Huh, that was a really smooth and quiet start given the size and power rating of the motor. Definitely sounds well balanced, and given the industry those go into, the finest long life bearings available. You must also have a very fancy VFD hooked up to handle the huge amount of power and soft start. As I see mentioned in a few other comments, it has a regenerative breaking ability of sorts, and that's quite interesting. Definitely doesn't hurt to have that when you're running something at that level of power input.

Zeer mooie video's !! Heerlijk om te zien en te kunnen laten zien. Dit is mijn job, maar ik mag dit niet filmen. Dus zeker blijven doen! Top! Klein puntje van kritiek: Het doet pijn aan men ogen (als tester van elektromotoren) om te zien hoe de kabel aan de bornen wordt vast gemaakt. Daar nemen jullie een groot risico. De regel van de kunst is met een momentsleutel. Toch niet met een elektrische slagboormachine. Koperen of messingen bornen zijn zacht, het zijn geen 8.8 draadstangen. Ik heb al heel vaak dergelijke bornen moeten vervangen vanwege het te zwaar aanzetten van de moeren.
Heel erg bedankt voor de leuke reactie. We zijn erg blij dat je onze video's en wat we doen leuk vindt. Ja, u heeft volkomen gelijk, de verbindingen moeten tijdens de installatie beslist worden vastgedraaid met een momentsleutel.

Bedankt dat je hierop hebt gewezen. We wilden geen verwarring zaaien.
Great video! I bet the motor was happy to be revved up with a VFD instead of just slamming it with 6Kv mains! LOL. I like the humor these guys have when answering nutty questions, like: Will if fit my Honda? LOL. Good job! No need to answer my silly question. I did the maths and came to the conclusion that most of the energy from the motor would be used in dragging around a power generating station in the trailer behind the car anyway! Won't work.
Use low voltage AC, and an ammeter. Look for differences in current at a given voltage, testing one phase at a time. It's very hard to detect inter coil shorts using DC, due to the low resistance, and, the normal tolerances of the windings. Short circuits really reduce the AC inductance of the windings, and makes it much easier to detect, by noting differences in current. (Note: there will normally be slight differences in inductance between phases in a good motor) You will actually see slight fluctuations in inductance, (current) by slowly hand-turning the rotor of the motor.
It is a very precise measurement required to properly measure, due to very low resistance values. Most important is a proper connection between measurement device and coil / phase.
This is a good procedure. The coils are all measured during production - and compared. if there is a difference between single coils they should not be used. Connections between coils is done by brazing - there a proper connection needs to be ensured.
This 1,7 Megawatt motor features a IC511 cooling - a rather old-fashioned cooling type. It has gradually been replaced by more modern cooling types such as IC 411 and IC 611. But we still build these motors as these are still the first choice for some industrial applications, due to their various advantages. The tube cooling principle ensures particularly efficient, uniform cooling, because the cooling pipes are wound symmetrically around the laminated core. The primary and secondary coolants are moved by fans on the motor shaft. Read more: www.menzel-motors.com/squirrel-cage-motor/ic511/
We used to run an electric motor at 3.6megawatts, was used in an MDF process, scary shit when the power shutoff under full load it was driving a defibrator
Thanks for your questions. The motor has a total weight of 7300 kg. The final price depends on the configuration, just like when you buy a new car or a house. We are specilized in the manufacturing of customized industrial motors. So there are no standard price lists.
Thank you very much for your comment! I am afraid thought that my engineering colleagues don't share their special design-criteria with me. But that does not wary much between small and large motors.

Вы правы, но, к сожалению, большинство клиентов не разрешают нам снимать на своих заводах, чтобы показать, как двигатель работает под нагрузкой. На нашем испытательном полигоне двигателей в Берлине, Германия, мы можем проводить испытания мощностью до 1800 кВт под нагрузкой и до 10000 кВт без нагрузки.
I know, I know, water and electricity don't go together....But do water-cooled engines of this size exist? We all know that heat increases the resistance of the windings and therefore decreases efficiency, air cooling is not as effective as liquid cooling, thanks
Thank you for your question. We just recently delivered an IC81W motor to a steel plant in Argentina. This was frame size 900 and the motor weight was 27,500 kg. So, yes, they can be big.
The motor is operated via a generator set. This is controlled by a frequency converter. The frequency and voltage are controlled via this, which enables start-up without high inrush currents. If the motor were switched on directly, the starting current would be 4.5 times higher than the rated current for a short moment. In this case 192 A x 4.5 = 864 A.

