Induction Motor #2 - Induced Torque in Induction Motor

[@mtvpayyanur]

@15:00, You said the synchronous motor with damper winding(without rotor excitation) starting principle is same with Induction motor starting principles, right? So in that synchronous motor starting procedure video you explained, at time t=0, a CCW torque will produce, and at time t=3/20ms, CCW torque is produced right? So that means in one complete cycle, 2 values of tourque induces and both will be in CCW direction and then rotor starts to rotate. So in induction motor also, in one complete electrical cycle, only 2 times(t=0, t=3/20ms) torques are producing? So comparing same rating of syn motor(with damper winding and with field excitation) and induction motors, torque will be less in induction motors right? Can u please clear my doubt Varun

[@alifkhandakar9818]

love you bro ,.,,,,great Explanation

[@kramerdortmund9282]

What's the difference between wound rotor and synch motor ? can we make the wound rotor a synch motor by using dc source on the filed

[@sochoaursamjho75]

Sir plz make some lectures on control system engineering...

[@vijeshvisal]

good explanation

Thank you sir

Thx for a Great Lecture!!

[@dvoorganisation459]

Commendable Job!

[@joymamun4459]

Thanks a lot Sir❤❤

[@upward_onward]

What should be done if one wants to incearse the HP/Kw of the motor ?....should we put larger Stator and larger Rotor ? Thank for driving away my ignorance.

[@shivaswapna1975]

sir r u from kerala !

[@-Ldvprasad]

sir please do videos on switch reluctanced motor

[@mustafayousif2696]

thanks

[@veenajindal6560]

Will this course be helpful in gate preparation

[@ShivaKumar-xq8yk]

What happens sir in motor direction and stator flux direction. When stator 3 phase winding short circuited and rotor is supplied by 3-phase supply?

[@ElectricalisEasy]

There is a detailed video in the channel...go through the playlist...

[@yaswanthkosuru]

This results in split phase inductor

[@electroboom3619]

Sir does Lorentz force does oppose it

[@SubhaEE]

Sir......superb sir

[@girishchitte9195]

Good job sir......

[@soumyasishbasu1320]

Thank you so much sir

[@TheDiverseExplorer]

Sir for torque you did Wr*Ws but in cross product direction of torque should be out of the plane...but u did it in ACW direction

[@TheDiverseExplorer]

Sir Plz solve my doubt

[@SubhaEE]

Sir please....induction harmonic torques. Synchronous harmonic torques...or crawlling......cogging.....transient states responces

[@kramerdortmund9282]

thank you

[@tanb319]

Thank you so much sir!

[@abigt282]

@02:10 how have you drawn direction of RMF.... I mean for conductor A force is coming from left to right... but what about conductor A', I mean for this conductor what is the direction of rmf... it is not clear... it is not clear for me from the video... please reply..

[@ElectricalisEasy]

The field direction would be same, just the current direction reverses...so the force direction will reverse...giving a unidirectional torque overall

[@abigt282]

@@ElectricalisEasy.... field direction will same means radially outward??

[@ElectricalisEasy]

Field direction upwards in the paper...And current direction into the paper...

[@abigt282]

@@ElectricalisEasy... then angle between current and flux will be 180 and hence lorentz force will be equal to zero..

[@abigt282]

@Varun D Nair ... then angle between current and flux will be 180 and hence lorentz force will be equal to zero...... please clear the doubt...

[@afaq5021]

sir why we take the relative speed in equ E = (V*B).L ???

[@ElectricalisEasy]

The relative speed between the magnetic field and the conductors determines the rate of flux cutting happening which is produces the emf

Induction machine kab suru kiye ...???

[@HamzaTimawi]

can you tell me what is the name of music in the beginning??

[@abigt282]

Good 👍👍

[@andrewvictor1489]

Does the speed of rotor equal the speed of flux of rotor ?

[@ganjiabhiram8810]

I did not understand how rotor current will be in that angel. Bro plz help. Me

[@kabirkhan-qb9hn]

sir in case of transformer why no torque produce but their still induction process present..please solve this problem in next doubt lecture.

[@ElectricalisEasy]

This is a good doubt I will put it up in the next weekly doubt clearing session...

[@yogeshgupta4577]

Torque is concern with rotation and in transformer, there is no rotating element.

[@afaq5021]

sir can u explain the meaning of space variation of flux ???

[@ElectricalisEasy]

Space variation means the distribution of the value of flux with respect to different points in space

[@anjalishreya8210]

sir why u taking "i" in this direction with respective to "B" 1st flux cut the conductors ----emf induced----current flow----conductors of rotor experience a force

[@anjalishreya8210]

how can i find direction of current is by using right hand rule?

[@ElectricalisEasy]

It is direction of current in space...

[@lipikanaskar5369]

Force is proportional to L×B ??? Why I×B is taken here?

[@mohitsingharia485]

sir can your share the notes of all your lectures of induction machine on whatsapp..?

[@ElectricalisEasy]

Mohit singharia I don’t share in WhatsApp, my notes are uploaded in a Wordpress page, but for induction motor I have not completed compiling the document because due to lockdown I want to complete the course first...and in the meantime do try to prepare your own notes while watching the course, that’s the best notes ....
