Listen to the scorpion . It sounds much better. you hear the triple stack at 60hz 3660 RPM isolate it on purpose so you can hear it. If anyone is laughing they can look at themselves as the joke and ask for the 41's FFT capture with a castle inverter in hall sense mode as soon as it actually mounts some. You see I have provided you all that versus the video of slow boats running an inverter not at all in this discussion if you have been reading here.
The whistle is approximately 1.7khz according to the RTA!
You see the optical trigger I built and I sent you the code in BASIC for the on screen requisition years ago.
No analysis is really needed though I can provide that but just a good ear is all you need. I can assume they need my analysis of their noise from me because they don't have that or the diagnostic tools to do so themselves?
The little silly scope doesn't have FFT capture apparently.Comment

Maybe you didn't see this original on topic post? Clearly fallacy wont win any "contest" here competitor. I know you think you are smater than them but to think an intelligent hobbyist doesnt know any better is a real delusion. They can trust at least their ears .

The sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform. It is so named based on its resemblance to the teeth of a plain-toothed saw with a zero rake angle. A single sawtooth, or an intermittently triggered sawtooth, is called a ramp waveform.
The convention is that a sawtooth wave ramps upward and then sharply drops. In a reverse (or inverse) sawtooth wave, the wave ramps downward and then sharply rises. It can also be considered the extreme case of an asymmetric triangle wave.
While a square wave is constructed from only odd harmonics, a sawtooth wave's sound is harsh and clear and its spectrum contains both even and odd harmonics of the fundamental frequency. Because it contains all the integer harmonics, it is one of the best waveforms to use for subtractive synthesis of musical sounds, particularly bowed string instruments like violins and cellos, since the slip-stick behavior of the bow drives the strings with a sawtooth-like motion.
Subtractive synthesis is a method of sound synthesis in which partials of an audio signal (often one rich in harmonics) are attenuated by a filter to alter the timbre of the sound. While subtractive synthesis can be applied to any source audio signal, the sound most commonly associated with the technique is that of analog synthesizers of the 1960s and 1970s, in which the harmonics of simple waveforms such as sawtooth, pulse or square waves are attenuated with a voltage-controlled resonant low-pass filter. Many digital, virtual analog and software synthesizers use subtractive synthesis, sometimes in conjunction with other methods of sound synthesis.

Low pass filtering again but I know the leaders know already from their gloves what is happening here with the generated wave forms....
Apparently they don't understand what a DSP capable MCU can provide. Unfortunately for some people their epithet and fallacy wont provide any answers in electrical engineering.Comment

It is common sense for a real electrical engineer to grasp. If a square wave drive is made up of only odd harmonics and a 10 pole motor woks at the 5th and 7th you wouldn't want the sub working 2 pole sinus signature present if you want to boost the 10 or 14 pole. Sinus operation truly has no place with a 10 pole BLDC machine. The entire preface of making it a 2nd harmonic sinus is backward as hell in the first place because the 5th harmonic is the one that generates the torque. The 2 pole harmonic is what destroys the magnets in the first place.
I hope the speeders are paying close attention to reality.Comment

Ihr habt alle Hände voll zu tun mit den Unruhestiftern in den deutschen sozialen Medien. Macht aus dem nächsten Bann für ähnliches Verhalten einen Dauerbann! Er hat nicht die Macht, einfach Unrecht zu haben. Ihr wisst alle, wie sie sich verhalten. Es gibt keine Reaktion auf den Support. Warum musste ich erklären, wie die Support-Diagramme eigentlich auf der Grundlage der BELASTET-Drehzahl funktionieren? Warum musste ich die richtige Übersetzung dafür zeigen oder wie und warum man den richtigen Motor mit dem richtigen Wechselrichter wählen sollte? Trolling ist umgekehrte Psychologie, denn bitte helft mir und zeigt mir die Informationen, die ihr habt. Ich muss keinen Motor zur Untersuchung an eine Universität schicken, weil ich das selbst machen kann.

Hi Clown,
Now you have to see that you can get over your inferiority complex again, isn't it? That's difficult. Your pages copied from others and fake photos. What are you trying to fool the readers here? Prove it at competitions, but nobody wants you at a competition. Your rewound motor won't even accelerate a 2.40 meter boat to 40 mph, the motor will burn up before that. Your fake pictures are useless, the motor doesn't have the physical requirements to be able to deliver higher performance. You have to live with that. With the big Lehner innrunners we can accelerate these boats to over 140 mph and that over long periods of time. Your little motor only survives such performance for a few seconds.

