big electric motor 3000 kW - startup test sound
Вставка
- Опубліковано 28 вер 2024
- We present a typical 3000 kW motor start in our test field. You can see and hear how such a big motor starts. The accelerating takes about 90 seconds from 0 to 993 min-1. This is the maximum speed that a 6-pole slip ring motor of this size can achieve.
Enjoy the big motor starting sound!
The video shows a three-phase asynchronous motor with slip ring rotor with a nominal voltage of 10500 V and a power output of 3000 kW. It features a shaft height of 630 and a total weight of approx. 13.5 tons (including cooling system) - a typical motor size of our day-to-day business.
Electric motors of this type and size are used, for example, as main drives in cement mills or as compressor or fan motors. Slip ring motors are the motors of choice whenever high starting torque or low starting current are required. They are especially suitable for heavy load inertia applications.

Please tell me there are others who searched for Electric Motor Sounds XD
We for example. ;-)
I did for electric motor start
Yeah man what's up, I search this all the time
Yeah dude but come on it.s nice yiu fill the power yo
In his full power he can push the hole africa lol
Oh come on, I'm stuck yet again in the electric motor start-up corner of youtube.
And your videos make it worth it! :) The attention to detail is awesome. Thank you for such content!
Thank you for that kind of comment! We really appreciate it.
Very smooth running, should be available just in time for Christmas.
Shall we wrap it up nicely?
I was looking at the Amps thinking "30 Amps? Not bad for how large that motor is." But then I realized its running with 3,500 Volts
Thank you for your attention. The 3500 Volts is the single line voltage, the main voltage is 6000 Volts. Full load current is 380 Amps, the 30 Amps is the no load current.
@@MenzelMotors that's insane- (as in awesome)
@@MenzelMotors, I find it strange that running it without load would consume that much power. Does it really require nearly 300 kW worth of cooling in that situation? I assume all that power gets turned into heat. I could run that for two and a half minutes to heat my apartment for a day.
@@seriouscat2231 I'd assume that the currents are the apparent currents, not the real currents. Hence, a portion of that current isn't doing actual work but is merely being circulated (= reactive current). en.wikipedia.org/wiki/AC_power#Power_factor may be of help to understand.
Reactive current is wasted somewhere eventually. So you are suggesting that that is not the actual power it draws, but only something that goes back and forth between (capacitors in) the controller and (coils in) the motor?
Shall we upload another video with electric motor sound?
Yeah, many more please
yees
Let's create our own subculture ... "People who love electric motors!"
@@MenzelMotors Diese Subkultur ist schon wohl etabliert, wenn auch sehr versteckt. Persönlich finde ich den hier immer noch am besten: ua-cam.com/video/pdSKT_8OfKg/v-deo.html

