Congratulations
You left out alot of specifics, but either way...its not a point higher in efficiency than the normal 5050 you've been winding in Holles calculator.
Enjoy your motor. its still suitable for your pilots....

I can raise the torque output and efficiency a point without spending money on a prototype stator just by changing the winding, so Is it a win?

And then they try to catch me up in it read this bs
The 'Ami:" for Americans hasn't used any tricks wtf is he talking about. THEY are the ones that run at zero degrees timing to take values when they actually run greater than 18 degrees timing which would report a lower ETA. They fudge daily. I don't lie to people to sell them trash that's their game.
I invite anyone to contact Brenner contra drives and ask him has Hubert ever made him a false promise about power delivery or efficiency. Ask Brenner what I told him when he asked what would his efficiency be after the wind
ANYONE MAY CONTACT HIM HE IS RIGHT HERE
.Is there Anyone Who Can Rewind my Motor - HeliFreak
Mike Padron's number is listed you may call him and ask him what promises or false claims has Hugh made. Youve lost your minds and make up things because were doing much better here in "AMI" There is a good reason Holle's ignoring you.
I have zero to do with the many failures in Germany and their desynchronization which is a result of the magnets in a lousy noisy machine wind topology from 20 plus years ago. You can not tell amateur fools anything.

Hallo Dr. Okon...(Borat/powercroco/boho1)
Ich hab's euch doch gesagt, ihr seid Unruhestifter. Seht euch nur an, euer Gastgeber hat euch gerade abserviert. Haha! Ihr, Thomas und Christian, steckt in letzter Zeit ständig in Schwierigkeiten. Keiner von euch sagt jemals die ganze Wahrheit. Und ihr Idioten kennt nur solche Trugschlüsse wie die, die ihr gerade demonstriert habt, die euch Idioten von normalen Diskussionen abhalten. IHR SEID INKOMPETENZ. Hab' ich's euch nicht gesagt?
Ich lache laut über euch komische Deutsche... Ihr könnt untereinander klarkommen, weil ihr alle Arschlöcher

