Alternative motor windings and drive schemes

[Clugh]

Für 1000 Euro wird mein Speedmotor mit Thermoschutzleitungen und vielleicht einem Hallsensor geliefert, sodass man zwischen offenem und geschlossenem Regelkreis wählen kann und nicht in der Luft explodiert. Ich weiß besser als er, wie ich seine eigenen Daten zum Vorteil seiner Piloten nutzen kann.

Man kann den Thermistor direkt auf das Y-Bündel kleben oder einfach die gewickelte Spule auf Eisen aufkleben.

Das ist für niemanden außer Okon eine Raketenwissenschaft.

[Clugh]

In the video you can hear the damage is already done at take off! See the arc flash? The fets were sheared completely off by this motor in non protect mode. It destroys YGE's

They have their hand and eyes unprotected in there with a flash hotter than the sun. Thats what Christian is talking about in his letter with safety concerns with 72 to 100 volts three phase AC.

Look at the sheared fets. they are totally absent!

A 20 cent thermistor can prevent this Look at the fuselage now.... 20 cent pilots is what a thermistor cost. Ralphs way cost you about 10000 dollars USD

[Clugh]

HE IS VERY LIMITED IN WHAT HE EMPLOYS!!

Ihm beim Lügen zuzuhören wird tragisch für Ihre Investition sein. Kai hat ihm die Daten gegeben, wie er überlebt. Du glaubst, Ralph gibt sie dir weiter, indem er seinen Motor mit integrierten Thermoschutzkabeln ausstattet.

Absolut nicht. Er lässt dich verbrennen und zahlt ihm dann mehr für die Reparatur. Du bist echt ein Trottel. Denn du lässt dir von ihm erklären, wie der YGE funktioniert, und er hat keine Erfahrung mit dem Bau von Wechselrichtern.

der Thermistor kostet 0,17 Euro

[Clugh]

Most competition pilots use thermal protection or at least monitor it in real time through telemetry . See it here on the TP can?

[Clugh]

I am not hard to convince so Ill start adding thermal protection leads as a normal part of my engine building program. Once again you get more with US than him. Ill invest the 20 cents for each one of you... Id rather you keep your plane in one piece

I'll order thermistors TODAY!!!!

You can also make this small investment into yourselves after the fact.

[Clugh]

With Dr Okons speed motors here are the highlights.


*You cant get thermally conductive security on your wires
*You can only get standard NMB steel bearings
*You can only get a 2 layer delta or wye wound machine
*You cannot get a twisted pair winding
*You cannot get thermal protection leads or hall sense embedded in your machine
*You cannot get slot wedges or flux barriers.


Damn boys what can you get? Anything that improves a motor you cannot get from the man. How is he a "guru" ???

He only winds what most DIYers can now. Even they can produce a beautiful full size wire hybrids PYROS without wires all over the place

Großbritannien ist dazu in der Lage, aber wer in der Krokodilwelt kann endlich ein Modell produzieren, das so aussieht und funktioniert, wie es sollte??? Ich warte jetzt schon seit sechs Jahren. Oder glauben Sie, dass Dr. Gerling sich Ralph Okon beugt? Die gemeldeten Daten zu den Maschinen beweisen auch, dass es funktioniert

[Clugh]

I'm sorry, but I've been modeling over 40 years and for someone to come into a technical forum and tell you to disable the smart capabilities of modern inverter technology today like telemetry and thermal protection to promote their 68% engine is real bull ****.

A custom wound motor is much less important than your model to me and it should be to you.. So id rather you have every single protection you could from it if it were to fail.

Thermal protection, locked rotor protection, secured wires. whatever we can do. If you have an inverter that is agnostic of course I absolutely want you to fully employ it.

The most important thing you can ever do in a high voltage high powered electric model is prevent the smoke. If a winding does nothing but allow a motor to run cooler with less vibration at heavy loads. That's very significant in throughput power delivery. A few percent count as well as a few degrees in operation.

[Clugh]

Just clearing modal vibrations from an operational motor does wonders for the bearings life. You can ignore it but it all has a detrimental price on the overall performance of the machine. Please stop telling the hobbyist it doesn't work because that is not at all true. It is measurable as well as mathematically proven and you have not measured anything. Post the data and stop telling stories ! The winding technology is proven in every aspect of e traction.

