What is VFD?| why VFD is used in Train| Why is VFD used in AC motor in train engine? |Working of VFD

[@nairaahmed1327]

Bhai aap bahut acha explains karte ho

[@fried-_-potatoes-l]

Sir power electronics pr bhi thoda bahut vdo dal dijiye

[@akashsingha4985]

I am from west bengal .the video is very knowledgeable. Thanks

[@NOMORErattamaar]

I am also from west bengal, Keep learning :)

[@kkkrishnan4611]

Very very good sir

[@MDFAISAL-id6oj]

Mast hai Bhai 👍👌

[@NOMORErattamaar]

Thanks bhai ☺❤

[@sushilchoudhary5749]

Good informative video.

[@ambujkumar1005]

Please make video difference between EMU and metro train

[@yogesh9818]

Very valuable knowledge sirji thanku

[@NOMORErattamaar]

😊😊❤❤

Tysm sir ❤️

[@rajnishkumarrajan4379]

Luv u sir thank you so much

[@mirchalesunofficial9910]

Really useful

[@pradhumnsingh7005]

Give a lot more information on this video about train to traction motor but please MAKE one more video about VFD it controlled frequency and voltage

[@prashantmittal9329]

Awesome brother

[@praveenkumar-uu6ht]

Pls sir make more video about vfd

[@kumarnerella2122]

Diesel locomotives generator capacity kva??

[@abhisekhrai6706]

3phase induction motor... HZ 50 voltage 440 ... vfd se hum frequency matlab 60 hz ko badate hain ghatate hain... yeh dowt clear kariye ...

[@bashistpatara873]

👍👍👍👍👍

[@debiprasadpradhan5118]

VFD VS VVFD Me ek video banao sir

[@NOMORErattamaar]

Debiprasad ji ye VFD, VVFD, adjustable frequency drive (AFD) sab same hai.

[@prashantmittal9329]

Bhai star delta ke baare me btao

[@NOMORErattamaar]

Okay :)

[@ravindandge2540]

Notching Relay se train ki speed control hoti है, plz share detail about that

[@railpilotanand5123]

BL box ke shwch ke working batao

[@shahidqadri4340]

Kindly let me know about voltage the of step down transformer which is using for traction motors as wel as

[@19041990pramod]

Let me answer this question. Normally voltage is stepped down from 25KV to 1KV because in general rated voltage of Traction motor is about 1000V

[@anjalithakur8253]

Sir plz explain kro details m capacitor kse power factor improve krte

[@NOMORErattamaar]

Noted! Bahut jald aayega :)

[@souvikdey3918]

Vfd mein vector or scalar kaise pata karen?

[@krahulbhat5065]

bhai. hum voltage aur frequency dono sath me change karne badleme hum sirf voltage ko change karke to bhi speed vary hotai hena.. too train me dono kyu vary kar rahehe?? please bataoo bhai

[@NOMORErattamaar]

Nhi aisa hum nhi karte sare motor ka nature alag alag hota hai, is main hum 3 phase squirrel cage induction motor use karte hai jika speed ko sirf "voltage" ko change nhi kijya jata hai agar voltage kam kare toh iske core ki flux density kam hojata hai hum hamesa flux density ko constant Rakhne ki koshish Karte Hain takhi system jada se jada efficient ho hum jitna power derahe usko ache se utilize kar paye. E=4.44* f *(phi)* N Is equation ko dekho sare constant ko hata de toh aur thora rearrange kare toh E/f is directly proportional to (phi) This "phi" is flux density. Toh yahn se ye samjh main aata hai agar E(voltage) kam kare toh flux density kam hoga agar f kam kare toh (phi) jada hoga. Ye sab samjh nhi aaya toh bas itna samjh lo ki sirf voltage Ya frequency ko control kar hum speed control nhi karke train main.. Kam efficient hota. Isliye ye jo V/f ka ratio hai usko constant rakhte hai matlb jitna voltage badaye ge utna frequency bhi jitna voltage kam kare ge utna frequency bhi isko he V/f method of speed control bolte hain. Is VFD se speed toh control Karte he hain uske sath sath torque bhi bahut ache se control kiya jasakta hai motor ki starting torque badhaya ya ghataya jasakta hai jo ki kisi bhi traction motor ke liye bahut important hota hai. That's why we use VFD....not any another method of speed control.
