Thank you very much sir for providing us precious knowledge free💯❣️ Sir, make more videos on all concepts.

[@Burhannazir456]

All concepts got clear.... awesome lectures

[@mscourseiit-k7538]

Just for rememberance - the low freq. sine envelope is of freq corresponding to Ns-Nr. while HF sine frequency is of frequency 50Hz or supply frequency.

thanks Sir🙏❤

Sir.... rotor is open circuited know? Then what is the significance of applying less than rated voltage. What happens if rated voltage is applied ?

[@Nani444Nani]

Rotor is open circuited so there is no back emf thats y we r applying less voltage that is 20 to 25 % of Rated voltage to stator... I hope this is clear to u

[@Veer-ss6et]

Awesome lectures sir

[@Burhannazir456]

Thanks very very much

Sir why Isc lags Ef by 90° during short circuit

[@Nani444Nani]

Actually EMF is directly proportional to Flux ... So whenever flux is maximum then induced emf is also maximum @ D axis... Why EMF is zero at Max flux

[@souravsen2981]

See emf from faradays law is directly proportional to the change of flux not the flux, so from this analogy if you take phi = BA cos(wt) then if you differentiate it to obtain the emf the cos(wt) gets converted to sin(wt) now at d axis the wt i.e the angle between the B vector and A vector is zero. So the wt=0 so sin(wt)=0, so the emf becomes zero when the SMF aligns itself along the d axis. Hope you are clear

Sir give lectures in English

[@nominkhokhar6502]

Hum you tube regional language me padhne ke liye use karte hai ja tu college me dhyan se padh waha English me hi sikhate hai

[@College19]

Mai video ko dislike karta hu...kyu ki sir ka aise back & forth video me jyada ghumne se mai irritate ho jata hu...
