Alternative motor windings and drive schemes

The 2025 1000cc Fireblade s 214 hp with 83 ft/lbs of torque. It is 447 pounds to the curb. This is a bad HIGH REVING machine Chris with a programable suspension alone worth the majority cost of the bike. The rest is space age engine tuning and delivery to the ground management like wheelie control. It is awesome.

Technology has come along way as even my 2024 Suzuki 450 supercross bike has programmable fuel injection and traction control.

What Ive been looking at is the modular high voltage bipolar SicFet and Gan fet modules to team with the mitochondrik with Talega at its heart.

[Clugh]

Of the hobby manufactures It looks like Neu is the only one that offers something suitable because even the pletti NOVA is only 30kW . I think you'd need at least a 100kW to be really golden.

Your nemesis is using the "same old tired playbook...."

Hi,
yes, you are right. Hacker has a few bigger engines but they have the same crap in them as Scorpion, only they are at least cheaper. Lehner simply builds several motors on one shaft or like the Hyperloop drive at the University of Munich, where 8 Lehner internal rotors were coupled. Each delivered 30 KW and the combined 240 KW accelerated the Vaccumracer to 482 km/h. Pretty decent for a student toy. The punk once started building a 40 KW motorcycle engine in his reptile forum. They got the sheets from Scorpion and turned the aluminum parts. At the end all that was left to do was wrap. The punk didn't manage to apply the winding evenly. The stator was so warped that you couldn't finish the motor. The troops completely failed.
You can also buy the Molabo motor with integrated electronics. They easily have 50 KW of continuous power and, depending on the design, can also provide 80-100 KW for acceleration. Or just two machines.
Yes, and the Zubax thing sounds good. What are Wolfspeed's smallest power semiconductors?

I am currently developing special LED arrays that enable better illumination in dental handpieces and turbines with fewer shadows. They work similarly to matrix lights in cars.

I worry about safe assembly with the large PM's if I build one but the 125mm stack could work at the right length.

The hyperloop was just featured on a show here in the US . Its amazing and europe is more advanced than the US when it comes to transportation by a long shot. This isn't a secret we're behind.... We have dinosaurs here that want to keep the inefficient way. But electric is also making more torque so its already over in reality. Gas is dead sooner or later.

Fossil fuel and middle east oil barons are a old & tired playbook for sure. We've been involved with the nonsense and greed too long. No gas bike can touch the Stark varg! not even efi 500cc strokes which have about 20 hp less!!!!

it is significantly faster but has to be driven differently so it will actually take time to really lower track speed because the bike is ALOT to handle for even the factory racers.

All that power can be hazardous if you dont respect it!!!!

Hi Hubert,
Yes, a larger machine presents some challenges that are not entirely without their own. Okon failed with the Powercroco motors, which only survive for a few seconds anyway. And this year again there was no increase. Everything just slowed down. To assemble a large machine that is designed for up to 100 KW of power, you must first make sure that you have a device for inserting the stator into the permanent magnet rotor. We did this on all machines with trapezoidal thread spindles that we moved powered by a cordless drill. The magnet rotor is slowly lowered onto the stator through the spindle. Without such a device, the magnets would wind up the rotor in milliseconds and if fingers or anything got into the air gap they would simply be cut off. The risk of injury is very high. Make and cast the coils cleanly. Cooling and all electrical contacts are manufactured and wired to a high quality. You know the challenge from production at Mercedes and Wolfspeed at the highest level. The hobbyists don't know that at all.
i start today cleaning my lath to prepare the parts for my motor for the speedboat , most carbon parts.

Hi Christian,

This is why post assembly magnetization or the pm-less DC field coil flux switch motor is also attractive for larger traction machines. Im examining the paper you sent me with many different versions.

But a monolithic hub motor swing arm assembly is also an attractive idea.

Great news about the boat motors. There is a good boat section here so visit it and add to the knowledge base from a former world champion in electric boats.

PLEASE!


I also plan to start and finish a few boat threads and finish the 1/8th scratch build but first I have to get some of the winding work out of here so I am sorry I cant talk much right now. I really have to wind these motors. The spy camps here and is looking for my large speed motors. Don't worry they are coming and Petr says the special speedfire2 is a about 4 weeks out.

He will send me some photos I'll share with the goof troupe on crocoworld. If the scorpion kings hangs out in the boat section Ill show him how to liquid cool the windings of a motor directly so he can also copy that from me to prevent all surfboard and traction machine DNF's.

Hi Chris
For fun here is a photo from a real audiosmith.

You know I set up this aperiodic enclosure with 3 12 inch Dayton sound reinforcement drivers in an Acura a few years back. I've been MECP certified and an audiophile car and home for about 35 years.





Thanks

Hello Hubert,
Yes, I remember, you can't remove the rear window with speakers like that. 😂 I chose suitable ball bearings, first of all hybrid bearings, steel rings with ceramic balls and a metal cage. We also designed the bearings in the flywheel accumulators with special thin greases, which have proven to be very effective. With large thin ring bearings, the forces caused by up and down speeds during slight tilting are extreme and destroy the cages if they are not made of high-strength material. Cerobear is top. I may go with all-ceramic for a motor with full water contact and rotating propeller blades like the steel laser-sintered disc propeller; I also have a CFRP version with an outer diameter of the rotor bell.