Thank you for your comment. Of course, efficiency is not a miracle. You can use Magnetic slot wedges e.g. to increase efficiency - but they tend to get loose and destroy the winding. You can also reduce the air gap, which we would not recommend for a Mill Drive that might be in heavy vibrations working. Regarding percentage of efficiency: please do not forget that the IEC Standard for Efficiency calculation has changed, for a machine of the 70’s (and 80’s and 90’) the stray load losses where assumed 0,5% higher than today. Means the 96.3% from the 70’s is according to actual efficiency calculation only 95.8%.
@@MenzelMotors Thank you for letting me know about these changes in the IEC standard for efficiency calculations, I didn't know that. But what was written on the tables of the machines I've seen was measured, i. e. ratio of measured mechanical power to consumed kW. Furthermore, back then there were no computer simulations and his majesty The Experiment judged almost everything. And I think the way this efficiency was achieved was besides the clever design, quite a big material over redundancy. Yes, these were very heavy machines, with the 250 kW 1500 rpm one weighing about 1050 kg. And also they were using not the best silicone steel available even at the time. With cast iron internal cooling frames and usual aluminium rotors.
@@sasho54 1050 kg for 250 kw induction motor isn't much at all. Depending on type, application, number of poles etc such motor can weight up to 2000 kg. So, 1000 kg for 250 kw, 60 Hz is what I call "lightweight"!

Look at the video description or leave a comment.
The efficiency information is the most important information. Don’t know how it’s been used, but hydraulic motors seems going to take instead of the electronic motors nowadays.
Would it be possible to connect this motor to say a Pelton or Francis turbine to produce electricity? I suppose my question should have been ...Is this the type of motor that is or could be used in a micro hydro setup?
@@MenzelMotors is it a certain number, what voltage and amp is normal for no load start, what voltage and amp can keep some kind of speed like 1krpm, 3krpm.
Menzel is you choice when your motor needs to be reliable and individualy constructed. We offer industrial motors for the most demanding quality requirements.
Sorry for the dumb question but I'm a bit confused right now. Back in school we learned that P = U * I. So 6000V x 192A = 1.152 MW. How come this motor has even 1.7 MW?
While this is an Ex-rated motor running on 6kV, made for running 24/7 and probably much more heavy duty, I still don't understand why these motors are so much heavier and bulkier than the electric motors used in electric cars For example, the Lotus Evija, Pinifarina Battista and Rimac C_Two will have 1.4MW (probably peak power though), new Tesla Roadster is expected to have 1MW (also peak), the Porsche Taycan can do 0.44MW continously... but these motors probably weigh around 100kg, not 7300kg. The difference won't be just active cooling, right?
Thanks for the interesting questions. Actually, there are many huge differences. For example: Industry electric motors have a calucalted life time of approx. 40 years continous duty, means roughly 320.000 duty hours. How many hours a car is designed for? If you calculate 40 km/h as average speed with 5000 hours you are at 200.000 km This motor has the 1.7 MW at 1500 rpm, the electric car motors at much higher speed. If they have their power at 6000rpm it is only 1/4th of the torque, at higher speeds even less. We have to compare torque, not power. Our industial motors MUST have extreme overload requirements (by IEC Standard 160% torque for 2 minutes, 190% current for 2 minutes). The given data of the electric cars are just very short peak data, which they can supply for a few seconds. These are just some of the most obvious differences. Apart from the name "electric motor" and physical principle, electric motors in cars do not share anything with electric motors for industrial applications.
Electric motors in cars are not made for continuous, non-stop use at the full-rated torque and speed. You can also say the same about vacuum cleaner motors, that are much smaller and lighter than their industrial counterparts that have the same power.
@@fir3zzz580 Too expensive. Fuel costs ~$70.00 US per gallon, $18.47 US per liter. The engine, running at a reduced speed, (it will indeed produce the torque) will consume approximately 1/2 liter per second, that's $9.12 US per second. Another problem, is that the engine can only sustain that power for 30 seconds at that reduced RPM, then, it will need to be rebuilt. Keep in mind, these engines typically don't have any cooling system. They rely on thermal mass, to allow for a ~5 second run down the track. They use the "burn out" as a means of warming the engine up to a minimum operating temperature, the thermal mass helps keep it from over-heating in the 5-second race. it is then disassembled, gets new rings and bearings, and it's allowed to cool, reassembled in less than an hour, and is ready for the next race. At $.12 per kWh, the electric motor can run for 22-1/2 hours on the same money, that it takes to fuel the dragster engine for one second. While the engine would need a rebuild every 30 seconds, the motor can run continuous for >3,000 Hours at full rated power, without any maintenance! The only advantage the top fuel engine has, is horsepower to weight ratio. The electric motor weighs as much as the dragster, and the truck to haul the dragster in combined! Not a problem, in a stationary application. These large electric motors don't have to accelerate themselves.
How can these irresponsible and Germans just build these massive, productive electric motors without any regard to carbon emissions or water usage? I'm glad to hear that their industrial capacity has been severely reduced.
Relax. We build very sustainably and responsibly. Our motors have a very high level of efficiency. We deliver worldwide. Our engines are located in almost every country in the world. Maybe in hers too. Sometimes they are so irreplaceable that hospitals, water supplies and important areas of life use them.

