"I did the research in English and Korean.... I didn't understand a thing" I love and appreciate your honesty. The subtitles are what makes the video! Thank you.
I enjoy these videos. I worked with and on ships all my life. Korean ship crews were hard-working and professional when I was with them. Korean ships which I was on were well-built. I went to Korean shipbuilders and was amazed by their construction methods. I love the Korean people and the Korean countryside.
Loved the video and cinematography. As always, your comments are on point and bring several smiles to my face. Thanks for educating and entertaining us at the same time!
I began my engineering career over 40 years ago at the Westinghouse Heavy Industrial Motor Division in Round Rock, Texas as a mechanical design engineer. This video brought back a lot of memories.
Worldwide expert here, this is an induction motor and the stator windings (not shown here) will induce a current to the rotor bars of the rotors which will have an opposing magnetic field to the stator, turning the rotor. What you may have come across in your extensive research is sometimes the rotor bars are skewed a little to reduce noise, increase starting torque etc minor things but those are more relevant for smaller general purpose induction motors.
Nice details and explanations. I learned a few things, and I am a retired electrical Engineer. One thing, though, this is a high quality steel, would likely go back to make more of same. Would be a waste for rebar and not likely right for structural members.
That high quality steel took energy and other resources to make. It will be sent back to the steel plant as clean recyclable material, labelled as such and the make up of the steel so they can make more of the same. Rebar and I beams from that these days 😱😱
The high silicon steel sheet makes excellent transformer and motor stator cores because of its high magnetic permeability. It creates an excellent magnetic circuit, and I believe that because the silicone content raises the electrical resistance it has higher efficiency than a carbon steel can. I love the way the scrap from the massive sheet punch folds itself up in the recycling stillage.
I seem to remember from my younger days that with transformers the layering of sheet steel or iron is not necessarily to aid construction but to guide the magnetic flux lines which makes the whole thing more efficient. I suppose it's the same here?
I remember learning some 25 years ago that the sum of all industrial motor and lighting efficiency was so low, it could easily be doubled, effectively gaining whole new industrial capacity ‘for free’. This really intrigued me. What we are seeing today is likely some point in that process which has even found further gains and continues to be a force multiplier in industrial processes.
What I know about electricity can be boiled down in one statement. "Let the professionals do it! Thanks to everyone who contributed to this video!!! Watching from North Carolina USA
So clean and smooth process. Tough work also look like simple and amazing. Stamping of core is just amazing work. Excellent. Need next video how they do the winding. Rotor cooling if any. Or calculation. Love from 🇮🇳 India.
About bars at 6:13 As I understand it, this machine is a synchronous generator (the frequency of the output voltage coincides with the frequency of rotation of the rotor). In such machines, it is very important that the output voltage frequency is constant (hence the rotation frequency is also constant, since they are directly connected). When we rotate the rotor with an electric load connected, we apply a certain amount of torque (force) to the shaft so that it rotates and generates electricity. BUT if the load changes quickly (becomes more or less), then either more force or less must be applied to the shaft. This means that the rotor will start rotating faster or slower (this is acceptable, but within small limits). In order for us to have time to change the force on the rotor with sudden changes in load, it must change its rotation speed slowly (because it is a large generator and something large rotates it - it is difficult to change the rotation speed of something large). To make the speed change smooth, a damper winding of these rods is used. The video does not show, but later they are connected at the ends. This construction is called a squirrel cage (for obvious reason, you can Google =D). Without going into details of all the processes taking place in the generator, this cell is like an electromagnetic spring or an armorizer (as in a car). It does not allow the machine to drastically change its rotation speed. Probably more professional people will explain it better, but I tried to tell everything as accessible as possible and to the extent of my understanding (I am a student at an aviation university, we study only small generators). Sorry for my English and terminology, I used a translator) UPD: i watched further - as you can see at 7:07 this bars welded together by the ends.
