Excellent lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

Very interesting lectures. Thanks you sir.

Hi I think stator is constructed from hot rolled steel as cold rolled steel is anisotropic which is suitable more in Transformer

Sir at 18:32... How the armature reaction reactance decreases increasing of air gap length.. Sir could plz explain...

[@randhircheema1642]

Thank you for prompt reply to my previous doubt. Question: At 04:12, in the figure, even though the direction of current is 'dot' for all four conductors, but the flux direction shown by you is downward!. Would it not be towards the right hand side as per FLH rule? Regards.

[@lokesh6229]

sir, you explained in open type slot magnetizing current requirement is high and leakage reactance is less. but in synchronous generator magnetizing current is supplied by dc so that is already with constant magnitude. little confused sir!

[@surugayatri2062]

Practically wedges are placed on armature slots ..so that winding doesn't come out. Do wedge also offers same permeability to flux path sir??

[@deepankarmajumder2404]

Sir, For open type slots, the voltage drop is less because the leakage reactance(Xl) is less (as the leakage reactance is in series). But in Power System, we learnt, reactive power at receiving end(Qr) is inversely proportional to synchronous reactance (Xs). Now, if leakage reactance(Xl) is less, then synchronous reactance(Xs) is less, then Qr is high. We know, major cause of voltage drop is reactive power. So, as Qr is high, voltage drop will be high. So, the above two conclusions are contradictory

Sir in open slot air gap is more than why leakage flux is less

Sir mention all point to cover each amd every topic its very useful for us.

Sir I preparing for competitive exam for electrical engineering would u help me for the exams

Useful flux kadha sir low ; leakage flux is high sir is this right or wrong ?? Sir

[@sabavathrajkumar323]

Open slot more commonly used in stator synchronous machines why? Sir.
