  • And naturally when I came to this forum to share the unutilized winding technology straight from ABB and the big dogs with a new group of modelers Ralph you followed "anonymously" as usual.....

    https://www.hobbysquawk.com/forum/el...370#post386370


    Its all good not mad about it just remember in 2024 my time with you is over. I have to focus. We plan to build a SiC based inverter for the hobbies and EV. I'm working with Pavel and his team of engineers at Zubax Robotics. U see the link and see the tech. Its state of the art from Lithuania . You will also like the shop ALOT to really build some nice things. Thats my focus and thats what you wanna see. Hybris windings built on lightweight composite bodies featuring loss core materials with high permeability. And It wont cost the beans in CoFe laminated stacks. The other thing you know you would like to see is a flux switching external rotor in a rc model plane.

      • I love tech so much I cant stop talking about it. I saw the discussion about the lap wound hairpins with your motor and the difficult in manufacture. Guess what? You can spot weld the copper bars in a kitchen lab with a lithium super cap.. It is the large Maxwell type that looks like a D battery. I have one. When I find it Ill post the photo. Lap is basically a half turn wind in my view but you can wrap it in a sinusoidal manner with multiple overlapping layers. Half turns and whole turns used together get you into the uneven coils sides theories in Munich that have produced the cleanest 12N10P ports in the world. But also understand their split tooth 14 pole SL was the point blank winner in torque production with a wind factor well above 1 🤓

        To help yourself what id like you to do is compare the FFT between the two machines current waveforms in generator mode. The BEMF line voltage is only one half of the equation that delivers us power. Then load the generator with a light bulb or whatever needs the juice and look at the waveforms again.

        • If you want the 12N10P hybrid tested ion the German speed flying scene it doesn't matter what Lehner Neu and Pletti have done. What are you going to do?

          I also will say this one last time and if you cant get it you are slow. The slightly higher dc resistance is a moot issue and youve been told that many times . It doesnt matter because these companies will not use a winding technique that produces the elevated Io's axial bifilars will. Dont U notice they dont use bifilars nor do they have pages of repairs on the forums? Your are in a class all by yourself as far as the field is concerned .

                Hi Evan im sorry you have to go back to post 3 to understand possibly. Dr Ralph okion is in this room as "boho1" he just does not want to say anything here directly, he replies remotely on rc groups and rc-network.de. He likes to post where there is no technical rebuttals

                He hasn't said anything more because he tried to link you all to a complaint thread about a pyro I wound that some guy never paid for/ They locked the complaint thread and totally erased his friends threads he attempted to link you all too so now you get the silence and the appearance Im talking to myself. Its weird as heck I know and Im sorry but this is the way he does things..he cant communicate with me directly in front of his friends. Youd have to ask him why...

                  I wish but not at this moment but that is coming my friend. I dont mean to alienate you all but I have to deal with this German winder this way. he doesnt like an American being relevant in technical discussions because he only want to sale to you. The method is to deny all the new tech and the better manufacture to continue doing so. he will say things like the Chineese engineers are incompetent engineers but scorpion is based in hong kong....😀

                    He started out denying the winding tech 12 years ago but now they want to use it and in particular a wind I derived with the help of Dr Sariful Islam at ABB. Dr Kosta Kanellis has seen the work and suggested I show him no more because people steal! The winding tech in question is already used buy the high end e-mobility manufactures. ​Like Jaguar and range rover. . He also does the other thing like try to make a yge 320 the worlds best inverter when it simply Okay. Turnigy has the same hardware the Germany stamp means zero to electronics and how they work. Im tired of watching ,y fellow American fall for the hype. You need to measure your motors so you know how they truly perform yourself. Ive found many vendors bend the truth. I had a colleague that designs for :Lehner we've fallen out because of this. Lying to you guys to sale you something is not what I'm about. I love a good debate but they haven't given me one. If you subscribe you will see all the motor forums do is go around in circles over the same topics. They are boring for me the speculate on proven technology. For me that's a waste of precious time. If you really want to know what something does u have to build it and try it. Keyboard jockeys dont ride prized thoroughbreds.

                        He comes here for what he is interested in but I promise you all at new years its over. Im leaving them to their failures. I'm going to carry on with the modelers that care enuf to measure and you all may share ask question and correct me if you see something as wrong. That is not the problem with them I've been met with everything from racial epithet to all forms of fallacy. That was acceptable on those forums but the truth was not! They refuse to pull out diagnostic equipment for true examinations of the motors because the equipment truly show you the consumer what's there. You dont have to be able to interpret it. i can and would post it so they do not care for me on the forums their friends run. They are all a hustle and I dont want you all falling for it. Ive associated with them and itrs not where you want to be. Trust me. That said im going to show you all the work win lose or draw. Weve done the calculations and are already 3% more efficient and more power dense than him with a quarter of his idle current. IN A CONVENTIONAL WIND so Im really worried if the hybrids can sink him. You dont need to buy a scorpion at 500 euro if a cobra for 150.00 is as good or better. Off the shelf it certainly seems to be.

                          See for me APD and YGE aren't the only options anyway. Its all about a modelers exposure to what's truly available. Most people are not going to spend the money were talking about.Theres is no point to lie to hobbyist I run APD and Castle but there is definitely other good things out there.

                            Very simply this is the topology we are talking about that produced 3% more torque than a conventional wye wind. My proposal is special because it add a 5alpha shifted winding set on the same stator that further attenuates sub and super harmonics. It reduces total loss by about a half and that's huge. Powercroco running unloaded motor test on the subject matter certainly isnt enuf to be published and accepted in my field of study.

                              They will tell u its theory but its already been proven in the most discrete engineering labs in the world..

                              • For the RC forums What I need is a pylon pilot that wants to challenge the speed records and we will provide them a motor that can definitely compete. Ill do that for FREE! Up till now most of the Americans on those forums have been nothing but idolators and that doesn't make for a good competitor. The see the crispy motors and still throw the thumbs up. if it was a Neu burnt up like that they would give stave all kinds of grief. Its amazing to me and embarrassing as an American.

                                Coz all this you see from the eastern shore is certainly the best money can buy 🙄

                                  blah blah blah but ill be rewinding and rebuilding cobras anyway.... they are 14 poles lighter have better axial cooling and much higher efficiency.

                                    We don't have time to test hybrid scorpions for scorpion. Their green garden dwarf can do that. I dont have the time. I wind other brands and in particular neu or xnova would be my high end choice. I also like the ego drift . Ill rewind anything for a small fee but I wont coordinate scorpions R&D. If an unloaded loaded motor test on a static bench for 5 minutes tells them what they need to know about the subject matter so be it...😀 But i promise you it gets more interesting here in 2024! As long as the good lord allows me life. I don't have any interest in the same old Croco motors and winds that come back burnt from black box moments. We all are free to our own choices but I'm never buying that. The planes his friends build are cool on the other hand. His props are more interesting than the motors but even those are restricted to people that run mostly him so they have plenty of layers of truth protection. Its a quid pro quo situation when you deal with him. DZHAMEL cant say much even though he prodding him with that antiquated speed control because he wants to maintain an open door to the props and motors. Its a sale your soul proposal.

                                    U see he did not post the 603 logs from APD and made the video private.....😀 Im not talking about him behind his back because i asked hime personally is he powercrocos puppet right in the video comments. Hde said no and hed poet the logs. He lied and aint post a thing. then PC comes back and no he flies 610 with a BURNT yge & motor......DO yall believe it? 🤣
