    In the USA, copper-coated aluminum is also soldered like normal copper. No crimp connection, unless the Airtite connection is comparable. Dr. Okon does not have the right tool for such a crimp connection. Besides, I thought he was soldering. Why are we thinking about crimping now? The Grand Wazoo won't be able to get a single recorded engine constant out of the pink pile of nonsense anyway.

    No one will cry except the late eight in Jonestowne

    We are the dog catchers.

    Das wird nicht passieren, also brauchen Sie sich keine Sorgen zu machen.Click image for larger version  Name:	image.png Views:	0 Size:	2.2 KB ID:	433249



    Keine Sorge, der Motor meines Woozoo.Ralph läuft nicht besser als dein Mund. 68 % sind in den USA sicher nicht die Nummer eins... In Amerika brauchen wir keine 380 Ampere in 60 Sekunden plus Feuer, um schnell zu fliegen. Wir schaffen das mit 60 Ampere und einem 16s-LiPo-Akku und bleiben unter 100 °C*. Viel Spaß mit dem Maus-Laufwerk. Die Luft aus deinem Party-Instrument stinkt wirklich.

    Read it again:
    A standard 4638 289 kV neu motor on 16s Lipo 2500 mAh 80/100C cells and the APD HV 20S drive on a GM 10x23 can deliver 28 pounds of thrust at a pitch speed of 509 km/h at only 60 amps. The ETA there is 90.4% the motor temp level at 100C.

    The motor only needs 3.295 Kw consumption to make it happen at the prop with 14,500 rpm.​​



    Danke,

    You seem to not realize the recorded motor constants like idle current are directly affected by the inverters relationship to the machine. A motors efficiency without the inverter is zero because it doesn't do anything without it.

    "Hubert's" efficiency in America is not what sets the planes on fire in Germany!!! You need to have larger concerns...

Every plot carries the currents out to beyond the applicable points but I ensured the max eta is delivered is at the applicative current for which it was designed. 157 amperes at 10s lipo in a boat. Secondly I don't know who told you the signal for a single layer was "cleaner" . What you were told its that it is more suitable to work with a BLDC inverter which is six step. It is also fact that it generates more torque. U ask a question and cannot accept the answer when it does not suit your incorrect assumption or bs like your passage about 500 ampere on a plot. You do not know anything about boat props or the load the exert on a motor so don't talk about what you do not know. All you have to do with the plot is draw a vertical line at x=157 amperes and you see where the motor truly operates in the model.

    Click image for larger version  Name:	image.png Views:	0 Size:	57.0 KB ID:	433222The single layer produces higher amplitudes in all harmonics. The working ones and the subharmonics that rob the magnets of power. The higher amplitudes in working mean that is indeed has a higher winding factor but without attenuation of the subharmonic it eats up the rotor magnets faster so it will lose sync earlier. You don't need thicker magnets all you need is what you have been told umpteen times so Its really isn't our fault why you cant or wont implement a slot wedge, hybrid winding, or dual 3 phase commissioning to alleviate the issues before you all contemplate all this other bs. Originally the motor Fuhrer's called for a winding as pure as possible but since they have problem routing that pure winding they do not want it anymore. I sized it properly set the Kv properly and do not ask more out of the motor than it can deliver that's why the props were carefully selected from a very large field. You hardly have our options with 10-15 measly speed propellors for airplanes available.

    I also suggested SmCO magnets some time ago which have to be thicker for the same magnetic energy anyway and they did not want that either.

    Let him tell it there are no solution for any of these issues according to Dr Okon.

    The truth is there are several and they all work. So keep it real with yourselves and find you an e motor tuner that can simply deliver the necessary tech!

    Hallo Dr., ich sehe, Sie versuchen, das veraltete Leistungsgewicht des Motors durch die Verwendung von reinem Aluminiumdraht zu verbessern. Haha, wissen Sie, dass Sie dadurch Ihren Gleichstrom verlieren? Ich würde kupferummanteltes Aluminium wie dieses verwenden. So können Sie Gewicht sparen, ohne den Gleichstromwiderstand zu erhöhen, der Ihrer Meinung nach die Leistung bestimmt. Ich brauche keine zusätzliche Beschichtung, da das den Gewichtsvorteil nur zunichtemachen würde. Das ist dumm und widersinnig. Wenn eine Beschichtung oder Farbe die Leistung nicht verbessert, erhöht sie nur das Gewicht der Drohne. Das ist doch Blödsinn!​


    PS: Ich kann die 20 Windungen des ca. 13,5 AWG starken Drahtes tatsächlich problemlos unterbringen. Das entspricht über 40 % mehr Nutfüllung. Natürlich wird der neue Kern eine kleinere Nut haben!
    .
    Und Sie nutzen auch christliche Ideen, um Ihren Motor zu verbessern. Sie sehen also, dass Sie diejenigen sind, die miteinander verbunden sind. Wir warten immer noch darauf, den 20-poligen 12-Nut-Motor laufen zu sehen.


