Winding of the current Kontronik Pyro 900-520 | Page 4 | RC-Network.de

HI Ralph
Im reading it so please be sure to post the idle current and resistance of the machine. If you don't no one can calculate the Eta. Is that intentional?

Interesting...🤔

Ralph,
on the static stand... is that a pc cooling fan slapped on top of one of the newer YGE with "better" innovative RCT cooling...😀
How much does that brick weigh without the pc fan Ralph? You know I know.😏

You told RC groups a "DUMM controller" like a YGE 320 with no heat sink, and no current limiting was better suited for speed flight than a 1700.00 PROHV from APD so what is the 600.00 dollar 255 on deck for? You told Steve Neu your motors are not running into saturation so where does the de- synchronization come in that always seems to occur somewhere between 300-450 amperes? He made sure he let me know personally that he replied to your post about APD on RC groups.... We expect bigger numbers from you this year since they "aren't saturated" and you're running the DUMM YGE 400 inverter as you call it but the 255 certainly isn't "DUMM"

THE YGE Opto 255 has the innovative RCT cooling design and the intelligent current-measuring and current limit, which provides a cool and safe operation without any hard cutoffs. The Navy version has a special watercooling case and bigger capacitors.

Maybe you should also go NAVY! since you are testing one...😉Because that's some sad electrolytic support at the claimed power level. Is that even 1000 uF with the 400? on a test bench for ampere levels above 400? Whoa! Calculate what that amount of electrolytic delivers in a 10 second Jab through your traps...

Nothing. As far as I'm concerned, but it looks good to Gerd's croco world.

To call APD the limiter in any setup for high power and YGE 320 not is an incredible statement when the yge has double the on resistance. So why would you frame a story on RC groups that falsely leads on consumers and modelers that the slowest and highest internal resistance in class inverter delivers more power than the fastest most power dense agnostic inverters on the market. Now why would you do that? The APD is lighter 4x faster and twice as powerful.


Smh.....

"By the way, Plettenberg specifies a realistic 86% eta max for the engine."
~Powercroco~

So I guess that means there is one in runner you found the 24kW 7455 matches in eta. This little ancient one less than 1.4kW from Plettenburg



Come on bruh... I have things to do.

All the numbers from high end in runner manufactures that are comparable in price with scorpions outrunners are realistic and higher in efficiency.

Hi Ralph,
Hopefully your are well fed now from post #3 So from here I can get back to my original plan 8000 views later of sharing what we are doing here in America with the modelers here on hobby squawk without reference to your alias accounts here, fake news on Gerd's Crocoworld, or helifreaks where the moderators are your angrily enlightened customers mad at the messenger. In the last 2 years DZ has spent about 20,000 dollars on your friends planes, with your scorpion thumper powerplants and hadn't hit the mark set by the Pyro 1000 yet. You say there is no difference between the two but the Pyro 1000 is lighter and makes more power than a 5050.So thank you all for your time and patience to let me address this problem of false advertisement with you Ralph. Your silence about it all has been a real pleasure . With this latest typhoon DZ has spent right at $9,000.00 USD in air frames alone and will only have 1 surviving plane out of all of that he's flown 603 unofficially one time one way with your knocker. Two APD's ran him another 2 and half bands. Thats 11,500.00 USD b4 motors. Seriously Ralph....for 1 603 pass so far?

F3S is a helluva hobby. Its really a shame you wont wind him or suggest him something different for all the moneys he's spent

Hargrave Technologies' FOCAL algorithm sets a new standard for sensorless motor drive, optimised for the most demanding UAS applications. FOCAL extends the low-speed efficiency of FOC to the high-RPM performance of trapezoidal drive, with no tuning required.

While FOC can see higher peak efficiencies in a perfectly tuned combination, this is rarely true in real-world missions. Diverse flight profiles, environmental conditions and production variations all reduce the practical efficiency of FOC.

FOCAL has been developed to bridge the gap, constantly adapting to provide industry-leading transient response and optimized efficiency and acoustic signature.

Another level from APD.....🤪

I wonder has anyone else winding motors has looked at the generated bemf of a wound half stator on an oscilloscope. It only points to the idea that dual 3 phase is a better ticket to power density and efficiency. It will match with a six step much better than the old dual layer wye on one inverter. It will reduce the pm and rotor losses significantly. Why anyone would be stuck on a conventional dual layer wye which is more sinus like with a six step drive like BL Heli is beyond me. Some winders simply are not able interpret this chart data.

Crocoworld got you on plan B my boys....😁

Do you see the commutation ripple in the BLDC/BLAC mismatch pairing in the plan B? In ideal setups the motors generated bemf and the commutation technique MATCH!!!! Im truly sorry for those who cannot seem to understand the electronics.

To 9:15 am EST.

