Alternative motor windings and drive schemes

[Clugh]

Efficiency as a function of slot wedge permeability The 30 mu looks promising because its so broad right? But don't be fooled itz good for the rotor and pm but it turns all the noise back on the core and you have elevated core loss. About 2 mu is sweet. Where you don't actually lose torque. 30 Mu may not fit a speed plane application if you want the most torque dense machine. A 30 mu wedge will block some of your torque producing harmonics to give you that level of attenuation of slot harmonics into the rotor and PM and you will lose some static torque output because the core loses some of its power.. just like the low pass filter you have to let the right harmonics through the slot to make good torque.

30 mu wedge is still worth looking at if you are going to actively cool the core with liquid or cryogenics.

The Magnovol, an industrial grade semi magnetic slot wedge material, pictured is 2 mu. I have the material here at camp America.

Es ist wirklich schade, dass Christian Lucas, jamaicaman, pierre_mousel und Rds Ihnen für diesen lächerlichen Beitrag nur mit einem Daumen hoch weiterhelfen können.

Bleib ruhig, sonst gibt es hier nichts zu sehen. Ihr habt beide nichts Sinnvolles zu dem Thema beizutragen. Und natürlich hat er dir erst im Dezember 2019 erzählt, wie effektiv der Wind ist. Du solltest wissen, dass der bayerische Designer seine Worte damals hier veröffentlicht hat. Er wirkt auch nicht so bipolar … auf uns.

Das erklärt auch, warum er auf Powerditto war und die Sicherheitsmaßnahmen der Website umgangen hat, um sich die Hybriddaten anzusehen. Und natürlich hat er mir unzählige persönliche E-Mails geschickt, in denen er dich als dumm bezeichnet hat. Jetzt ist er wieder dein Freund und weiß nicht, wohin er sich wenden soll. U2 sind wirklich eine Minstrel-Show.

Dein Wickelforum ist langweilig. Es ist dort nicht einmal mehr interessant genug, um es zur Kenntnis zu nehmen. Was ist denn los? Bilder von christlichen Spulen von vor 30 Jahren kursieren noch sechs Jahre lang?

Ich bin damit mehr als zufrieden und muss weder davon noch von einem konventionell gewickelten Skorpion 5050 mehr sehen. Ist es nicht ironisch, dass die Motorleiter hier versuchen, ihre Interessen vor ihren Kollegen zu verbergen, mich oder etwas, das ich tue, aber fast täglich in den Foren ihrer Kollegen erwähnen?

Das Wichtigste, wenn Sie trollen möchten, ist dieses Foto für Ihre Kollegen und eine Scope-Aufnahme, die zeigt, dass Sie und LRK oder Single Layer Scorpion BEEF keine Sinuswelle erzeugen.

Das ist für dich und Ralph Lucas. Ihr seid offiziell Teil der Crocoworld der Anhalter.

Glückwunsch.

Genießen Sie Jurassic Park

I guess he will tell you that this also will not suit a pilot that wants to fly faster even though its 12slot 10 pole configuration just like the pilots run.. It is another way to kill all that noise. Semi distributed 4 layer winding. It would allow you to run fat noodle wiring with less proximity and skin loss. Again itz not about the lowest DCR is more about the AC because those losses come at a frequency not at stall.

A 1/4 of a percent less in copper losses is not anything to get excited about in his conventional wye machine. If he saw a percent more in his hybrid then his routing was very poor. To bad he tried to manipulate your understanding to the prototype winding I showed him in 2019 and not the refined version in 2025. he always lies and manipulated your understanding this way. He truly truly lies all the time to you boys.

While he is typing gibberish I'm constantly improving my craft. The P800 6 delta coils are already secured and neat with boron nitride infused epoxy waiting for the open ended wye coils to be added.. Ill also run a HK hybrid for them.

And report those constants so they can know the truth and find a new winder in 2026 if you cant keep up with todays winding tech.

Hi Ralph,

You here like usual.....

I can get the silver wire 250 feet at about 12.60 cent a foot. I can very well order just enough and build them the precious metal machine for about 1500.00 dollars and it would have a much lower resistance and higher thermal capacity than what you wind there and Anakin's aluminum coils that are the worst conductors in that noisy open slot contraption of his. It would be very eazy to get around your thoughts and ignorance about the DCR and if the motor last forever versus what they get with your knockers .Its is well worth it. Until you make a change the motors wont run any better. The only time its hit 603km/h is with the APD HV PRO controlling it.

An eta of 93% is pretty standard so I don't know why you two think youare it. All the high end brands can do at least that. Armageddon hasn't done it YET!

He couldn't buy the speeding ticket if he wanted to but he sure spends alot on your scorpion motors to never get there. But at least he knows how to protect his YGE 320 from it.

u2 could not be more brilliant than to enter into technical debates without an iota of data or video to support it.

where is their data Americans? from which he determined it doesn't suit the application of speed flight especially if he never loaded it into a plane. or recorded any constants?

