist es ganz einfach. Sie müssen nur einen Lügner dazu bringen, einen 1072-kV-P650 zu wickeln. Sie wollen ihn sowieso für 28,3 Milliohm und melden den Leerlaufstrom. Sie würden auch deine vorsätzliche Ignoranz erkennen, da man dir ja schon millionenfach gesagt hat, du sollst die Glockentemperatur mit einer Last testen. Vielleicht erinnern sie sich auch an deine Aussage, dass du einen Freund hast, falls du Daten brauchst. Warum hast du deine Lügen dann nicht an seine Werkbank geschnallt? Du bist nicht mal ein guter Lügner, mein Freund.

und ich habe dir bereits gesagt, dass Sebastian und die Jungs nichts getan haben. Du bist langsam, Bruder.





Hubert

[Clugh]

Und was ist deine Spezialanwendung? Feuer?




Und deshalb müssen Verlustströme und Betriebstemperaturen nicht gesenkt werden?

Ja klar, Kumpel. Du hältst die deutschen Bastler bestimmt für Idioten.

In deinem Forum gibt es drei Threads dazu. Außer dem, den ich gepostet habe, wurden in keinem einzigen Thread auch nur die geringsten Daten angeboten.

[Clugh]

An meine Kollegen in Deutschland: Dr. Okon ist witzig. Erstens verwendet ein YGE keine Blockkommutierung außer unter Volllast. Wo sind also seine Leerlaufstromberichte und seine Motorkonstanten? Dr. Okon belügt euch fast täglich, und es ist wirklich schade, wenn ihr in Deutschland seine Widersprüche und seinen Unsinn nicht durchschaut. Er ist ein echter Kerl und scheint sich überhaupt nicht darum zu kümmern, ehrlich zu euch zu sein. Das ist wirklich schade für euer Forum. Das Mindeste, was er tun könnte, wäre, euch bessere Kugellager für einen 1000-Euro-Motor anzubieten. Es ist wirklich eine widerliche Idee, euer Vertrauen und eure Ehrlichkeit in seine vermeintliche Expertise auszunutzen. Wenn ich im Forum wäre, würde ich ihn fragen, wo seine Daten sind. Ich bin sicher, ihr macht das alle jedes Mal, wenn CL etwas postet. Deshalb heißt es ja Crocoworld. Ihr hinterfragt ihn nicht annähernd mit dem gleichen Eifer..Andererseits ist es wahrscheinlich besser, sich nicht auf seinen Unsinn einzulassen, wenn Sie ihn wirklich als das erkennen, was er ist.


Danke

Americans:

If you LISTEN in the HYBRID video you will hear the whistle. I've analyzed where that occurs on a 10 pole HKIII4025 asymmetrically wound machine with the scope and a crude smartphone RTA. It's going to occur around a fundamental of around 300 - 309 hz so what you're hearing is approximately 2.7khz. The rpm associated with that fundamental frequency is where the triple harmony occurs. You can see in the video when I purposely hover around the associated rpm the AC operation is at its poorest point. The idle current amperage is highest there. You may say well that's because of the partial throttle operation which is partly true. It is higher than at WOT at almost any point, but if you lower the rpm below the point that its induces the triple frequency, being any frequencies that can be divided equally by 3, the current lowers significantly despite still being deep in partial throttle operation. 2.7 kilo is also approximately the 9th harmonic which very close to the 10th which is a multiple of the working 5th and I'm pretty sure that why the bell is ringing. I'm sure if that were prominent enough under a heavy load perhaps it might dislodge the magnets. There are ultrasonic vibrations that definitely generate enough modal energy to pull it off with a brittle adhesive. The 14 pole P600 seems to ring alot through its rpm range but in not sure if that is the transistors PWM causing that sound or something similar to this. I think its this because 8khz is obviously a much higher pitched tone than what you are hearing. Nevertheless these frequencies in the ultrasonic can kill a steel bearing through the motor shaft. Thats where the EMI shielding and non conductive balls come into play they are inherently electrically insulated. They are CERAMICS. This is also how why you'd implement something like low pass filtering it will only pass frequencies lower than its set point at a descending slope. The sharper the slope the faster and more abruptly it attenuates those unwanted frequencies that emanate those triplen harmonics . They rob power as you can see in the video. It is clear proof for me that the quieter commutating machine that vibrates less is going to be more efficient.