домашнее точило, могло бы получиться
Что вы имеете в виду под домашней точилкой?

Tightening electrical connections with a rotary tool like that! not in my day.
Thank you for sharing your experience. What type of electric motors did you build or test?
Welcome to the 21st century.
@@Phantomthecat Still on those contact, I would definitly still grab the torque wrench. They damage really fast.
What is the output coefficient of that synchronous motor??
American made for the dodge ghoul srt 426 hybrid gas and electric 😮
Thanks to our community. Leave a comment what you would like to see next!
I would be interested to see a video on measuring torque vs slip characteristic in the test field facility of some large squirrel cage motor
capacitor connections and purposes
Would it be possible to connect this motor to say a Pelton or Francis turbine to produce electricity? I suppose my question should have been ...Is this the type of motor that is or could be used in a micro hydro setup?
*_Всех, с наступающим Новым Годом!!! Привет из Донецка!!!_* 😊😊😊😊😊😊😊😊
Замечательный. Большое спасибо. Привет в ответ.
Привет
Just out of curiosity: How much power does the motor draw at no load? Thank you for that interesting insight!
The active power is very low, only for friction of bearings and losses of the fan, the rest is reactive power for magnetization, which we compensate.
@@MenzelMotors is it a certain number, what voltage and amp is normal for no load start, what voltage and amp can keep some kind of speed like 1krpm, 3krpm.
WHEN YOUR MOTOR NEEDS TO BE JEWISH: MENZEL
Menzel is you choice when your motor needs to be reliable and individualy constructed. We offer industrial motors for the most demanding quality requirements.
Sorry for the dumb question but I'm a bit confused right now. Back in school we learned that P = U * I. So 6000V x 192A = 1.152 MW. How come this motor has even 1.7 MW?
Хороший должно быть моторчик! Молодцы, что сделали!
Большое спасибо за хороший комментарий. Я отправлю это своим коллегам, которые работали над этим двигателем.
Damn a few gears and he can move the hoole city
maybe
Some kind of soft start
I guess that starting this motor is the only 30% of problem. The other 70% - how to stop it securely :)
if it has to be done quickly, then with a round house kick
the other possibility would be a maximum thrust reversal according to Captain Picard
the time traveler would probably go back to the beginning of the video and not let the ramp-up happen in the first place
мне в машинку на радиоуправление такой нужен )
Вопрос в том, насколько велика машина. :-)
While this is an Ex-rated motor running on 6kV, made for running 24/7 and probably much more heavy duty, I still don't understand why these motors are so much heavier and bulkier than the electric motors used in electric cars
For example, the Lotus Evija, Pinifarina Battista and Rimac C_Two will have 1.4MW (probably peak power though), new Tesla Roadster is expected to have 1MW (also peak), the Porsche Taycan can do 0.44MW continously... but these motors probably weigh around 100kg, not 7300kg. The difference won't be just active cooling, right?
Thanks for the interesting questions. Actually, there are many huge differences. For example:
Industry electric motors have a calucalted life time of approx. 40 years continous duty, means roughly 320.000 duty hours.
How many hours a car is designed for? If you calculate 40 km/h as average speed with 5000 hours you are at 200.000 km
This motor has the 1.7 MW at 1500 rpm, the electric car motors at much higher speed. If they have their power at 6000rpm it is only 1/4th of the torque, at higher speeds even less. We have to compare torque, not power.
Our industial motors MUST have extreme overload requirements (by IEC Standard 160% torque for 2 minutes, 190% current for 2 minutes). The given data of the electric cars are just very short peak data, which they can supply for a few seconds.
These are just some of the most obvious differences. Apart from the name "electric motor" and physical principle, electric motors in cars do not share anything with electric motors for industrial applications.
Electric motors in cars are not made for continuous, non-stop use at the full-rated torque and speed. You can also say the same about vacuum cleaner motors, that are much smaller and lighter than their industrial counterparts that have the same power.
