No the disadvantage of variable resistor method is that when resistance increases current decreases. The starting torque also decreases. Heat generation is not a problem because Heat=I^2 * R. R may increase but I also decreases. I having square and R having power 1, the effect of R is less than I.
your DOL starter circuit is not okay.. that contact connected to OLC coil should be normally close.. when over current passes that olc gets highly magnetized as a result it attracts the contacts and break the circuit as a result machine stops.. you just need to make OLC contact Normally close and make it to right right of the connection..
Nitin Patel " No, because STAR connection ka use hamlog starting me karte starting current ko provide karane ke liye aur jaise hi motor apne full rated speed ke 80% ho jata h to motor ko DELTA connection dete h. Motor ko ham log DELTA connection me hi chalte h na ki STAR me.
Electrical Engineering Idea's mere paas 2 motor hai 1) 10hp 960rpm jo star or delta dono mein 5 ampere par chalti hai aur 2nd motor 20hp 720rpm ki hai jo star mein 5 ampere aur delta mein 19 ampere pe without load chalti hai, iska kya karan ho sakta hai?
Nitin Patel " current ka jo consumption hota na wo pahle se hi specified hota manufacturing ke time, ki kitna current no load pe use hoga aur kitna current full lode pe use hoga. Thas why"
JAGADISH PATEL " Aap conductor ka size bol rahe hona??? Current ke value ke upar hamlog conductor ke size ko select karte h, ki kitne ammount me flow hoga.... And everywhere ham current ke value ke upar hi conductor ke size ko select karte h."
JAGADISH PATEL " ham log conductor ke size ko calculate karenge... Ye aik process h sb se pahle ham log starting current aur running current ko find karte fir uske bad current density assume karte aur fir current density ke formule se cross sectional area nikalte h aur jab cross sectional nikal jata h to SWG ke help se hamlog motor ke conductor ke size ko calculate kar lete h....."
Lv u bhai❤❤
Finally found which i needed most..book mein se padke kuch bhi samaj nhi aa raha tha..thank u so much again...
great concept diye apne...oo vhi kafi kam time me.....thank you so much....

Very helpful,,,, I'm new subscriber.
I'm new commentator
Explanation was good 👍
Very nice and easy to understand
as u said the DOL is used for motor below 5 kW . so what is the rating for stator resistance method
Very nice 👌👌👌
Sir squirrel cage motor on load pe kyu nahi Start hota????
20hp 750rpm star delta motor ko sirf star mein chala sakte hai?
Nitin Patel " No, because STAR connection ka use hamlog starting me karte starting current ko provide karane ke liye aur jaise hi motor apne full rated speed ke 80% ho jata h to motor ko DELTA connection dete h. Motor ko ham log DELTA connection me hi chalte h na ki STAR me.

Nitin Patel " 20hp motor ke rating plate pe no load current kitna likha h???"
Electrical Engineering Idea's aisa kuch nhi likha hai, but full load amp 31 likha hai, GEC company ki motor hai
Nitin Patel " current ka jo consumption hota na wo pahle se hi specified hota manufacturing ke time, ki kitna current no load pe use hoga aur kitna current full lode pe use hoga. Thas why"
The type of starter is used to start slip ring induction motor?
Rotor resistance starter
Bahut achha hai ji
Nice sir it is very helpful for me
5hp induction motor के लिए कौन सा स्टार्टर लगाए और किस कम्पनी का
Mahesh bhargav "DOL method ka use karte h"
great sir❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Better sir nice🙋
It was very helpful
Best vedio bhaii👌👌
Can you give expression of torque for each cases?
Thanks sir❤❤😊
Stator resistance strater ise for slip ring or squerrial cage induction motor ??
Best explanation
Good❤😊
Pls Put the link of next video in discription

sir relay and contactor dono rahan ga to .
Thanks sir, Jones chopper par bhi ek video bnaiye details me
new video chahiye singel phase motor ka.....plessir
Hello sir yesa channel mujhe bhi bana hai kese banau
Raju rastogi present😂
SIR AUTO TRANSFOMER STARTER ME CONTECTOR SIZE KAISE SELECTION KARTE HAI.
JAGADISH PATEL " Aap conductor ka size bol rahe hona???
Current ke value ke upar hamlog conductor ke size ko select karte h, ki kitne ammount me flow hoga.... And everywhere ham current ke value ke upar hi conductor ke size ko select karte h."
Soch lije 30hp ka motor Hai to main contector ki size kya hogi???
Run ki size kya hogi or
Star ki kya hogi.????
JAGADISH PATEL " ham log conductor ke size ko calculate karenge... Ye aik process h sb se pahle ham log starting current aur running current ko find karte fir uske bad current density assume karte aur fir current density ke formule se cross sectional area nikalte h aur jab cross sectional nikal jata h to SWG ke help se hamlog motor ke conductor ke size ko calculate kar lete h....."
JAGADISH PATEL " Is process se hamlog conductor size nikal sakte h fir chahe wo 30 hp ho kitna v rating ho."
Sir ji me contacor ki bat Kar raha Hu. Conductor ki nahi
Good explanation
Acha h ...pr thoda English pe Dhyan dijiye...
Malawati Kumari " thankx for compliment"
sir kis h. p. per use karenge ye to bataya hi nahi
Good concept..
Plz explain in english🙏🙏
😂
5- Rotar Resistance starting
Ye bhi ek starter hota hai n
Yes, ye rotor resistance starter jo wo rotor side ki h but maine jo 5 starter bataya h wo stator side ki hai.
best video
❤️🔥❤️🔥❤️🔥❤️🔥
very nice sir
Thank You 😊
nice video
Oil emmersed कैसा होता है
or sare new video banaye sir......
very nice video
❤❤❤
Thanks sir
Nice
Can you explain in Telugu plzz sir
Thank you
Thank u sir .
bhai thoda tez pda liya kro or ek hi chij ko dus bar mat btaya kro...
sir apka qualification keya he?? ap keya teacher he???
Rj sayan " Mai aik teacher nai hu bs mera motive ye h ki mere pas jo v knowlage wo mai sab tak bat saku, sab ko sikha saku."
apka ye simple language ka consept mujke bhot help kar raha he.exam time. mhe electrical engineering par raha ho .....tnx
2nd method achi trah smjh nhi aaya 🤔
Can you PLZ explain in english
thoda better explanation dejiye
Thankyou...
sir apka whatapp number or facebook id he keya??
Rj sayan " 9827045380 is number se fb par search karo DANI ARYA ke nam se aik profile aayega wo hi h"
whatapp hoga keya?
did't match dekha raha he fb per
Rj sayan " isi number se whatsapp h"
ok thik h
Not show any formula
Istarter jaa starter 🙄
English Needs Improvment otherwise Good Effort :)
Correct answer: burr burrrrrrrburburburrrrrr
Dehati teacher jb aata ni to kyu padhaa rhaaa
Not too good
Speak some English man