    ​Wir warten außerdem immer noch auf vollständige Fotos des Hybriden, den Sie angeblich verletzt und von dem Sie Daten gesammelt haben. Wo sind diese Daten, Dr. Ich werde noch jahrelang fragen

    Das ist ein Hinweis darauf, wer hier ist, Dr. Okon. Ich bin alles andere als langsam, Bruder. Ich weiß genau, auf welcher Website diese Regler angesehen wurden, Dr. Okon, und wer sie dorthin verlinkt hat …Ihr Freund hat die Website meines Freundes Fabrizio Russo besucht, auf der dieser Wechselrichter verkauft wird. Sieht so aus, als wäre Stefan hier, Ralph …

    Die präzisionsgeschliffene Unterlegscheibe auf der linken Seite beträgt 500 µm. Auf der rechten Seite befindet sich das eingestanzte BS, das mit vielen Motoren geliefert wird. Können Sie sehen, dass es schief ist? Die diesbezügliche Stempelung ist nicht richtig und exakt. Mit einer Erdungsscheibe erfolgt die Abstufung in 500-um-Schritten. Sie können auf seinen Arsch hören, aber ich weiß, wovon ich rede.

    Danke,
    Hubert

    Ich sehe alle neuen Mitglieder, die hier im letzten Monat neu hinzugekommen sind. Sie haben keine Standorte aufgelistet, daher weiß ich bereits, dass sie hauptsächlich aus dem Osten kommen. Fast jedes legitime Mitglied gibt seinen Standort an, daher weiß ich es. Amerika hat immer noch einen Platz in der Technologie, man muss nur die richtigen Amerikaner ansprechen.

    The 4020 scorpion only has one bearing supported by the frame the other bearing is expected to stay in place just using the loosely dimpled tabbed stator It cant make much mechanical or electrical sense if the stator suffers deformation during operation. The bearing right on the iron cant be ideal to shield it from triplen currents on the shaft. That will only facilitate faster ball degradation due to ultrasonic frequencies. Ultrasonic cleaning and cavitation takes place around 48 Khz.

    I don't think "Dr Okon" is aware of the physical science involved.....

    I'm not a " Dr" . so I dunno.......

    And tell Ralph not to use a press to install your bearings. I know he does. That can damage them immediately after installation! Preheat the frame to about 100°C and freeze the bearings. After removing them, wipe any frost off the outer race before installing the bearings. They'll pop in easily, and you should feel them touch down.

    Danke,
    Hubert

    Wenn er so schlau wäre, hätte er den Freilaufstatus des Rotors ohne eingebauten Kern überprüft.

    Its ashamed that you do not realize there are better motors that are constructed with more than two bearings which is inadequate for motor like the 5050 in the first place that's why you are having stator/bell strikes. I have seen them Dr. You cant deny it nor can you produce a free rolling video on the YOU TUBE like I did with a ceramic hybrid properly lubricated. Try it with the NMB!

    Learn this!!! Most of the shims that come in motors are cheap pressed tin. They are not exacting in ID OD or thickness, and often they overhang the bearings inner race and that produces drag against the bearing shield if you remove all the axial play. To remove all the play you need precision shims that have a OD no larger than the OD of the inner race. The only way the shaft wears where the bearing was is either the interference fit was not there or the bearings was seizing while the shaft was continuing to rotate.

    To Loctite property the set screw you should preheat the endbell then insert the grub screw with loctite. As far as gluing in the shaft it is the same thing. Preheat then glue in with Loctite 609. The fact is you use the cheapest bearings available. One of the biggest problems they have with getting better performance is their choice in engine tuner that is only concerned with one thing. What profit he can turn with minimal effort.

    Oh yes he is.... because he already lied to the pilots about ball bearings in 2025. 16 years after this post....

    Dr Okon looks like you had complaint about axial slippage increased rolling resistance and a question of what the axial tolerance should be. Looks like you got mad at the customer and he said he never ask you for help again. What's going on with the increased rolling resistance. I've read it and posted it here Dr.

    Hallo Dr. Okon, ich sehe, dass selbst in Crocoworld den Hobbyisten bewusst ist, wie veraltet die alten modifizierten Scorpion-Heli-Außenläufer der HK-Serie aus den frühen 2000ern sind. Es ist altes Playa… Sie wissen, dass es für ein Flugzeug viel bessere Außenläufer gibt.
