Dear Abhishek ...I like your knowledge sharing video...pls make video on electrical questions video ask during gulf countries interview for petchem company profile..like Aaramco.
Sir please vfd parameter ki detail information or kon sa parameter kis function le liye use hota hai or use change Karne se vfd ke output me kya change hota hai uske bare ek ek video banaye 🙏🏻🙏🏻🙏🏻
Sir , till DC Bus Section of VFD , We get the Smooth DC . Then Square Wave Polarity Changes in the O/P of Inverter ? Is it through Switching of the IGBTs only ? One more question ; Rectifier Section of VFDs is of Power Diodes or Thyristors ? Which particular Section gives O/P in the range of 650 V DC & how as Rectifier Section Input is 415 V AC only ?
Sir bohot jaga likha reheta ha vvvf drive motor usme construction wise yea principal wise kuch difference ha keya please bataiyen.. Love From ❤️ PRAKASH ❤️
But, Sir we are using normal induction motor below 30% of motor speed by fixed separate cooling fan in motor NDE side. Is it okay or required vfd motor?
we have 7.5kw rating current 17.9A, 725rpm VFD motor . (Note when run by VFD then running current 7.2A) if we run by doll starter then running current 14.1 A is there any problem ?
Sir, ek 20hp ka induction motor hai usse ek 25kw ke vfd main connection krna hai motor ke wire ko star connection kr k vfd main 3 wire ko jorde ya delta connection kr ke jode. Pls help me.
Hello,Apane minimum speed of motor 1500bola badame 30%frequency kam ki, varable frequency drivese 1rpm se maximum rpm le ja sakate hai, isaka upayog heating furnace me kiya jata hai.pls check it.
@@electricalwithabhishekjoshi I watch that video but I need something else, I am looking for motor winding data calculation, related to "Electrical Machine Design". Like winding data, conductor selection and calculation, conductor turns, pitch, number of turns etc....
Great dear , please keep it up your sharing klowledges

बहुत-बहुत धन्यवाद सर आपका आपने बहुत ही अच्छा जानकारी दिया इसके लिए हृदय से आभार आपका 🙏🙏
Sir aap bahut aasan tarikese explain karte ho.
Thank you Prashant..
Please make video on the internal configuration of VFD i.e. how inverter actually works with PWM
sir, please make a video on difference between symmetrical and unsymmetrical faults

Hello. When ext pot is used to contril motor speed is there a criiteria for the length of cable between Vfd and ext pot.
Dear Abhishek make video on Bus coupler independent/Mannual/ Auto mode interlock and tripping contact and circuit.
Nice sir,
Valuable knowledge given by you
Great knowledge for me.Nice Sir
My dear sir I like your topic very much and I give you so much thanks very much
Most welcome.
Hello Abhishekh ji..Agar VFD ki speed is not in proportion with d 4 to 20mA output frm DCS then how to rectify this problem.

