Alternative motor windings and drive schemes

[Clugh]

You can send your highest pitched croco blades in Germany here for 12000 rpm and I'll turn them direct drive and geared. What do you want to do but remain silent and learn here?

Do you really want some of this "American Supermotor" Dr Okon? Because you can get it as soon as you produce some data!
Neumotors is already in another Class!!!

I also own the cuts with full rights to build and develop the estranged and jaded Christian's 24 slot super engine and the 125mm cut he brags about all the time. Fully permissioned by him.....Did he tell you that?

So you know what to do....right?

[Clugh]

Do you wanna play with my 24 slot AMERICAN super engines? How? you cannot master the 12 slot yet.

Id be happy any day youd like to compare but first youll need data!!!

Slick-33 weist den niedrigsten Reibungskoeffizienten auf, den wir je erreicht haben – lediglich 0,0467 % CoF gemäß ASTM D2266-Standard.

Stellen Sie sicher, dass Sie und der Motorenchef in Bayern überhaupt wissen, wie hoch der Reibungskoeffizient des Schmiermittels in Ihren NMBs ist oder was auch immer für ein Unsinn er verwendet, Dr. ... Sie beide haben keinen Schimmer, was wir hier verwenden, es sei denn, ich sage es Ihnen! Oder sogar, was Ihre eigenen Lager verwenden ...

Kopieren Sie es!

Es ist einfach, HYPE!!! zu tippen.

Danke

And you are still here in the "psychopaths" class err day.....

Hallo Dr. Okon, ich sehe, wie Sie auf der Suche nach mehr im Forum herumstöbern. Wir haben die Hybriddaten, die Sie angeblich haben, noch nicht gesehen. Dasselbe Geschwätz in die Threads anderer Personen einzubetten, funktioniert nicht. Ich kann sie alle lesen. Ich bin auf dem Laufenden.

Wo ist der Datenzuhälter?

The Russian Cyclon .40 is 3.2 kw at 31,000 rpm it weighs 310 grams. A Dubb Jett 40 is 340 grams. The p600 depending on the wind will be between 315 and 340 grams all day and the lil bomb can peak around 5kW at 30,000 so that is what the little power turd can do... Its extremely potent and scary on the 7X10 direct drive even at 8 s lipo. .I'm not running THAT in my kitchen. I tapped the throttle on the Futaba 10PX a few times and said oh hell no..... Its also quite loud.

I cant find the .40 pylon prop i just purchased to test. I have so much junk around here I lose things right in my face....When I find it and finish setting up a power supply that is not my drag cells i will run it on the various scrap iron around here.

36 true EV cells. They have plenty of capacity and I wont have to worry about solder tabs etc. These are real cells! for the reactionary torque cradle that's only limited by the motors own RPM which will be optically tach' ed.

[Clugh]

The little 600 is right on pace with the best pylon engines. If you think about it its a little stronger. The last Metketmeijer Brothers .40 benched @ 2.5Kw at 30,000 rpm.

[Clugh]

If I build a dedicated engine for the purpose the bearings would be turbine grade ceramics so about 300 dollars for a pair. They will never be replaced! and can run well over 100,000 rpm with load rating about 3 or 4 times a hobby grade radial bearing.

An NMB is not an electric motor quality bearing. That's fact. Its a general purpose bearing that works good enough for the average hobbyist. People looking for custom wound engines with 5 to 10 thousand dollar planes are not the average hobbyist though.
That would be a goal.

We have a different design philosophy. You want to perform yearly maintenance which you will so severely underpowered but if its possible Id like to not ever see engine I built again! To me that's a worthy goal One may never achieve but that's certainly what a customer would prefer. Endless running.

But im not greedy like some people....

I also wonder if legendary nitromethane engine builders like Henry Nelson or Dubb Jett said. "oh well that's good enough"

[Clugh]

Now Im off to wind 2 more 650 growlers for 2 more TDR's to control the helifreaks.. See the horrible "smearing the American does"???? Your friend in Bayern was also wrong about the ceramic bearings he has no clue about the special lubricant we use unless I told ya, which is the slickest in the world.

You all are so high end with the pure insulator UHU endfest and 5 dolla NBM's. How could we ever compete...?

You should ask Lucas what the coefficient of friction is on the grease his steel bearings use or that packed in a NMB or maybe even your 7455 bearings from CHINA! Louis asked you about.

They are surely trash....if its not Swiss German or Japanese made I don't want it in my motor PERIOD! You can install and run the garbage into the ground. I'm absolutely elated about that....

Were still using Boron nitride here in America

Dr. Okon, ich erkenne auch die Heuchelei darin, dass Sie diesem neuen Wickler, der seinen Stator ziemlich gut gewickelt hat, sagen, Sie trauen der Wicklung nicht, weil sie sich lösen kann, obwohl Sie derzeit nichts an Ihren Motoren verwenden, trotz all dem Gerede über Aluminiumoxid. Als der Wickler Sie fragte, womit er seine Drähte befestigen soll, ignorierten Sie ihn, um sich nicht ins Fettnäpfchen zu treten.