This takes me back to my days in the mining industry where we had a 3900kW compressor motor. Started using a Korndoffer starter.
Thank you for your comment. We have been delivering many of our motors to the mining industry, for example in South America.
The sound of electric motors and combustion engine is what terrifies me during my childhood times and now its the opposite
Thanks for your comment. It's nice to hear that you like the motor sound.
So now the sound of non-electric motors and non-combustion engines is what comforts you ? :P
Air blowing out of big dark vents and big fans still is terrifying to me.
Aniruth Dinesh So I’m not the only one
@@i.i.iiii.i.i Stirling engines
You can definitely post more videos of electric motors spinning, the sound is beautiful lol
Glad you like them. Yes, we will produce some more.
That is a LOT of rotational mass! I definitely wouldn't want to be anywhere near that thing if something let go...
Thanks for your nice comment ......and thanks you for your concern.
But you don't have to, because the motors are anchored.
Love that sound. Like a plane engine
Glad you like it. This is what it sounds like almost every day at our test field.
Jet engine literally a kind of motor
This video reminds me my classes of "electric machines" all about electric motors in technical high school
Thank you for uploading this
Greetings from Argentina
lovely greetings back
Loved how this channel keeps on commenting on similar videos.
Thanks.
I had a neat 100 year old Century Repulsion-start AC motor. Friends and family Could never understand why I enjoyed starting so much.
It's a passion ;-)
Working with these must give such a half life vibe 🐸
It is impressive and fulfilling at the same time. It is also always nice to see the purpose of the applications. Hospitals, pumping stations, hydroelectric power plants. This is our infrastructure for life.
If that would not be perfectly balanced that axle would break through the metal casing like nothing and then hit and kill everything in its path! The level of engineering and precision is absolutely staggering! And in this case you really need every component to work perfectly round the clock.
You are right. In this field of engineering, every millimeter must be precisely calculated and produced. Friction and thermal management as well. That is why we test our performance data in our own test field and can proudly claim that our company has been perfecting this know-how for decades. Such medium voltage motors and high voltage motors perform their work mostly under severe conditions. We thank you for your comment and are pleased that you like the work of our employees in the planning and factory floor.
Can I know how much it cost loaded test for 11 kv 750 kw and 850 kw motor??
Variable frequency controller seems popular with big motors since it allows the magnetic field to rotate in the stator slowly at first and the rotor can catch up. Then as the rotor picks up speed, increase the frequency on the stator coils.
Thank you for your comment. Yes, a frequency converter not only allows to regulate the speed of a motors, but also saves energy.
Große Elektromotore sind schon toll anzuhören.
das stimmt
This makes me think of them massive hard drives from the 80s I took apart and would watch and listen to them spoil up back in the early 90s when they were outdated... Your motor is a tad bit bigger though. Great video.
Thank you very much. We are happy that you are enjoy watching them!
Interviewer: How does an electric motor start?
Me: 0:30

@@MenzelMotors VFD or just a voltage ramp?
Thats music in my Ear, i love mechanic sounds.....so beautyfull😂
We're glad we made someone happy again.
Super Teil, mit Gleitlagern und Kurzschluss Schleifkohle👍
Sie kennen sich also aus?
Allerdings kenne ich diese Schleifkohlen eher von Gleichstromaschinen oder Drehstrommotoren mit FU zum Schutz der Lager.
I wish the motors in Tesla’s sounded this dramatic. Love the sounds of these big motors spooling up.
Yes, there is nothing like a decent motor noise.
Control panel looks awesome too
Thank you for your comment.
I wonder if this would start up at 400V as well :)
Was this running in star or delta?
No, it would not start up at 400 Volt, as this would be only 7 % of rated voltage, that is not enough.
One day I am addicted to civil warning sirens, another I am searching for big electrical motors startup.
Glad you found us ;-) We are addicted to big size electric motor sounds
worked in a GE repair shop for 42yrs, torn down, rebuilt, and tested hundreds of different motor, dynos too!
Good craftsmanship and many years of experience are worth their weight in gold!

Sounds Like a Turbine But Better.
Thank you for your comment. Our motor test field crew can enjoy this sound almost every day ;-)
I would love to see photonicinduction have a few days with one of these. Assuming he has enough power to make one of these pop. Would be quite a task though.
I miss him uploading
Thanks for your comment. This is a no-load motor test.
Wird mal Zeit beim Menzel durchzuklingeln, ich brauch so ein Ding in meinem Elektro-Kangoo.
Sollen wir ihn hübsch einpacken?
@@MenzelMotors Das ist mir nicht so wichtig, ich hoffe nur ihr haltet euer Versprechen, welches ihr bei 1:34 rechts oben indirekt gegeben habt, dass der Kleine wirklich mit 1,5V und 10mA Stromaufnahme zu betreiben ist. Habe nämlich extra 0.33mm² Kabel verlegt. Ihr wisst ja wie das ist, Leistungsgewicht und so.
after 0:29 seconds I keep turning on the big boxes ... crazy
sounds good ;-)
We have a 1000 hp GE motor running our I.d fan at work. Thing sounds crazy starting up
Yes, we love motor sounds!
Great video! Greetings from Venezuela.

