Bro we can also change sine wave to desired frequency ..by using cycloconverter as cycloconverter is AC to AC converter at different output frequency....now so why we can't use cycloconverter instead of rectifier and inverter in a drive ?
Bro we convert in dc only because we have to change the frequency and for changing the frequency we require inverter and inverter requires dc input that's why we change ac to dc first then if feed to inverter and by varing firing angle we change output voltage and frequency to control speed
Kranthi, for power consumption one need to do analysis of running load and the requirements of plant. There are not much things to say without doing analysis of System.
Some application, need to reduce speed motor more faster than natural mechanic inertia, during reducing motor action like generator convert mechanic energy back to the heat at braking resistor
Good explanation.. Does V/f also remains constant in vector controlled VFD ? i.e. if a motor which is rated as 460V/60Hz is made to run at 30 Hz, does the voltage still remain 460V ?
Sir , while stopping IM , we know three breaking methods and as I have a doubt in some applications we use DBR and in some we don't ? and breaking methods changes as per application in drives ?
Why the motor not get burn in case of VFD as frequency is zero at starting? Induction motor is acts as a transformer and if frequency is zero at starting.
Can you please make a video explaining the parameters of a circuit breaker(breaking and making capacity, max fault kA rating) for a ABB or Schneider breaker and how it is calculated.
Hi Abhishek thanks ...apke vajah se Electrical related concepts jaldi clear hota h...👌🙏
Thank you so much Akshay for appreciation..🙏
Also watch playlist for videos related to Drawing, Calculation, Motor, Transformer, Power Factor Correction and many more..
Moral of video, Depth technical 30% lengthy explanation 70%💐
@aviray5877 I'm agree with you
This is called perfect explanation great sir. My main dout is why we convert ac to dc and now my dout is clear thank u sir.
Beautifully explained 🇮🇳✌🏻
Ap badhiya samjate hi sir ji
Thanks sir interview question ka lea
Most welcome Rishikesh.
Very informative...🙏🙏🙏
Thank you..
The way you explain things is just brilliant.
Can u make more question on vfd plz for interview.
बहुत ही अच्छा सर ।
Good information
Superb , point to point answer 🔥🔥🔥🔥
Very nice explanation.
Please explain differences between vfds and softstarters. Also explain reasons for selections of vfds and softstarters.
Very nice explanation
If you process need to vary speed of motor, use VFD.
Great my important dout is clear thank u so much.
Superb senior 👌
Thank you Gaurav...
Well explained..
Thank you..
Excellent and keep it up bro
Sir aapne bilkul sahi kaha per me bol Raha hu ki vfd se kitne kw ki motor run kir sakte he
Impressive video.
Excellent explanation sir 👍
Good work bro vfd pr ek full explain with conection video banao
Okay Ali..
Wao...nice explain ,thank u sir
Jo aapne bataya why we change to dc
Wah Maja aa Gaya
Beautiful explanation.
Great video sir
❤..very well explsined
Thanks bro, very good explanation
Please add some more questions about VVFD
Superb bro
very good
Very nice explain
Good
Nice explanation😊
Nice videos
Excellent
Well done sir
Nicely explained.. Thanks 👍😊
Sir please V/f in inverter ? Explain
amazing explanation
You’re video is very helpful
Thank you Nikola.
@@electricalwithabhishekjoshi sir what is difference between sensitive earth fault and earth fault
Great sir... make video on PLC automation also
Thanks sir mai elevator lain mai hu
Thanks for useful and knowgable video sharing.
Thanks so much for valuable information
Thanks sir very helpful
Sir vfd ka use karke ham motor ki rated rpm se jyada rpm badha sakte hai kya
good and excelllent video but sir vfd industrial use is multiple vfds what reasons
very nice...
Due to high harmonics in our plant VFD and Motor got damage can you suggest any equipment to reduce the harmonic
Nice bro 👌
Bro we can also change sine wave to desired frequency ..by using cycloconverter as cycloconverter is AC to AC converter at different output frequency....now so why we can't use cycloconverter instead of rectifier and inverter in a drive ?
