Hi this is "Holle's" calculator you can put yours in it from now on.

ITZ EAZY TO TYPE HYPE!!!

Its works just like maxons 1.92 eq and all others....
Ignorant one...😟

The thread winding would hold up well under 1000 watts and 5O amps. Even with it Im above 69% at 3.1kW. Thats very close to the power a cots P650 reportedly makes from Kontronics. All the other people you mentioned are good with me Ralph. You're the only hater dwelling here and in all the winding rooms internationally.

[Clugh]

I could half the resistance winding the motor with only 20 Awg still be greater than 69% at 217 amperes and 4.5 kW the 650's easily sink that wattage You can talk to Holle about his calculator. But I also have the 4.8kW log already uploaded in this thread. The AJ P650 I wind holds 16 turns of 17 AWG which exceeds factor Pyro competition black copper fill levels.

Thanks

Do you see where the 70 Eta intersects the speed gradient....👀
6kW!

[Clugh]

Ha! you know what I propose Wunderbar! Talking about your Dresden source which is YOU camped. Get a reference for the NPD that afflicts you. That's a serious ill. Man! What a bunch of German Bologna! Dont divert because I proposed the challenge to you sweetie... Who I have even more of a head start on because you are not nearly as bright as him...like this dumb ass remote posting you do 4800 mile away.... A Straight moron and mouse of a man sliding on his pc

And an accurate head shot.

"According to my second hand information from Pinnocio from Dresden, he should have somehow got his Y-D up and running in the meantime.
This gives him a good head start over you!"
~Ralph Okon~

Yeah sure sweetheart like you know its been running on the pyro over a week now and I had it up and running 6 years ago on a scorpion goof troop. You been stalking camping in my thread for this data since then...

[Clugh]

Its you and your cronies in the lands of ignorance that can't manage it in 5 years

Prototype 12n14p YD | RC-Network.de

You need to fix home first lil' A-boy

It's really sick to lie to your friends like that. You told them you're not on this page, but you mention my name and what I'm doing here in every other sentence. All of their planes will burn this season because you don't have a solution for hot magnets.motor

batteries, motor, plane, and esc all gone... with one error from Dr Ralph Okon . Just ask the victims do they think its any room for improvement

DZhamel has easily burned through 20,000 dollars USD with these failing engines and has not a single speed record to show for it.

Enjoy the view of your work Pinocchio!

Even though you are not here!

Merian from YGE and me got u again!

I dialed him up...

"The ratio of the n-spec. from single to dual layer with 3.5% difference corresponds approximately to the ratio of the winding factors.

In practice, the single layer winding proved to be at a disadvantage despite the theoretically 3.3% higher torque generated.
The winding wire length was about 10% longer, which corresponded to an increase in ohmic resistance by just 10%.
This easily ate up the apparent advantage of the single layer winding in the tall branch area.
The winding weight has also been increased by 10%.
in addition, the single layer winding (on the model maker) suffers much more likely to suffer from the syncloss.
To do this, the housing for the winding heads, which are up to twice as high, has to be built correspondingly longer, which results in a further increase in weight.
If you build the dual layer inside (stator + magnets) this 3.5% longer (i.e. only uses the additional space required for the winding heads differently), the apparent torque advantage of the single layer is already gone."

~DR Ralph OkoN Jan 27, 2020~
WRONG! All you have to do is the math....

The disadvantage comes because the sub harmonic eats the rotor more in the single layer that is where the desynchronization comes from DC man . But YOU still have that problem with you old ass dual layer too.

10% longer wire LOL when the Dual layer has the same amount of turns /2 plus the crossover wire. That levels the taller winding head of the single layer with no crossover wire which is indeed the more torque dense machine. You also run YGE with the 6 step motor which also isn't ideal anywhere but wot.

According to LRK you also actually use 1 less turn for LRK...

"I myself will not deal with Y-D, because the result of such a winding is simply too uncertain for me in terms of desired N spec and slot filling.
The "young wild ones" are welcome to take over this and make a name for themselves there."
~DR RALPH OKON January 27, 2020~

Know why itz Pinocchio? If you had wound it then you know the basic Nspec per turn on the motor and could extrapolate just like I did.


Keep it real with yourself. The delta part is a single layer. You know exactly the nspec if you knew what it was for the dual layer. It's no different. double turns half the teeth equals generally the same Kv. The wyes are short open ended coils . they wont slow it down that much more.
Plus mr bulk winder for a profit can run his test winds the same way hes always done very quickly..

This is how i know you are FOS!!



He and martin cant calculate Kv now.? RIGHT! so he denied the potential of all these benefits for that reason? You are a fool if you believe it. I just showed you basically how you do it with the P800

so please.....

GTFOOH

You are a straight clown bruh.....

"So 12 turns of 17AWG in the single layer delta is no issue to fit on the stator half . That's at 1/2 the stators factor fill level already in the single layer. 😁That is a minimum of 12.48 mm^2 in the slot . I'm adding a twist. Upsized wye turns to 15AWG. 7 turns wye will give me 24.03 mm^2 total in the slot. A 1.6mm conductor is less than14AWG which is 1.628mm bare. A 6+6 14AWG would be 24.96 mm^2 in the slot. This point would be beyond Dr Okon's reported fill with a 6 + 6 in 1.6mm which he says was a challenge for him in the P800, so this meets or actually exceeds his copper fill. That is in the wye - delta hybrid winding topology BTW. I hope he and his friends can follow the math and the winding tech. The 12 turn sl DD should already be approx. 400 Kv so the Kv should be a bit lower finalized. It would be nice if the voltage constant was low enough that it could blend it with greater than 60 volts. The motor terminals would be 2x1.51mm for the higher voltage. The Preece value for two 15 AWG conductors is 280 amperes for 10 seconds. The Onderdonk 1 second value is 540 amperes. If it could mechanically withstand 60 volts the wire could deliver 16.8kW for 10 seconds. The 2 second amperage value he rates at would put this winding all in his reactive power house somewhere around 22.9kW the square route of the peak possible Onderdonk value is where I set that at a glance."

So either he is Pinocchio or incompetent at calculating things. You pick one.

[Clugh]

This is a P800 in 6+6 YY in 15 AWG! I had fit a 6+7 and the guy was PISSED I didn't give it to him.
Tried to create a smear campaign and Heli freaks LOCKED IT
and told the guy be quiet. I never saw the motor again.

[Clugh]

7+7x1,4 for YY and 420/V.
its 175% copper and stil a lot of room available into each slot.

its really boring. almost everybody is to lazy to read and to search and to use the own brain. the formula for this calculation is given (felt) a thousand times here in this forum!!!! seems, it is much easier to wait for someone who makes the work......... bert is right. once again: 6+6YY in real is 490/V. so for 8+7YY you will get: number of turns old / number of turns new* n spec. old = n spec. new 12 / 15 * 490/V = 392/V this is only valid for jive / kosmik esc. and 8+7 x 1,4 YY will be a challenge also for experienced rewinders.

So my projected P800 with 7TY-12TD in 17 and 15 AWG, that will fit, hybrid winding misses his best conventionally wound P 800 by .09mm^2 at 24.03mm^2 and the Kv is in the ballpark

He's telling you he cant figure these things out so why should you trust that he knows anything about it.
Is he a winding guru or just another jealous troll?

[Clugh]

Its funny this superiority complex he has because the first p800 I ever would already matched some of the top fill levels of the Germans. The 7+7 in 15AWG


Bi Bi....Pinocchio

[Clugh]

Hès in class now for sure if he cant figure out nspec. Better not speak on it remotely because this honest man does not read here rememba?
