Thank you sir ji knowledge full video
So nice of you. watch other work too
Nice explanation sir.
Thanks. Keep supporting !
Super explaination
Glad you liked it
Thinks very nice video
Thanks to you
सुपर क्लास सर थैंक
keep watching
I learn lot of
thanks
Best
So nice of you
Very good description ! But Sir please provide a servo control practical circuit with transistor or IC circuit ! Thank you Sir !
Ok I will try
Whatss app number sir
My Whatsapp No. 9437457989
Sir, mujhe 3 phase servo stabilizer banana hai.iska formula kya hai,
Ex-20kva, stabilizer
Input Range -340-480V
Output -415V
BBT Rang- ??
Dimmer coil Amp- ??
Kaise calculate karte hai.
Hello! When i turn on my servo stabilizer, it doesn't turn on but makes a humming sound even after removing the output line from the stabilizer. What could be done please?
motor controller circuit has a problem. Check brush position on auto transformer tapping too.
Sir
When i open most of the stabilizers i found one of the input voltage terminal is directly connected to the sliding brush
That means not as u explain in the diagram
Why
Check your observation once again. We have discussed what actually is used and manufactured.
Sir mere studiomaster SVC 10000 me high voltage ki light lagatar jal rahi hain kya problem hin sir bataye
feed back loop is not working or brush of autotransformer get jammed
Hello sir, I have also tried opening my avr and trace the input voltage and found out the other input lead is directly connected to a sliding brush through a fuse and three pin switch. Following your diagram I could not find the buck)boost transformer which leads me to suspect that the buck/boost transformer is wound in the same core as the toroidal auto transformer is wound. Is there another configuration? Thank you
You are inspecting a simple automatic electronic voltage stabilizer and not servo stabilizer. check our video
th-cam.com/video/QZXP05YmUk4/w-d-xo.html
Some servo use dimmer (toridal autoransformer) only
Good jop
Thank you

sir g, ye bataen k stablizers mein sub say stable aur acurate output voltage with fluctuation ya pure wave walay konsi stablizer technology ha? single phase mein
servo is the best
@@ShreeDeviClasses why? 2nd question, meray pass servo stablizer ha jissay mein nay input voltage 179volts de aur output 218volts milay, input wali wire pa clamp meter pa 5.2 amp show ho rahay thay and stablizer say out wali wire pa 1.5 amp show ho rahay thay, sawal ye ha k 3.5 amp difference kyun ha input n output amp mein, kia ye efficient servo nahin ha ya koe aur waja ha?
Reply..my servo main mcb tripping...when on...possible due to duck boost transformer internslly short?? Because when it wire disconnected servo motor work but voltsge low out put..so pl guide
disconnect load and connect only stabilizer to supply and revert your conditions.
Without load supply mcb tripped
problem may be with internal wiring and insulation. Check it as transformer are designed too rugged and usually remain safe.
the problem is with wiring and some insulation need correction.
Bhai 140 volt input say 5 kva and 10 kva buck boost transfarmer ka data bataey thanks

How to design buck boost tx & auto tx & tap
VA rating depends on correction limit. for 180 to 280V input and 230V output it is 50V for rated load current. i.e. for 10 KVA servo buck-boost transformer is 50/230 x 10 KVA. Turns ratio and tapping position is interrelated. Please view our video on machine design related to transformer design.
@@ShreeDeviClasses Is turns ratio for BB 1:1 ?
Sir Aap input 250 sa output 400 Kar sakti Ho 75kva ka stabilizer hai plz help
If input is always near 250V and only 400 V is required at output then there is no need of servo a simple step up transformer will do.
@@ShreeDeviClasses sir hamra pas MA Eka stabilizer hai 3 phase uska degine input 320 Sa hai usa kaisa input 250 sa kiya gaya plz help
बक बूस्ट ट्रांसफॉर्मर कैसे डिजाइन करते हैं
its VA rating is proportional to correction required. If lowest input voltage is 200V so for 230 V rating it is about 15% of output. Turns ration and primary conductor size depends on fixed tapping on auto-transformer. The secondary conductor size is as per load current.
If you need detail description we can prepare a video on this design aspect. Please do visit out electrical machine design playlist.
Cut off ka solution btaye
either limit switch or relay may be used
Servo m 90v - 440v ka nahi aata h kya
it is possible to design this servo for 230V output. but such input voltage range is practically not available.
What is the best way to purchase servo stabilize r to avoid duplicate product in the market????
poor quality products are usually under rated and can be checked by a load test of 30 minutes.
Thanks. Do view other videos and also share them to friends to spread knowledge and channel work.
Namaste Sir, me telangana se, mere keth me transformer se 260v arahi hi, is vaje fuse aur auto switch burn ho rah he, ab is voltage ko 220-230v me kaise karna sir, please help🙏🏻.
take servo on manual mode and decrease output. if controller is not working than disconnect servo and get it repaired. If you got servo and input is 260V than it will correct voltage and very useful for all motor loads. Please mention your electric load for better understanding of problem.
@@ShreeDeviClasses we are using a 5hp motor with l&t mk1 dol starter sir, our transformer is using only this single motor, our technician said because of high voltage motor bush bearings are wearing out, don't run the motor for excessive time.
Please suggest me all the components which I can add to it sir which can make it work perfectly with best efficiency, It is very important for me sir.
Please help sir🙏🏻.
Tell me supply voltage magnitude and working of servo stabilizer. If servo is non-function and supply voltage is regular at higher side i.e. above 420V in line and 250V in phase than you can complain distribution company. If it is fluctuating than mention the lower limits.
Your motor can work in the limits 400V +/- 20V in line voltage without trouble, without stabilizer.
Please also mention the motor mechanical duty or load nature and loading in percentage.
During small overvoltage generally motors are safe and there is no problem of overheating. I can suggest you confirm solution after required details furnished by you.
Sir servo stabilizer ka pdf do.
TH-cam me clear dekhai nahi deta, plz dir
available in description
Sir Please tell me.🙏. is Stabilizer business going to end in future?
No. servo stabilizer will continue in there application and there is no threat as such from present day power electronics technology.
@@ShreeDeviClasses sir because there was a time when the voltage was slow but now the voltage is good and stable so that's why I asked you and I'm learning about stabilizer manufacturing and I want to do business of stabilizer in future
