Alternative motor windings and drive schemes

[Clugh]

Right!!! 2.4kW sounds more like its maximum reality for a 50 dollar Joker!!!!! You damn right its exhausted there.

do you see Chris? Their "empirical" chart of "estimations" is bs!

Now I have to go because I have better things to do than volley remotely with real ignorance that told you it could do 4Kw in a previous post..

and didnt I tell you id love to see it....

Enjoy your day!

Thanks

How do you determine the synclos current ?

[Clugh]

How do you if not empirically? Im interested in the answer here beacuse the other way would be alot of mathematics i do not think they can perform..

Thanks

This is only possible with YGE controllers because they have a syncloss protection, if the motor threatens to lose commutation, the current is not increased further by retracting the PWM. For this you have to log with an S32 and slowly feel your way around. Greetings Schmiddi

[Clugh]

So this syncloss current point is of no consequence to anyone but YGE user and that point is programmable I'm sure. essentially it means nothing to you if you dont run the same inverter at the same settings.

What hes posted here means absolutely nothing to the stand alone motor. YGE's they use have very antiquated design and architecture.

AND.....It must not work very well since you see the fires.

[Clugh]

YGE also has the highest resistance in class so when you wind a motor with a lower resistance than it it wont like it and this retraction of pwm will only make it more difficult for it to process low induction machines.

Syncloss for him is YGE's limits.

Thats an interesting 'UNIVERSAL" teaching concept.

[Clugh]

The amateurs aren't considering the power conjugates and impedance matching. Then you run BLAC wind with 6 step at WOT drives and lose more static output to ripple. If you are optimizing a six step drive for the max torque density it delivers then you want the most BLDC signature with the six step drive. So you would wind LRK (single layer) Deltas mostly then quiet the slots so the rotor stays cool. Everything in the world points to that for these small hobby motors on trap drives like BLhel32. I don't give a damn what the hobby industry has done. Maybe the powercroco way is to copy it.

I'll lead it if it needs that!



Hubert

[Clugh]

#1 There is no electrical merit or advantage running a low ohm motor on a high ohm drive.
#2 Sinus BEMF signature motors on 6 step drives is a commutation mismatch
#3 BLDC (six step) is more torque dense than BLAC (sinus)

Post your experts accounts studies and peer reviewed work from your posted hobby manufactures that disproved it.

Some of them are here reading so don't post fallacy show me some data!

I have plenty here in my digital file cabinet.

Hubert

[Clugh]

BORAT!

And then all that follow the industry kettle logic falls flat too because all the listed motor manufactures you named don't all use the same steel bearings number 1 and they all dont use NMB!!!! So its just more garbage to justify how cheap you are to your customers that keep having to pay for toast!

NEU does not use NMB and neither does LEHNER, PLETTI , and other high end manufactures.

You definitely wont find that standard bearing in anything industrial either. But like I say your customers are not worth 20 more dollars to you so it is what it is.

Feed your dogs...


Hubert

layta Chris this is funny....20 more dollars for electrical shaft isolation and less driveline drag.

It absolutely devastates a 10,000 dollar budget plane...

Man....u just cant be any more DUMM than that...

[Clugh]

Let me tell you something joker...😁😁 ill replace a person motor with a brand new one off the shelf out my pocket if it ensures it keeps my name good and they get what I think will work well for them especially if they are a repeat customer .

A real example.

I'm giving the small Xnova to Brenner to have for free and see how he likes it. I paid for it . Very happy to do it for all he has done for me. It will have full hybrids also which I paid for. There is no profit to be made for charities or anything else.

no person that has solicited me has even came close to complaining about my fees which actually hurt me.

I don't make any real money even though the potential is there with a higher level of availability on my part. The only reason I wound a motor for anyone is because they asked me so clearly there has to be an alternative to someone that has an issue taking a 20 dollar loss to make a person they serve happier. It just makes sense especially if you are fortunate enuf to make a real dollar off it. I feel blessed therefore I'm just not a greedy person like dat. That brings bad karma. U might get a bit of good luck in other ways if you not so greedy.

U 2 greedy and cheap bruh...

I dont care about a profit more than they win or perform well in their application.

NEVER!

Hi Hubert, This week SAW is in Munich. Today is the last day. Not a single engine burned down. New world records set in some classes. Yesterday the JAGs team rigger did a first test with the two engines of two Castle Creations Hydra-XLX2 with 8S. Nothing burned down either, but I rode the first straight quite easily at 314 km/h. Very quiet despite the semi-submersible propellers. Two pictures first. More the days. Andreas Lehner drove a tunnel boat at 260 km/h. A staggered mono boat achieved 199 km/h in its class and increased the world record in the class by 10 km/h. Happy Amps Christian

What a boat!

