Alternative motor windings and drive schemes

[Clugh]

I guess also you misunderstood his rectangular coils. What he suggested is that his company made piece wise coils by manufacturing a prefabricated pre insulated modular coil piece that could be stacked helically by building the helical coil layer by layer by welding the prefabricated modules together. If you are silly enough to sit there and paint the wire then you could build the coil with thick mil aluminum or copper tape with solder and the insulating varnish. That really time consuming , like trying to help you, but so is painting pink bs on the wire. At least this would deliver something worthwhile. I guess you do not understand how to enable or execute these ideas given to you eons ago. You are floundering around like a halibut wasting valuable time with your life.

[Clugh]

To wind an aluminum coil and optimize it for high power density you would run it in a flat helical format in the parallel slot. Apparently you misunderstood Luke and what to do with the coils. What he tried to tell you as you wind the coil on a mandrel the press it in a billet former designed appropriately for expansion. The nice paper he offered you gave details on the manufacture of the mandrels and specifics on how much you could press the wire before the insulation failed. What he suggested to you is you could do it at home. You perverted everything and made a mess with pink paint on hobby lobby jewelry wire versus CCA. The pure aluminum needed to the anodized in aluminum oxide not pink bull s hit. You contract a wire haus to get that done. You mess up the execution of every good Idea we have given you.

Pressing the wire is how you get the space the aluminum needs to equal copper back and still get more turns and the lighter motor at the same time.


You hard headed bruh....

SEHEN! Eine verrückte Ratte rennt herum und sucht nach Käse. Ich schätze, das ist ein klassischer Fall von Borderline-Persönlichkeitsstörung.

Insbesondere die histrionische Persönlichkeitsstörung lässt sich recht klar beschreiben.

Es ist dramatisch und bringt starke Meinungen zum Ausdruck, allerdings mit wenigen Fakten oder Details zur Untermauerung dieser Meinungen. Bruder, das muss überprüft werden.

Danke für die Schachtel Schmeicheleien.

was für eine Hommage.


Danke,

See the 500 micron precision ground shims? You want to stay off the shields.

That's only half a mm but the precision ground shim is going to give you a set incremental increase in clearance if you need that. The idea is to remove drag obviously and lower idle currents.

[Clugh]

Another one out the door. A 9 turn 14 pole pyro 600 for a Brenner contra drive V4.

If you don't build the motors the correct way with 3 upgraded bearings that have been specially coated then lubricated 2 stock steel bearings wont last long in the planetary coaxial contra drive and you can end up with a locked rotor in your beautiful bi-planes.

Don't do it!


I have 4 more of these to do and then a P650.

Thank you for your time and patience,
Hubert

Hi the SpeedyBee F7 V3 50A Stack F722 Flight Control BL32 50A 4in1 ESC3~6S stack is on the way. It truly wasn't that easy to come by. Alot of vendors were out of stock.

[Clugh]

Bevor ich gehe, möchte ich Ihnen eine Frage stellen, die Sie den ganzen Tag beschäftigen könnte, Herr Doktor.
Wo ist Ihr Motor mit der Aluminiumspule? Wir sehen ihn nirgends?

Thnx,
Hubert

[Clugh]

BTW

Es ist schön, Alois wieder im Forum aktiv zu sehen. Vielleicht können er und Christian die Sache umkehren und den Fokus wieder auf Wissenschaft und technisches Know-how richten, statt auf rosa Krokodile.

Diese Leute müssen ständig in den Foren aktiv sein, um den Unsinn abzuschwächen.

I also told you long ago if the resistance of the motor is indeed lower than the inverter you may run into impedance matching issues but again you do not listen and are very hard headed Ralph Okon.

Please enjoy the German social media because currently there is no technical value in the motor section of rc-network.de aka crocoworld!

Thanks,
Hugh

Der Syncloss am Brushlessmotor - möglichst reines Wicklungsthema! | RC-Network.de

STARTED IN 2022. THAT'S 4 YEARS OF REVOLVING NONSENSE IN CROCOWORLD RALPH !

See the value of modern vehicles?

Even though I told you about the PWM and low inductance 6 years ago.

[Clugh]

"The video, "How to FIX Desyncs in 5 Minutes," provides a practical, quick guide on adjusting BLHeli settings like Rampup Power and Demag Compensation, which are often the first steps in troubleshooting desyncs in hobby ESCs"

~Gemini~

while crocoworld struggles with understanding this at your direction Dr. making false claims on the forums....

