As far as a a steady state dyno you can just point two identical motors to one another and use an inverter on the load motor in regenerative freewheel mode. You have a totally variable brake for the DUT motor then and can dump the rectified wattage back into a battery, halogen light bulb stack, or large heater core element.

You can aliso turn an eddy current brake on the lathe and CNC router and use old hard drive platens space out on a spindle with a tangential fixture that can traverse an array of neodymium in between the hard drive platters.

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.

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.

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.