Vibration noise free running certainly does improve efficiency if you compare two motors with the same Kv and Rm because it lowers the idle and load currents compared to the conventional machine.

I feel very safe to say this.


BTW I could look at the RPM when I ran the 4025 because I built and coded and optical tach to watch the speed and also record and interpret the rpm as frequency but understand this frequency is different than the emf fundamental frequency

Thank you,
Hubert

[Clugh]

You can see and HEAR in this video of the asymmetrically wound HKIII 4025 that when the motor gets around 60 hertz rotational frequency and 3660 rpm the same phenomena occurs. These motors and at least my 6 step inverters do not like frequencies that can be equally divided by 3

This is pretty Empirical. I dont need a PN for open forum discussion with Okon.

[Clugh]

If this is what the windings brings and you believe 1000s of Electrical Engineers over 1 retired Army Medic that winds hobby motors for his friends tell me how is it HIS application has no use for its advantages?

I can not think of single e traction application that would not benefit greatly from these things. Can You? You can see clearly the direction the PM and rotor performance is going. . If his application runs into desynchronization and Demag which it does how in the hell does he think he cant benefit from it if he has a lick of common sense about electronics? His current motor winding yields an eta of 68% at full power.

I'm sorry that is really ignorant bs to say from him. His application has no use for it....

Really?

What does dual layer parallel wye winding bring a speed plane motor that this wouldn't better and his motors are currently failing?

[Clugh]

The machines with the lower total harmonic distortion, which is what you are hearing in the videos have a better power factor and almost always a better efficiency.

Die Maschine mit der geringeren Gesamtklirrfaktor, die Sie hören, hat einen besseren Leistungsfaktor und fast immer eine bessere Effizienz.

Die Maschine mit der geringeren harmonischen Verzerrung, die Sie hören, hat einen besseren Leistungsfaktor und fast immer einen höheren Wirkungsgrad. Dr. Okon ist sich nicht darüber im Klaren, dass er keine Ahnung von Elektronik hat. Wer ihm zuhört, ohne intelligente Fragen zu stellen, wird Schwierigkeiten haben, das Thema zu verstehen. Er verfügt weder über Daten noch über Videos, die seine Ideen stützen.

The thread is going to fall to the bottom just like the others Ralph. It is pure nonsense....

Sie können es nicht mehr gebrauchen, da Sie in Ihrem eigenen Forum diesbezüglich ignoriert wurden, aber Sie haben jetzt schon zweimal versucht, es aufzuwickeln und stellen immer noch Fragen dazu. Wenn die Version von Dr. Gerling nicht funktioniert hat, warum sind Sie dann wieder hier, wickeln es erneut auf und fragen nach einem anderen Hybrid?

Oops caught ya again.....

Thanks for your time and patience,
Hubert

[Clugh]

I realize you dont know anything about electronics Dr Okon from your post..

THD is a measure of that additional signal content not present in the input signal.

When the main performance criterion is the "purity" of the original sine wave (in other words, the contribution of the original frequency with respect to its harmonics), the measurement is most commonly defined as the ratio of the RMS amplitude of a set of higher harmonic frequencies to the RMS amplitude of the first harmonic, or fundamental frequency^{1][2][5][6][7][8][9][10]}



where V_n is the RMS value of the nth harmonic voltage, and V₁ is the RMS value of the fundamental component.