I like the music 🎼
We also.
Can you upload video about big electric motor overhauling? Thank you very much.
Thank you for your suggestion. We try to keep this in mind for our next videos.
Awesome!!!
Thank you. The megawatt motor or the video itself? ;-)
4-pole motor, 1,486 RPM @ 50 Hz. so, I would need to run it at 7,200 volts @ 60 Hz, to operate at 1,786 RPM and still get full rated torque?
yes, absolutely correct
@@MenzelMotors That means 2280hp @ 1486rpm translates to 8061 ft lb of torque . Amazing
@Vincent Robinette Your comments are gold and I just have to say that, thank you, I'm glad to have you here.
What about using a Top fuel engine with 1,700kgfm
@@fir3zzz580 Too expensive. Fuel costs ~$70.00 US per gallon, $18.47 US per liter. The engine, running at a reduced speed, (it will indeed produce the torque) will consume approximately 1/2 liter per second, that's $9.12 US per second. Another problem, is that the engine can only sustain that power for 30 seconds at that reduced RPM, then, it will need to be rebuilt. Keep in mind, these engines typically don't have any cooling system. They rely on thermal mass, to allow for a ~5 second run down the track. They use the "burn out" as a means of warming the engine up to a minimum operating temperature, the thermal mass helps keep it from over-heating in the 5-second race. it is then disassembled, gets new rings and bearings, and it's allowed to cool, reassembled in less than an hour, and is ready for the next race.
At $.12 per kWh, the electric motor can run for 22-1/2 hours on the same money, that it takes to fuel the dragster engine for one second. While the engine would need a rebuild every 30 seconds, the motor can run continuous for >3,000 Hours at full rated power, without any maintenance!
The only advantage the top fuel engine has, is horsepower to weight ratio. The electric motor weighs as much as the dragster, and the truck to haul the dragster in combined! Not a problem, in a stationary application. These large electric motors don't have to accelerate themselves.
How can these irresponsible and Germans just build these massive, productive electric motors without any regard to carbon emissions or water usage? I'm glad to hear that their industrial capacity has been severely reduced.
Relax. We build very sustainably and responsibly. Our motors have a very high level of efficiency. We deliver worldwide. Our engines are located in almost every country in the world. Maybe in hers too. Sometimes they are so irreplaceable that hospitals, water supplies and important areas of life use them.
What's the RPM of it?
1.7 MW is too much
we don't think so ;-)
I know you told me to go to the site but could you just give me any value of a squirrel cage motor cost, I need it for simple research, not university research just a simple one, no specific price just the price of a default one or the price you belive it to be please answer this question and thank you for the fast response you had on my other comment, very effective.
Dear megacup3977, thank you for your question. Since we are specialized in the production and delivery of large customized, individual electric motors, there is nothing like a general price list for our motors.
Nous savons rien sur les détails de ce moteur ni sur leurs usage merci
Le moteur a été configuré pour la mesure du niveau sonore dans notre champ d'essai de Berlin. Dans ce cas, le démarrage du moteur a été effectué découplé et sans demi-clé. Les valeurs de vibration et les niveaux de bruit se situent dans la plage de tolérance spécifiée.
Ce projet de moteur électrique concernait une livraison particulièrement rapide du stock. La commande venait d'une compagnie pétrolière européenne où un moteur de pompe était tombé en panne. Le moteur à cage d'écureuil montré ici dans la conception de pied IM 1001 (IM B3) a une construction en acier soudé avec des boîtes à bornes latérales, un bout d'arbre et des roulements à rouleaux lubrifiés à la graisse. Il est conçu pour les zones antidéflagrantes de la zone 2 et dispose d'un échangeur de chaleur tube-enveloppe-air-air. Son circuit de refroidissement par air interne est entraîné par des ventilateurs internes montés sur l'arbre. La chaleur externe est dissipée dans l'air ambiant via l'échangeur de chaleur tubulaire dans le boîtier et le ventilateur externe installé sur le NDE (type de refroidissement IC 511).

