    A ferrite flux switch is interesting. Christian how is Aloys? Haven't seen him in post for awhile. Seems he'd normally say something on these topics

    or is he weary of the proxy war?



    If you talk to him tell him Hubert sends happy holiday from America. He gave me rolls & rolls of slot liners when I was winding the induction machine. Did not ask for anything in return. Same as you. I have respect for him away from hobby but as a good person. I know for sure good people are all over the world. For 2024 I wont make any suggestions to the speed pilots or Dr Okon. I will however try my best to implement these things here on this forum and allow them to see the data that it works.


    Thank you

    • If I wanted to truly destroy them I could and I wouldn't show them things I could use to facilitate that destruction like the slot wedges

        • Hi Hubert,

          i am working on the true .
          And i have the T-Motor with FOC esc , for this drive i build a foc boat with high efficancy .
          Have you tested the kurven diagram form Holger ? do it it is surprising . I have placed the data from the Lehner 4125/5:turn with 1 m ohm and 1808 kv ,16 amp freerunning . Tata surprise . and the zoom is super yea , i love it.

            ​Thanks for posting my concern about the same idle current. I know your data is real...However I still don't need to use Holle's free unsecured calculator as Ecalc is the most accurate with the most input variables on the www. It works very well for me. As I've said it takes me only a second to see how they bias things in their test. That was an example. I dont have time for it or believe anything they say. But I have made some calculations what lower idle current and more rpm would bring to the efficiency number. Guess I was the only one interested in that answer. Ill keep it to myself.

            Yeah naw... I wont be turning around saying I love the calculator after he post two different motors in it with exactly the same idle current and a zany superimposition. Imma leave it alone.


            That's common sense and contradictory to what I have already said. I hope my English is coming across well. Like Andreas Lehner I don't buy a thing they say. I'm sure you will enjoy it as a control to compare data since he post it because it is much easier to catch a liar if you do not trust ANYTHING they say and compare using the same calculator. These calculations could have been made long ago. Thank god the "black troll" pushed the true information forward versus 12 more years of fallacy an ignorant personal attack complete with epithet. The movement there....

            • The leaders should donate a few motors to Erwin. What good are they on a shelf? He can contact me and I'll send him whatever. a motor cost a few dollars and isn't going to ruin anyone's dog shelter financially. That is just more bs only a moron believes. The big mouths are scared of empiric head to head comparisons.

              They are 1% honest and 99% hilarious.

              I'm winding motors and in full agreement with Andreas Lehner about the site and any calculators there in Croco world. Not one had reported his 79% they are all lauding the low efficiency motor in fact so why would I trust them? Kai told you to shut up unless you have data from a plane. Gerd approved the goofy post with his thumb. Knowing there is a million motors with better efficiency. He is supposed to be the technical reference there. What a joke.

              Erwin asked for a 50mm motor so all the leaders should donate one. The black troll will with no hesitation.

                You posted the facts now wait for the response. It will be fallacy based as usual and off topic. But Ill wait for the same 20 year old response..

                • Anyway with one Pyro 650 (#55738) motor the shaft got fat for some reason on the pilot an seized the inner race on the shaft. I had to release the shaft grub screw and push the shaft out the bell as far as I could then cut the shaft in front of the bearing race to get the motor apart and that left the outer race seated.

                  Another problem Click image for larger version  Name:	fetch?id=416799&d=1700311049.gif Views:	0 Size:	158 Bytes ID:	416806

                  So I had to grind internally the 52100 stainless outer race on one side with small grind wheel so it would collapse and come out to fit new ceramics in. Id really like to find a full compliment deep groove full ceramic with no cage.

                  EXPENSIVE! and I don't care.

                  Use eye protection and at least a particulate mask for grinding everything at this point. Everything's a health risk. An approved covid mask works. I'm sure everyone has one of those....

                  • They never understood. A full SiC bearing would be as close to diamond hardness as possible. They will not flatten the ball with a little speed plane . The thermal conductivity of the bearing is like something they would have never seen man made on earth. They would not want the cost just to play around with it.

                    • Ich habe mich gefragt, ob pyrolytischer Graphit, da er über einem Magnetfeld schwebt, in einer Strömungsschalterkonfiguration verwendet werden kann. Ich frage mich, wie hoch seine Permeabilität ist. Ich weiß, dass Dr. Hendreshot nach einem Material mit negativer Permeabilität gesucht hat.

                          Here is a single layer 700 MX Align tuned for an 1/8 scale hydroplane. it is 7 turns of 13AWG. in a skipped tooth parallel wye. 52% increase in copper cross sectional area over the stock winding if I'm not mistaken. If someone calculated less it wouldn't matter to me as much as the measured results, Right?

                          The constants are posted so a person can run it through whatever calculator they want. they can fudge it to make it look bad too I suppose. Desynchronization is not going to occur with this motor at 141 amperes on a castle inverter. Load it into Holle. I care less... I'm tired of doing calculations for leaders.In the past this has been nothing the leaders have wanted to do with my recorded constants. Maybe empirics and 79% Eta's on the shelf in abundance brings more courage, so load it up.

                          Thank you

                          • If you are told your post is off topic for the T motor thread you can post it as the reply in the Lehner thread. Its certainly on topic there...and what they have been dearly waiting for. They can criticize Holle's calculator there.... with the comparison Audiosmith made.