I guess there is value in AI for the hobbyist sake!!!

[Clugh]

"Desync is one of the most common issues with FPV drones, and this guide provides a comprehensive overview of the causes and solutions. The steps outlined here should help you effectively address desync problems with your setup."...
~AI~

Do you see that eve AI knows drone motors desync just like the rest. It's the inverter control that makes the difference. Like your 40,000 rpm 10 pole 3225 turning is 250 Erpm and that is at the limit of a yge's commutation speed capability. 7 Kilo fundamental also generate alot of electrical noise but Croco world is too advanced for a slot wedge.

So Its likely user error if its not the raggedy inverter you use for the setup.

Get in the game bruder!

AI how to you adjust a speed control for desynchronization in bldc motor?

"how to adjust a speed control for desynchronization in bldc motor

To adjust the speed control for desynchronization in a BLDC motor, you can use the following methods:

• PWM Control: Adjust the pulse width of the PWM signal to control the speed and torque of the BLDC motor. This method allows for precise speed control with minimal power loss.
  
  1
• Voltage Regulation: Change the voltage supplied to the motor's winding to control the speed and torque. This method is effective for controlling the speed of the brushless motor and makes it more energy-efficient.
  
  1
• Sensor Feedback: Use sensor feedback to detect the rotor position and optimize commutation timing. This is crucial for applications where jerky movements are unacceptable, such as in robotic arms or MRI machines.
  
  1
• PID Loops: Implement PID loops for load variations, which can help in maintaining consistent speed across different load conditions.
  
  1
  These methods can be applied in various industries, including robotics, aerospace, and automotive, to ensure high precision and stability in motor control.

You see that Md.? At least AI knows what engineers know.

Hallo Dr.,

Ich sehe dich oben auf der Besucherseite. Du hast gestern den ganzen Tag gezeltet.

Es ist seltsam, dass sie glauben, mit deinem 3225 500 km/h fliegen zu können, während du im Syncloss-Thread behauptest, dass fast keiner deiner Motoren, selbst die großen, tatsächlich schneller als 575 km/h fliegt. Wie kann es dann sein, dass ein 3225 in einem anderen Thread im selben Forum fast so schnell fliegen kann wie ein 5050?






Thomas hat auch nicht ganz recht, warum Syncloss bei einem Drohnenmotor später auftritt. Er betreibt den Koptermotor nicht mit YGE, sondern mit einem Drohnen-Inverter, der deutlich mehr PWM liefern kann. Eine Erhöhung der PWM kann den Syncloss-Strom erhöhen. Viele Drohnen-Inverter können die zehnfache PWM liefern als der YGE, den du mit dem großen Motor verwendest. Syncloss tritt mit einem leistungsstärkeren Inverter später auf.

Und noch einmal: Der Schrittverlust könnte einfach daran liegen, dass du dem Motor zu viel Drehmoment abverlangst. Ein kleinerer Luftspalt ist bei einem langen Motor mit nur zwei billigen Lagern aus Thailand keine gute Idee.

Alle Geschwindigkeitsangaben von dir, aber kein Fahrtmesser in Sicht.

Hi,
I have a full set of 7X15E/P and 7X11E/P APC's for the drone plus another singular propeller of each for airplane projects on the way from APC direct. I'm still waiting for the torque cradle sensor, but I can get my hand on the I2C based hall trigger for the tach. I need to 3dp spacers to go between each EV cell so the Lexus EV buss bars and everything lines up nice and neat. A bench that truly takes accurate mechanical power measure is the most valuable tool I could ever have to know the real power and efficiency of a demigod motor .

[Clugh]

Anyone that wants to pm me privately to ask questions about anything they see here in motors and controls or a project they have feel free. We can always build something in private.

[Clugh]

This Clugh F3A Pyro 600 wound with 240C* wire is 1.08 mm in diameter Dr Okon and if they want to strap a 7 x 15 APC to it on 12s lipo they may but Ill be damned if tell a hobbyist on social media they will get any more than 5Kw usable out of it!

I have the propellers and can remanufacture them in carbon fiber if they think they can fly 500 km/h with it.

