Thank u so much sir for ur quick response I get all the concepts very easily and finish my syllabus that's a beauty of a legend teacher. Thank u so much, sir.

Sir if rotor rotates less than synchronous speed then there will be some relative speed among stator and rotor MMF then they will meet after some instance and torques became zero??

Sir in this lecture at 27.15 in case of squirrel cage rotor u r saying that both MMF is in the same phase but we all know that stator MMF is leading from 90 as we saw in the above diagram there relative speed must be zero but they have a phase difference of 90 which explanation is true?

Sir, why magnetic locking not haporns in cage motor. As rotor ooles are created according to stator poles so it should get locked.

Sir at a stand still condition we assuming that flux produces by there respective MMFs or fluxes but at running condition, both produce due to resultant flux is it true?

Sir am not clear (02:58) with respect to stationary flux conductor is moving in counterclockwise direction .... Here , I got confusion in direction
@AshishKumar-jx8ng3 жыл бұрын
Please see with respect to rotating magnetic field Then the rotation of conductor will be counter clockwise direction whether the magnetic field rotating in clockwise direction

Sir, if we give 3 phase supply to both stator and rotor then will rotor be rotating??????

Sir please explained if rotor makes to rotate opposite to stator RMF. Then what happens to parameters like explained in vidoe.

sir! Can you make a viedo on how a induction motor takes about 6 times current in starting. what are all the parameters that makes starting current upto 6 times.

Sir when u explain the Fleming's right hand rule Conductor comes under North pole induce current goes outwards.bt here conditions same but current come into it.why

@@lecturesinelectricaleng E1 and E2 are in phase, means no phase shift. But in primary current enters tge dot and in secondary current leaves the dot, then we can say it is doing 180 degree phase shift.
