Can the formula at 8:00 be used for output reactor (from VFD to motor)? What frequency do you use? My motor goes from 3000RPM to 18,000RPM (so 50Hz to 300Hz). Do you use 300Hz for calculation?
dear sir our plant maximum drive motor....drive input use line filter and drive output use choke filter( some motor use only output choke)....when we use line filter and haw its work ???? plz details explain....see from bangladesh....
Very informative video I have V3F drive, Controller, 5hp motor I want to use Inpute AC choke To protect Drive 5.5kw and for 7.5hp motor) Which input choke should I use? Pl. Suggest Best company and its model Thank you!💐
You can use 3% impedance choke. Any local manufacturer you can prefer. Choke is a very basic thing. Jyou have to take care about inductance, Current rating and insulation class.
Thank you Sir, Your videos always helpful... Ek doubt tha.. APFC panel me after contactor line choke laga hai 7 %, 50 kvar., Please explain why we are using choke before capacitors...?
Because capacitor behave like a short circuit when they are discharged,and when we apply voltage they draw high starting current,to limit this current we use Choke,to smooth the current during charging and discharging this choke is used.
use can use output choke in any drive for input choke you have to see user manual,if there is already inbuilt choke then no need to use external input choke
@A For Automation dear sir we are using reactor at input side of DC drive.but I am facing a problem that some time our input breaker is tripped and not found any fault code on DC drive. Please help me
Please check insulation level/moisture inside Drive and check that earthing is proper,also check megger value of Motor windings,fan condition of drive(internal), replace motor if problem gets repeat,if problem persists replace DC drive.
Sir iam not able to run an inverter ac on a 5kva sine wave inverter. Inverter transformer is vibrating even at 900 watts and the PF was at 83. I had tested resistive load of more than 2000 watts on this inverter. is there anything to do with harmonics, since its an inverter ac which has vfd like thing? also kindly provide the solution. Thanks..
The invertor output is not pure sinosoidal its PWM output which may be the problem,you can use an isolation transformer between inverter and AC which will smoothen the output of inverter.
actually its a pure sine wave inverter. i had seen similar problems with branded sine wave inverter. ok. can i know what will be the pricing for 3kva isolation transformer?
Bhut badhiya sir
Good Sujetion 👍
What an explanation excellent
Excellent explained sir hat's off to you .😊
thanks sir..we wait for your videos
Sir better better and better explain, its very very helpful for me. Thank you so much Sir
मेरा सिंगल फेज INVT ड्राईव्ह है V FD से मोटार नदी मे अंतर 100 मीटर लंबा है पंधरा HP मोटर है कोनासा चोक लगाये कृपया बताये ?
I will recommend 0.6mH, 30A Ins class-H, 3% reactor.
I have uploaded a picture for the formula
Good 👍
Thik he na...
Very informative..
Imp topic
Informative👍
Thank you Vijay😊
Wow wow n wow

Thank you Sir! Best Video.
Superb
Sir please tell me that which motor I select vector control mode and which motor I select scalar control mode pls reply to me
Thanks for
All videos are very informative.
Request you to please upload a video on "DBR"
Thanks for your kind feedback.i will make a video on DBR selection and working.
and how to design a DBR
dear sir our plant maximum drive motor....drive input use line filter and drive output use choke filter( some motor use only output choke)....when we use line filter and haw its work ???? plz details explain....see from bangladesh....
why an vfd inverter IGBT when you test a motor no damage the IGBT ?they use an adapter or power booster？
VL - L kya hai ?
440-400? Pls explain
We are welding transformer manufacturers since 1982
Very informative video

@@aforautomation what would be the price of choke ? For 7.5hp (5.5kw) motor use for lift/elevator application
Pls suggest the formula to find L (inductance)
Singal phase servo drive ke liye konsa choke lagaye

You’re welcome 😊
It's can used with SSD DRIVE PARKER?
use can use output choke in any drive for input choke you have to see user manual,if there is already inbuilt choke then no need to use external input choke
Sir please choke ko continuty say check kar sakta ha kayy
Tu homs main reading kay aati haa

is your AC running upto max power with Normal supply (Electricity Board)
@@aforautomationno..
@@aforautomation yes, but we can also adjust by using power saving mode.
Hello sir kese h aap. Sir l&t vfd programming par video bnaye. Thanks
Hello brother i am good.hope.you are also good. I will make in future.which model you are using currently?
Thanks
Sir next video kab aayega
Bahut jald..
@@aforautomation sir waiting for that eagerly
how can we design a choke is there any book or may i have your no.
Chock chalu he ya kharab he kese pata chalega your chock ko check karne ke liye Konsa meter use hota he
you can check inductance by using LCR meter.. disconnect one end of choke before checking