Apparently the leader does not understand these latest iron loss coefficients associated with different forms of excitation and the flux waveforms they produce in electrical rotating machines. As you can see from post 625 that even APD( Hargrave) is in the loop on how everything really works with the different forms of commutation. Its my belief that they have the best inverters in hobby currently and also huge contracts with the military not just 20 rc pilots....🙄 If there is something more power dense in hobby the glorified speed pilot with the antiquated 16khz yge 320's and 400's should post it. All I see is more black box memories$ for DZ.

I cant remember the mode I charged these supercaps with the IMAX B6 at 6s but I was able. They have enough capacity to run the esc without the battery so I'm sure they are a good PS compliment... All I have to do is keep them cool.

Thank for your interest. 😁

I soldered the 6.5mm castle connectors directly on the large solder pads of the hybrid capacitors.. Hopefully I can create a clean modular install with different connection options as needed.. Serial or parallel. This can be 4700 uf @ 70 volts or 9400 uf @ 35 volts. Ive shown the light weight already.

Mr Sharp, 😁
This is a video of the electric vtail Simon put together controlled with BL heli FW. He is also an excellent 3D cad/cam modeler.

Check him out.

U auf der Suche nach Aufmerksamkeit, Ralph? Du hast es für einen Beitrag. Laut loslachen. Ich kümmere mich wirklich weniger darum, unsere Motoren zu verstimmen. Aber....

Castle 2028 Innenläufer neu wickeln | RC-Network.de

Es ist wirklich schade, dass der Scorpion-Outrunner der 45er-Serie nie so effizient sein wird wie der 2028er Castle Inrunnner. Große Monodraht-Aufwicklung? schlechte Idee.... 😁.
Viel Glück bei der Untersuchung dessen, was sich im Inneren der USA befindet. Stellen Sie den lauten Außenläufer in einen 50-Zoll-Mono und GPS, wie langsam das Boot ist und wie heiß der Motor ist. Laut loslachen. Diese Granate hat keine Chance, Junge. Ich wünschte, Sie würden es in einem Boot mit 84% ETA betreiben. Der

Der 10-polige Außenläufer würde etwa 2 Kilohert Grundfrequenz sehen. Ein heißer Arschkern
und 7 Prozent weniger Wicklungsfaktor sind nichts zu vergleichen. Ich sehe, dass Sie weiterhin Unwahrheiten in den sozialen Medien verkaufen.

Looks like youre doing a single layer too.


Viel Spaß beim Verstimmen 🙄

Beware of the crocodile.

There is significant difference in performance and power potential between a Scorpion 4550 stator and a 5170 stator in the Castle 2028.


Thats alot of meat for making power. Of course castle is larger and weighs more than the less powerful wunderbar!😜 This is not posted on the German social media but a drag castle runs 60,000 rpm which would deform the bell on the 50 series black and gold speed engines. The 10 pole motor would also see 2 khz in fundamental so you will certainly see elevated core temperatures and frequency driven losses as it compares to a much faster more powerful machine. The 2028's working harmonic of the overlapped winding doesn't beat on the rotor iron and PM's harmonically like the 10 pole does , and it has a 7% higher winding factor. The outrunner also has no hall sense so it cant utilize smart sense with cryo drive technology from the latest castle inverters. If a croc honestly rated his performance he would post the resistance and fill of the large mono wire in the machine. I see alot of unused space as compared to the factory drag winding. The micro wires fills all those voids you see here. 👀

The factory motor also does not use any spacers Ralph. The individual should have scribed the inside of the can before removing the iron core. So when the winding was done you can glue it back in the proper position with bearing retention compound. Loctite 609 bruder. We use it to secure prop shafts on 3.2mm extruded steel wire drives in fast electric boats exceeding 6kW. After the core is glued back in place with the new winding there is a protective gfk disc is inserted before the end bell goes on that protect the winding heads from motor mount screw that are too long.

Goof Troupe proof....

Btw it looks like the winding heads were too big so the stack was shortened and hard to press flat like the factory winding. Why else would you remove or not add back the loose laminations. In the speed scene the Kv is critical to prevent rotor failure at the specified voltage written on side the can. The wires also have to be soldered to the external lugs of the end bell/hall trigger assembly. The castle motors use 8 awg stranded wire externally out to the inverter. So it would be interesting to see the final resistance at the inverter and if the motor ever runs again as its was designed for with the soft factory wires and hall sense working. It goes back to the customer like this so maybe it ends up only an open loop sensor less proposition with additional connectors if he wants the soft external wire back?

Hubert

[Clugh]

If you want to build an inrunner with your resources why not a BLDC with a hammerless CoFe stack? 8,10 pole laminated rotor with spoke pm like the EF1. Then u can utilize the advantage of fill or large strand wire with the FSCW. You can implement the same Kw of 1 with a UETW stator, hybrid winding or flussperren single layer 14 pole machine..




Then you have to run it with an inverter like APD not YGE.