Congratulations on Lehner doing it with JAGs again.

It would be nice to see the XLX2 logs....The scorpion king could stand to learn from that.

And a person is not even truly an advanced hobbyist if they do not think without a profit designing or trying something new is fun!

[Clugh]

Halo Christian,

Nun hat die A-Serie Magnetoptionen mit unterschiedlicher Bogenbreite. Wenn er die verschiedenen Optionen axial stapelt, hat er etwas. Er muss das 7/8-Verhältnis beim axialen Stapel beachten. Es ist eine Schande, dass Scorpion beim herkömmlichen Sternmotor festsitzt, wenn alle Rohteile von etwas Besserem vorhanden sind. Er hat eine Spielzeugkiste, aber keine Ahnung, was er damit anfangen soll.

Es sieht so aus, als würde Dr. Luk eine einzelne Schicht verwenden. Der Amateur ist stur und denkt wahrscheinlich, er wüsste mehr als der Doktor




Danke
Hubert

GregG Speed Demon	Amazing sound, very quiet almost like a hushed EDF. Oh that sucks, never good to lose a plane like that! What size/brand cells are you using and how many cells?

10 days ago. The answer of SLS had already been posted then erased.... If the batteries were the cause of the failure you've been asked what were they....10 day ago..

AFAIK they used 10S. ("Speed" 5100mAh?) Nomally SLS. But I don't know, how old the cells have been and how good and if they have been warmed sufficiently. We already often have seen that one single bad cell in the pack can cause such problem. Same in plane or in helicopters just this yearand independent from ESC (Kontronik Kosmik, YGE 255HVT) or motor ( with Kontronik Pyro or X-Nova or Scorpion.

What you tried to erase I captured before hand because I know you.....😉




So where are the plethora of photos of burnt up Pyros or Xnovas that even fly at your backyard competition with mostly scorpions in the nose???

Where are those videos????

More false statement about the competitors. The YGE 320 you use has none of the failsafe's of a Kosmic and it doesn't run as cool the resistance is also 20% higher. The Kontronics AFW algorithm is much better than the YGE which also has antiquated on board hardware. Slow processor and dated FETs no better than a turnigy from hobby king.

Face it! Your inverter and winding style is old news by todays standards.



Hubert

[Clugh]

Excessive amp draw from the motor will kill a cell and anything else including the inverter. Its a snow ball effect....

Lets bring in truth for 2025!

The measurement in my test environment shows quite accurately the expected (good) data.
Now he still has to show the client that it is the same in the work environment.

The 5040 speed engine, which had dug itself into the ground after the elevator failure, is also still running smoothly.
Theoretically, it could simply be put back together - of course equipped with new cheap bearings - and continue to operate.
With the scars in the winding (picture in # 708), however, rewinding is clearly the better option. Appendixes

Too bad this photo isnt a 5040 and we all understand clearly now that your customers are not with the extra 20 even if the plane cost 1000 times more. Those dogs gotta be fed so I'm sure they understand if they pay 600 dollars for a 42 mm stator and a paw print on the bell, with the same old wind 😂. Clearly they do since they give u a thumbs up for unwillingness to give them something better.

You have a nice congregation of faithful subjects in your church.

Good luck on your sermon without the YGE 320 today

We can see the smarter YGE inverter in the photo Ralph.... so there might be hope for you after all.
Hubert

[Clugh]

The test environment you use UNILOG does not show you the mechanical output so you dont have anything accurately recorded about the motor but its speed and consumption . Do you think UNILOG meets IEEE sensor measurement protocols? Not hardly. You'll need more than that to write a speech about it. We already know from the data at MHZ the motors don't make any torque for the power they suck off the battery

You offer zero explanation about it. Brung up the American manufacture saying the Kv was different and it was essentially the same and the motor makes 20 Nm for its 20 kW of consumption.. and comes with better bearings commercially off the shelf. The scorpion of equivalent weight makes 7.62Nm is the report.

Let scorpion measure you motors mechanical output at 24kW you claim; why not ?????

A remote explanation would suffice .

Thanks
Hubert

[Clugh]

Hook a thermistor up to the almighty engines croco wind from unilog and record the motors winding temps at even 15kW and then calculate what your real DC resistance value is. The AC is at least 10 times higher than that number Ralph.

Kümmern Sie sich nicht um die heißen Az-Magnete und ihre Restinduktivität, da sie unter hoher Belastung immer heißer werden. Ungedrehte Bi-Filar-Leiter erhöhen die Wechselstromverluste nur noch mehr. Ich weiß, dass es dir gefällt, aber Alle Daumen der Welt in Ihrem Hintern werden daran nichts ändern.
