    Who care about your pure opinion where is YOUR data? You wound the Gerling wrong Ralph and it is not for a 12N10P anyway. It requires a shift of 5 stator slots so it has to be executed on a 24N10P.

    Gerlings winds are published and used in industry and very effective. All you are going to do there fill the pages with conjecture and fallacy is so I'm ready to have this goofy remote debate.

    Look what thread is at the top of the German social media now..

    Er ist witzig Ralph.

    Er zeigt Ihnen ein Papier, das darauf hindeutet, dass die Unzulänglichkeiten der Handwicklung durch die Verwendung von gepresstem Litzendraht, wie beispielsweise seinem 41LMT, überwunden werden können. Dieser hat diesen bereits und läuft nicht besser als der konventionell gewickelte High-End-Motor. Die Nutleckage (offene Nuten) und das Rotorgewicht des kleinen Motors machen jeden kleinen Vorteil zunichte. Deshalb ist der Motor in seiner Klasse auch nicht effizienter als andere. Er verwendet außerdem kein wärmeleitendes Spulenepoxid oder Aluminiumdraht. Wo ist das in seiner Maschine?

    Warum sollte die gesamte Bastlerwelt sie nach seinem Modell bauen, ohne einen signifikanten Leistungsvorteil zu sehen? Die LITZ-Idee wäre cool, wenn die Anwendung tatsächlich Grundfrequenzen über einem Kilohertz erreichen würde, aber diese „Hochgeschwindigkeits“-Motoren, wie die von Dr. Okon, erreichen diese Werte nicht einmal annähernd. Brusa von den Bayerischen Motorenwerken hat bereits eine Studie veröffentlicht, die den minimalen Vorteil von LITZ-gepressten Wicklungen gegenüber Haarnadelwicklungen, die in den AC-Steckplatz passen, zeigt. Der 4225 Scorpion hatte eine höhere Leistungsdichte als sein 4125. Dies ist eine Tatsache, die auf den GSM-Berichten basiert.
    Die Arbeiten gehen nicht auf die Unterschiede bei offenen Steckplätzen ein.

    Durch eine Designänderung, bei der zwei kleine Löcher über die gesamte Länge der Keile verlaufen, kann ich den Lagerschutzdraht in jeder Nut um den Motor führen und die Wellenspannung des Lagermotors um zwei Drittel des Normalwerts reduzieren. Die richtigen Ultraschallfrequenzen können zudem Kavitationsschäden an der Kugel verursachen. Dieser Draht kann auch spiralförmig um jeden Wicklungskopf gewickelt werden und bietet so eine zusätzliche elektromagnetische Abschirmung.

ID:	429302Diese wurden perfekt für einen HK 50er Scorpion entwickelt. Sie bestehen aus einem Carbonyl/PLA-Verbundwerkstoff, sind halbmagnetisch und verlustarm. Dies kann den Stromverbrauch der Maschinen im Leerlauf und im Betrieb reduzieren und so die Effizienz steigern. Sie schützen außerdem die Rotormagnete. Ich kann sie in magnetischer oder nichtmagnetischer Ausführung für jede Hobbymaschine fertigen.

    Why not insulate and wind pure Ag? Thermal conductivity​ 429 W/(m⋅K) the electrical resistivity is 15.87 nΩ⋅m (at 20 °C)

    Cu is 401 W/(m⋅K) its electrical resistivity is 16.78 nΩ⋅m (at 20 °C)

    Al 237 W/(m⋅K) electrical resistivity 26.5 nΩ⋅m (at 20 °C)

    Clearly the silver coil is what will allow you to run the most compact and power dense machine. If you increase stator volume for Al the weight advantage of the AL coiled motor is lost and it is also the worst conductor and has the lowest thermal conductivity of the three.

    You two sure it doesn't work?

    I'm glad to see the leaders are onto Aluminum Oxide. A thermally conductive compounds. I wonder when you will start using it on your most current hobby machines?

    Thermal conductivity


    The theoretical thermal conductivity of hexagonal boron nitride nanoribbons (BNNRs) can approach 1700–2000 W/(mK), which has the same order of magnitude as the experimental measured value for graphene, and can be comparable to the theoretical calculations for graphene nanoribbons.[30][31] Moreover, the thermal transport in the BNNRs is anisotropic. The thermal conductivity of zigzag-edged BNNRs is about 20% larger than that of armchair-edged nanoribbons at room temperature.[32]

The 3M TC2810 is boron nitride based. I want you to see how far you lead a forum a stray trying to hate on Us. I want everyone to understand why Im at you two. I have both materials here and use them both currently in 2025 not 1995!!! Youre running around telling people what works but are just now exploring the material in discussion.

    And now one has been using it for 30 years and anodizing COPPER coils but in 2025 they use UHU. with holes in it?