I just found your channel. Beautiful motor! But being around 6,000 volts at high current seems pretty scary!
Thank you very much for your nice comment. We are glad you like our channel.
Don't worry, as a company we are committed to the utmost caution and safety of our employees.
1.7 MW = 1.700 kW = 1.700.000 W !!!
thanks for your comment, it's true, that's a lot of watts ;-)
Я такі мотори бачив в Україні на заводі Карпатнофтохім
Мы рады слышать, что вы разделяете нашу страсть к электродвигателям.
Very impressive. I love this.
And we like it when you like it.
Photonic induction would love to get his hands on one of those i bet. Smdh.
Yes, somehow these big motors have a magical attraction!
What is the testing rig for this beast
take a look at our playlist for our electric motor test field ... ua-cam.com/play/PLyNAwc95KEK2jHjYajwDs9Z3NX6LCMlXV.html
put 6 of these together and you can power Boeing 737
... then we need 6 more to compensate for the weight of these 6 ... ;-)
What voltage was used to start it?
Thank you for your question. We start over a VFD, so frequency and voltage from zero on.
They didnt appear to check the bearings.
Why do you think that?
Now attach it to a shredder
This motor was made to drive a pump. But, indeed, we are also manufacturing big size motors for shredders. For example for shredders that are used in the sugar beet harvest or sugar cane harvest.
@@MenzelMotors lol I was joking but if you actually made a motor specifically for a industrial shredder purpose with that size in the video would be insane, would be a 3 phase slow one but still insane.
This 3 phrase motor has any capacitor? 😅
Thanks for your question. No, these large 3phase motors have no capacitor
How much does a motor like this cost
more than a Tesla and less than the downtime of an industrial plant ;)
make this drive a fan
This motor was to drive a pump. But we are also manufacturing fan motors, for example for the cement industry.

Glad you like it ! ! !
Great💪🏾🇬🇭🔥
Thank you. Very interesting videos coming soon.
Must be ridiculously high voltage considering the power lines compared to the motor are the size of sewing thread.
Thanks for your comment. The cables in the test field are suitable up to 20 kV insulation. The thread on most HV motors is M16.
Is this the motor used to rotate the earth ? 😂😂😂
Engines are stronger than motors
Well, that would give us a lot of power :-) The order actually came from a European oil company where a pump motor had failed.
Ничего особенного. Жаль фотки нельзя вставить, я показал бы более мощные российские, но форма один в один. И запуск на реальную нагрузку без частотника.
Да, есть, конечно, электродвигатели гораздо большего размера. Предлагаем двигатели до 25 МВт и 13,8 кВ.
Ok 🇸🇻👍
Thank you.
keine Erdung anschließen ?
Die Erdung erfolgt über geschirmte Kabel im Prüffeld, die als Erdung dienen.
whats the price i need to know very quickly please
The price depends on many configuration factors and varies. It is best to send us a specific request and our engineers will provide you with a concrete offer. info(at)menzel-motors.com
What is the price of the Squirrel cage motors
@@MenzelMotors I don't really want to buy the product, I only want to know the price of the squirrel cage motors, for I am doing research about some electrical motors, don't worry I am citing sources.
Torque?
Rated torque Nm 10925
I hope you phoned national grid well in advance of startup so they could put another power station online
Fortunately the frequency converter of our load machine is regenerative and absorbs the energy for reusing it. ;-)
es klingt jedenfalls wirklich abgefahren, wenn so ein großer Motor einfach stumpf per Stern-Dreieck hochgefahren wird
Magst du den Sound?
@@MenzelMotors ja sehr. Da gibt es ein Video aus einer polnischen Mine wo der Lüfter mit 1100kw so angefahren wird oder ein Kartoffelgrinder mit 130kw. Sehr geil. Der Netzbetreiber wird einen dafür jedoch maximal hassen

Can I come over and try to stop the shaft with my bare hands?
Any time. But I have to tell you beforehand that many have tried and not a single one has succeeded ;-)

Sir the electric motors used for submarine propulsion are of same kind? They also range in 2KW+ rating
Thank you for your question. To our knowledge submarine propulsion are completely differently built. But we lack the details, as this is military secret.