Why motor produces humming sound while using VFD
And
If possible please explain about
Internal parts of a VFD like dc choke and filter etc etc
Okay Saikumar..
Single phasing hua hoga
High switching frequency trig IGBT is the cause of sound
Good explanation
Kya VFD ko electric bike me controller ki jagah pe use kar sakte Hai?
THANKS! Very Good lecture! 🙏
Vfd check kaise karenge usske upar ek video banaiye please..
Thank you Sir
VVVFD ka upar complete video banaye sir please
Sir please explain about IGBT and test
Kya VFD ka input supply change kare to motor ka direction change hoga
Bro we convert in dc only because we have to change the frequency and for changing the frequency we require inverter and inverter requires dc input that's why we change ac to dc first then if feed to inverter and by varing firing angle we change output voltage and frequency to control speed
The topology circuit that use mostly nowadays is voltage source that convert AC to DC capacitors then use inverter firing PWM patterns to vary u/f
Please explain more briefly regarding why we have to convert ac to dc other than waveform
There are many power electronics topology for VFD, Voltage source apply ac to dc store to dc capacitors then inverter to motor
Bro, please make a video on power saving in industries .
Kranthi, for power consumption one need to do analysis of running load and the requirements of plant. There are not much things to say without doing analysis of System.
please make a video on "why braking resistor is used in vfd?"
Some application, need to reduce speed motor more faster than natural mechanic inertia, during reducing motor action like generator convert mechanic energy back to the heat at braking resistor
Sir, make a video on REACTOR.
Good explanation..
Does V/f also remains constant in vector controlled VFD ?
i.e. if a motor which is rated as 460V/60Hz is made to run at 30 Hz, does the voltage still remain 460V ?
No, otherwise the motor will have saturated magnetic flux
V/f mode me running 30hz par 460 v vfd nahi degi
Output par 250-260 ke vich voltage milenge
Sir , while stopping IM , we know three breaking methods and as I have a doubt in some applications we use DBR and in some we don't ? and breaking methods changes as per application in drives ?
kon si waveform ko modify karte hai current,voltage,frequency
Thank you sir
Sir ji Motor , Generator & Transformer ke Name plate ke upar video banaiye na please 🙏🙏🙏🙏🙏🙏🙏
Metal detector ka video banaye
Tq 🙏sir
Sir what is difference between u/f and vvc Motor Control principle ..please make video on this
U/f only control and keep ratio u/f, vvc have to control flux component and torque component separately
Bhai kia Vfd invetar lagany sy ham ect bill kame kar sakty h.yane bajle ke saving ho sakte h plz
Thank you alot Sir
Sir , soft starrer & vfd ki comparison per video bneye
Okay Arpit..
❤❤❤❤
Sir imcc pe video banaye
Sir VFD and Variable Frequency control of an induction motor drive , Both are same na ??
Thank you sir🙏
AC drive ke I/p per single phase supply dene pr Kitna DC Bus voltage banta hai?
85
40 watt gear motor 60 rpm with brake
Aisi motor ko VFD lagaya ja sakta hai ?
Ek vfd drive se two motor ke liye kon se parameter important hai
Summing of two motor current
You explained why VFD , where VFD but you forgot to explain How actually VFD works ?
Vfd rpm ke sath torque ko bhi control karti aur torque ko control karna hi vfd ka Maine work hai
Why the motor not get burn in case of VFD as frequency is zero at starting? Induction motor is acts as a transformer and if frequency is zero at starting.
Sher vfd per motor car driving sad wala bearing garm Kyon Hota Hai
Sir kia hum rpm 1500 say ziada bhe kar sakta han ? Thanks
Sarfraz, hum motor ka RPM, rated RPM se jyada nahi kar sakte.
@@electricalwithabhishekjoshi Thank you sir, from PK
Most welcome Sarfraz.
Yes karsakte h lekin motor na generator ki taraha Kam krne pages with negative slip
Nahi