                            • Hi Hubert,

                              I'm waiting for their answers because they'll be nonsense. They can't write the truth; they would immediately declare themselves incompetent.
                              Just read Audiosmith's last answer in the Jocker Motor tread that he wrote there. He writes that windings stick together, and forgetting them is nonsense because it hinders the transfer of heat. If you do it with your ignorance, He is right. But if you do it correctly without air pockets and with thermally conductive casting, the results look completely different. But it's better that he has no idea about it, then everyone else who does it has the better cards in speed flight. Thomas is the best example of how much ignorance is spread on the Internet by such super-informed people. That's what I meant by carrying out the truth next year. You have already done this successfully and imparted speed flight knowledge to engine hobbyists. That's how it works, I'm completely behind you and will do the same.
                              Unfortunately the Kai is quite stupid. He wouldn't have flown a single fast flight without me. Without me, the Okon would have no idea how to make higher-performance engines. Martin Götzenberger confirmed this to me in a phone call just four weeks ago. Back then they only rewound drive motors and had no idea about better sheet metal cuts. That is the truth and nothing else.

                              What would you like to know about pyrolitic graphite? I have some of it when I was developing fuel cells and I had very good contacts with SGL Carbon Werk. Back then I had some plates specially made there and also deposited thin layers from the gas phase myself. I've had a hooded disc floating around for a few decades. It is perhaps the longest floating/flying thing in the world. My little UFO flies and flies endlessly. As frictionless, you can detect and measure even the smallest flows. In a vacuum chamber, the parts also have no air friction. We always wanted to develop some kind of sensors with it but somehow never got around to it.

                                Is that what he said about the UHU they used for years and just stopped 4 months ago when I showed them the correct material in this thread

                                I agree totally 😉. It's not an American product so I've never used it to secure wires but according to spec its a pure insulator and not thermally conductive, stable or made for securing motor or transformer wires. No it wouldn't make sense to paint a heat sink with it. To secure the heatsink thermally conductive diamond paste works like SiC and pyrolytic graphite has superior heat transfer to be a heat sink. You typically do not use the same material to adhere a heat sink as you would to secure motor coils. The materials have a totally different poise and typically the material or gel for securing heat sinks have and ever higher thermal conductivity than thermally conductive coil securing adhesives.. The right material also does not have to be vacuum impregnated to work really well. People truly versed on the material or that can read here would know this as the information has already been posted. I'm not retired with nothing better to do so I wont waste my time showing slow people the same thing over and over again even though that's what has been the case with the German social media the last 10 years. Make ignorant declarations and go round and round in circles on a forum like fools when the published information is available to the rest of the world. To continue to carry on is stupid to me.

                                "We recorded a flight with the lowest energy consumption I have ever seen with my setup, 2600mah for the P25 schedule. Typical power consumption for P25 is 3800mah. The motor also ran cool as well. With an ambient temperature of 28C, the motor was 65C on the outside of the rotor."

Does everyone get that? Apparently not Christian. I apologize for the obvious ignorance you fight. Thomas is a really sad case. as he winds on your invention.

                                    Gerd lässt den ignoranten Bastler davonkommen, bricht sein Moderationsversprechen und kassiert die nächste Beleidigung. Ehrlich gesagt ist er schlimmer als Ralph. Aber sie sind beide dumm in ihrem Handeln. Wie Ralph glaubt er, die Fähigkeiten anderer zu kennen und zu wissen, was sie können oder nicht können. Genau deswegen bin ich jetzt wütend, damit sich diese beiden Idioten nicht so besonders fühlen, weil sie nicht bei 79% sind. Immer reden, aber nicht das Align für seine Freunde in den blöden Computer laden. Und sie werden es auch nicht laden, um die Hoffnung für ihre großen Kopfwickler am Leben zu erhalten @ 79%

Another horrible analogy versus data. I guess that's all related to the t motor? See the ignorance ? The poster blue achieves 90% with his winding machine. So all this post instead since your hand only does around 60%?

                                      This site is technically worthless. They blew right past the issue of two motors with the same idle current! and incorrect slot fill calculations. This is why the site only serves to bring me daily humor. It's the same old crap with no explanations about the mediocre efficiency reactive power queens.

                                      Christian you should repost the real fill data of the motor again . The nonsense is immaterial and not acknowledged by the field. That's not how it works in real life with engineers. Fallacy doesn't bring solutions. The thread isn't about Blue's hand winding ability its bout the self aggrandizing lies Thomas Schmiddy and the reptile post on the forums and someone catching them on it through mathematics

                                      Dig deeper into the winding program. You will find more errors so post more data with zero fallacy. Seems there was nothing to say about the much higher efficiency the Lehner showed. Hurry quick and skip past it....

                                      Repost the data as the answer in the Lehner thread. Then they are in your room and it is on topic. I told you that was going to be the escape route in the previous post.

                                      Its common sense after 10 years.... Blue should have let your post stand alone.

                                      • BTW Christian I have provided a BOM for a KOMAR smart embedded inverter. If you goto my profile page and click on the media tab you will see the KOMAR BOM. Soon I will secure it to only subscribed members. If they want to view they will admit it and be required sign up here . The photo of the drive attached to a motor is actually the Sadulli and open hardware integrated drive reference design based on the Mitochondrik LV IC form Zubax robotics.

                                        Ill put all inverter ideas here for safe keeping. You have friends and advanced hobbyist that can build it same as me.

                                          Attached is the fill that Blue achieves.
