Alternative motor windings and drive schemes

[Clugh]

Chris,
ich muss heute Geld schicken. Petr ist bereit, das Flugzeug zu schicken. Ich werde ein paar 600er-Motoren für den Super Chief wickeln, aber ich bin mir nicht sicher, ob ich den lieber hätte als den Getriebeantrieb von Steve. Sie sehen eher wie ein Rhobust aus.

Hi,
it works, almost everything has been achieved, croco pages are online, here again something is produced and shown and technologies are taken up that are useful. In the case of engines, soon probably also in model making, actuators with vector strategies will find their way in, Hubert has recognized this correctly, you just have to read and learn to understand his mail. For such actuators, however, motors are needed that can handle many more clocks in high frequencies. Many roads lead to Rome, we have small plates with the technology in the cigarette box format that can do this, but are developed for a company, industry, which do not want to have anything to do with model making, I asked extra.
A few more pages that show what it's about, https://www.elektroniknet.de/automat...hen.29514.html, read all 3 pages.
Thomas, this does not rewrite physics, but it is better to deal with the true magnetic conditions and from this a higher efficiency with all the gains is generated.

Happy Amps Christian

PS : Ralph still has sheets from me from Impfy, the 0.07 mm thick, which are eroded, but then have to be annealed before they are glued packed. They are then buttery smooth, but have very low losses at high, highest frequencies.

Yes, that's right.
They are still lying around - you are very welcome to have them back.
They are much too good for my old-fashioned tinkers anyway.
Maybe your friend will make a fancy multiphase multilayer parallel slot "clugh" out of it, which he then controls with a multiphase FOC controller.
Just need your address (PM) again, then they will go out on Monday.

Ralph ,

You say you tell the truth so where are the sheets. That Monday was over a year ago. Its funny what you speculate I can build but

BUT WHERE ARE THE PLATES?

THEN MAYBE ALOT IS POSSIBLE!

Thanks
Hubert

Schick Big Mouth die Adresse Chris.

Christian, ich kann Dual-Inverter betreiben, die bei LRK oder DLRK um 180 Grad versetzt zünden, was die Belastung des Rotors fast vollständig eliminiert. Zwei F3 40 APD wiegen nicht mehr als ein halbes Gramm und können Spitzenwerte von 100 Ampere pro Seite erreichen. Sogar die beiden F3 80 wiegen nicht mehr als ein yge LVT 65. Sie können die Kommutierung noch weiter optimieren, indem Sie die Ein-/Aus-Zustände der Transistoren in jedem Inverter leicht ändern. Ich brauche keinen schicken FOC, obwohl APD das schon hat und 6 Schritte und Big Mouth immer noch süchtig nach YGE-Kinderprodukten ist. Lassen Sie sich von A Boy die Platten schicken, damit er alles sehen kann, während er mit seiner Powerditto-Site voller Ungenauigkeiten da sitzt und versucht, von mir zu lernen. Wenn er etwas wüsste, wüsste er, dass eine Statorhälfte eine Falle erzeugt, aber da er die Theorien nicht wirklich getestet hat, faselt er einfach wie üblich weiter.

[Clugh]

Ich werde den Speed Klan zum 100. Mal zeigen

Ich warte darauf, dass die beiden Experten von Croco World und der Elektroredakteur in den deutschen sozialen Medien eine erste Lösung präsentieren. Wir haben hier viele Möglichkeiten, die Motorleistung zu verbessern. Offenbar sind Ralph und seine Freunde nicht so fähig, wie sie denken, wenn sie keine umsetzen können. Bewährte Lösungen sind Realität, powerditto nicht. Das ist nicht nur die Meinung eines Amateurs und seiner 20 Freunde, die alle ihre schlechten Ratschläge von ihm bekommen.👍

  After the isolated magnet defects in 2 motors in operation with the YGE 255, I withdraw my recommendation for the controller together with my motors in maximum load operation.
  
  After extensive discussions with Heino, I received the information that when the syncloss protection is activated, the controller regulates back to just below the last valid signal and remains there and does not turn up again in this session even when the load decreases!
  This means that the motor is - depending on the operating parameters - permanently operated with 95-99% partial load without any real feedback, instead of commutating with solid blocks. This increases the losses in the inference and in the magnet to several times the losses in full block commutation and may lead to the magnetic force losses seen!
  With the loss of magnetic force, there is a cascade effect, because the n spec continues to rise the more the magnets lose power.
  Without checking the setup by the user, the engine dies insidiously.
  Of course, it's the user's fault because he doesn't notice what's happening - but the controller doesn't make it easy for him to recognize the situation either.
  
  Why btw. the impostor does not tell his POC buddy that he received his 0.1 cobalt sheets back more than a year ago as agreed and stated here in the thread and acknowledged their receipt, I don't understand.
  He wanted them back above all so that the POC boy could build something really good out of it!
  But it fits well into the familiar overall picture.

Aber der kleine arische Junge aus Dresden, der kein Ingenieur ist, liest hier nicht. Hier ist dein Beweis, ^^^

OOPS!

Brauchten Sie Heino, um Ihnen zu sagen, dass Ihre Magnete sind? Und der Wechselrichter schaltet entsprechend ab. Was ist mit all den Bränden? Kann der A-Junge einen von ihnen auslöschen, ohne ein Patent oder einen Abschluss zu haben? In Dresden ist das alles abwesend.

Ralph you know

Die xnova und pyro 600 sind auch beide besser als der Skorpion. Sie sind leichter, effizienter und besser konstruiert. Hören

Xnova und Kontronics sind bessere Motoren.

