that motor has to have some serious bearings
yes
Some serious wiring as well.
Serious balls you say? Correctomongo 😉😆

Probably just a set of tapered roller bearings on each end.

1:08 Notice the 'field weakening' at higher speeds. At higher speeds the back emf becomes sufficiently high to impede flow of current into the rotor winding, thus reducing available power. So field current is reduced to keep current flowing into the rotor.
Explain in more detail please, especially what current and field current is
@@AbdulRaheem-ul6kp i think its like an upgraded resistor but i dont think it is
The motor becomes a generator when power is not applied..
To keep the current flowing is to power it up a small amount to cancel out the power it produces when the motor becomes a generator.
You can also exploit this anomaly by sending the generated power to a resistor bank. Large resistor bank can absorb a lot of power requiring the generator motor to exert more force. Said force counteracts the inertial motion of the locomotive slowing it down. The dynamic braking principle is born.
"counter EMF"
@@kimpatz2189 in layman's term - it's creating a perpetual movement enough to power itself and also to save the incoming energy through its motion! Am i correct??
I never realized how much power went into these things. I mean, 1350 hp seemed reasonable for a motor that size, but I never converted that to wattage in my head as a comparison. At full chooch, that would be the equivalent power of around 1000 homes! And that's just one of six?!
Yup, lets put one in my car 👍

yep and it takes 2x 5000 hp electric motors to refine fiber length for paper. 16 inch diameter shaft, about 15 feet tall. A large mill that makes paper for magazines could have about 10-12 of these refiners each with 2x 5000hp motors, talk about power bill.

@@abhinavmadhu9668 wtf
How come they leave the train idling for hours sometimes I know about
@@jasonjamrs7413 I'm not an expert by any means at all, however I have worked with some fairly large engines (not trains) so will make an educated guess.
I'm assuming it has something to do with either piston size or the generator, they are pretty heavy and leaving heavy moving parts sitting in one spot for an extended period of time can cause massive amounts of damage just from the weight of it.
Hydroelectric powerplants like the ones you would find in a few major dams have to TAKE power from the grid at all times even if they arent generating any to replace it because if the massive multi-ton turbines stopped spinning for any amount of time they would have to be replaced entirely as the weight being in one spot for even just a few seconds is enough to crush the bearings that allow it to rotate.
So, best guess is general maintenance? Trying to stave off wear and tare and corrosion?
Just love the sound of those big electric motors starting up.
There's a train in France (Z20500) that somehow has these sounds amplified to the point that it legitimately became it's signature

@ with a blender
The Devel Sixteen could give you 5,000 reasons why..
It isnt that hard, turbos and nox you know. The problem is having 1000+ hp and not exploding or catch on fire due to overheating, the chiron is packed to the brim with radiators to avoid that for example, electric engines generate much less heat so it becomes much easier, cue the dozen or so 1000+ hp electric supercars popping up, really there is no limit to how powerful a electric car can be made, but i dont know anyone who crave a 10000 hp supercar.
I've underestimated how hard these motors work until seeing as well as hearing them, I knew they were powerful but I didn't realise they were this powerful, it's cool to see the contactors and switchgear working too

I appriciate the difficulty in making video's like this. Thank you for this excellent example. 1.4kA at all the way up to 60km/h!! No wonder that thing was accelerating like a bunch of kids to the pizza at a birthday party.
All trains will typically draw stupid amounts of current at departure, it's the nature of electric motors to draw higher currents at low speeds. There's different types of technology around these days to make the engines draw smaller amounts of current while still providing an immense amount of power to get away as efficiently as possible.
Mechanic field weakening is an older type of technique.
@@Dutch3DMaster Yeah, under normal conditions the current would drop much sooner than it did here. Unless they are pulling quite a load.
What a great shot of the traction motor and electric installation;)

White wheel and big wheel from copper is for transmitting electric energy to the rotor?
Ohms Law tells me the voltage is 600 Volts DC for those who wondered.
ive seen videos of mechanical field weakening and heard of it being done electrically, but never actually seen how it was done. i learned quite a bit!
Thank you for sharing these insights! I'm learning from it. I love that.
That's some serious acceleration even while hauling light weight. Great video! Have liked and subscribed. Cheers from India.

