  • I see you to Dr Okon you here at my first post this morning.

    • "This results in <78% efficiency for the above motor and 35V and 400A."
      ~Powercroco~

      Hmm this is interesting since weve already derived the truth at 69%. You posted that too so this one has a few problems with its claim. You also have no weight listed in that passage the way you must think you do. Ive skimmed over it several times I dont see a weight. But a 5050 knocker weighs much more than 600 grams. You all are so ignorant it is sad.

      You go around and around in circles and will do it 1o years for a difference of .23 Nm You all do a good job of wasting the hobbyist time. Everything you are showing is old conventional windings. Nothing is new about any of it especially a lap winding. In which there is zero reason a 24Slot 8 pole machine doesnt eliminate the problem of high pole counts.

      XNOVA already makes that and it runs highspeed with a max eta of 94% the Kw is 1. Guess I'll have to grab one to show hobbyist the true facts because some of us love to spread falsehoods into a forum.


      Like:
      "xnova discontinued it because it didnt work well"

      when the facts are that the entire new 40 series line is that.

        • The winding you all show is also the basic single layer version.

          • The reason you are doing single layers is because you cannot really fit any copper into the topology with large mono stranding and are looking for some slot space. What advantage would 12 slots 20 and poles brings that this deosn't? The Kw is exactly the same and the frequency is less. And youre right he has 100 percent pm coverage with his motor.

            The idea about coverage aslo would not explain the halbach arrays is always brought up as something people need to adopt. They are 100% coverage....

            • Christian,

              650 ma idle current with very low rpm and a high voltage winding and the Kv is no where near 1072. You throws out those little tidbits that mean zero in direct comparison with a 22 AWG test winding at Kv1072 on a 10 pole motor at 4 s lipo .

              What is the KV on this motor? about 100? where no motor makes significant noise anyway.... The hybrid doesnt care because the subharmonic is eliminated in th.is apples to orange comparisons.

              The hybrid winding are receiving world renown accolades in 2025 and you can find the winding tech in the most modern EV's esp high end European offerings. Jags , Rovers, etc.

                  • You pushed this published literature into the forum So to show the minimal loss results of such a slow runner is nothing but a skew in this context.

                    Comment


                    • It has nothing to do with the topic of speed engines and It seems to be thrusted in because the proposed 20 pole has never been produced running to this day. Gurus have to manifest their own suggested ideas to the forum and then SHOW THEM IT WORKS!!!

                      You talking about skateboards now. WTF was it suggested or even mentioned in a thread about speed engines in the first place then?

                      The motor isnt running and the skate board motors are factory wound...

                        Here's another cooling idea Ralph can steal from me 😎 See this void under the winding heads? Slide a piece of aluminum there then bend it up 90 degree and cut slit in it for end turn heat sinks at each head top and bottom. You use thermally conductive epoxy or gel to tie it all in. The big block hybrid is close to complete and ready to run for the forums. You still have not show them anything running but your mouths!

                          I have a better trick with the needle nose pliers and round wire. Dr Gerling is playing with short circuited coils in the flussperren. You weld it end to end. What do the motor Fuhrers know about it and all the possible variants Ie. twisted etc.?? Its eazy to type hype but Ralph can tell you 700 miiliamps idle on a p650 for a kv of 1072 isnt too shabby at all. if you wanna compare something bring your run less 20 pole in this haus!!!

                          Have a look at the idle currents of motors that size and kv. youll find 3 times as much so lets be quiet and wait till it has a full bobbin and more data like you have not provide to the forum on the 20 pole machine.


                          Thank you!

                          • Look at the idle current on the SLOWER 8 pole xnovas for instance.

                            Its still less than 300 Kv at 30 volts. The AC is improving. Do you see in the video of it running the sound and idle current reality on the castle? Yes 7oo milli idle get your attention at 17000 rpm so u speak on it side eyed.

                            But did you also realize that idle double at part load. Thats all in the video captured. Imagine a knocker with a idle current of 10 whole amperes now at partial load. 20 amperes idle. She waste a 1200 watts there at 60 volts.

                            I know you are a dingleberry, but its all good. I have manuals for you....

                              U can see HERE!!!! Holles Calculator set the curves appropriately if Helmut's paper is the only one valid in this universe. That also shows a level of stupidity but I wont worry about you all on the German social media riding one old engineers dic.

                              So stop with the minstrel show and record some constants from a RUNNING motor.

                              Helmut wasn't nearly as established in the field as the EE's that bring you these new winding ideas. Its so sad you think Helmut trumps it all. You are definitely limited in critical analysis holding up one mans theory for an entire forums or field's knowledge base.

                              DAMN!

You are ignorant as hell and why you can only wrap copper around iron!

                                Have your mathematician rewrite the formula for you so you understand it is the same