Thats incorrect Dr Okon there are papers on motor desynchronization . Youve been told BY ME umpteen times your pm loses adequate field at high load and the motors are noisy and cannot time correctly at the zero crossings. But you do not listen and the three stooges often act ignorant when you all cannot figure something out.
The phenomena is certainly known in hobby. So no matter what you say it exist and occurs on your motors in Germany often because it seems to be a resounding theme there..
Lets look at a drone article about the subject matter.
What’s an ESC Desync?
In simple terms, a desync occurs when the ESC loses synchronization with the motor. When the ESC and motor go out of sync, the ESC’s commutation timing—essentially, the precise timing it uses to keep the motor spinning—gets disrupted. As a result, the motor stalls and causing your drone to crash. The drone experiencing ESC desync also makes stuttering noise or a specific motor acting erratically before the fall.
However, not every instance of a “drone falling out of the sky” is due to ESC desync. For instance, if your quad drops to the ground without any spinning (all motors stop spinning), it could simply be a failsafe or loss of power. Typically, during an ESC desync, the drone will spin or roll rapidly out of control because all the motors are still spinning except one.
The best way to identify an ESC desync is by examining Blackbox logs. An ESC desync occurs when one of the motors stalls (stops spinning and thus stops producing thrust), prompting the drone to command that motor to spin harder, causing the motor signal to reach its maximum of 100%.
Causes of ESC Desync
Desync occurs when the ESC’s timing of the commutation sequence fails to keep up with the motor’s movement. This misalignment results in a loss of synchronization, and the motor essentially stops. Here are some common causes: Excessively High RPM
Motors with ultra-high KV ratings or those spinning at RPM that is too high for the ESC to handle, are more prone to desync issues. As the motor spins faster, the ESC has to process the commutation timing more rapidly to keep up. In extreme cases, the ESC can struggle to maintain synchronization, resulting in desync.
When the motor is spinning too fast, the ESC can miss the motor’s “zero crossing” (commutation), while electrical noise can exacerbate the situation. If the ESC cannot accurately detect the “zero crossing,” it will not know when to fire the next pulse (to create the necessary magnetic field to push the motor), leading to the motor eventually stalling.
Sudden Speed Changes
If the motor changes speed too quickly, the ESC may not be able to adjust its commutation timing fast enough, causing it to lose sync with the motor. This is especially common in situations requiring rapid throttle changes, like aggressive maneuvers or hard braking during freestyle flying. Damaged ESC or Motor
Physical damage to either the ESC or motor can lead to desync. For example, damaged motor windings or a faulty ESC can disrupt the precise control required for commutation, leading to synchronization issues. In my experience, older motors or ESCs that have sustained wear and tear are more prone to desyncs. Electrical Noise
Excessive electrical noise can interfere with the signals between the ESC and the motor, leading to desync. This can be caused by wiring issues, poor connections, or other components creating electrical interference.
Not Everything Is Desync
One of the most common misconceptions is that any incident causing the quad to drop is a desync. However, not all issues that look like desyncs are actual desyncs. Here are some examples of issues that can mimic desyncs:- Burned Motors: If a motor draws too much current and burns out, the quad might spin out of control and crash. While it might look exactly like a ESC desync in video, it’s not caused by ESC desync.
- Overheating or Faulty ESCs: If an ESC malfunctions or overheats (e.g. temperature protection), it may cut out, causing the motor to stop. Again, this isn’t a classic desync but rather an ESC issue.
- Battery Voltage Drops: A sharp drop in battery voltage can cause the ESC to lose power momentarily, leading to motor cutoff. This can look like a desync but is actually a power issue.
Select the Right ESC and Motor Combo
To prevent ESC desync in the first place, choose an ESC and motor combination that works well together. Motors with very high KV values should be paired with modern ESCs capable of handling fast commutation speeds. Use Additional Filtering Capacitor
It’s crucial to have a low ESR capacitor soldered to your ESC’s power input if you haven’t already done so; it can help reduce some of the electrical noise – often times it’s the root of the problem. I have a guide on the type of capacitor you should choose, and where to solder it to
BLHeli and Betaflight Settings
To fix ESC Desync, or reduce the likelihood of its occurrence, you can try different settings in BLHeli and Betaflight. Not all the suggestions may be necessary, but one or some of them could be the answer to your problem.
BLHeli Settings:- Rampup Power (or Startup Power): Use a lower value, such as 0.125 in BLHeli_S or 12% in BLHeli_32. If the props hesitate to spin when you arm the quad, you might need to slightly increase the rampup power until you find the sweet spot where the motors start spinning smoothly upon arming the quad without causing ESC desync.
- Demag Compensation: Set to high, as it aids the quad in recovering from desyncs instead of merely dropping to the ground, albeit at the cost of some performance.

So when you see demag compensation maybe a dumb ass will figure it out.Comment

How are you not ignorant? How many times have a told you about the capacitors? You are idiots coz I work with this bs in real life everyday and you are just self aggrandizing hobbyist that need to sit your ignorant asses down some where and be quiet.

And when you put constants in a calculator it is a simulation which is adequate and acceptable fine for most motorist to compare things. I hate when ignorant people do not know how to use a calculation tool correctly and complain about it but they cannot write and accurate program themselves.. There's absolutely nothing wrong with Holle's calculations Its the same as the Maxon groups.
I agree that the empirical charts of one little munch in Germany means zero to the field of engineering or the next mans plane or setup.
THOMAS....esp You examine electronics without a lick of diagnostic measure.
Nothing but forum clowns.

This is why I think its funny the LEADERS think that just going to an FOC inverter will thwart desync. Where Lucas gets that idea I have no idea but it is actually the opposite. The FOC runs out of computing speed well before a six step drive will. He is not a drive designer. Trust me that is not his forte no matter what he's told you.
Deshalb finde ich es komisch, dass die FÜHRENDEN glauben, allein durch den Einsatz eines FOC-Wechselrichters ließe sich die Desynchronisierung verhindern. Woher Lucas diese Idee hat, weiß ich nicht, aber es ist genau das Gegenteil. Dem FOC geht die Rechenleistung deutlich früher aus als einem Sechsstufenantrieb. Er ist kein Antriebsentwickler. Glauben Sie mir, das ist nicht seine Stärke, egal, was er Ihnen erzählt hat.
Danke,
