Alternative motor windings and drive schemes

These current clamps for an oscilloscope will help a clown view the voltage and current phase shift lag or advance, so one can see diagnostically if they are improving the cos Phi relationship incrementally. The LCR meter will help one to determine his Direct and Quadrature inductance. That would allow a competent tuner to tune a capable inverters band width ratio (BWR) for optimal performance in SVC FOC commutation..

● Voltage: 24V –92V (Safe for 6S to 22S LiPo). Optimal performance at 20S LiIon ● Voltage spikes may not exceed 100V ● Current: Continuous 500A, peak 680A. Values depend on the temperature, switching frequency and cooling of the device! ● 1x 5V 0,5A output for external electronics ● 1x switchable 5V 3A output for external electronics ● 5x switchable and variable 6-24V (15A combined) ● 1x static output, variable 6-24V ● 3.3V 0,5A output for external electronics ● 9 axis IMU ● Modes: DC, BLDC, FOC (sinusoidal) ● Supported sensors: ABI, HALL, AS5047, SIN/COS and other encoders

The current ramp setting is used in all control modes. It limits the slew rate of the idq setpoint, produced by the torque & flux controller, to avoid destabilizing the drive by rapid transients (esp. in sensorless mode). If the torque setpoint is driven by a higher-level controller (e.g., velocity controller), then the current limit should be set to a high value (typ. at least 5 kA/s) to avoid interference with the outer control loop. In the voltage control mode, the iq limit is ignored because the uq voltage setpoint is supplied directly, bypassing the Q-axis current controller.

The voltage ramp setting is used only in the direct uq voltage control mode and ignored in all other modes. In the voltage control mode, the id current regulator is still active as usual. The direct voltage control mode is not recommended for use in any application except in propulsion drives of multirotor UAVs, although even then it is recommended to use the velocity control mode instead.

The current controller bandwidth ratio (BWR) is the ratio of the idq controller bandwidth to its update frequency (which is determined by the control system). Higher BWR values increase the responsiveness of the drive to load and speed variation but also increase the phase current noise level and the risk of self-induced oscillation. Lower values produce smoother phase voltage and reduced noise but increase the risk of stalling the motor in the face of rapid transients. For most practical applications, the BWR value is typically between 0.01 and 0.2.

Underdamped phase current control loop causes the motor to produce audible high-pitched noise even at standstill and/or zero load. The under-dampening may be caused by the BWR settings being too high or, commonly, the inductance and/or resistance parameters being set incorrectly.

Motor control fundamentals - Telega v1.0 Reference Manual

If you don't understand something in the contents of the reading it is truly ok . I am aware It isn't for everybody. Some do not care and others it may be over the head. That's not a problem nor does it make those individuals wrong or stupid, but you may have an EV perhaps or for those who are generally interested in the tech this may help your understanding of how the sinus drives work. This is very informative in that respect.

This is the same control software architecture in the Logic side IC with on board fet drivers that can agnostically set the drive for optimal performance with the propeller load. To me it is exceptionally state of the art for UAV's or I would not waste your time with it.

The parameters found by this procedure can be used with model-based controllers, such as the incremental nonlinear dynamics inversion velocity controller.

"The parameters can also be used for sizing the drivetrain for a given application. As the propeller/fan torque is a function of its torque coefficient and its angular velocity, one can predict the torque at the shaft and the angular velocity for the given lift; next, knowing the motor parameters, the motor controller, DC link, and battery requirements can be deduced. For more information on this, refer to the Drive power transfer equation.

The torque and thrust coefficients are strongly dependent on the airspeed. For the dynamics identification to be valid for forward flight, the test should be performed in a wind tunnel."

Er ist willkommen.
Wenn Sie glauben, dass Okon aufgrund der Informationen, die ich Ihnen gebe, nicht jeden Tag hier eingesperrt wird, sind Sie ernsthaft verrückt. Normalerweise braucht der Speed-Clan etwa zwei Tage, um sich zu beruhigen, bevor er wieder anfängt, falsche Träume für seine Freunde zu posten. Er schreibt hier alle Formellinks und relevanten Informationen auf. Er wird sie mit seinen Freunden teilen, die Schlauer sind als er, um sie zu bestätigen, und dann dumm da sitzen und darauf warten, dass ich seinem begrenzten Selbst noch mehr Wissen zuschicke. Er wird alles im Dunkeln ausprobieren. Er weiß, dass die Handgranate, die er windet, viel Hilfe braucht Helfen Er ist hier eingesperrt und ein Vollidiot, der in den deutschen sozialen Medien für seine Freunde sein Maul aufreißt, während er jeden Tag RUHIG in meiner Schule sitzt. Und mittlerweile sollten sie es wissen, sonst sind sie auch verdammt langsam. Er ist eher eine Schlange als ein Krokodil.

Dang! Borat has already got his seat for class today. Its 5:13 am EST! Hi Ralph I see you are ready. But you are a bit early for class today.😀

I reposted the photo of the scope clamp amp that is needed to look at the phase shift advance or lag.

Viele neue Mitgliedschaften, also haben wir jetzt eine ganze Reihe von Charakteren im Raum. Du glaubst, ich wüsste das nicht? Ich dachte, ihr Rounder seid mit 79,4 % zufrieden? Ich werde euch nichts zeigen. Ihr könnt lesen, also führt die 79 aus oder fliegt. Es liegt an euch, denn ihr wisst, dass 79,4 % nicht gut genug sind, oder?

Viel Spaß beim Campen mit dem Mini-Ich.

Excellent post Christian. They can't ban that and it is not off topic because Powercroco says there has been nothing better. If you look at e the generated BEMF of the two machines comparatively anyone would be able to quickly see it is significantly cleaner with a higher winding factor as well.