You need to question him every opportunity you get because you all know that is not a legitimate assessment . Youd trust a person that spent half a day on the subject matter?

You should ask yourself what he thinks of your intelligence if you are supposed to believe it with nothing to support it. He truly thinks the average American hobbyist is a fool. All you have to do is look at their post and threads about our election.

They think you are stupid right along with 47th

because some of us have done things like deny global warming exist! and pulling out of green energy they think were all idiots in agreement. They havem't a clugh how divided Americans are on policy. They are full of these assumptive stereotype about Americans so He thinks he can tell you anything and you'll buy it and in some cases like helifreak and crocoworld. That worked for awhile but as u can see when his pilots that read here started inquiring about things like different ball bearings they get pushed off his mailing list! And locked his thread.

He is really upset people like Mike Padron and Brenner Sharp chose me. People highly respected in their branches of RC. I don't just supply a limited group with a singular goal.

Boats , Planes, and Helis. It doesn't even matter to me but he is not for you or he wouldnt call you all Anglophiles.

For those that do not know that means we kiss the queens az..

Hier versucht dein neuer Freund, mich dazu zu bringen, segmentierte Magnete zu kaufen, um dich, wie er sagt, zu „schockieren“. Aber ich bin schlau genug, um zu wissen, was der Typ dann tun würde: Er würde behaupten, er hätte Hugh erfunden. Ich kenne den Mann so gut.
Er ist begeistert von meinen Spulen und findet sie wieder aktuell. Jetzt stimmt er deinem Beitrag zu dem Thema zu. Siehst du, wie lustig das ist? Er ist ein verrückter Bruder..

Da Sie die Effizienz verbessern möchten, ist die beste Methode, den Crocoman zu schocken, die Anschaffung segmentierter Magnete. Vielleicht hilft ein sehr dünnes Diamanttrennrad oder der Kauf kleiner Magnete, die in die Rotorglocke eingeklebt werden. Das reduziert Wirbelströme deutlich. Hans Lehner und ich haben unsere Bootsmotoren auf diese Weise optimiert und erfolgreich gemacht. Denken Sie darüber nach. Ihre Wicklung ist auf dem neuesten Stand der Technik, und der wärmeleitende Kleber ist der beste Weg, die thermische Optimierung des Motors zu verbessern. Die Reduzierung der Magnetwärme ist der nächste Schritt zur Verbesserung Ihrer Motoren.

As you are on the way to improve efficancy , the best way to shock the crocoman, is it possible for you to get segmented magnets ? Maybe a very thin diamond cutting wheel will help, or to buy small magnets and glue the in the rotorbell. This will reduce eddy current realy much . Hans Lehner and i we have tuned our boat motors this way and win . Think about it. Your winding is state of art and the thermal conductiv glue is the way to improve the motor thermal optimisation. Less magnet heat will be the next step you can improve your motors.

Now he's on the German forum agreeing with the "Croco man" that a hybrid wound motor is useless for a speed pilot.

"Shocking" isnt it.?

.

Yet the hybrid wind on any motor I wind will remove the heat from the magnets without making it his Lehner 41. So I do not need segmentation and neither does any one else that adopts the most current winding technology.....

The Aluminum Oxide and Boron Nitride infused epoxies I already use take care of the rest. So please enjoy your new discoveries in these materials and winding practices that will eliminate the need for magnet segmentation which when done right uses post assembly magnetization not a damn diamond Dremel wheel anyway. That's not how Hanz does it. .... with a Dremel wheel and polarized magnets already glued iinto the ball. That is nutz from the get go, and would waste alot magnet volume and available space at the width of the wheel. That is also additive for all the radial slices.

He wont be setting me up to make a fool out of myself coz that bs he suggested with the Dremel wheel wont work out well anyway. YOU go ahead and try it but you did already Ralph and it DID NOT WORK DID IT?

You're smoking if you think that's how this 41 LMT rotors segmented pm's were manufactured.... its post assembly magnetization all day and with the Lehner 2 pole inrunner its really easy. Just like his slot cars in fact. Do you see how tigghtly the segments sit to one another/ This is not done with a freaking Dremel diamond cutoff wheel and it ensure you regain the magnet volume to have very thin insulation between the close segments. An insulative thermally conductive epoxy that doesn't brittle and can take mechanical shock would be ideal

With the 10 pole motor you need an elaborate fixture with a degree wheel and an exaggerated core. it also will be zapped in two shots at different locations to be fully magnetized and you can go too far with the juice so you really need to know the amperage require for the PM you use to do it correctly.. The Bavarian knows full well all these things have to occur for it to be done correctly and the voltages and capacitors needed can knock you down. Go ahead and listen to him . the only other way is to insert the magnet pieces heated to curie. If you go too far with the heat you'll still have to zap it

I laugh at the emails and save them for times just like these when Mr. is in manic mode Ralph!....as a physician you can diagnose Mania much better than me and you're licensed to hand out a prescription for some relief.. you need to work out a weekly regimen for him.

