No we cannot vary speed of Synchronous motor. All Synchronous motor run on Synchronous speed. But Synchronous speed depends on no. Of pole. So, for example, all Synchronous motor having 2 poles have same RPM.
2.57 but Dear sir I have been seen in my polytechnic practical where dc supply is given to the rotor of the synchronous motor and the rotor is driven by a prime mover 'still the n s magnetic field is locked with ac synchronous magnetic of the field (starter)
Question: Sir agar Synchronous Motor may Rotor speed aor Synchronous speed equal hoti hay matlab k dono aik he speed say rotate karty hen toh According to Slip Formula jab dono may relative speed he baqi nahen rahay gi toh Motor band q nae hoti ??? When rotor speed and Synchronous speed both are equal so how Torque produce???? Why motor can't stop here and why still rotating ??? Plzz reply i have not found any satisfactory answer on youtube.

I'm from Pakistan
U have great knowledge and very helpful for me
Important topic..thnx for sharing 🙏👍
Thank you Samvedna..
All video is Very useful for knowledge and interview.. thank you for being in youtube..
Thank you for appreciating Jeet.
The topics are selected based on interview. I hope this will help all of you in future.
Sir your all videos osm and very helpful Electrical interview thank you sir 🙏🏻
good video..
Thank you..
You are my best favourite teacher
My pleasure Saumya...
Good information
Wonderful sir
Thank you Pramitap..
Your explanation in amazing.
Sir Birla company which type of questions asking in deploma ENGINEERING
I love ur explanation
Thanks sir giving helpful information.
sir hum power plant han un mai kon si motor ka use krty han
good
Nice topic sr
Sarvo motor ke bare me v btaiye sr
Thank you Ankit.
Sir please bata do why we give double excitation to synchronous motor.
Sir IM lagging pf hi kyu run hota hai leading pe kyu nhi?
Parmanent magnet rotar motor explain karen please
Sir agr synchronous motor mei field winding mei ac provide kare to kya hoga
Gajendra dc supply is used to provide steady magnetic field in rotor.
This is not achieved with ac supply.
Can we change synchronous motor with induction motor or vice versa
Hum ko patha hy ki load ki tharaf capacitor lagake power factor change karte hy. Alternator ki tharaf se bhi power factor ko change kar sakte ?
Haan kar sakte hai.
Power plant mein AVR se control karte hai
which motor is best Dc or synchronous motor and why?. torque and power consume the same load
Mr. Joshi your explanation is awesome and it’s beyond expectations.
Thanks for such a good videos.
Please make a video on each and every transformer testing.
Factory and routine test.
Thank you so much 🙏
Thank you Sir,
Make video on Servo motor in depth
Most welcome Alok..
Okay 👍
Also watch playlist for videos related to Drawing, Calculation, Motor, Transformer, Power Factor Correction and many more.
1 :
can we speed control of synchronous motor ?
2:
different between dc motor and synchronous motor
3:
all synchronous motor are same RPM ?
No we cannot vary speed of Synchronous motor.
All Synchronous motor run on Synchronous speed. But Synchronous speed depends on no. Of pole.
So, for example, all Synchronous motor having 2 poles have same RPM.
Exatation system se pf kaise maintain krte hai
Excitation current vary karne se pf vary hota hai. AVR ka use karke ye kiya jata hai.
Pintu, also watch playlist for videos related to Drawing, Calculation, Motor, Transformer, Power Factor Correction and many more.
Why we use voltage multiples of 11 kV?
We will make video on this.
It is difficult to explain this concept in message..
@@electricalwithabhishekjoshi ok sir
Sir, how we can verify visully
2.57 but Dear sir I have been seen in my polytechnic practical where dc supply is given to the rotor of the synchronous motor and the rotor is driven by a prime mover 'still the n s magnetic field is locked with ac synchronous magnetic of the field (starter)
Plz tell about DC excitation panel
Sir 🙏 dc excitation ka roal nahi samajh me aa raha hai
👍👍
Thank you KK..
How rated motor use in your industry for cement mill...🔥
Atul we have 5000 KW motor in Cement Mill.
@@electricalwithabhishekjoshi OMG🔥
AND WE HAVE 900KW MOTOR FOR CEMENT MILL...
Good..
Thank u sir
In Synchronous motor rotor why not inducing emf by mutual induction
How to excitation improve power factor of Synchronous motor ... please explain without math
👍
Question: Sir agar Synchronous Motor may Rotor speed aor Synchronous speed equal hoti hay matlab k dono aik he speed say rotate karty hen toh According to Slip Formula jab dono may relative speed he baqi nahen rahay gi toh Motor band q nae hoti ??? When rotor speed and Synchronous speed both are equal so how Torque produce???? Why motor can't stop here and why still rotating ???
Plzz reply i have not found any satisfactory answer on youtube.
Synchronous motor is work on the principle of magnetic loking. So this is the reason why rotor rotate .
sychronous motor or induction motor ka use kahan hota ha
🙏🙏🙏🙏
Thank you Saikumar...
Ye kyo hota he uska koi explanation do….
DC in rotor,not in stator of synchro

Synchronous motor works on magnatic locking, not on mutual induction, so zero relative speed not affect on motor operation.