What is the load of the motor ?
Everytime i hear those big beasts start i think of Half Life's Test Chamber x)
we don't, but hope that's okay anyway
@@MenzelMotors it's okay, that's why we have spare scientists ;D
у меня отец тоже в советское врем в НИИ гидроугля испытывал сверхмощные моторы
285 A an Strom ist schon nicht wenig und 10500 V alles andere als eine geringe Spannung ich frage mich wo liegen die Grenzen des machbaren bei Elektromotoren ab wann wird es mit der spannung kritisch bzw ist noch machbar und wie hoch darf der maximale Strom sein der dann noch beherschbar ist , das würde mich brennend interresieren ob es so einen Motor gibt ist zweitrangig da es mir um die Technische machbare Grenze geht , seit ich meine RC Boote von verbrenner auf Elektro umgebaut habe bin ich nur noch begeistert was mit Strom machbar ist die performanc ist einfach Wahnsinnig gesteigert worden und ich kann mich jederzeit um entscheiden ob ich mehr geschwindigkeit haben möchte ode einfach längeren Fahrspaß haben möchte und muss dafür nur den Propeller wechsen bzw den akku wechseln bzw umstöpseln von 3 Zellig zwei Akkus Paralel oder die beiden in reihe schalten und so mit doppelter Spannung zu fahren was dann zu aberwitzigen Geschwindigkeiten führt mit eben über 100Km/h oder um 40 Km/h mit sehr langen fahrzeiten von über 30 min bis zu 2 stunden je nach Gasstellung und auf maximale Geschwindigkeit getrimmt um 5 min fahrzeiten wobei Top speed nur wenige Sekunden anliegen

Happy to hear that you like it.
loved seeing how this worked
so do we, thank you
Нормальный движок в кофемолку :)
идет хорошо ;-)
Is this running off an inverter? Is it on AC power? Brush or brushless? Sounds fucking INSANE.
Why do small motors use grease instead of oil ?
Grease causes a lot of bearing problems
Dear Sir, grease lubricated bearings are a much lower in cost and standard articles, which do not require big lubrication systems - but if the design is suitable and grease quality good there should be no issues from our experience.
Mmmmmm what happens when you mix a curious/bored opperator, a softstart bypass and and a celling. My best guess? A fun friday afternoon!
maybe ;-)
So what is the red disk inside the housing? Cooling fan? Can't believe it had that much run out. Had to be 1/4". Just looks like a catastrophic failure in the making.
Thank you for your comment. Yes, this is the cooling fan. It has nearly no run out at all - just appears optical on video like that.
Voltage? Starting system? Motor type? Looks like a wound rotor of some type?
Thank you for your question regarding motor prformance data. These are as follows:
Motor type: Slip-ring motor

ah oui la c'est du moteur voila l'engin, quel type d'industrie utilise se modèle la????
Les moteurs électriques de cette taille sont utilisés, par exemple, comme l'actionnement principaux dans les usines de ciment ou comme moteurs de compresseur ou de ventilateur.
@@MenzelMotors ok Merci pour l'info.
Par contre j'imagine que côté électricité ça doit demander un abonnement spécifique comme une arrivée direct via haute tensions avec son poste de transformation.
Ça doit être sympa à visiter des installations comme ça.
Merci en tout cas...👍👍👍
I used to work for a company that serviced electric motors like that, only when they test ran them they would have to use the crane to get them started spinning and it took much longer for them to reach full speed.
Yes, the older generation of our employees can remember that. In the past, we also had to make use of various aids.
What would happen if I touch the terminals with my bare hands?
I can well understand that you want to touch it. Unfortunately, it is not recommended :-)
Is that motor used to rotate the Earth?
Yes, fasten your seat belt and hold on to the handles!
Gosh that sounds cool!
We are happy to read that you like the sound of our big electric motors!
This would come in handy for the zombie apocalypse.
Suspend the motor vertically with a hefty piece of flat steel mounted to the shaft below about 3 feet off the ground. Like a giant lawn mower.
The souls of the dammed rush mindlessly towards the sound of this beautiful machine to get eviscerated by the blade.
To keep the area clear a hopper below the blade can funnel "their remains" into a conveyor belt to be stored elsewhere.
tell me you guys also sell hoppers and conveyor belts :)
Halloween is getting closer and closer :)
You people have a very nice test field. do you also test loaded or only unloaded? We do the same in the Netherlands. Nice profession
Thank you very much. It's a full-load testfiled also for manufacturer-independent motor tests up to 13.8 kV. If you would like to know more about it, please check our website: www.menzel-motors.com/motor-test-field/