Electromagnetic Properties of Carbon Fiber


👁 Reads: 2444

Carbon fiber has been praised for its incredible strength, and low density coupled with flexibility, so it is one of those materials that are highly sought by many industries. However, its electromagnetic properties are equally as impressive and carry substantial implications for many uses. In this article, we will be describing the electromagnetic properties of carbon fiber, analyzing what sets it apart from other materials and what can be expected of it in the future. The Basics of Carbon Fiber


Carbon fiber is a very thin, strong crystalline thread of carbon atoms bonded together. These fibers with diameters of 5-10 micrometers are packed and twisted together to form threads that can be used to fabricate a fabric or impregnate a polymer matrix and be used in composites. Thus, the carbon fiber products obtained – carbon fiber fabric, carbon fiber rods and other custom carbon fiber products – demonstrate high strength indicators and low density. The peculiarities of carbon fiber products are due to the nature of the carbon atom. Its crystalline structure is somewhat like graphite and the carbon atoms are orderly arrayed, which make it conductive and possessing other electromagnetic properties. Electromagnetic Properties of Carbon Fiber


Carbon fiber exhibits several key electromagnetic properties that make it valuable across various industries. Let's explore these properties in detail:

1. Electrical Conductivity

Carbon fiber can conduct electricity because electrons are able to reely within the aligned carbon molecules. This characteristic makes it very useful in absorbing the static electricity charges, reducing risks of damaging sensitive electronic parts. Moreover, due to its electrical conductivity carbon fiber is useful in passing as a shield against electromagnetic interference (EMI). Examples include prepreg carbon fiber tubes, carbon fiber rods and carbon fiber sheets which offer high EMI shielding used in electronic housings to enhance the performance of several electronic systems.

2. Thermal Conductivity

Carbon fiber also has the benefit of conducting heat energy, which makes it useful in situations where heat control is necessary. Carbon fiber rods and sheets are incorporated in electrical and electronics devices where they work as heat sinks that help to regulate and dispel heat. Prepreg carbon fiber tubes are used in aerospace parts, satellites, and other products that must effectively expel heat to prevent damage, thus, meeting the standards of the industry.

3. Dielectric Constant

The ability of an element to conduct electric charge in an electric field is measured by its dielectric constant. Since carbon fiber lacks a high dielectric constant, it cannot hold appreciable electrical charge. This property is very essential in cases where the applications involve handling of high frequency electromagnetic waves, since such materials which have low dielectric constant are ideal for use as they do not cause a lot of signal loss or interference. For example, carbon fiber in aerospace engineering in the construction of radomes that need to have low signal loss.

4. Magnetic Properties

This phrase explains the extent to which a material may continue to retain a magnetic field within it. Because carbon fiber is non-magnetic, it has a low magnetic permeability. This characteristic makes carbon fiber suitable for application in areas where there is need to minimize magnetic interferences. For example, in medical equipment like MRI machines, components made from non-magnetic materials like carbon fiber rods and prepreg carbon fiber tubes are used to minimize the magnetic interference and improve the imaging process.

5. Reflectivity and Absorption

The composite material and surface polish affect carbon fiber's absorption and reflectivity. This ability of carbon fiber to both transmit and absorb certain electromagnetic waves makes it an excellent material for radar absorption and stealth technology. Its composite design thus has a likelihood to regulate its ability to absorb electromagnetic radiation, which is beneficial to the aerospace and defense industries.

BUT HE CAN GO AHEAD WITH THE PINK PAINT AND THEY CAN LOVE HIM FOR IT.

I have to go wind for F3A...

Bye Bye...

[Clugh]

AND then......what composite craft modeler does not know carbon fiber blocks high frequency signals from their radio? The Dr doesn't have time to slide 12 pieces of CF sheet 2ooo -3ooo um thick cut in small strips in the motors to close the slot opening to see what happens but has time to paint bells and arts and craft pure aluminum wires pink that he know does nothing but add weight to the machines? Make it make sense....fellas. You will never see this PURE aluminum wound engine realized.....

In particular he has ruined the technical sections of the motor forums in America as far as I'm professionally concerned. He is not a professional in the field of electronics and that's fact.

We have a tendency to become idolaters of an individual because of a trophy they won years ago with 20 competitors present in the entire world versus ask them the right technical questions on a technically based motor forum. We will even go as far as to punish individuals that ask the hard questions VENDORS do not want to answer. Some MODS where bribed with a motor for a plane or helicopter, or simply site sponsor$hip!!!

Obviously the few modelers there on the German social media have fallen into this horrible trap.

Dr Okon does them a real disservice for ever flying any faster.

Thank you for your time and patience,
Hubert
