Alternative motor windings and drive schemes

You can also use a hollow shaft filled with ferrofluid. The work is already proven to increase efficiency and torque delivery of dc machines. Quite naturally a ceramic ball is non conductive. So you could build or by a full compliment deep groove radial bearing with no cage.

Ok...now I have things to do.

Go design a carbon fiber brush grounding system for the shaft. I know you don't know a thing about it.....

Refurbishing.....Hmm

So I went ahead and refurbished the Align and I'm not done yet, but it got silver filled castle 6.5 connectors and water cooling to the 5 milliohm winding directly! Its ready to go into one of my scale boats now....after some good hybrid bearings in it.



Thanks for your time and patience,
Hubert

As flexible as the copper refrigerant line is this could also be done underneath the hood. It is so simple... I hope the Crocodile Dr. can understand.

[Clugh]

But remember . Its alot easier to cool the UVW cables, core, and motor windings than it is the rotor and magnets...Please remember this was a quick retrofit. If I wound from the ground with this in mind it would be much more compact and flow more . With this you take water line a loop one side to the other the water flows in through and out.

[Clugh]

Im also going to put a clean Cobra 8mm shaft in it. I ordered a couple of these and some 6mm as well.

[Clugh]

Ill revise this tomorrow when I have time but now that think about with all the opening in the Align's end bell I can glue a complete cooling coil in directly on the winding heads and it be under the hood clean with the inlet and outlet in the same place and you wont have to worry about electrically insulating it from wandering hands.

I know the Doc will be locked in to see it....👀

Have a good nights rest reptilian ..

Danke,

MR688C-2OS #7 AF2

Align 700 MX ABEC 7
$33.89 to my door for the pair. I searched for an EMQ bearing in the size but haven't found one yet. EMQ is what you'd find in a CNC milling machine. You might pay 150 dollars for 1. Its actually and ABEC 5 ceramic ball but the clearance is different.




Thanks for your time and patience,
Hubert


Edit..... I ordered two pairs since the big cobra takes 2 the same size and the a bigger one on the end ball.

Its plenty of room to run a coolant line in a banjo routing under the hood with the inlet and outlet exiting at the openings above and below UVW. You can glue it into position on top the winding heads with a thermally conductive gel that can take cryogenic shock and has a high thermal conductivity. You probably could make you own with high temp epoxy and powdered graphite. You could vacuum pot it if you are set up for that. All you really need is a 3dp VIP chamber and a vacuum pump. there's been alot to say About my old LRK YY 700MX superpower Align in 1.828mm. Its best to run it for the editors there and once again put it in Holle's calculator. If I put in in video then I can let the keyboards go on about the 50 dollar swap meet motor that knocked Dr Okon's scorpion 4225 by alot. The motor is also only 448.8 grams the 4035 and 41LMT weigh over 482 grams of the shelf.

The two lap record with an ounce heavier 4035 800Kv is 46 mph and a 25 second run so I think the motor has plenty in reserve. The point will be can you drive it and keep in on the water versus it becoming a kite.... They are hydroplanes and can fly just like a Chicken!!!!

Look at the 700MX Black Karma Aligns in SPUDZ fast electric boat calculator again.....👀

The leader wont put his machines in a solid comparative tool but loves to type about me on the GSM......👿
Tata...

[Clugh]

Dr Okon and his friends can draw a vertical line at x=158 amperes. The motor can peak about 13Kw around 269 amperes.

Now I need to finish ordering supplies and finish the other P650 for the TDR's

I'm actually going to put the extra set of orange seals in a Scorpion or Pyro I have here. I step away into these for the 3 bearing Cobra The ultra seal Ceramic hybrid ABEC 7 is still a frictionless non contact that's "Maintenance free" and packed with Kluber L55 grease. They need a break in period and are good for 57,000 if you go with the Shell AF2 oil versions. They are good for 68,000 rpm. No one has to do this but its what im doing for my own motors in my models.


Thank you,
Hubert

If you really want to go high level and high speed with full electrical isolation then you might Go with this fine piece of German Engineering.
A full compliment cageless Hybrid. This is where high speed lies. These can go in a real turbine. Ok???



Now I can put it in the cobra at 161.00 for 1 . It will last forever and the built motor will still cost less than a High end scorpion with 5 dollar bearing rebuilt by Ralph.

But what he needed to do is check his own crap because it doesn't run this well and weighs 30 grams more.

Check my ass... he wont put his in there. An intelligent poster would realize that factual accuracy or inaccuracies of a said calculator would apply to every engine put in so as a comparative tool the garbage you bring up is absolutely irrelevant. Your idle current was 10 amperes so You better check yourself and your ac losses and stop hating on other winders when you have all the burnt YGE toast on the kitchen counter top. Nice thing is I measured it for you and Lucas and showed you photos after your editorials. I guess that why you've been stalking me in cyberspace ever since....? Youve have much more loss in a bifilar winding and an unbalanced Delta with a rotor that fails. I understand by your off topic critique are just a hater at anyone that exceeds you. Ie.. Christian, Thomas, Dekker, Modisc...

Put the recorded constants of the engines of your drive calc or calculator of your choice and lose the same way. You are not very bright if you and the German social media don't realize a constants based calculator is never going to put you ahead with the addition of those variable you find critical for a comparison between two machines.




boy bye...Industry uses the measured motor constants . I use them in Makus Ecalc which is the best online. Industry uses it.

you are the one at 69% eta my Knocker

Hallo Okon, Du weißt auch, dass Max' Flugzeug niemals 550 km/h schnell fliegen wird. Was du in den Ring geworfen hast, entspricht nicht der Realität, da du keine erwartete Stromaufnahme angibst. Warum spekulieren? Gib es einfach in den Fahrrechner ein, wenn du willst, und zeig den Foren, wie viel besser es ist als alle anderen.

[Clugh]

"Only 75% speed stiffness, tribute for the low spec. RPM, he will certainly get very warm in the long run, actually a case for a superchief.
But that was also my experience with the 4530 14P bell that you had sent me back then, the Scorpion obviously doesn't have that much experience with 14 poles. The controller of the Heli Sheikh probably had a lot to do to keep the speed."
~Audi0smith~

So for $600.00 before shipping to my door for 75% empirical I wont touch it but you want speak remotely on winding programs and idle current measurement here in the states?

Your 5050 is at 69% empirical if accuracy is what you are after. There it is....

We could get into a conversation about its curved magnets that increase flux but also increase the sub harmonic and elevated rotor losses compared to flat magnets, but I'll save that lesson for the day you post something silly that touches on that subject matter. Modisc told you you could put scorpion the bell on a 41mm cobra's core and shorten the air gap length significantly. You told him no the steel would expand and strike. His response was he has examined several operational motors with an air gap as short with no issues.

Basically he caught the jealous Pinocchio again. Just like the LMT makes more torque than the scorpion. That was calculated here for you by me Dr Okon, because in 2 years there was no answer to the question asked about it from you or any other leaders there.



Thanks for your continued interest here in what we do and our motors.