Felicitari pentru descriere.
Vă mulțumesc pentru comentariul frumos. Încercăm să le prezentăm cât mai multe detalii fanilor noștri.
sounds like a normal electric train to me
... next stop Berlin main station ;-)
So this motor is over 4000hp?
Thanks for your questions. 3000 kW = 4023 hp
I am guessing that the shaft on this motor is a belt drive?
Thank you very much for your question.
No, it is coupled directly.
How is this motor started? You can't just switch it on like a 4 kW AC induction motor, is it started by a inverter, or something else?
This is a slip ring motor, so the stator is just switched direct on-line and the rotor is started up by a resistor starter. But you can also start this and larger motor sizes direct on line - you just need the proper grid! These grid calculations and voltage drop calculations we offer for our customers to ensure the best suitable solution.
This thing is a JET!!
Thank you very much! Yes, the sound is quite something ;-)
Welcome on board.
Can this motor put in a ship?
Thank you very much for your question. This type of electric motor is not used for ship application. We produce very similar powers for ships, but usually with squirrel cage rotor and anti-friction bearings.
What does this motor run?
Electric motors of this type and size are used, for example, to run the main drives in cement mills or as compressor or fan motors.
what are these motors used for?
This type of motors are used for mills, compressors and similar heavy duty applications
Sir motor maintenance you have vedio
Thanks for your question. Our main business is electric motor manufacturing and supply. Our motor manuals include advices for maintenance, but not in video format.
I'm interested motor maintenance jobs you have any maintenance team?

Это запуск на пониженном напряжении. В эксплуатации - звук вполне реактивный, пуск быстрее секунды, даже у синхронного. Просто на заводе нет ввода достаточной мощности...
Запускаем мотор стартовым приводом по медленной рампе. Запуск DOL с полным напряжением и частотой 4 секунды является реалистичным. В тестовом поле мы начинаем гораздо медленнее, чтобы определить любую потенциальную проблему и возможность выключить.

At 1.35 you can see 6069 Volts and 30 Amps
I laughed when I saw those buttons on the control panel, Eaton I think? Yeah I even see some other Eaton products there. I wonder if it's all Eaton including the panel meters.
The test panel was manufactured by our automation division www.elektro-pawils.de , using various suppliers. Also Eaton buttons are incorporated, yes.
@@MenzelMotors Thanks for the reply and link. I think it would be really cool to explain a little bit about the panel, what the multitude of panel meters are reading and what motor characteristics you're doing quality assurance on because it looks a lot more in-depth than just rpm, amperage, and voltage. It also lets you brag about the quality of your QA.
I'm wondering if they read things like stator resistance, slip frequency, no load voltage, rotor resistance, induction leakage, etc. Sorry I double checked one of my VFD manuals to see what motor characteristics auto-tuning looks at. In the case just a Teco-F510 manual.
It almost sounds like a jet starting up..I'm used to hearing the loud humming sound as it starts up....
Are you a pilot?

background too noisy, since this is a "test sound" video so it will be better if the video captures motor sound only with clean background (I know it is very difficult).
Thank you for your comment. We give our best, but actually this is a motor manufacturing plant, so lots of action and noise around.
E,soprattutto a che tensione di alimentazione?
Grazie per la tua domanda.
Questo motore ad anello rotante ha una tensione nominale di 10500 V.
La tensione di fermo del rotore è di 1680 V.
Trattandosi di un motore ad anelli la corrente di avviamento è molto bassa e influenzata dall'avviatore. Tipicamente questi motori ad anello rotante possono avviarsi con una corrente nominale doppia.
@@MenzelMotors la faccio questa domanda anch io sono uno di voi

how many hp? would it work in a high speed train?
It comes up to around 4000 HP. Typical applications for this size of slip ring motors are sag mill and cement mill applications.
I need one...- for my blender
All right, we hope you live on the first floor because our boys won't carry it up.
Wow, 3 million watts? Is that running or starting watts? And what on earth needs that kind of power to run!?!?
High pressure industrial compressors. I worked on and around 3 that had 11,500 Hp General Electric Synchronus motors running at 4160V/3 phase and drawing 1100 amps while running loaded.
@@CannonFodder873 yikes. Thats crazy. Do they have to have their own power generating station?
@@torque395 Sort of. Our generator is capable of 11 Megawatts and runs around 7 to 9 MW usually, to offset the running load of the plant site as we use MORE than that. It lowers the electricity costs for a 24/7 high utility use site.
@@torque395 Just an FYI...our site was 27,600V/3 phase drawing ~ 225Amps/phase. I'll let YOU do the Math....I just retired after 32 years.