Who is a clown your moma?Originally posted by Chxpress View Post
The fact are as follows....
The boats are slow an underpowerd as they barge along and 2 of the aligns can move the boat just like it as its more efficient and more power dense so how do you figure???
Id never do it because thats a slow ass boat! Its about 20 mph slower than the 1/8th scale boat my custom wind was designed for.
See there's the intelligence into a forum. No answer about all the commutation noise they plainly here or the engineering fundamentals of a wave form. You suggested to Ralph who runs a BLDC motor to impliment a FOC drive. And he get nothing out of that but more loss a less high speed capability. Now you will feed to the people that somehow the picture from the scopes are fake. But have not a ''real: on so id rather be a clown than a total dumb ass that doen't have and electrical engineering degree. And too dumb to realize they fly planes not boats.
No hobbyist in America is inferior to an electronically ignorant sauerkraut that doesn't understand how an esc he purchased works and cannot accept the data that he's been shown about it.
we fake audio in video too... everyone can here it commutates much more cleanlyComment
-
They can take its constants and put it in Holles calculator and then determine how do you figure it cant push the boat if you did. Ralphs engine can to and that's already proven at the air prop. it isnt anything special to more 2.40 meter boat around at less than 60 mphComment

Put your 41 in it and then Ralphs motor. finally put in mine and then ask him how he figures no one can touch his Frankenberry But its well behind both motors based on its measure results running it with an inverter.
The scorpion certainly sounds better in real life! and the Align is more quiet than it all you hear is the fan. It funny how I have to keep showing proof to someone that has none.Comment

I guess the show is for Americans since the Germans already know the truth and time you out for your rediculous conduct that does not change the data or the facts. HE CAN TURN MORE PROP THAN YOU FOR THE SAME AMPERAGE SO HE WILL HAVE NO ISSUE MOVING THE BOAT IF YOU DID.
I am more power dense with higher efficiency than either of these posted motors all anyone has to do is feed the data into their favorite calculators and compare them.

This also has nothing to do with the poor advice to them about hall sense with a castle that is not going to work that way or prevent any damage to their rotor due to slotting effect. It is incorrect no matter how much fallacy you pass. I'll always have a defeating answer because its fact based. It is not a sinus inverter so there is absolutely no reason to run it with a sinus motor. As everyone can see the scorpion runs much better with the castle BLDC drive.
Nonsense wont change this. Clowns are disruptive and unable to have Rogerian debate on the subject matter because I won the technical argument 20 post ago. Now you are just acting like a real idiot.
Have fun because the hobbyist are not stupid. they can see clearly what's going on.
It is simply called jealousy and the reaon they ignore you one the German social media. Go back there and post your hall sense theory with a casttle and they will laugh you out of the room.
go try it and see. They've read all of this and they know who knows what. You told them they needed to come here for the RIGHT information and so they have. My credentials are not the ones they question.
All the data and academic works support my position. You do not have any so you are left with name calling as your only reprise

Put the numbers in YOUR calculators and have him tell you why My engine or Ralphs wont push the boat if his did. he's a bit off I am afraid. My eta is 96% by his same calculations and more power dense .His breath and sharp tongue smells like ass but my motor can push my boat 90 mph at 148 amperes and those cats are not doing even 60 mph. He actually thinks those video are impressive while most experience boaters would find them a rather embarrassing as some metric of FE boating performance . Ralph ask JAGS what they think about the two catamaran videos. they will laugh. That's nothing but a hobbyist and his average running boat that cost him close to 10 grand for no god reason because it is middle of the pack in performance.
The record holding catamarans do not have a 41 series outrunner in them and that is fact
This is the truth no matter how much epithet is thrown my way.
All this occurs because you don't know a sinus from a BLDC signal and cannot accept the facts and fundamentals of electronics even though you claim to have a deep understanding on the open forum. They have seen you own email where you admit you are not an electronics expert . its embarrassing because they already know the truth from your own words and personal email.
The more you act out the less credible you are but you say in your mind they are laughing at me. Ok i'll just keep collecting the money they pay me while you struggle to sell that thingComment

