Alternative motor windings and drive schemes

[Clugh]

Dr Okon's pitiful copy shop failed to realize that I also get my bearings 2 ways. Dry or with a UDL treatment.
UDL Dry Lube by Boca Bearings :: Ceramic Bearing Specialists

[Clugh]

There are also other options for a dry bearing I'm sure the medicine Dr/hobbyist never thought about.

[Clugh]

Firstly the silly man doesn't realize what he purchase is not CUBIC ZIRCONIA it is Zirconia Oxide. Cubic Zirconia is a gemstone that can be man made. We make sapphire and moissanite along with SiC. Ralph doesn't know anything about materials. Secondly the difference between grease and the right oil is as much as 10000

This would be a good bearing that cost 3x and NMB the ABEC is definitely not 9

[Clugh]

He doesn't know anything about what he purchased so the result of whatever non controlled test he runs is subject to varying results. like I say he is a funny amateur. These are ABEC 5 so I supposed since he went and grabbed ABEC 9 he knows wtf he is doing??? I already told him its more to consider than ABEC rating 6 years ago. So if he went a purchased some Chinese trash packed with grease and ABEC 9 stamped on the side for his friends trying to compete with what we do here that's on him. If the bearing acts up or seizes you can fry your inverter.....

Oh no sir. They are going to have a "cubic zirconia bearing" installed by you. PLUS if they subscribed to your racial epithet like "you dont feed black trolls" they wont get anything done here!!!


They and you are sadly mistaken cap. I can be an American black nationalist too since you're into that type of exclusion.

Long as you know I can TAKE ya little rewinding business from you just like that!

That's no cap.... i don't deal with small minded individuals into bs like that. My friends range the globe.



Thanks
Hubert

[Clugh]

SO.... If that man wants to send his 5040 here to avoid fake diamonds being installed in his azz by RalphSS he can. It would be his first step in the right direction.

[Clugh]

You have too much business Ralph? is that why this photo of all the engines you rewound in the post about the cubic zirconia bearing about 6 years old?



get some rest pal....and stop perpin' you still hadn't sold em all... at 600 euro a piece

[Clugh]

And when are you going to find the gravatas to post here directly POWERCROCO or are you truly that much of a wierdo? Having to drag your remote reposes BACK across the Atlantic so It doesn't look like Im talking to myself is time consuming. Its time you get potty trained son.

I'm sure your friends in Germany are tired of listening to you make post out of context in their forum about me since I'm actually not there. That type of behavior lends itself to needing some type of cognitive behavioral therapy.

Let's get it together....you are here on this forum.

Wenn du dich um deine Angelegenheiten kümmerst und aufhörst zu berichten, was hier vor sich geht, du eifersüchtiger Bastard, kannst du dein Geschäft retten



Danke,
Hubert

Since the silly man is still responding remotely even though he's here I won't dignify it anymore. This guy is truly a nut and will probably lose all his pilots soon enough. I'm sure they are beginning to see how goofy he is and how little he actually knows. He reminds me of a few of the hobbyist clowns I left on helifreaks . Of course He's back to NMB without a test. You all can stop wasting your time with this dingle berry and all his editorial on the German socail media. It's truly bs. He is nothing but a waste of your time. Hes going to keep delivering the 69% toast to his friends in 2025. U stay with him if you think motor winding hasnt progressed in 20 years...



A total mistake that has to go back and edit out "cubic zirconia balls" they guy has not a clue. ZrO₂ is vastly different from SiC or other ball materials it in fact has a LOW thermal conductivity and is also naturally occurring. SiC on the other hand was only seen on meteorites from Outerspace until the pair of engineers NC State created it on earth . Thats CREE, and like I said this is not Power Croco's element. You can liken his editorials to incoherent babbling.

[Clugh]

You know the ignorance you are typing on the German forum. I wont waste my time copying and pasting the bs here. Mr Cubic Zirconia..

I was hoping to see your full "cubic zirconia" ABEC 9 wunderbearing actually run....



Pinocchio as usual...... the 20 pole or ABEC 9 never happens to run despite all the typing taking place...

[Clugh]

Haters are going to hate. That's just part of life. These 3 P600s are ready for their final turns. Ill pot them, terminate them, record constants. and they are out.
You see the axial tie in for the three ceramic hybrid bearings in the attachment. I have two more to do currently and an AJ 650 for F3A. Then we are back to my Hybrids R&D.

[Clugh]

This will be a P800 6+11 hybrid in 17 &15 AWG mixed.

[Clugh]

This will be a HK5020 5+9 hybrid in 1.828mm

[Clugh]

WOW!!!Look what the REAL engineer on the German social media has done. Like I said when he set his mind to it Christian sets things up nicely.