thanks for your comment, there might be a few more videos that you will like
Ein altes Video.
Heutzutage undenkbar, daß solche Motoren noch irgendwo verbaut werden.
Wir haben doch alle von den Grün_Innen gelernt, daß, um Sonne, Mond und Sterne zu retten, nur noch der riehzeikelbare Gummizug-Motor zum Einsatz kommen darf.
Das Video ist erst 3 Jahre alt und wir haben in dieser Zeit schon noch ein paar davon gebaut, gefilmt, ausgeliefert und in Betrieb genommen. Manche Produktionsanlagen würden ohne diese Dinger still stehen. Wir können sie aber grün anmalen, falls das in Zukunft gewünscht ist.
@@MenzelMotors Erstaunlich, daß es tatsächlich noch produzierende Unternehmen in der BRD gibt.
Das dürfte ein Stirnrunzeln bei den Grün_Innen hervorrufen, die sich zum Ziel gesetzt haben, das deutsche Volk zurück in die Steinzeit zu bomben.
This would be ideal motor for nice meat grinder.
That would be a shame for the entrecôtes. This motor is rather made for grinding rocks.
@@MenzelMotors yep right, it was just joke ( failed i guess ). The motor is a beast.
Krass, wofür werden 3000 kw Motoren benötigt? Das Ding muss ja sicher einen netten Anlaufstrom haben. Also wenn ich denke, dass wir früher mal Heugebläse mit 20 - 30 KW Motoren hatten - und das war ja von der Zuleitung schon immer recht lustig - aber da hängen ja noch 2 Nullen hinten dran
Herzlichen Dank für die Frage: Elektromotoren dieser Art und Größe werden beispielsweise als Hauptantriebe in Zementmühlen oder als Kompressor- oder Lüftermotor eingesetzt. Schleifringläufermotoren sind immer dort gefragt, wo hohe Anlauf- und Losbrechmomente realisiert werden müssen, extreme Laststöße auftreten oder im Verhältnis zur Leistung kleine Anlaufströme erforderlich sind.

Das hat ein russischer UA-camr gemacht. Ein Brushless Motor, der für große Quadrokopter verwendet wird, hat er am Rahmen befestigt mit ner Kette als Übersetzung. Dazu ein passenden Motorregler, weil brushless Motoren drehen sich nicht, wenn man direkt Gleichspannung auf die Motorklemmen gibt. Brushless Motoren brauchen elektronisch erzeugte dreiphasige Wechselspannung, damit sie sich drehen. Und das macht eben ein Brushless Motor Regler. Wäre auch zu umständlich, mit dem Akku mehrere hundert mal in der Sekunde die Polarität an den Anschlüssen zu wechseln. Im Regler geschieht das über MOSFET, die sich gegenseitig abwechselnd ein- und ausschalten.
Zum Geschwindigkeit regeln nimmt er ein Servotester aus dem Modellbau und als Stromversorgung Lipo Akkus.
Kein Witz, der hat das Fahrrad bei ebener und gerader Strecke auf 100kmh gebracht.
Das war allerdings nicht das einzige Projekt, was er gemacht hat, in sein BMW hat er mal ein Motor aus einem Hubschrauber eingebaut und den Wagen tatsächlich fahren lassen, das Fahrrad hat als Antrieb schon mal den Elektromotor mit nem 40 Zoll Carbon Propeller oder ein Miniatur Triebwerk aus dem Modellbau gehabt. Hier in Deutschland ist sowas wohl keineswegs erlaubt. Aber das ist Russland, da schert sich keiner rum, wenn man an sein Fahrrad ein Flugzeugtriebwerk hat und in seiner Tasche ein Kanister mit Kerosin.