You can get whole pre segmented pm from places like Arnold Magnetics but these companies are not set up to accommodate privateers. You could get a free working sample well before you could get a small production run. They want volume to do it and that cost major coin.

How do you on the GSM talk about motor improvement with purely a winding then suggest any of these other methods anyway? They are not windings and have nothing to do with winding. This is rotor and pm manufacture. A pressed pre fabricated litz coils is also not hand wound.

you want motor improvement with purely a wind but dont want to change what you currently wind.

Make that make sense...

Show me some data and they will acknowledge you again.

A deeper idea of what is involved with post assembly magnetization if you want to magnetize the non polarized segments. So you have unpolarized pm material that you can easily glue into place then magnetize them after the rotor is assembled.. Note the voltages and amperages involved in a two shot method out of their magnetizer. The last time I've seen that much juice is servicing huge industrial spot welders at Daimler that welded the Body ribbing on the school busses. The huge cables to the spot welders were water cooled.. This huge thing probably is water or oil cooled in the caps and high voltage transformers.

This is truly how you pull motor magnet segmentation off if you do not buy pre segmented pm

You can certainly find high voltage electrolytic caps that can deliver that type of instantaneous amperage but you still have to find the high voltage source to charge them.

BUT have you ever seen or heard the arch flash at just a 480 V 600 ampere fuse tripped from a dead short?. You can mess this one up not knowing what you are doing if you want to.



You gone have one time to "f" it up an you will not have to worry about it ever again cap because you are done if you get hit !!!

Ya exit is gone be like my boy in Bayern without the chute !!!





But seriously if you find some transformers that can push it you can build something. if you take the right precaution you can do it safely. I've seen lower voltage magnet zappers systems around 600 volts with 600 volt caps so you might get away using transformers out of a commercial microwave oven to charge them.

Hi Dr Okon.

[Clugh]

So don't be too confident about his thumbs up in agreement to your statement about the hybrid.. He only put that thumb up ya booty because he is still here and tries to remotely to annoy me.

He knows the winding works and works very well ,so please be careful with the company you keep Dr Okon....

You see he said no one on the forum knows anything about electric motors especially the crocoman, so I wrapped it all up for you in a 4 post package so the.modus operandi in Bayern is understood by all the thumbs

He can offer you a thumb to tickle your fancy but not any empirical data on the star - delta hybrid winding on 12 slot 10 and 14 pole external rotor BLDC machines like you inquire about.



Take care....
Hubert

[Clugh]

Das Komische, Dr. Okon, ist, dass ich auf Ihrem Bild sehen kann, dass Sie den Hybrid mit einfacher Stern-Dreieck-Schaltung gewickelt haben. Es handelt sich nicht um eine Parallelschaltung wie bei mir, daher sind Ihre Kabel lang, genau wie bei einem Motor mit einfacher Stern- oder Dreieckschaltung. Die Verwicklungen durch Ihre Verlegung sind Ihr eigenes Problem. Schlagen Sie es nicht als Problem für andere vor, denn die gleiche Version wurde mit dicken Drähten auf einem 700er in Cambridge, Großbritannien, gewickelt.

KONTRONICS PYRO P700
4 turn wye + 7 turn delta Hybrid

Have a close look at number 3

Americans motor heads can determine from the Kv and no-load currents and turns counts compared to the conventional windings if there is an improvement in efficiency. Its enough here to make that obvious determination if the Dr and his friend in Bayern know anything about electric motors and physics which they do, so they are a sad couple when they play laurel and hardy and concurrently falsify information about electric motors on the GSM.

They both are already aware of this data.

This crazy alter ego powercroco doesn't need any data from his German forum colleagues to compare when he knows full well they do not have any

This was the first attempt by a hobbyist, so the doctor has to work on his skills, because as you can see, it fit, the engine was running and the data came along..

What's the doctor's problem, guys?

Pure nonsense!....

Wenn er die Kabel nicht richtig verlegen kann, ist das sein Problem, nicht Ihres!!! Der Grund, warum er diesen dummen Thread überhaupt gestartet hat, ist, dass er seinen eigenen Thread wegen der Schuld des Witzbolds nicht wieder eröffnen kann.



He tells you his application has no use for it which is VERY false but still what about all your own individual applications readers.... Do not listen to it. It's nonsense!

A serial wound 5 turn wye + 9 turn delta hybrid on the Pyro p650 is going to bring a Kv of approximately 536.@ 1o degrees timing on the castle Hydra Ice HV 200 v2 there would be numerous ways to route it and still end up with the equivalent circuit just like the conventional windings. You can also wind hybrids with only 6 wires and no solder points if you know how.. but a proper silver solder join creates a cooling sink right at the connection nodes of the delta and wye machine.



perfect attendance....

You know you need a weekly regimen of medication too because you could just talk to me and make these ridiculous proclamations you are in Germany right here direct Ralph... You plum crazy just like Luke cap.


Tell me is this deep GER-mania u2 suffer from?