For many standard signals, the above criterion may be calculated analytically in a closed form.^[1] For example, a pure square wave has THD_F equal to


The sawtooth signal possesses


For the rectangular pulse train with the duty cycle μ (called sometimes the cyclic ratio), the THD_F has the form



and logically, reaches the minimum (≈0.483) when the signal becomes symmetrical μ = 0.5, i.e. the pure square wave.^[1] Appropriate filtering of these signals may drastically reduce the resulting THD. For instance, the pure square wave filtered by the Butterworth low-pass filter of the second order (with the cutoff frequency set equal to the fundamental frequency) has THD_F of 5.3%, while the same signal filtered by the fourth-order filter has THD_F of 0.6%.^[1] However, analytic computation of the THD_F for complicated waveforms and filters often represents a difficult task, and the resulting expressions may be quite laborious to obtain. For example, the closed-form expression for the THD_F of the sawtooth wave filtered by the first-order Butterworth low-pass filter is simply THDF=π23−πcoth⁡π≈0.370=37.0%,

Low pass filtering.....APD and BL HELI32 can do it with betaflight....that old ass YGE Powercroco promotes to his friends and customers cannot

I know you dont understand a thing I am showing you. I can tell you in my own words or even post directly fundamentals of electronics and you still cannot get it. "DR OKON" .\O/



I know you dont know a thing about 16 and 32 bit DSP based motor control IC's or low pass filtering using a majority function that monitors the erpm (frequency).



I'm off to wind for the F3A and HELIFREAK boys no more time to CLOWN around. with you. You showing me you don't know nothing.

Good luck from the USA with more input and information about the subject matter than you can wrap your tunnel vison around apparently. Because the only thing that works according to you is a conventional and clearly outdated wye winding where 300% of the phase currents sit in the pigtails versus being dissipated through a 3 phase delta machine with higher current ampacity. You're brilliant about the subject matter for sure.

Please burn down as many of your friends 5000 dollar planes and electronics as you would like. The 5 dolla bearings are a real smooth touch. For such an aircraft. You are here everyday for all these ideas and things that "DO NOT WORK"!

LOL!

And be sure Americans and those interested to understand before he lies to you. Please understand that my wind is equivalent to this circuit in parallel. Dont let him confuse you or lie with the diagram above in post number 4116 that says a "parallel" phase connection between the outer delta and inner wye is unpreferred. Thats is not what I'm showing you. What is have is the preferred outer wye inner delta serially connected hybrid like this diagram on each stator half and the motor terminals (UVW) of each motor is paralleled together. That halves the overall circuit dc resistance and the 2 pole harmonic (low order and non zero) is attenuated by the serial interconnections between the wye and deltas on each stator half which is going to create a purer BLDC signature that takes alot of stress off the rotor and pm. The 2 pole is a sinusoid. if you remove it and boost the 5th and 7th harmonics of a 10 or 14 pole pseudo sinus BLDC some form of the purer Trap or Triangle is all that could be left. Its more torque, less torque ripple there and thus less mechanical vibration and noise there especially teamed with a six step inverter. The power factor and efficiency is going to improve. Ralph can run his mouth until he is blue like papa smurf in the face. He hasn't a Clugh what he is talking about.

The IEEE Phd's have it all figured out. Trust them. Maybe they should have explained it to you this way

See how my semi magnetic low loss carbonyl/PLA slot wedges will fit the 50 series Scorpion Americans?

He is jealous of US

That's all this nonsense is about. Ill tell you with him as a live witness.... Dr Okon is not brighter than me when it comes to electronics, computer science and manufacturing . I been passionate about it since about 4 years old. Thats 50 years plus the degrees diplomas, and certifications in all things relevant. The Dr, who was studying medicine, biology and anatomy, and the title he carries means zero to me. This is not at all his lane. I was immersed in audio and electronics technology while he was studying the human body.. He should keep it real with you all.
.
I teach him everyday anyway even though he is supposed to be smarter than me. Can you tell he's smarter about this by his post and lack of data? He's never given you 3 solid points to support any ideas he's had about any of this.

Despite all his pm's and crying about it. He cant touch the American ..... he has zero creativity and no vision. All he can see is his wye wound 10 pole scorpion knocker. He is brighter than the entire IEEE and electronics are not even his discipline.

As a hobby machinist the German hobbyist could not even tell you how to check a tail stock for proper alignment on his lathe.

Now he can go look it up....online
