I showed you 2 in 2020!!!!

And i showed you the multicopter package THEN with two motors totaling around 300 grams

Hi Christian
"Wye" bother? You may take inline tandems of any brand and wind the rear a SL wye open ended coils and the front a SL delta. Just wind the motors for the same Kv and run one controller. Easy

The DG&DG half turns may work really great to match them more precisely and attenuate more.

With forward thinking If I really wanted air to go through it I can use a 32mm spinner and leave the rest to radiate. Besides we could counteract heat cryogenically with my artic blast. "Renec" has already seen my test and other cooling concepts. They've yet to evolve to this level of thinking The Intelligent winders there in Germany and internationally could also wind the tandem wye-wye and so on thus many electrical gearing, winding, and connection options between the two would be possible. The 24N22P Neu 4610 multi-copter ports seen here are 130 grams and 1.5 kW a piece OEM. I could do a lot with them. The shafts are 6mm. Poor Kunipatz there is no need to quarrel. Better minds working and all this can be done with any brand. The NC State D.E.E.C.S./ABB Dr.Sariful Islam team winding proposal brings a 94% reduction in pm losses without segmentation on their tested 24N14P prototype. I feel fairly confident at just the eye test that this or anything remotely close will result in the cooler can under full load. I'll buy an IR gun today so we can test it. The photos "are of nothing" but they want more right.....




Happy Harmonics,

I didn't remember but it says there 3000 watts direct drive deliver at only around 260 grams in tandem.


How much does your weight with the mighty black and gold?




Tragic...

Looks like Luke was explaining something similar to you in legos here. Maybe you should rethink your alliance.

U REMEMBER RALPH

Hi Ralph,
so ist es halt ein ganz normaler Gegenläufer Antrieb der nichts Inovatives hat. Gibt es auch zu Kaufen.
Ich baue gerade auch einen Gegenläufer Antrieb für einen Freund . Dabei braucht es nur einen Motor , da der beide Propeller per Reaktion versorgt.
Heist 1. Propeller an der Glocke und 2. Propeller am Statorhalter. Regler im Motor integriert. Alles Drehbar mit zwei Schleifkontakten , einer im Drehzentrum mit quasi null Moment , der zweite mit kleinem Radius drum herum. Reglersignel per miniempfänger neben dem Motorsteller , heben aber auch eine micro Bluetooth Koppelung in Arbeit oder ganz einfach ein dritter dünner Schleifring nur für das Signal. Der Zweite Motor entfällt völlig , die Leistung bleibt gleich da durch den Gegenlauf doppelte Drehzahl anliegt , halbe Windungsanzahlt doppelte Drahtstärke und erheblich Leichter.
Und für den Kuni. Jeder Gegenläufer Antrieb hat immer einen höheren Wirkungsgrad da Sturz und Zug entfallen was allein schon den Wirkungsgrad erhöht.

Hi Ralph,
So it's just a completely normal counter-rotating drive that doesn't have anything innovative. Also available to buy.I'm currently building a counter rotor drive for a friend. Only one motor is needed, as it supplies both propellers via reaction. Heist 1. Propeller on the bell and 2. Propeller on the stator holder. Controller integrated in the engine. Everything can be rotated with two sliding contacts, one in the center of rotation with virtually zero moment, the second with a small radius around it. Control signal via mini receiver next to the motor controller, but also a micro Bluetooth connection is in progress or simply a third thin slip ring just for the signal. The second motor is completely eliminated, the performance remains the same because the counter-rotation results in twice the speed, half the number of turns, twice the wire thickness and considerably lighter.And for the Kuni. Every counter-rotating drive always has a higher efficiency because camber and pull are eliminated, which alone increases the efficiency.

Brenner is on his 4th series of production.. but you hard head,,,,

Imma talk to you later because according to you 2 I haven't shown either of you anything innovative or that can match what you do over there.

But you know already that two scorpion 4020 hks in tandem b4 mechanics, props, spinners, or anything will weigh over 650 grams😳 and that this 601 gram 7 to 1 reactionary gear drive that cost 1700.00 USD is not Legos right???

3+4 7 ---- 372 743 643
4+4 8 ---- 325 650 562

Hi Ralph
Here is another answer towards the yge 320 inverter.

If a trap algorithm is not more efficient at highspeed than a sinus. Why does Hargrave(APD) use it vs FOCAL algorithm for highspeed? In their latest and greatest. it also does 64Khz Where is YGE Ralph?? 🙈🙉🙊

U also know now that Neumotors USA is the OFFICIAL distributor... Our "anglophile" drive from Australia is much more sophisticated than the old HEAVY German jukebox u push.. Scorpion support should be running their 6 step Tribunus..😀

This is also in my FE boat thread but I want to make sure people interested see it. I got 2 of these hybrid caps because I intend to liquid cool them in a power system for a fast electric boat, and their aluminum body with no heat shrink facilitates that. In series they supply 4700uf @ 70 volts. In parallel they supply 9400uf @ 35 volts.

[Clugh]

Did you know that

Amps = Farads x voltage/time (seconds)

So its very easy to see mathematically how a Farad amp delivery compares to a microfarad and how extremely short discharge times translate to large amperages. A dead short is instantaneous so its very easy to see how much current is in a moment like that.

@Ralph

BTW there is already a hydro version but hobbyist are adding liquid cooling to the standard castle Xl and XLX2 esc's. The XLX2 from Kansas peaks well over 500 amperes Dorothy.

I’m a bit confused… Every post in this thread is by one person, Clugh. Yet Clugh seems to be responding to other posters. ???

I'm also a bit confused. You talk about Clugh in the third person, so who are you asking if Clugh is the only one responding in this thread?

@ Ralph
I figured If I made my attachments thumbnails your friends and those with real interest would have to join.


Guess that worked....

BTW
Bert Dekker is the best most thorough hobby motor hand winder in Germany & DWN is at 103K

Now its 103,002 Ralph

Nothing comes here for you or your friends from Brenner drives R&D but I can tell you none of the WC contra drives I'm looking at are made by anyone on the GSM.

Its just more "anglophile" manufacturing💪

None of it is made there, so you probably wouldn't like it or understand it if I showed it to you anyway. If you'd like a tangible close up they sell for $1700.00 - $2000.00 usd. Firm!


No directions from LEGO...

Working on power systems for the boats...👀

[Clugh]

I want to water cool these capacitors. The other squirrels will have to join to see more photos. 🙈 These are 1 Farad at 6s lipo I haven't been able to source these specific super capacitors yet but they don't like to be over 70C! it may be an issue because they are already potted and I doubt the material has a high thermal conductivity because it is crystal clear. There are some clears but I rarely see one much over 1.2-1.8 watts per meter kelvin. If you are a member of hobby squawk you can click on the attachment and see why being potted in such a material would hinder optimizing heat transfer of the capacitors bottom mounted to a cooling block. At a onderdonk moment @ 32msec mark 1 farad at 22.2 volts should be capable of 693 amperes of delivery. If it were 3 farads then you could multiply the amperage that many times !!

Lets wire it up and charge it...


and....

BOOM!!

[Clugh]

I found CDA. I think they make these caps and it looks like you may be able to get you hands on super caps from them that can stand 85C.

Cylindrical - CDA (cda-cap.com)

These are in smaller capacities but very interesting for liquid cooled cap bank

CST Series - CDA (cda-cap.com)