"Hi,


something about stator design and why the old hammerhead sheet metal cuts in the high-performance range are no longer up to date and the iron is so important.
What is the sheet metal cut in the electric motor supposed to do? It is intended to convert the energy used into a rotary thrust and thus the engine torque as efficiently as possible. First of all, you should be aware of what the magnetic force promotes and why. One is the material used for the sheet metal and the other is the geometry. The geometry is how big is the coil and if it is provided with a core, how big is the core. Quite simply, the more iron in the core, the greater the magnetic force that can be achieved with the material. This works well with coils with an iron core until the field brings the iron into saturation. Then it is no longer possible for the time being, an increase in the coil field does not cause a further increase in the magnetic force. The increasing effect of the iron core thus limits the magnetic force and, in the electric motor, the rotational thrust. If you look at two motors, one with a 5x25 mm iron core and one with a 3x25mm iron core, there are even effects that allow the thicker core to generate even higher rotational thrust. The thin stator tooth can only generate 40-50% of the torque, which is of course awesome. An engine with the thicker Statoor tooth can therefore be a lot smaller or The one with the thinner stator tooth has to be designed much larger to achieve the same values. From a motor calculator
:
Since it is the stator of an electric motor, reducing the stator tooth width from 5 mm to 3 mm affects the magnetic force through the following effects:

1. Reduction in magnetic cross-section

The magnetic flux density is defined
as follows, where is the magnetic flux and the cross-section of the tooth surface.

If you reduce the width of the teeth from 5 mm to 3 mm, the cross-section of the magnetic path decreases by 40%. This means that the flow per area increases, which can lead to the saturation of the iron.

2. Increased magnetic saturation:

Iron has a limited capacity to conduct magnetic flux.

• With 5 mm wide teeth, the iron can conduct the magnetic flux well.

• For 3 mm wide teeth, the same flow must flow through a smaller area, which saturates the iron faster.

• At saturation, the magnetic resistance increases sharply, which means that the effective magnetic flux through the motor decreases.

3. Influence on the magnetic force

The magnetic attraction is proportional to the square root of the flux density and directly affects the torque of the motor:

As the narrowing of the teeth increases the magnetic resistance and the flow decreases, the resulting torque of the motor also decreases.

Quantitative estimation

• If the magnetic resistance increases by about 40-50% due to the narrower teeth, the magnetic flux density could decrease by about 20-30% as a first approximation (depending on the permeability of the iron and saturation).effects).

• Since the magnetic force is proportional to , the resulting magnetic attraction (and therefore the torque) could decrease by about 40-50%.

Conclusion:
Reducing the stator tooth width from 5mm to 3mm reduces the magnetic force significantly, probably by 40-50%, depending on how much the iron saturates. This can significantly reduce the power of the engine, especially the maximum torque available.

Then there is the question of hammer head or open stator grooves.


When high power density and smooth engine running are paramount, hammer heads with almost closed grooves are better as they smooth the air gap field and reduce iron losses.

If simpler coil fabrication with the highest copper fill factor and highest rotational thrust is desired, open grooves are better especially for single-tooth coils and high-current applications.

Simply calculate the stator surface times the lever arm and use 50% for the stator with the thinner 3mm stator tooth for the rotational thrust, which it can achieve compared to a stator with a stator tooth width of 5mm. You can immediately see that the smaller stator easily generates more torque. With flux-enhancing magnet systems as well as such, since the thinner stator tooth cannot carry the flow at all. That's just physics.

If no stator with iron is used, i.e. air coils, a few limits are practically completely eliminated. There is no saturation of iron. The entire winding room is filled with copper and with extreme magnetic systems even very high fields can be generated with up to 5 Tesla by modified Hallbach arrays ect. . The best way to see this is with coil guns, which achieve extremely high field strengths and shear densities that would not be possible with iron."

Happy Amps Christian

This was worth dragging here. Excellent post!!!

Keep up the good work and avoid haters at all cost. A real waste of time. Really cool what you did there. Hope to hear more about it.

I see you're on track to real innovation in motor design.

Schau dir nur den Salamander an, der Christian den Daumen hoch gibt, nachdem er ihm erklärt hat, dass wir spezielle Formeln für Effizienz haben. Was für ein Clown! Du bist der Einzige, der da steht – mit nichts außer einem YY-Wind, so alt wie die Erde, einem entmagnetisierten Rotor und einem einfachen Stahlkugellager im Jahr 2025.

[Clugh]

Du bist erbärmlich, Ralph. Wirklich. „Spezielle Effizienzformeln.“ Du solltest endlich die Klappe halten. Du stehst vor deinen Freunden wie ein Idiot da, wenn du über Kugellager redest und keine Ahnung hast. Nur wenn du ihnen die gleiche Wicklung und Geometrie gibst, werden du und sie die Ergebnisse kennen. Was zum Teufel ist ein Experte darin?

[Clugh]

Now the most important question Its the same thing as the 20 pole. Does it run???

Then what are the recorded constants. No matter what's created those questions will always apply. After that is answered the forum can really get excited about it. Still photos are on thing but it must run and make good data to be truly considered an improvement.


Then put them into Holle's calculator.

To see if its really the bomb....

It looks to have promise although most Halbach arrays ive seen don't bring back the elevated performance you always hear about. Its a100% magnet coverage so it contradicts some of what you said earlier about the 20 pole.

Thanks for explanations
Hubert