    Thermal conductivity
    Atomically thin boron nitride has one of the highest thermal conductivity coefficients (751 W/mK at room temperature) among semiconductors and electrical insulators, and its thermal conductivity increases with reduced thickness due to less intra-layer coupling.[75]

    Oh and BTW this thermally conductive epoxy I already showed you all is aluminum oxide and Boron Nitride based in a silicon polymer. its stable to 200C. The 3m TC2810 Ive willing shared with you is Boron nitride based.

    e motor with more efficiency | RC-Network.de

    Halo Ralph,
    Endlich meldet sich Rocket Worm mit Fotos von 30 Jahre alten Spulen zurück, die er nie in eine 40-50-mm-Maschine eingebaut hat. Ehrlich gesagt, die 14- und 20-poligen Spulen, von denen ihr gehört habt, solltet ihr einfach vergessen. Er hat nicht nur in fast jedem Motorbeitrag der letzten zehn Jahre Fotos von den Spulen gepostet, sondern sie sind auch in den letzten drei Threads zu finden, an denen er mitgewirkt hat. Irgendwie haben vorgefertigte Spulen für ihn mit jedem Motor etwas zu tun. Wenn er das gemacht hat, worüber ich vor 30 Jahren gesprochen habe, warum hat er dann nicht Aluminiumspulen statt Kupferspulen eloxiert? Und wo ist die Hobbymaschine mit eloxierten Aluminiumspulen, die er gebaut hat? Ihr wisst schon, eine zwischen 40 und 50 mm. Er sagte auch, unser Motor hier habe nicht funktioniert, aber seine 41 LMT-Drähte sind in einem reinen Isolator mit zehnmal geringerer Wärmeleitfähigkeit eingeschlossen.

    Wenn er das gemacht hat, sollte er euch die Effizienzdaten wie Lord Industry liefern können. Persönlich glaube ich nicht einmal mehr die Hälfte von dem, was er sagt. Er ist sicherlich stolz auf die Spulen, die es nie in ein LMT oder eine andere von ihnen hergestellte Hobbymaschine geschafft haben.​

    Wann wird er endlich ein RC-Modell animieren? Und warum enthält sein neuestes Design nichts davon? Nicht einmal wärmeleitenden Spulenklebe

    Das, was er hat, ist sicherlich branchenführende Qualität. Er hat über unsere Spulen gesprochen, also wo sind seine VIP Al2O3​ -Spulen?

    You could also tell your friend about passive filtering... from what I've seen emotors only look out to about the 50th harmonic to make THd calculations. What the motor actually emits in harmonic frequencies will depend on the fundamental frequency of the motor. . Passive filtering ability will also have to consider the wavelength and resonant frequencies of the source and filtering material. There are formulas to determine what frequencies will cancel or summate based on that. Passive filtering won't likely have a sharp slope either. With digital filtering on the inverter signal side you could have filtering to the 8th order. Then your LOW PASS, notches and band pass filters have the ability to be much more frequency discriminant. The sharper slopes are better.

    Active filtering is possible with APD pro and BLHELI32 architecture based inverters..

    Build you a large BLHELI32 bit based inverter with a robust 3 phase bridge..... and its much more capable than a YGE 320....

    ​​Aluminium oxide is an electrical insulator used as a substrate (silicon on sapphire) for integrated circuits,[40] but also as a tunnel barrier for the fabrication of superconducting devices such as single-electron transistors, superconducting quantum interference devices (SQUIDs) and superconducting qubits.[41][42]

    Hi Dr Okon i see you here reading. You can tell your friends this since you "experts" banned me from the site years ago for correcting you on such subject matter.

    Hi,
    This just came in, but I have a few other lubricants to share with you. You can also get it in dry powder form or EP grease. This stuff would also do well in a gearbox or transmission with metal gears and components.

    Oh! and by the way I also have a SKU for the UDL process at BOCA if anyone is interested. You make your bearing order then you use the UDL SKU to specify your quantity.

    Up to 25mm the UDL treatment is an additional 19.98 cent per bearing so of course you might want to find cheaper alternative if a 5 dolla generic NMB steel bearing taxes ya pilots wallets..

    The aerosol can was 50 dollars for 13 ounces!!!

    Enjoy your what's app discussions....try not to cause any more crashes in learning.

    ​Id like to share here a few things about electric motors and inverters that I have been exposed to over the years. Hope there will be interest here (filedata/fetch?filedataid=91738) ​ Thank you. THE REAL 1BOHO.

    Dr Okon
    Im glad to see that the German social media is now onto thermally conductive compounds on the wires and how that improves efficiency. Aluminum oxide is interesting as a coating. It is an electrical insulator yet it has a thermal conductivity of 30 W/mk. It also can occur naturally as Corundum crystal. Saphire and Ruby are in the Corundum family. At my place of employment we grow it and the SiC boules. But what is interesting about the aluminum oxide as it may work even better on aluminum windings than copper because you can get a very uniform and thin insulation by hard anodization.

    Aluminum Oxide
    Did you know Aluminum Oxide is also in sunscreen and nail polish so you may be able to paint the wires with nail polish or wipe them down with sunsceen. .

    To me it makes better sense on the aluminum windings because it can utilize better the high thermal conductivity it has. In this case, the conductor itself is the limiting factor.

    Cool Therm 320 that I tried to tell you about several months ago contains zinc oxide, which also has good thermal conductivity and does not require a VIP process to work really well. The data I have already shared with you several time that it increases the efficiency of the machines. It is 3.2 W/mk so you could only imagine what the Aluminum Oxide is capable of as an improvement to keep the working motors winding resistances lower by keeping the wires cooler