Ill tell any hobbyist here like he is my blood brother that these things work. Don't you let someone mislead you for a profit.

What Is A Pt1000 Sensor? [Complete Guide] – Peak Sensors

Hi ,
The next series of pyro 650 "growlers" as he call them are nearly complete for mike Padron. I'm about to run them

Only the winding heads have been encapsulated with boron nitride infused high temperature epoxy. I do the slots after the stator is boded to the carrier with 620 Loctite. I also tap the 2mm keyway and add a long 2mmx.04 cap head screw in place of the steel dowel. The stator is truly locked in place. The dry ceramic ABEC7 bearings have been treated with tungsten disulfide and a proprietary high speed oil. The 2nd bearing may also be secured with the 620. I hadn't decided yet but bearing retention is truly what 620 is for. .


Ill leave the boys recorded constants as usual but I can tell you this so far. It is identical to the last two I did for TDR's. My brothers and the Haters have already read that heli pilots review. He is more than satisfied and they landed perfectly on his desired Kv.


P650 13 Tuns YY in 17 AWG.
780 Kv
15.5 milliohms
.
When i run it ill give you the idle current and have already shown you video that that is what I measure. It isn't made up at all. That's the purpose of video confirmation. I pull the curtains back and let you see a lot more proof than the 2 editors in wunderworld.

To me this e-motor in size a capability is easily on pace with a dynamite Pylon .40 or 500 motor. in weigh power and rpm capability with about two more hp. Of course the e traction also has a much more linear torque line. I think it finishes right around 320 grams. At what it could really peak on 10 cells its more like a .65 cu in nitromethane 2 stroke marine engine.

She can easily peak over 5kW for much longer that 2 seconds...

BTW
Im still looking for the pylon prop that is right in my face somewhere....
The 7x10 is really nothing for testing if you ask me. Kinda weak. I like a little more load when Im breaking in the motor. If you could quantify the small prop to around 1000 watt you have a good place to look at bell temps of a hybrid versus the conventional winding.. The 7x10 on 8 s lipo pulls around 3.4 hp on the 910Kv p600. . a 1000Kv would probably be more impressive. In the 14 pole that is am 4+4 (8 turn yy) for 1017 or the single layer yy around 980 Kv

The German is telling stories that no one replies to there and hadn't tested anything. Trust me.. If he had data that disproved it he would post it! You never need to worry about listening to fake news.

Sorry boys I told you incorrectly about TDRS. These two 13 turn P650 pyro motors are going into two Diablo Mini copters

I'm off to winding and testing more motors.

Later

"Halo" the two motors are complete.
The measured constants on a castle Hydra Ice HV v2 200 @ 10 degrees timing.
Kontronics Pyro P650 6+7 parallel wye in 17 AWG.
Kv 780
Rm. 15.5 milliohms
Io 2.7 amps at 32 volts.

You can play in any calculator with an arbitrary idle current and see how much difference just 7/10 of an amp makes to the Max Eta.. Its significant especially with respect to the efficiencies broadness at different speed. If i could manage even an amp less its a significantly different machine in its efficiency curve. A low idle current tells you quite a bit about a machine and how it smoothly it is commutating. The higher the speed the more the bells balance is critical for the best quiet machine. Any extra noise or vibration that raises the idle currents robs measurable power.


Danke,
Hubert

[Clugh]

On to the Brenner drive 600s..... and a few special winding projects....

Later.....
Hubert

[Clugh]

BTW
A spy is all up in the house. LOOKIN" in depth at a conventionally wound parallel wye machine ....

But no comparative data to a hybrid has been posted on the GSM yet..

6 years.....

[Clugh]

This is a COTS wild bundle in hand wound NEU 24N22P 4638 289 Kv on 10s and an APD 200F3 .turning a GM 12x25 direct drive.. I can have quite a bit of fun around 12000 rpm various GM's this is only around 80 amperes draw. the efficiency is just below 90% here. 68% is a long ways away and this is no where near a big block yet. These motors are battle proven in battle bots.

Be careful what you ask for Bruder.. I'm saving them for prime time....

Thanks for your time and patience,
Hubert