Construction wise difference hai Prakash.
Mainly jo winding insulation rehta hai, wo jyada achcha hota hai.
@@electricalwithabhishekjoshi thank you sir
सर VFD हमे क्या क्या PROTECTION देती हे उसपे एक विडियो बनाए🙏🏻
Okay Barad..
What about insulated bearing requirement in VFD driven motor? Are u not considering it to run std motor on VFD?
Fully knowledgeable video 🙏
Multilevel inverter
Types and short explain 👍
Sir vfd k out put voltage kese check kre.aur vfd OK h ya ni
Is there any difference between vfd and standard motor, accept winding insulation.
Low frequency explained, but what about higher rpm please explain
Sir VFD k ander Motor Mode kya hoty
Aik DTS
Or Sacler hota h
Sir, wattage is electrical power or mechanical power ? 👈 This ask my interview question
vfd suitable motor aur vfd compatable motor ke bech me kya diffrence hai?
Sir kindly make a video on line charging procedure in thermal power plant
What will happen to ampere decreases or increases for 400KW 990 RPM motor if frequency is below 30 percent
What is the cause for Bus fault in profibus communication system, please explain me
Sir electrical drawing kaise read karte h ye bhi sikha dijiye plsssss..
But, Sir we are using normal induction motor below 30% of motor speed by fixed separate cooling fan in motor NDE side. Is it okay or required vfd motor?
Sir vfd 50 hz motor ko 100 hz ki frequency par chala sakate kya?
Sir can you make a video on internal circuitary of drives with function ?
Sir ji IMCC aur SIMOCODE pe video banao
Nice video
Kya sir invertor duty motor hain kya ye name plate me likha hoga
Sir, on 30 percentage speed of 3 phase 440 voltage system,how many terminal voltage will rise?
Cg 2.2kva ac drive speed kam karne se motor ka turqe kam ho raha hai bataiye kya
Kya normal induction motor ko external fan (like table fan) laga ke cool kar sakte hai kya ?
Why induction motor failed with vfd mostly. What is solution
Sir.. One video..
. @@.. Why transformer frequency not change?
... Please🙏🙏
Sourav, I have made a video why frequency is kept constant.
Kindly watch that video.
Ok sir..
Your videos are really good.
Sir please tell me VFD moter 20%and 1500 = 1200 rpm normal moter 30% rpm 1500=1050 ok good condition VFD moter ya normal moter sir
Sir vfd se agriculture motor submarsible rpm 2990 hota hai kya
Imcc panel aur Simocode par video banaye please
Good job sir
Thank you Roni..
Soft starter vs vfd starter me ek video plz
Sir
Please make a video about vfd setting
Agar hum motor par extra fan laga den to theek rahega?
we have 7.5kw rating current 17.9A, 725rpm VFD motor . (Note when run by VFD then running current 7.2A) if we run by doll starter then running current 14.1 A is there any problem ?
Rated RPM of Motor can't be 1500RPM...it may be 1470,1475 etc ( LT motor) and 1485,1487 etc ( HT motor)...
Hariom you are right.
But bolte waqt waise hi bolte hai..
@@electricalwithabhishekjoshi I learnt lot of things from you.👌👍
Thank you...
Rated speed always less than synchronous speed, because slip is need for induction motor
@@bch2780 slip means rotor speed must be less than synchronous speed
Sir please reply
Kya ham 30 percent of rared rpm pe motor ko full load ke sath le ja sakte hai
Yes. But it depends on insulation class also. Because high load in low RPM results into Abnormal heating.
Sir can we convert single pH to three pH with vfd
Sir, ek 20hp ka induction motor hai usse ek 25kw ke vfd main connection krna hai motor ke wire ko star connection kr k vfd main 3 wire ko jorde ya delta connection kr ke jode. Pls help me.

Hello,Apane minimum speed of motor 1500bola badame 30%frequency kam ki, varable frequency drivese 1rpm se maximum rpm le ja sakate hai, isaka upayog heating furnace me kiya jata hai.pls check it.
Bilkul le ja sakte hai.
But mai ye bata raha hu ki below 30% Motor ki cooling effective nahi ho Pati.
How to motor frequency increases &decrease so effect of motor current
Very good video brother
Great vdo sir
How to apply in Birla group of Companies????
maximum speed kitna kar skte hai normal induction motor main
Hello Abhishek sir, can i apply for internship in your company ,i have completed my diploma.
tnx sir is topic ke liye...
Most welcome Shivam.
Sir ap drawing k sath vedeo banaya karo
Very informative
I have 100 hp ind. Motor 1475 rpm,
Motor speed increse and decrease by vfd so problem is that motor vibrate more .
Please suggest
I think bro you have to make foundation of motor more heavy and stronger
I think you have to make your motor's foundation more heavy and strong. Bulits should be bigger and tighten them fully ....it may relax your problem
Make a video on Motor re-winding
I have made a video on impact of Rewinding on motor efficiency.
Kindly watch that video.

We have ABB motor of 125HP RPM 990, How Much capacity VFD should be installed
125 hp vfd
It depends on application, for ex if use high starting torque may be we have to select VFD that have higher output current
Use full video
Thank you..
Good
what will happen if we run blower on 10Hz?
Blower is less torque at low speed , May be no need to install force fan
940 rpm ki motor ko 12.5 HZ pr chlate h
Thanks 👍
Pata hi nhi tha ki ye bhi hota hai
👍👍
Good video
Good info
