Sir why in single phase induction motor the net flux does not increase as like in transformer to maintain flux constant the primary current increases which increase the primary flux .
3:08 u said rotor mmf will be opposite as to oppose the cause but there will be rotor impedance angle lag in the rotor mmf which will cause it not to be 180 out of phase with stator mmf and consequently there will be torque. Right?
sir, why are we applying flaming's right-hand rule for a motor? are we not supposed to use the flaming's left-hand rule for a motor, and the flaming's right-hand rule for generators?
Sir. As you demonstrated, if rotor is standstill, induced emf will be such that its flux would be 180 out of phase to give zero torque. But if I hand rotate the rotor with OMEGA=OMEGA of 1-Ph supply, the induced emf will be zero, right? + At 7.42 in the video, why you are showing 'Phi S' and 'Phi R' in same phase?
For the domestic fans we aren't giving any pushing force to the rotor, then how they're are starting sir please.. In the explanation you are saying some pushing force is required.
Sir induction machine is like short circuit scandry transformer in which stater flux and the rotor flux are 180 degree out of phase according to Lenz law (( otherwise it will not take any current from supply under load condition ))... .But in this case stater flux and rotor flux are in phase with each other ....How. Sir it is possible
Extraordinary..Thank you very much! It's really helpful to me.
Thank you for your awesome and vivid explanation...
Awesome explanation sir!
Extraordinary explanation sir ❤️

What are indicates of fingers in right hand thumb rule?
sir flemings left hand rule is used na sir as it is a torque production
3:08 u said rotor mmf will be opposite as to oppose the cause but there will be rotor impedance angle lag in the rotor mmf which will cause it not to be 180 out of phase with stator mmf and consequently there will be torque. Right?
5:42 , forefinger is pointing to right to left , but you're saying left to right
Sir right thumb rule is reverse of what you told know??
Very good. Thanks 🙏🙏🙏🙏🙏🙏

I didn't understand that right thumb rule concept what u said?
Thank you sir.
Is cross field and armature reaction theory are same
Sir, normally current entering from the air to body we take as cross but here you take as reversed?
For the domestic fans we aren't giving any pushing force to the rotor, then how they're are starting sir please..

Thank you sir very Helpful 🙏🙏🙏🙏🙏🙏🙏
Thank u sir very explanation.

Rotor flux is opposite phase to stator flux but you are represented in same phase why sir
Sir in frist diagram current direction, dot different, that is not correct
According to cross field theory single phase induction motor can selfstar or not.
Thanks for your reply sir.
Then how the single phase induction motor will selt start
By intial rotation it produce motional emf
Super sir
Sir why you multiply fluxes w. R..t wt only why not teta
Sir i didnot understand about taking wt and teta reference
8.50 sir
@@proddaturureddy2422 wt is with respect to time i.e transformer induced emf and wrt to theta means space , distribution of flux in space.
Nyc sir 👍👍👍🤘🤘
❤️❤️❤️
Taark 😸