Great video, that motor is a torque monster, very impressive.
Must appreciate the camera man for bringing us such footage.
I can tell you it is quite something when you push the acellerator forwards in a train and you watch it pull 700 amps from 16 kV, thats a lot of power! In sweden we have GFCI on the supply line voltage, that sounds like it should protect idiots from bbq themselves, but it trips at like 45 amps...
Very informative and well done. I learned a lot. Thank you!.
Great video! Big LIKE ;)
Absolutely brilliant video, thanks for sharing
Awesome video with great descriptions of what's going on!
This exactly explains the speed-time curve for the main-line service locomotive.
That sound omg iloveit
So, the faster motor spins, the lower amps running through it. When amps drop below 900A, you hit field weakening stage-by-stage, and it allows to boost amps back to 1000A. And prolongate the acceleration. Like a gearbox. I'd never understand it without such an informative video!
thanks for this video, we also love electric motors

The serial production version Rc1 of the Rb prototypes (the Electroputere 5100, this machine) accelerates to 100 km in less than 10 s so yes an electric locomotive runs away very fast if allowed to (tractive 275 kN). The 5100 has even more tractive power (412 kN or soo...)
The 5100 were built for the mountains in the Balkans.
Neat to see the transition in operation!

Fascinating to watch, and it makes me want to see two similar videos:

Nice view and editing
Great video
Thank you for posting
Muito bom.
Between Kiruna (Sweden) and Narvik (Norway) as the train is loaded with iron malm it decent into Narvik harbor the train's energy goes back into the grid.
All modern locomotives and trains have done this for the last 30 years or so now. But I read somewhere that the full iron ore train going downhill to Narvik generates all the energy that the empty train going uphill needs. So in total they use almost no electricity at all and the trip is "free".
Sound and track both awesome 👌👌
Very cool conception a video. Thanks for posting.

What locomotive type is this? The air pressure valves looks very much like swedish ASEA YBL8-valves and the main contactors looks like ASEA EJD 1100.
ASEA patented, Romanian built LE5100, modernized by Concar.
I thought it looked familiar in some way :)
I thought it was an ASEA locomotive because I saw that amp meter that is the same in our Croatian series 1141 ASEA locomotives. :D
I think it should be Koncar... :)
Its front remind me someway the style of the glorious italian E444 tartaruga (before the revamping). Beautiful machine anyway!

Nice video. What is field weakening?
It's the last metod to increase the speed and torque of a DC motor when the voltage regulation has reached its maximum voltage.
Thanks
The DC motor here is a series wound machine, that is the field and armature windings are in series with each other. A permanent magnet (PM) motor uses magnets to generate the magnetic field instead of field winding coils. Anyway, once you get a series motor up far enough in speed the you basically run out of voltage to get the motor to further accelerate any further due to the back EMF of the motor. Field weakening reduces the current in the field winding which allows the already available motor voltage more 'room' to accelerate the motor further. Shunt and compound wound DC motors don't have these issues so much, but they also do not have the zero speed torque capabilities that the series wound motor has.
You can still find series wound motors in use today in your cars electric starter. Pound for pound you're hard pressed to find another motor type for the cost and simplicity of control to provide this kind of torque abilities.
I'm actually surprised there wasn't more flash from the contactors on this run. Very nice video!
Thanks also
When the train is running on a horizontal way,there is not need of high pulling force.So why magnetic field of the engines get decreased and the speed - increased.
Put that motor in a car and you have an electric Koenigsegg lol
The what? Anyhow, I think the bottom of your car will sit on the road surface.
Very satisfying.. awesome capture man...
Amazingly informative channel
Souvenir d'un voyage en cabine de TGV. Très impressionné de voir l'ampèremètre grimper à 6.000 A sous 25 kV au décollage de la rame !
L'amperemetre montre l'intensite du courant secondaire (1500V) et pas le courant primaire (25kV).
6.000A sous 25kV donne 150MW ce qui est environ la puissance d'une petite turbine d'une centrale electrique ;)
Si je me souviens bien le TGV a une puissance continue de environ 6MW ce qui donne 4000A sous 1.5kV
Very good.What loccomotive is that?BDZ class 46,yes?
ventsi002 Yes it is
But isn't it AC locomotive? There's no DC catenary in Bulgaria as far as I know.
@@PrekiFromPoland The locomotive has a transformer with taps which reduces the AC voltage, a full bridge rectifier that turns AC into DC, and then it uses DC to power the 6 (or 4) DC motors on every axle.
@@velikiradojica Interesting, in Poland there's lots of vehicles that do the opposite - convert 3kV DC into AC voltage via an inverter.
awesome video, my favorite part was the click before it moved.
Not sure exactly what I’m looking at but it’s definitely bad ass!
I'd like to know what size conductor is feeding that motor, as well as how it's terminated
The DC traction motors for EMD that i worked on were around 500 kcm. they usually have glad hand type crimps. They fit tight...
+ackmino That must be an absolute bear to work with, damn man
+Jack Duno. locos use extra thin strand wire so its not that bad. Working under the loco is awful and you are always banging your head on stuff. its filthy down there. I have changed motor brush holders in place and that will test your patience. we always managed to get it done though.
Bill of this motor is extremely expensive 😅😂

Its HV so it not consume that much Amps.