The three 12 inch drivers on 2000 watts RMS drive at least 145dB of sound pressure. Not enough to knock a back window out. The car has all it's cargo space and access to the spare.

Oh so you're still on the Scorpion King installing 5 dollar bearings in a motor that cost 1000 euros..

Imagine Christian if you can....Dzhamel's $20,000 has all been riding on 10 dollars of insurance and they are all in the ground. True or False?

Rinse and repeat the planes and motors over and over for the $ame black box results and one $peeding ticket over 600kph

Thats Jonestown! and the general offering plate passed around the church is full with DNF refurbs so for them I guess that works.

YGE's RMA request also stays full

Joker 5060 tuning test as a cheap alternative to overpriced brands | RC-Network.de

Wirklich erstaunlich, wie die wirklich klugen Leute dort den idiotischen Experten ständig etwas beibringen müssen. Ihr Verständnis ist so grundlegend, dass es erbärmlich ist, und Thomas braucht mit seinem frechen Mundwerk ein Handbuch.

[Clugh]

Wie auch immer, das Ganze ist ziemlich langweilig und wird dazu führen, dass Scorpio nach einer langen Zeit sowieso besser wird. Ich habe keine Zeit für diesen Unsinn. Ich habe Arbeit zu erledigen. Ich wünsche Ihnen einen schönen Tag.

And isnt it wild that @ only 2000 watt RMS in a car we use 0 gauge cable to the bipolar drives. In audio if you were to steal a DSP chip then you could have auto calibration just like you set up surround sound in a room except you are dealing mostly with the bottom end 500hz down. The esc would literally send out a sample listen with a microphone or piezo device then reconfigure itself for the optimal response. It is a waste of time trying to point out the audio agnostic DSP correlations for a sophisticated inverter to an amateur that thinks he knows it all anyway.

The right FOC inverter can optimize its commutation around the props load. HA! a YGE 320 is nothing by to days standards.

This is Talega at its core! floating point SVC FOC. Thery don't have anything that's even close to being as sophisticated in a YGE and the moron didn't offer any of his props for us to test with the system he wish he had. I'm sorry to inform you but nothing exciting will happen there. They use old antiquated high resistance equipment and just now building a thrust stand and don't even know how to make use of its static thrust data.

Thats why they are not beta testers for ZUBAX or APD!



Have a great rest of your day kiddies...

Ich finde es lustig, Chris, denn der Scorpion King weiß wirklich nichts. Dieser Scheiß ist über 6 Jahre alt. Dieser Mann fährt immer noch einen 320. Schaut euch an, wie sie in den deutschen sozialen Medien über dieses Thema stolpern. Es gibt jetzt Wechselrichter, die das alles können. Seien wir ehrlich. Sie sind in Sachen Antriebstechnik weit hinterher.


I really have to go...

Hi Ralph
I know you are up at 9:36 am in Dresden Germany studying the smart inverter because the YGE 320 is DUMM. So your fans know where class is for you.

Christian,

Da der Angeber ständig Vergleiche anstellt und nie etwas durchzieht, habe ich mir auch noch etwas kupferummantelten Aluminium-Lackdraht zum Wickeln besorgt. Der kommt von einem Transformator aus der Außenwelt. Er ist auch groß. Wahrscheinlich 1,828 mm. Sehr biegsam und leichter. Man kann ihn in der Hand fühlen.

Hi Hubert,
I haven't read the thread on RC Network at all. Yes, they have slowly learned how to wrap an engine. But they know very little about propellers. They don't even have a simple device to at least determine the pitch of the propeller blades over the diameter by measuring the angle from the entry edge to the exit edge. We have something like this at every competition. And they have never done this before, not just simply measuring the angles there, but also measuring the slope separately for each profile segment at the entry edge, in the middle of the profile and at the exit edge. Whether and how large a profile draws a concave line as you can see on the simple protractor, the pressure side of the propeller blade is hollow. This has a lot of influence on how the flow is accelerated. These simple people didn't understand it. I discussed this with Jim in great detail. Lohrin Miller has also written some articles on this, etc. It is essential if you want to achieve more. Of course they don't have to, they're just competing against their own dull material, without any progress. What are you planning to do with that beautiful wire?
Do you think they understood Zubax idiea ? it is the same like the propeller

Hi Hubert,
In the RC Network thread, Sebastian is of course right when he writes that the blade angle is measured at a diameter of 70%, as that is where the greatest thrust can be expected. It is precisely the case that the thrust value, distributed over the propeller circle area, is greatest at 70 - 75% of the diameter and the technicians therefore measure this as the pitch there. It's already in Dubbs' book. It's a shame that you don't even have the backbone to say Sebsatian, yes you're right. They are such embarrassing model makers.