There is hardly more practical evidence than an oscilloscope or power analyzers waveform capture of the cleaner machine in FFT! The machine with the lower total harmonic distortion is going to have a better p.f.. The 3040 at the same Kv should generate 5% more torque if not more based off the difference in winding factor alone. The physics that govern the 78% are the same ones that would abide here.

I would tell the doubtful hobbyist he may contact Andreas Lehner at Lehner Motoren who has a dyne meter if he has any further questions and move on. Don't allow yourself to be drawn into the fallacy that is sure to follow.


Thank you for the post🖤

Thank you,

I guess I don't really understand why any hobbyist would think a 5050 outrunner in direct drive would develop more torque per amp than an in runner this size connected to a planetary gearbox! In direct drive already the inrunners at Lehner engines have proven efficiency well over 90% in 100s of world record breaking demonstrations at the row pool in Munich.

Again another wonderful post. This is how you deal correctly with fallacy across the forum. This is all that ever has to be posted. The actual slot fill not the increase of copper over a purposely simple factory wind.

He does excellent work but, It does not grant him the ABB Hubertus post Doc $300,000 scholarship he thinks he deserves for re winding a wild wound factory drone motor with his hand. Hopefully they can calm down now.

But they may act out because they probably are not enjoying class today. It's the final exams b4 Christmas break which are no joke.

Thank you

Wats up cap? Hard to survive in a Rogerian world huh? You prolly didn't realize a Lehner 3040 was 60mm in diameter. It's a large class inrunner. It just a little shorter thanwhat is normally run in the 2.4 metter cats I showed you. Alot of clean big power. The 5050 won't competes especially when you consider the inner can turn to 60000 rpm and need no special inverter to handle it.

Hi Hubert,

this post i have done because of your exelent schooling of Borat and Schmidie . Spezial as Schmiedie vote for the Nazi Party in Germany the AFD with the knowen Nazi lover B. Höcke. We do not need such politics.
I will,also,show Thomas that he has do learn the basics of motors , best with slotcar tuning like this paper. It has so much know how the speedflyer never learned.
https://www.sac-stolberg.de/wp-conte...Car_Motors.pdf .
This is they way to learn know how and you are doing the same at an higher level of new brushless motors.

Happy Amps and Happy X-Mas to you and your familie

Hi Christian,
At this point the Americans know what they all about. Ralph calls US Anglophiles. That means we kiss the queens ass .😘 He is disrespectful and doesn't feed "black trolls" 🖤 but that's okay. Please remember not to be drawn into bad behavior that was predicted. I wont because all you need to do is post the facts about electric motors. The Eta is truly 79.4 without and rounding. 5040 is 78% the 5050 is 80%. Its all very poor efficiency for a BLDC so it does not matter about the eulogy he has posted there. No insults just the facts and mathematical data. Stay in that groove. Do not engage in fallacy and the truth is easily exposed. BTW I care less about politics my favorite president is Benjamin Franklin. As far as I know fascist only make up a small part of the worlds population and are a dying breed on the way to extinction . I enjoy much more the technical discussion about engines and tuning motors more efficient than 79.4%. Benjammin Franklin is the one president that makes real changes no matter what side anyone is on....ALWAYS! Get you a couple million of him and you no longer have everyday problems people cry about both ways all over the world. You can use ONE to buy a motor with efficiency higher than a 79%.

Keep making nice post.
Hubert

[Clugh]

Better yet forget the lil squirt.

Christian will you do me a favor?

Could you please post your slot car magnet zapper and a explanation. I may want to play with post assembly magnetization so I can look at axial pole pair and segmentation of the magnets. The Drs still recommend it when possible so id like to look at it despite the hybrid windings I plan to use.

ThankYou
Hubert

[Clugh]

250 people viewed on it so if you could show your version it would be nice for the hobbyist here. Since I stated at the beginning that the thread would bounce around a bit I don't think the forum minds if you post the slot car motor information here in my thread. I certainly do not care and am fine with it.

Chris you may be able to boil the magnets into demag then glue the segments in the let them cool and or possibly zap them. I need to learn this Christian. you are one of the only hobbyist left to teach us this please.



Thank you
Hubert

[Clugh]

Tell Kai he knows how to purchase a Lehner. You tell him Ralph has not given you an engine for free either. Dont give him a damn thing!! You tell him fly the 78% @ 1000 euro as he is happy with it

If he wants your motor you show him Andreas Price list simple as that. You dont owe them Scheiße!

I mean it Chris you tell him BUY iT LIKE HE DOES THOSE 79% 5050s!!!!!! at 8 to 900 euro maybe more!!! Kai can know I also wind several brands of motors more efficient than that.

He is the one stuck on stupid.

[Clugh]

Es macht Ihnen nichts aus, diese Bastarde zu verschonen. Sie veröffentlichen weiterhin die tatsächlichen Zahlen zu diesen Engines. Die Maus kann am Ende des Tages bei 78 % Ralphs Dreck fressen. Das ist sein Vorrecht, aber Sie müssen nicht aufhören zu posten, nur weil Ralphs Handlanger das sagen. Die Person, die den Mund halten sollte, ist die, die immer herbeieilt, um zu helfen, aber nichts über Engines weiß. Ralph bringt ihm das bei und Ralph ist hier an meiner Schule. Was weiß Kai also? Nicht mehr als Ralph. Sehr wenig. Deshalb ist er mit 79 % der Engine-Führer.

Machen Sie sich bereit für eine weitere Runde von Berechnungen für die Truppe. Denken Sie an die Erfolgsformel für das Posten.
