Alternative motor windings and drive schemes

[Clugh]

Its old news that if the ratio of radial component to the main poles isn't correct in the Halbach the torque ripple increases versus being minimized a 12N10P/14P hybrid wind is so much simpler...

[Clugh]

Adam has a direct drive contra Halbach with PARALLEL slots for F3A but it didn't win the worlds. A single pyro 600 with a traditional wind with a contra planetary gearbox did so already you'd be going backwards. The Halbach is PM heavy machine. Very few in the EV world are currently looking at a Halbach for ma$$ production. It's quite the opposite; they are looking for pm-less solutions. Like synchronous SRM's. Considering that the better solution for the average hobbyist that actually winds his own motor is to wind an adequate wye to delta serially connected machine for tangible improvement over the 12N10P wye windings that have already won many championships in various E flight classes.

Hi ,
This is something you and your friends at motors by Gotha should keep in mind as it pertains to forums technical discussions and false narratives about proven winding technologies, machine failures, and solutions as well.

Honesty is absolutely critical in any technical debate for several reasons:
1. Accuracy of Information

Technical discussions rely on facts, data, and logical reasoning. If participants are dishonest—by misrepresenting data, exaggerating claims, or hiding limitations—the entire debate becomes flawed. Decisions based on false information can lead to system failures, wasted resources, or safety hazards.
2. Trust and Collaboration

Engineering and technical work often involve teams. Honesty builds trust among team members, enabling open communication and constructive problem-solving. Without trust, collaboration breaks down, and people may withhold ideas or feedback.
3. Problem-Solving Integrity

Technical debates aim to find the best solution, not to “win” an argument. If someone is dishonest to protect their ego or push an agenda, the focus shifts from solving the problem to defending positions—leading to poor outcomes.
4. Ethical and Professional Standards

Most technical fields have codes of ethics (e.g., IEEE, ASME) that emphasize honesty because technical decisions can impact public safety, financial stability, and environmental health. Dishonesty can cause catastrophic consequences.
5. Long-Term Reputation

In technical environments, credibility is everything. If someone is caught being dishonest, it damages their reputation and can affect career growth. Conversely, honesty—even when admitting mistakes—builds respect.

Remember this......

The IEEE and other such entities strive to maintain that code of ethics. The data driven information provided from such groups is not motivated by a sale or maintaining someone's ego. Intelligent individuals can clearly understand this reasoning.

Happy Hybrids....

Facts about some inverters discussed over the last few years


APD 120 F3 Rm .0011
APD 200 F3 Rm .00055
APD HV pro 300 20S Rm. .00033
APD HV pro 300 24S Rm .00091

Here are some internal resistances for YGE in comparison They can be found in the German ecalc databases hiding from the Americans.

YGE 120 Rm .0018
YGE160 HV Rm .0013


Castle's
Pheonix edge HV lite 160 Rm .0011
Castle edge lite 200 Rm .0008
Castle edge lite 130 Rm .0010

Don't care what brands people like this is reality. At WOT the YGE runs hotter with more resistance than everything else....

[Clugh]

Gotha is in the house...

So look at this reality....👀

A yge 320 Rm is .0007 a scorpion Tribunis 14-300 is .00065 block commutation and so itz no doubt stronger and faster than the old antique YGE 320.
Do you all see a castle lite 200 is almost as strong as the 320 and much lighter. It is more power dense than the 320...

I know it can log 380 amperes empirically because I did it driving a Phil Thomas SS45 fully underwater like a submarine. But if you compare the YGE to even the 20S version APD it isn't even close. It literally has half the internal resistance than a 320. Twice as powerful.

Honesty will set the 8 pilots free. And the 16S version of the APD really kills a YGE 320.

This makes me seriously wonder do hobbyist just listen to people online they think knows something or do they know where to look for it and actually spec the devices for themselves .

The castle's still runs today . It has never been in for a repair almost 10 years now its run without a flaw in models and on the test bench. No matter who gets mad about it the YGE's are nearly at the bottom of the pile for power density. Part load operation is also inferior to the APD which has synchronous rectification.

So a much better active freewheel operation and brake with much more PWM capability on top of double the power density.

If you have a problem with this you can work it out with a fellow German, George Ohm.

Please enjoy the relevant and real specifications of your chosen device.

Hope you are "Sequre" and that no one else falls for it

Talk to you later.