An HK 3226 is 239 grams and put out 1770 watts continuous
A pyro 600 is 235 grams and puts out 2000 watts continuous

Rechnen Sie nach

Auch der Skorpion, so berichtet Thomas, zerfällt bei der erforderlichen Drehzahl.

Genießen Sie den Unterricht

Sie haben eine Million Probleme, da fast jeder Beitrag eine Reparatur ist. Glauben Sie, dass christliche Abschlüsse Ihnen helfen würden, eine Lösung für Ihr Problem umzusetzen? Sie beschuldigen den Betrüger, aber Sie sind derjenige mit dem Motor und dem Antrieb, ohne Lösungen, um schneller zu werden.


Ich habe Ihnen drei Lösungen gegeben. Kann Ralph Okons Abschluss eine davon bewältigen?

Slot wedges
dual inverter
Hybrid wind

All are a solution to your poor rotor performance problem. What is the hold up. It isn't Christians degrees or your remote epithet that will not make it happen.

Happy are those who still have the good old yge 320s.
These ESCs were ideal for speed flying and heavy-duty.
There is currently no alternative to this.

Mfg Michael




Sure Crocoworld....😁 there are several inverters that performed better in head to head comparisons. YGE basically came in last. It ran the hottest too with the highest internal resistance in class. The 320 isn't any stronger than a castle HV200 based on internal resistance. The castle for instance has a much more innovative commutation algorithm to take heat of the fets. It can surge over 380 amperes and cost half as much. The HV Pro APD is def a BETTER alternative and cost double a YGE320 or the reptile would not have it plastered on the latest pages of power ditto. Micheals handicap is the scorpion engine in his nose.

The YGE 320s fry with it and smart inverters say the motor is spent and can give no more useful power. Based on all the repairs it looks accurate from here.



Thank You
Hubert

[Clugh]

See APD logs directly from power ditto? Crocoworld customer posting (Micheal) has purchased APD himself 😀. Ask him why didn't he get another YGE.....🙄

Here the APD is on a 5050 speed motor from Ralph. APD has already flown over 600km/h and it didn't burn up. Its very suitable if you don't want yge's fires destroying your entire plane!

😀



Ill post the truth for every lie..... Its smaller and lighter than the YGE and twice as powerful.

Michaels auf mit Ralph versetztem Kool-Aid. Es wird für Crocoworl immer schwieriger, seine Lügen aufrechtzuerhalten. Er vergisst seinen vorherigen Beitrag.

jeder, der kein Betrüger ist, glaubt nicht, dass der 3-polige FET ein moderner Schalter ist

[Clugh]

For a Speedfire2 for example dual APD F3 80 inverters are 40 grams of inverter which equal 9.4kW @ 8s lipo. The rotor performs better because the subharmonic is cancelled. He knows the pyro and xnova 600's perform better in power to weight. He knows both motors also provide better cooling than a scorpion HK.

[Clugh]

Its too bad the speed klan doesn't not understand how motor agnostic inverters run which is actually good since they haven't a clue about the quadrature and direct axis inductances of their machines to set the bandwidth ratio appropriately. In the case of APD it does that for them and APD does nothing at the factory a competent modeler who can follow directions cant do at home. It is not their fault if you dont take the time to learn how to set up the inverter which can be by the factory before it is delivered. The fact that PWM and timing are auto ensures optimal efficiency and commutation at all times. They never knew where to set those anyway.

Der Goofy hat immer noch nicht das Problem des Rotorschadens, der die Ursache für die Dyssynchronisation ist. Jetzt beschuldigen sie die Ingenieure bei YGE, nicht zu wissen, wovon sie reden, weil sie ein Protokoll von Thomas hatten und es interpretiert haben. Die Ingenieurwelt muss ihr Buch umschreiben.

LOL, gib mir eine Pause. Was für ein Hochstapler er ist.

[Clugh]

Diese Jungs sind wirklich im Rückstand. Das YGE kommt nicht einmal annähernd heran. Im Vergleich dazu fehlen ihm etwa eine Million Dinge, von der PCB-Qualität bis zur Komponentenauswahl. Das YGE ist ein echter Dinosaurier wie Ralphs Motoren. Der Mist ist veraltet, aber der Unsinn aus dem albernen Geschwindigkeits-Iklan, den wir sehen, ist aktuell und auf dem neuesten Stand. Welcher fortgeschrittene Bastler hat den Testbericht zu diesen Laufwerken nicht schon gesehen? Sie müssen auf den neuesten Stand kommen. Und immer noch keine Lösung für den überladenen Krokodil.

[Clugh]

Protect the wires and lower load amperages.

[Clugh]

Hi Christian,
Specifically reinforced for speed my Speedfire2 guise is like this but black where this one is blue. Petr loaded it with KST servos. The reports say the gear drive pushes the possibilities but I didn't see where the direct drive outrunners were wound to produce 12,000 at the prop. Even though there are inverters made to run external rotors at high rpm the iron loss compared to a 2 or 4 pole is high and translates to heat. Running over a kilo in fundamental does that. The required commutation frequency is also higher with the 10 pole machines. In my mind part load operation isn't a point in the speed trap. Torque and power density is so Id strive for a BLDC system for high speed and high power and not a YGE for helis anyway. Otherwise seems like you should wind a slow turner with a lot of turns and stay direct drive with outrunner which keeps the iron loss down. A high speed 3 or 4 layer wind would work with an outrunner too.

What's your opinion Christian? Neu doesn't make alot of fast turn outrunners but they are very clean.
