It might be surprising to know that in electric trains, the power collected from the overheadlines ends up in the grounding cable of the track after flowing through the wheels. Three phase power conversion, regenerative braking and zig-zag overheadlines – all these make electric train technology quite unique. Let’s understand all the engineering secrets behind the electric trains starting from the simplest design possible.

Imagine if the motor bearings damages or motor winding problem came while train in running
How can I make a vedio like this
I mean what should I leran to meke it
Excellent work…
Ultimate 😊
Is an electrical high speed train much more energy efficient comparing to diesel engine standart train despite going much faster?
If current flows through tracks how does it not shock anyone touching it?
love your videos!!
Thanks!
What happens if power goes off when the train is moving?
Thank you very much for the insight ❤

I invented industrial Faraday cages to stop the eddy currents to pipes underneath to …
Well done. Right on track
Awesome contents! I liked it!
Electric locomotives are ideal for commuter rail service with frequent stops. Electric locomotives are used on freight routes with consistently high traffic volumes, or in areas with advanced rail networks. Power plants, even if they burn fossil fuels, are far cleaner than mobile sources such as locomotive engines.
Why does current always flow to the next ground terminal on the rail?
Isn't it like current always take the shortest path for min resistance?

Got my Faraday cage under that stop eddy currents electrolysis
And the locomotives also have a passenger cabin for reverse advantage (0=locomotives (with passenger cabin) and 1= passenger cabins)

How are this animated videos made ???
Folks you can make your pre existing alloy engine run for free simply place magnetic caps on top of each piston and replace the valve head with either a magnetic head or electromagnetic head NEVER PAY FOR FUEL OR ELECTRICITY AGAIN
I think using electricity and AC motor as power-supply is not a green way,waste more than use,in future,I DC motor and bettery will replace it ,like e-car trend
Excellent presentation
6:20 When the rotor speed exceeds the synchronous speed (also known as the Rated Maximum Frequency – RMF speed) in an induction motor, it leads to a phenomenon called "slip." The slip is a critical factor in determining the speed of the rotor concerning the synchronous speed.When the rotor speed becomes greater than the synchronous speed (RMF speed), the relative speed between the rotor and the magnetic field (RMF speed – rotor speed) increases. Consequently, this results in an increase in the relative speed between the rotor and the stator's magnetic field.When an induction motor operates at a speed greater than the synchronous speed (RMF speed), which usually happens during overhauling or deceleration, it doesn't exhibit re-generative braking on its own.Re-generative braking involves converting the motor's mechanical energy back into electrical energy, which is typically achieved through specialized systems like regenerative drives or controls. These systems can harness the excess energy produced during overhauling or when the motor speed exceeds the synchronous speed, allowing it to be fed back into the power supply or storage systems.Therefore, in the context of an induction motor running at speeds exceeding its synchronous speed, without a dedicated regenerative system in place, the motor itself doesn't engage in re-generative braking. The excess speed would generally lead to increased slip and might pose risks or challenges related to the motor's operation or mechanical stress, rather than directly causing re-generative braking.
Little errors and adjustments aside I do really commend this video for the explanation. Surprisingly difficult to find an example of how these machines actually work instead of a more generalized "pantographs and bogies" shallow overview. This was exactly the kind of thing I was looking for.
I want to meet whoever invented this and shake his hand because that's some wizardry over there
THATS soo cool wow
So the tracks arent save?
Wonder how many sparks the pantograph makes
Awesome video
isn't it terribly inneficient?
25kV AC goes through 1) step-down transformer 2) rectifier 3) 3-phase inverter and then finally to the motors
Harwired no batteries needed
HOWEVER
6:50 this is wrong explanation. You can't brake a train by pumping more electric energy into the system. Electric brakes works very differently. The motor generates electricity that is used to heat the brake resistors.
Disc brakes are used these days not shoes for high speed rail.
Great content. Now we can start our own tram company 😂🚊
Jai shree ganeshay namaha 🙏🙏🙏
thank you sir
some things have been forgotten, there are 2 brakes, the "train brake" and the "Ind. brake", which work slightly differently being the same brake, and in my opinion a very important thing, the air tank. The pressure of a long train will take forever to regain enough bar to release all the brakes without a tank to store that compressed air in the loc. In other words, without it a long train will brake and take a while to manage to speed up again
Also, Just Want to add, This May Depend on different trains, but the electricity isalso sent to the coaches and supplied throught the train for other porpuses too
You say the current returns to the power supply through the rails, so for example, if a person stands in front of a train, will that person be electrocuted? And specifically, where do electric currents go when they enter the ground?
Great efforts to explain as spoon feeding. Well done..