Extremely interesting !!! I've never seen this viewpoint before ! Yes, like the others, I love the sound too. Aarre Peltomaa
Electric cars have 70 years of diesel locomotive tech behind them. The batteries are the only new thing about them.
That and the 3 phase ac motors controller by advanced electronics.
Motor controllers that convert DC to 3 phase AC have been in use in trains since the 1980s in The Netherlands, possibly earlier in other places.
What is the purpose of the field weakening?
In a nutshell, it's an electrical alteration to achieve different operating properties from a Direct Current electric motor. Someone else asked the same question 2 weeks before you did in another comment, and there is a fantastic response comment to that question, explaining in good detail how it works. Browse thru the comments to find the question asked by a commenter named Jim Colleran, and below it you will find the response from kleetus92 explaining what it is and why it is used.
Not only for DC-motors, you can apply field weakening to any electric motor (although it's not always necessary to use it). Simply said, weakening the magnetic field in the motor allows you to trade torque for speed. In this old heap they use it in three fixed steps (modern drives can do it continuously/without any steps). As the speed increases here, they weaken the field sequentially in 3 steps (much like changing gears in a car).
The used motor is a series motor which means that the field and armature are in series.
Once the locomotive reaches a certain speed the field is shunted (parallel resistor). This will "sacrifice" torque for speed.
Skip all the bible stories above. The only thing you wanted to know that it’s the electric equivalent of a gearbox.
Thanx for the vid, I'm hopping around trying to find a GE DC-600 drive/ traction motor setup. I used to set up these drives. Cool history. These days Flux vector AC variable freq drives are the rule.
Thanks for the beautiful video.
I’ve never seen a locomotive operate with the wheel in diagonal position before. 🤔
Bassotronics wdym diagonal
the wheel is not diagonal
@ *gυяυвυlυ •*
Don’t you see that everything is straight except for the wheel?
@ *Calvin Junge*
Well I can see that the whole mechanism is straight except for the wheel. 🤷🏻♂️
Bassotronics hm yeah I guess you're right it does sit at an angle... Not sure if I would call that diagonal but it's definitely angled
There's one of those on every wheel of the engine, otherwise the one would break traction and spin, right?
Impressive video
Not necessarily. You have to figure in if it’s wired in series or parallel or series parallel. Some systems have anti-slip control so whenever a wheel breaks traction the motor stops or backs off.
John Tapp :Hello. Has it actually been a year since I posted this? Wired in series OR parallel I understand. Series Parallel would be series, but with two , or extra heavy, wires which can handle the load of hill climbs or heavy acceleration. Is braking done with electromagnetics? If so, possibly creating the heaviest demand?
Was this tech stolen and abused to make the prius? What a waste that would be!
Contraband Fan by Mark Burns First of all, I’m no expert. Second, there are electromagnetic braking systems on some but not all of these locomotives, in conjunction with standard air brakes. One such system is called regenerative braking, where the traction motor wiring is switched so that the motors act as generators, and the power generated goes out through the line and is used by other trains. Dynamic braking, although much like regenerative, only goes through resistance grids-diesel locomotives so equipped use this method.
I doubt very much Prius borrows much if any technology from trains. The demands on both are very different and wouldn’t be practical above or below a certain size.
John Tapp, regenerative is the term I was looking for. Very edficient! This must be why idiots, mostly libtards are removing railways. Two lines have been taken out here in Indianapolis, The Nickel Plate and the Monon, one of which is now a greeeeeeeeenway, the other having no rails left, and no trespassing signs at all road crossings. It is tempting to drive the rout and test my 4X4 just for a laugh. I was being sarcastic about the prius, and I would not have one, unless I could equip it with a big block V8 and 4 on the floor, The snotty imported, smug driver having, eco wannabe, unicorn clown cars. HAA!
Contraband Fan by Mark Burns pound for pound, freight by rail is more efficient, uses less fuel, costs less in overhead, and when stack trains along with intercity trucks, can be very viable transportation, along with freighters for import/export. The idiots out there just don’t know you can’t throw away a transportation mode just because it sounds like it may burn more fuel. Actually, trains burn less fuel, and are ideal for huge land masses.
This is scary af and interesting at same time
