DCM 12 Commutation

[@mohdfahad9384]

Thanks for such an amazing explanation, sir, it wasn't like any other explanation I come across.

Very good lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏

Sir brushes are made up of graphite or carbon...and the insulation between commutator segments is mica ..am i right?

[@a_10_bhutariteshmanish48]

sir if we use compensating winding or interpole the brush can be kept at GNA and sparking will avoid.
Then why is brush shifted and then interpoles or winding is added

[@akulagirishsaikrishna597]

underrated

[@rittikbiswas]

how much voltage induced in per coil in commutation process with diagram

[@a_10_bhutariteshmanish48]

If interpole is used then brush is kept At GNA or shifted

[@a_10_bhutariteshmanish48]

Why brush is shifted if interpoles and compenstagin wdg is used

[@kollipararajkumar7897]

Sir in cross-magnetisation actually MNA is shifted i.e. conductors under GNA and conductors between GNA and new MNA are shown in cross in this video which is responsible for demagnitisation as per cross notation,but you shown dot in armature reaction video.As per phasor i understand there is no demagnitising component but MAGNETIC NEUTRALITY(MNA) is shifted please explain it.
Thank you

Sir in shunt motor,what happens if armature is wounded with thicker wire.Can you please explain?
Thank you.

@@lecturesinelectricaleng sir I mean to say if we are wounding thicker wire on the armature what happens to commutation process

Please suggest me best Book sir...

[@anandp6876]

Good morning sir,
In commutation improvement, you said that compensation winding is also used. For better commutation only interpoles are enough as it makes the flux to zero around GNA axis. So why do we use compensating winding for better commutation?? Please explain sir

[@anandp6876]

Thank you sir

[@rnavchandan5981]

Is there any different b/w reactance voltage( inductive kick) and self induced voltage?

[@AaronLAB]

Noo both are same

[@electricalinterested8956]

Sir, how the reluctance voltage is reduced through interpoles?

Sir your lecture are really helpful!!!!
Can you please explain about equalizer rings and it's connection in windings

[@hardikgadhvi3105]

Not Mica high resistance carbon for brush

[@athulak166]

Conductors staying around GNA is responsible for demagnetization right...?
So the reason for voltage not becoming zero is cross magnetization or demagnetization..?

[@AaronLAB]

Hates off u sir.