An HK scorpion has held a 2 lap record in our books your 41 series Lehner does not and probably never will. No one buys it. This is also fact that I have nothing to do with. You need to be mad at yourself. You designed it!!!!
But you have definitely given me the direction id go in If I was considering the two. Id buy the scorpion and run it as it should be in BLDC mode. No way id buy that noisy thing to run with a castle that you can not explain apparently. The on topic academic question are always left open.and in its place real ignorance is injected. no one will purchase your insults...
No one that's in the field professionally will respect it. It is true ignorance personified. the only place you can conduct yourself this way and still be part of the discussion is on a forum where anyone can say anything. that's why certain people stay clear of bodies like the IEEE then come to the forums and try to play god with a room full of people with limited understanding> when a real engineer comes around with real questions the epithet comes out which is an awful quality within itself. There no way I can let my self be associated with a douche bag like that.
The speeders are right to act the way they do towards you and I will never defend you with real data again. We will see how you get along there with them. As soon as you jump into one of their threads with your motor and drive advice they are going to give you the business kick you out and ban you because you cannot have Rogerian debate.
WATCH!
This awfully ignorant thing you do is why you do not have and can not retain any friends. i cant and will not dignify any more of you pathetic epithetic nonsense. if you cannot have a discussion and defend you position with real data there is nothing left for us to talk about. U can do the name calling alone. I'm fine with whatever you convince a forum of. They all know from the data freely shown that honestly my motor is performing better than yours and they have the accounts of the pilots I serve.+
Good luck with the name calling and whatever you say you can apply the same to your moma in return .I don't need to say it every time its my auto response about non motor topics. I might respond if you come up with something that actually has to do with the subject matter you are wrong about. and have already admitted you were wrong.. I cannot blame Ralph and his friends because you really are not a likable person. For some reason you Truly think you are better than other people. That's why the entire German forum is against you on every topic you create. Every reply they make fun of you. Is this where you learned to be so disruptive? No one and I mean no one is fond of you there. usually people can make and keep at least one friend. Even Sebastian doubts your motor now because you dont know how to defend a position academically. That's a real social problem that needs to be professionally addressed. The dentist should have a reference to a mental health provider so you should seek her leads and get some help.
I'm sorry but something is seriously wrong with a person that doesn't remember their own words and emails. i think their are underlying issue like dementia possibly because there seems to be slippage. When you argue back with your own words. Or maybe people truly lie that much to serve the narcissistic componentry in their make up.
obviously hes going to say anything. none of it explains a sinus wave form but somehow this is what he has to offer the forum in defense of his technical argument. Draw from it what you may. if its intelligent book it into your folders and forget what I've shown you here...
I'm fine with that. If you say donkey slowly 5 times you might fly faster. The hobbyist can test it out! This vendor is mad I am telling you the truth. The engine is not selling well. It simply did not make the wow moment in the hobby market he expected . Everyone is a donkey now....
if its a sinus machine which really make zero sense if its 10 poles castle certainly isn't the ideal inverter for it and that's that. If he thinks it is my advice to any hobbyist here or aboard is you let him hook up the halls TO HIS FIRST and show you the extended load handling it brings since he has never done it himself. Thats fairly relevant to the understanding of how things work. What you been offered is very generalized understanding of the electronics but nothing as discrete or as proving as accepted waveform theory. According to this poster not even castle know how their inverter works. This is the same nonsense Ralph tried with YGE engineers! No you its YOU guys that do not understand how the inverters work.
Stop kidding yourselves. You cannot explain all the commutation noise you are hearing when it runs.
WHY????

Hi Hubert,
As everyone can read in the forums listed below what a Judas Hubert Haregtt is.
If you are well disposed towards him and parrot what he says and don't criticize him, he will praise you to the highest degree. But if you contradict him and don't write what he likes, you are only insulted and called incompetent. He has acted like this since I've known him. I promised a friend before he died that I would take care of Hubert. It doesn't work, I've tried several times. It always ends the same. He claims to be a Christian, but he doesn't act like a Christian at all. Anyone can read about this behavior in the forums. He is banned from all the big model building forums in the world and there are reasons for that.
All usless bei Hubert Hargett, 1BOHO and many other names. Nothing real to hold in hand and competive in competition. Nothing
Incidentally, Lehner sells at least min. 5000 engines to the USA every month. Hubert 1 or 2 in 20 years.