What a hypocrisy! His winding is as safe as yours which also uses nothing to secure your wires.

Hi m reading more speed BTW

"The new Typhoon Ultra max was ready in time for the GSC. Thanks to Marcus for laminating.
Let's see how it goes at the weekend.
Drive Scorpion HK5050 (Powercroco) with 16S SLS Speed cells and YGE ESC prototype."

~Thomas Moldtmann~

The response

"The load should weigh about 6kg, so it needs at least 25kW, good luck!
Where is the CSD reported?"

~Audio smith~

And he's right since scorpion only reports 11kw for a 5040 so it will be grossly underpowered if it need 25 kW!!! its at least 10 short. no one will average 600 kmh with it because no one ever has....

[Clugh]

Hallo, ich sehe, du bist noch da. Was hast du vor? Deine Freunde warten sicher auf eine würdige Erwiderung ...

[Clugh]

Ohmical Dr? Ohms law is just one law in electronics. There are many others laws and theorems concerning various circuits in electronics.

Try Faraday's



Get some sleep buddy....

[Clugh]

Itz funny . The 4225 was 1 milli the align was 5 milli but the ETA was 3% points higher with 5 times your resistance. and a much better Io

[Clugh]

Ive explained umpteen times the motors move with AC not DC. It is not a brushed DC motor.

[Clugh]

Its funny he says an amp in idle current is nothing but 1 amp time 50 volts is 50 watts but 2 amps by 50 volts is 100 watts. Ask the Dr if the 100 watt soldering iron is hotter than a 50 watt....

The other point is the mean current deviation of the strands so some of the wires are significantly hotter than the others. None of that's good for the highest efficiency which is almost everything in an electric motor.

[Clugh]

As you've been told before the AC resistance can be 10 times the dc with parallel strands and while you think a few point in idle current is nothing you never explained to the readers that despite the low dc resistance all the paralleling gave you and the copper fill the best the thing did was and eta of 83%

What about that fact ???

17% of real loss???? Not 1 of the single wire parallel wye's wound in a motor this size would generate an eta that low.

Learn the difference between DC and AC resistance Doc.

And that stall current doesn't even come into play at the frequencies the motor runs at. I told you that years ago . Since Dr Gerling is a cited refrence on the Phd. You should ask him another Phd. about itz validity.

Low dc resistance is not stopping them from burning up, and it has zero to do with noise killing the magnets because there is no frequency at stall!!!!! U gotta have magnets for any of the bs to work.... All frequency induced losses are not present there but they sure are when you are running at WOT!!!

You are very confused about how this works and that may be why your results never match anyone elses in the world on the subject matter.

The big motor doesn't make any torque either based on MHZ specifications of it. There are lighter motors that make much more.


Danke,
Hubert

Let me address the most obvious first.

Firstly 'Ohmical' is not really a word but the ohm law refers to DC were talking about AC so Impedance is what we are looking at here. Learn the difference DOCTA.

In addition to resistance as seen in DC circuits, impedance in AC circuits includes the effects of the induction of voltages in conductors by the magnetic fields (inductance), and the electrostatic storage of charge induced by voltages between conductors (capacitance). The impedance caused by these two effects is collectively referred to as reactance and forms the imaginary part of complex impedance whereas resistance forms the real part.

So you see youre already in trouble with your thinking.

The term impedance was coined by Oliver Heaviside in July 1886. Heaviside recognised that the "resistance operator" (impedance) in his operational calculus was a complex number. In 1887 he showed that there was an AC equivalent to Ohm's law

Hi Dr Okon. I see you reading here. Do you remember this motor in the attachments? The pretty orthocylic lay with bifilar in 2 x 1.18 mm? It was 4 part motors all wire in parallel so each motor terminal was 8 strands of conductors in UVW.
Look at what you said here.

you can wind and terminate them step by step and measure the single motors on 7455stator.

in this special case I found for the idle currents:

1 motor: 11,35A (2 untwisted parallel Strands)
2 motors: 11,5A (4 untwisted parallel strands)
3 motors: 11,72A (6 untwisted parallel strands)
4 motors: 12,02A (8 untwisted parallel strands)
4motors with another winding (3 x1,18mm): 12,2A (12 untwisted parallel strands)

if someone condsiders, that the ohmcial resistancy decreases to 1/4, the increase of losses by switching the motors in parallel is really low. (there are only 6% (7,5%) increase of idle current by switching the 4 motors in parallel)

if someone uses the holy formulas with these data , he can easily find out, what affects the efficiency more:
the 4 times higher stall current (400%)(500%) by decreasing the ohmical resistance to 1/4 or 1/5.
or
the increase of idle current by 6% (7,5%) !"



last but not least in real life someone has to consider, how much of the increase of 0,7A (0,9A)in idle current is a follow of the higher iron losses and ac losses in the coils and how much is the follow of the much lower ohmical resistance!"
