Alternative motor windings and drive schemes

[Clugh]

Look here... this is 9400 uf. In hybrid capacitance. Its going to have a lower resistance. Charge and discharge faster and clearly is alot smaller in footprint...What do people want in a plane a brick or a feather?



I don't expect anyone to get involved in our nonsense but yes people take all the time without a word on one forum then will go on a hobby forum and do not or even discredit you. At this point its funny to me because they are right here currently posted silently waiting for the next drop!

I'm not a lilly the foo foo American.... they can forget that...

A motor with copper wrapped around iron teeth is only part of a exceptional e propulsion system for an airplane. If a person wanted to fly faster why would they run a heavier inverter with a higher on resistance with NO FAIL SAFE... then want to discredit me and what I bring when I beta test and showed them the lightest most power dense inverters in the world.



Its rhetorical

If you good you will have a formidable op. You want one if you are competitive. But when I can get 60 amps continuous and 100 amp peak at 6s in less than a 1/4 gram I have to look the op up because anyone running and inverter with 3 pin d2PAK fets in 2024 is not one.

They not doing nothing...and that's real. It think it takes more than copper wrapped around iron to really beat me.

660 uf in conventional electrolytics Styled like the 3 on a YGE





4700 uf in hybrid SMT electrolytics.

Let the e astronauts study it. It will be okay.

Ralph you know NC was always first in flight anyway...

An ultralight ultra thin and smaller than the hybrid high capacity bank wont use electrolytics or hybrids and If I build a pilot one it would be over 100 dollars in material alone for 2200 uf.

You better believe it!

For my RC sport I'm not going to waste my time with water cooling modifications of a new surface XLX2 controller. I just cop the marine version because it already has that and with the low profile a clean modular installation can also be achieved.

[Clugh]

Anyways.. look at the solder pad on the bank. Its 14mm x approx 7.76mm with thermal vias . Man! that will hold a gob of silver solder. You could even flow the 6.5mm connectors directly if you prefer . The flipside is already potted on the board so these would be easy to liquid cool fully submerged inside an enclosure in just this orientation. Sitting on top a heatsink with a TC adhesive or tape like this example is good. But fully submerged in water is more effective is better.

[Clugh]

This solder im using doesn't have the ideal flux and flow like really good Kester which is preferred. But its not a cold joint. What looks like bare wire is solid as a rock. I flood the pad first then saturate the wire with the iron below and solder above then join the two. Helping hands or welder gloves will help you.

PC🐊... Wussten Sie, dass Castle ein 250-Watt-Eisen für diese großen Lötstellen an den Motoren verwendet? Was ist Ihre?

Good morning.
Its 9:56 am EST and Sunny here in NC the high today will be 82*F the Low 57*F with winds moving south to south west at 10-15 mph.

I see you've set up camp here so...Willkommen in Amerika

Danke,
Hubert

Two 2028 Neumotors....

Großer Erfolg

The Americans are building...

Ich möchte die Debatte anheizenWith Pyro-mania

In less than 4 years....

In the 12N10P Y-D hybrid what we hope for is attenuation of the 1st, 11th, and 13th, harmonics and a boost in the 5th,7th,17th and 19th. This has been shown to significantly reduce iron losses in particular the rotor and pm. This is the first leg of the test wind. It is the inner delta motor. You may count the test turns in 22awg. 👀 "covert ops" can feed themselves....

😀

5 more months to go.

[Clugh]

4 years for a hybrid PC?
Will terminate and run the YYYY-DD hybrid tomorrow.

Pyro-mania

Großer Erfolg

Danke,

Ihr wisst, dass ich es liebe, Debatten anzuheizen!


You can get some sleep now Powercroco. I'll see you first thing in the morning...and don't forget to change your diaper.

Thanks for your time and patience
Hubert

[Clugh]

Good morning..

Großer Erfolg

[Clugh]

We will see if we can crank it tomorrow

Großer Erfolg

U see Ralph 👀

It does not take 4 years to wind a hybrid correctly.


Major Gasoline....

@boho1
Didn't i tell you the 41 series is noisy. When TG ran is with all its screeching in the video it was on a castle XLX2. Well they have tried it and this is what one modeler had to say.

An acquaintance of mine once had it in the Kraken. Unfortunately with an extreme whistling concert.
You can try it. It's certainly not the best engine, but it certainly does its job even when it's quiet.

And it seems the hobbyist were pointed towards the XNOVA instead.
😶

I keep hearing about whistling and that happens at frequencies evenly divided by 3. Around 300 hz fundamental seemed to trigger around 1.7khz a solid tone.... from the asymmetric wye wind brought forth by Duane Hanselman. You all called it the Kabi wind. I scoped it and sent photos to the guy that needs 4 years to wind a hybrid motor so of course nothing came of it. Just more pom poms for "Xhris"

See how the truth comes out? I even analyzed it under load on castle 200 hv pulling an 17X8E apc The UMP of 15 tooth winds will only add to this some repetitive modal anomaly to the stator and thus the gap. Do you want it??? Its the "Soggy Bottom" you are after!

Is another similar asymmetric wind I derived. It has a higher wind factor than a 12 slot 8 pole machine. Kw for 8 pole is .86
