SM05 EMF Equation of Alternator

[@gustavomarcelo7250]

Hi. In SM04, e = 4.44f*phi*TKpKd, in SM05,e = Emaxsin(wt). Are the EMF,e in SM04 and SM05 the same?

Sir. At 6:52, why does the upper dot armature winding field axis is to the right,same with d- axis? Same with when the d axis move upwards ,90 degree,armature axis still remain to the right. Applying the right hand thumb rule, the flux will encircle the dot, and hence the axis should be the axis of the flux rotation which is out from the dot/ out from the page? In this lecture,you already decided the upper armature winding is dot, but in the next lecture SM06,you use Fleming RHR to determine the upper armature winding whether the EMF is dot or cross. So what are the info that you want to inform the student in this lecture when you decided the upper winding as dot?

Thank you sir for your service.

Very good. Thanks 🙏🙏🙏🙏🙏

Hi Sir, At 8:02, you have mentioned that when ɵ=90, flux linkage is '0'. I understand that the 'flux linkage' you have mentioned is the stator flux linking the rotor. At 10:36, You have mentioned Flux Linkages =Ø Cos (wt) Is this flux linkage represent stator flux linking the rotor. If then why stator flux is not considered in the equation.

Sir. Why does the derivation of EMF for alternator consider the armature is carrying current in your video where else other video that I watched derived the equation when the armature did not carry any current,and apply Fleming RHR ( which is the next video of your lecture)?

Hello Sir at 11:12 how omega w exist in the equation.

[@sandeep_maloth]

differentiate cos(wt) w.r.to t = -w*sinwt

[@gustavomarcelo7250]

Sir. The concept of flux linkages is only applicable when the stator is carrying current or the machine is on load, right?

Hi sir, the omega you have taken is it in electrical or in mechanical?

Nice lecture.

sir i have a doubt what is the difference between fux linkages and flux linking with the conductor

Is flux linkage concept equally valid to DC machines also

[@northkoreasupremeleaderoff721]

will u start control system also because thats the scoring subject for gate? and this lecture was awsome sir ty sir

Ty sir. It's good to know that u r from telugu states. U r really inspiring us sir. Ty sir

Why put phi is there sir

[@bangaruraj5841]

Sir what will happen in emf equation if we keep N i.e e=-N d si/dt

[@spiritualbeing4303]

Sir why haven't you considered Armature Flux linkage while calculating EMF induced?

[@gustavomarcelo7250]

Other videos that I watched did not consider the armature to be carrying any current to derive the EMF equation. I am also a bit confuse. Refer this kzbin.info/www/bejne/Y3bUpKCdqKalhZo

Armature flux is present only when current flows through armature and it happens only if the load is connected​@@gustavomarcelo7250

Hi Sir, Can you please explain, how to convert to e=-N ϕm cos⁡ωt ==≫ N ϕm ω sin⁡ωt ?