This is probably not a direct synchronous machine, but rather an improved High efficiency phase controlled (aka vector controlled) squirrel cage rotor for an induction machine. If you look up the torque speed curve of a squirrel rotor, you can adjust the torque to be high at low speeds (for starting), or high at high speed (least slip, maximum efficiency), or somewhere in between. This is done via the inductance versus resistance ratio of the windings. Since there is no skew in the rotor, this has to be "somewhat synchronous" to obtain maximum efficiency, hence the vector drive. The steel itself has a fairly high resistance, so the copper rods are added to reduce the resistance through the rotor. Usually this is simply done by just pouring in molten aluminum, into the slots, and leaving an end ring. Aluminum has somewhat low resistance, and this allows motors to be made for Drills and Compressors where the starting torques can be very high. Unfortunately once the motor gets up to speed, the slip increases in proportion, and the overall efficiency drops at the higher speeds. Vector controlled motors allow a highly conductive rotor to be started at a slip angle which minimizes the starting current surge. If you had a high-efficiency motor doing a hard-start, the starting current could be 3-to-10-times the normal running current, and if that motor was overloaded and slip-stalled, the breakers would kick out since the current draw would be huge. Vector control allows the slip frequency to be brought up appropriately, to keep the current within limits, and then it tracks the slip angle as the motor speeds up, and then it can place that angle at the "absolute maximum" of the rotor and stator efficiency. As such, it is within a few percent of the incoming line frequency, and is semi-synchronous to it, but with varying slip angles. We designed such systems for ships, combat vehicles, mining machinery, and it is commonly used where a high efficiency process is required, with minimum motor weight and size. For rotary kilns, some of the stators are over 10+feet wide, and the rotor is only a small ring around the heater tube. Repost this if anyone wants more info.
Beautiful and fascinating! I hope we get to see you film at the company that installs the stator and rotor windings. I also really wonder what types of motors these are, and what the application is.
In the early days of electronic computers, up until the 1970's, "Magnetic Core" was a memory technology built out of thousands of little ferrite toroids (donut shape, 1 donut per bit) I guess not too many people remember that usage of the term anymore.
에나멜선은 넣치 않고 처음에 넣었던 구리선이 주변에 있는것을 전자석으로 만드나요 ?? 헤어핀이라고 사용하기도 하던데 .... 근데 그런것도 안보이고 구리선이 그건지도 궁금하고 회전자도 그렇고 고정자도 그렇고 소형 전동기나 발전기에 사용하는 방법이랑 좀 달라보여요 추가 공정이 있는건지 위에영상만으로 끝인지 궁금해요
I was surprised when you said they make rebar and beams out of scrap steel. Isn't electrical steel too high in silicon for that? I remember playing with transformer laminations as a kid and they were so damn brittle, they would crack after several bends and had crystals visible on the fracture.
So nice to see person using traditional skills like adding separators to welding machine (absolutely vital) andbthen essential testing, plus later banging wires with a hammer 🔨, carefully and with precision ❤. Interesting no machine has said yes to those bits. Excellent video and captions yet again. More please
Watching this video I really enjoyed it, increased my knowledge and the machine works very well, it was successful for "Factory...."....Pekalongan, Central Java, Indonesia

I am hoping for this as well. These are beautiful and the windings must be works of art in their own right!
Probably not caz copper are expensive those days.

That would be SiliCON, and element, not SiliCONE, a man made compound.
@@The_DuMont_Network That would be AN, an indefinite article, not AND, a coordinating conjunction.
Si steel has lower hysteresis losses. That's why it's used in AC induction machines.

I suppose it's the same here?

This video shows some serious organic growth. This process was not perfected to this level overnight.
Would love to see winding too.
??? Metal is inorganic. Growth ? And it is a non sequitur to say not perfected overnight. Statement of the total bleeding obvious. WTF ?
Having a moderate understanding of how induction motors work makes this far more satisfying to watch 😂
