Sir one doubt...unity pf means Current is in phase with terminal voltage V ,not the induced voltage E. Please explain it sir....why in armature reaction they always consider induced voltage...
Sir by the armature reaction flux is decrease so generated emf is decrease. This is clear to me but why we consider armature reaction effect as a reactance while we can consider emf decreasing .Why we consider emf is constant
Sir..in UPF.... The angle between main field flux and armature flux is 90deg..so flux linking is zero.. Because cos(90)=0....but how the resultant flux..we get sir.. Plz clarify the dought sir..
Sir, how do we define the power factor for a mechanical load in case of a synchronous motor? Like, I can understand in case of a generator, the load will be electrical and hence we can define lagging or leading load. How we interpret the power factor in case of mechanical load?
Sir i confused that here we understand that under lagging pf synchronus motor act as over excited but when we study about power factor correction we say that synchronus motor act as over excited under leading pf
No ad, no marketing.. This is simply gold. The best our there in you tube as far as I have see.
Best teaching I ever seen...
Great explanation sir
Please Keep uploading such type of awesome videos

Thank u sir much helpful continue to do such videos
thank you very much sir

@@lecturesinelectricaleng Thank u sir.
sir what is the difference between reactance drop and resistance drop both are decreasing the terminal voltage what is the difference???
Thank you sir

Ok sir
Sir kindly so network analysis also
Sir how to calculate ampere turns sir
👏👏👏🙏🙏
