Very good sir Nice 👍 💯
Super sir nice most useful video 🌹🌹🌹💗👍
Thanks and welcome
Thank you sir for this marvelous clarification on the Back EMF term. Thank you.
सर आप बहुत बढ़िया काम कर रहे हैं क्योंकि इस टाइप के वीडियो के साथ केवल इंग्लिश मीडियम में ही समझाया जाता है
आपके पढ़ाने का तरीका बिल्कुल अनोखा एवं आसान है, जिसे हर कोई आसानी से समझ सकता है। ऐसे ही और वीडियो बनाइए। जैसे- ३ फेस ट्रांसफार्मर और सिंगल फेस ट्रांसफार्मर।
itne dinea baad video diye sir tora joldi di jiye. thanks sir
Very good video sir.Thanks for sharing
Excellent presentation Sir. Thank you.
Thank u. Pls start AC motors video and drive video also
Ok sure
Sir ap ko thanks bolna chahiye key ki ap apna time de kar hamare liye animated video bannate hai thanks sir
Good job bro , keep it up,
Gazab samjhaya sir👌
Very well explained sir
Thank you so much sir 🙏🏻
thanks a lot.
1k likes from my side,
I didn't get this funda in entire engineering
You made it very easy!!
Hi
Thanks to Hindi speech
Nice work sir☺
bhut acha hai sir g
Please keep making videos your videos makes concept clear Sir
Thank you Saurabh sir.
Another informative vdo 🔥🔥🔥
One request, pls make a video on lightning protection system for home. Including working principle & design & which matarial is most effective for the system.
From past 6 months in our dist there is a lots of dengarous lightning happening on almost every afternoon, in my house also , electrical instruments burned 😓😓
Hope you will help
Super video back emf
Thanks
Nice video
Very nice info sir 😊
Thnx bro.. My all doubts are cleared
Really the way u r presenting the animation its mind blowing......
Excellent teaching method.....Aap aur naye video kyu nhi daal rhe hai???
very good video sir
Understand
Thank you sir
Thanks for you
Sourabh Bhai kafi Dino ke baad video bana rahe ho aap. Aap Bhai video banana continue rakho aap ko 1M Parivaar cross karna hai.
Good video 👍👍.

Happy teachers day sir
Thank you so much
Majaaaa aa gyaaaaa😍😍
Hi sir
Can i know which software are using to make this type off video
Excellent Sir
Oh My Good...., I am very much glad, getting appreciation form big big experts! like you sir. I always admire you sir.
Thanks a lot sir
Nice vedio
Sir tranformer k back emf k bare mai ek vdo banaiye
ji
Yes sir
Yes
Hi sir, please make video on HV circuit breaker with mechanism of charging and discharging in animation this will be beneficial for all viewers.
Very nice
Best video
Sir Aapki next video kab tak aayegi?????? Please sir jaldi upload kijiye🙏🙏🙏
Auto cad ki bhi video bnao kese project bnae
Is video me autocad use nahi kara hai, or mujeh abi autocad ki jyada practice nahi hai, future me jaroor is pr work karuga.
Anyways thanks for nice suggestion
@@sourabhsharmahindichannel3000jo apko ata hai wo bhi bta dena or autocad to jarur bta dena is se sbhi students ko help milega

Hi dear friend
What program did you make this film with?
I want to make a film for my dissertation?
Nice. Sir. Star delta stater par bhee ek video please
Banaye
the animation is very nice but the language bro.....
Sir jaise series motor ka btaya vaise hi shunt or cumulative ki characteristics pr b videos daliye.. Graph se related exam me questions b aate hai... Plzz request hai sir
Shunt motor ki characteristic ko ham is seris me cover kar chuke hain. next video me ham compound motor ki characteristic cover karege
@@sourabhsharmahindichannel3000 thank u sir...
Sir , ek interview me yeh sawal pucha tha
___________
Consider an ideal DC motor (where ra = 0)
then Vt = Eb (since Ia*ra = 0)
If 2 points are having same potential then how is it possible that current is flowing from supply to the motor
Pls reply ...
It is very similar to the situation
we always taught that
Motor will run in steady state when
Motor torque = load torque
in case load toque exceeds then deceleration will happen
in case motor torque exceeds than acceleration will happen
so for steady state it is necessary that
Motor torque = Load torque (both must be equal)
it means, Motor torque - Load torque = 0
Then sudden a thought may come in our that if two torques are equal and opposite then why the hell motor is running.
So the answer is the equation written for, or it is describing the working state of motor and it has nothing to do with stationary state.
Ye animation videos le lie aap kaun sa software use krte ho sir please btaae??
Helpful video for every Electrical engineer 👍
Aur bhi Motor k bare me btaoo sir ❤
Sir plc programming ke bare kuch bataeye
As soon as possible
DC generator ke baare me bhi en animation video banaiye 🙏🙏
Kindly make a video on the working principle of ACB & VCB
Sir agar bacf emf lagbhag equal hai toh multimeter per terminal potential difference 3 volt hoga kya
No, jitna apply karege unta hoga, ike agar 200 volt ke motor hai to hame 200 volt apply karna padega motor ko chalane ke liye to multi meter se una hi voltage dikhega jinta ham apply karege.
What is a dc motor? What is back emf?
Isn't it wonderful that when we flip a switch which is wired to a ceiling fan, the fan rotates! Take a moment to visualize the force which acts on the blades to keep them rotating while we are standing on the floor far below the fan. As if it is rotating by an unseen hand!
It operates based on the principle that a current-carrying conductor placed in a magnetic field experiences a force and this is what was encapsulated in the Lorentz force law.
A description of load torque always accompanies a discussion on motors. The effect of its imposition on motor torque, and how this causes the motor to draw power from the power supply then follows. The phenomenon of how it is the ‘back emf’ in motors, which regulates the motor torque to match load torque completes the discussion.
To understand these ideas, it would be instructive to understand Current, the conduction process and Voltage at the fundamental level.
Electrostatics and circuits belong to one science not two as in the following two videos:
i. ruclips.net/video/TTtt28b1dYo/видео.html and
ii. ruclips.net/video/8BQM_xw2Rfo/видео.html
The "back emf" or "motional emf" is a trick nature uses which has a regulating effect in determining the amount of current the motor draws and is a natural consequence of the induced emf process when a conductor moves in a magnetic field.
The fan pushes air and the molecules of air when they leave the blades produce a reaction force, a torque as the blades spin. The fan motor should generate sufficient torque to overcome this opposing “load” torque and keep the blades spinning.
The "back emf" regulates the current to generate this required torque automatically!
The governing relation for current in conductors is J = σE_net where σ is the conductivity of the conductors and E_net is the resultant of the applied and inducedcelectric field components in the conductor.
It is not possible in this post to discuss in more detail the process of production of the back emf and its regulating effect on motor torque.
The last frame References in video #1 lists textbooks 3 and 4 which discuss these topics in more detail using a unified approach and provide an intuitive understanding of the generation of an emf in generators and motors.
good video
Sir hum elevator me power supply jane pr jo jhataka ata hai use kese kam kr sakte hai kya us me DBR device use kr ke ye problem solve kr skate hai
Please provide solution
DBR se to problem or jyada bad jaayegi, kyuki aap jese hi DBR apply karoge motor me breaking torque lagega or motor suddenly stop hone ki kosis kargi, is problem me bachne ke liye kai sare system me fly wheel mounted hota hai.
