Lol
I agree. It's amazingly clear.
Thank you so much
ATTENTION: The current deflection is maximum when it comes to the horizontal position and zero when it comes to vertical.
Yes, I must change this
and so we use multiple coils
why is that?
Tq ❤️
You still haven't changed it. If your going to explain things it needs to be correct.
The reader should not be confused as a MUST keeping same direction on the armature: changing within direction is the mainly purpose of changing within polarity itself i.e. we changing polarity because we need to (2) repel after being (1) attracted. Thanks to a simple solution - commutator (splitted ring) . I found this video as a supplement of: How does an Electric Motor work? (DC Motor) by JaredOwen on RUclips. Still I want to thank the author for all efforts exerted on making of this material. Cheers :)
only 1 min in and u explained it better than my teacher.
Thanks, nice feedback
Sir/mam, I am very thankful🙏 to u for this beautiful topic, I understood very easily...i hope this type of explanation no body will provide 🙏🙏🙏
Thanks
Really nice animation. However, viewer be aware: there is a Physics error - the EMF versus Time graph should peak when the armature coil passes through the horizontal position and be zero when it is vertical
Yes, this is mistake
Note that he uses conventional current flow, if using electron current flow then the left hand rule needs to be changed to right hand and the pictured direction of current flow is opposite.
You mean right to left. Not left to right.
Can u please tell me where to use which "hand"rule 🤔💕
I searched all of the time to see this video.
T̆̈h̆̈ă̈n̆̈k̆̈ Y̆̈ŏ̈ŭ̈❤️
Thank you so much for your video.... Your voice gives me a feeling of a documentary btw 😊
Thanks
nice explanation, this video has improve my knowledge
Glad to hear that
I am student in Iraq and now I understand the lesson so thank you very much
Thanks for nice feedback
Finally I understood.
Thanks a lot 🙏😊
No problem
What a great work of art. Thanks for making this 🙌🙌
Nice to see new students.
Worlds best tuition classes is Vidya Classes and Best Teacher is Sir Shinde ❤️
OK, That is great
Question:isn’t the induced voltage highest when the armature is passing through the magnetic field lines at a 90 degree angle? And shouldn’t the Voltage be zero when the brushes are between the gaps of the commutator? This is not how the graphic demonstrated.
What part of the video
for minimizing such defect commutator can split in many parts so that gap can be reduced
You cleared my concept thank you.
Glad it helped!
Make the video about, in which position of the conductor the induced current will be maximum, whether in parallel or perpendicular to the conductor?
Thanks for idea for topics
HI IN YOUR VIDEO MAJOR MISTAKE THERE. THE EMF INDUCED IN COIL ARE NOT AS PER VIDEO PREVIEW ....YOU TOOK EXCTLY OPPOSITE OF ACTUAL PROCESS....ONCE CROSS CHECK IT. EMF INDUCED IS MAXIMUM WHEN DIRECTION OF MAGNETIC FIELD IS PERPENDICULAR TO DIRECTION OF MOTION OF CONDUCTOR......
es you are right, rhis is made opposite I will change this preatty quickly
It looks like your graph of induced emf and coil position is off. You should have a maximum induced emf when the coil is horizontal and a zero emf when the coil is vertical. Other then that it is a very nice animation and described well.
No, I think that IM right because when the coil is in the horizontal position it means that total flux that produced by stator is perpendicular on the area of the coil so the angle equal 90
, so maximum value when sin(angle)=1 , angle = 90
@@chrvoje_engineering It's the rate of change of flux which causes the emf as that it greatest when the coil is horizontal (moving from 0 flux to a rapid change of flux linkage) and minimum at maximum flux linkage. See here
electronics.stackexchange.com/questions/30053/why-voltage-lags-by-90-from-magnetic-flux
@@MrForbinator I think that this what you say that is not correct, I think that on bottom of the article somebody say that this is incorrect
When the coil is horizontal, the cutting or blocking of magnetic lines is minimum but the rate of change of fluxes is maximum which produces maximum emf.
I think that Im right but....
My PhD is in Feline-Neuropsychiatry.......but I still have a hard
time with this....thanks.
Thank you sir for the explanation .its very helpfull to my education purposes . I subscribe and like your channel.Again thank you
Thank you
Around t=6.00 , emf is max when coil is closest to pole and cutting least flux. EMF is min when coil is exactly between poles. But in the graph you have shown it otherwise.
Thanks 🙏🏾 so much it was helpful may GOD bless you ❤❤
Thanks alot and pls keep on making more videos of this nature...
Thanks, I will
Thank you sir 😊
No problem
You saved me a lot of trouble
Thanks, for nice feedback
Seriously helpful video!
sir..When does the armature in the direct current generator rotate in the Anti clockwise direction?..
the animation is right. thank u for clearing my doubt.
Really helpful thank you so much sir...and continue uploading videos more and more.....
Thanks
Hello - one question. Wouldn't the light bulb flicker with the pulses - especially if its an LED bulb? How do you maintain constant amps & volts in this design?
It does flick but due to how fast it is doesn't really show unless there's a problem in voltage take a slowmo of a led light and it will answer ur question
Thank you so much for this video ☺ it is really helping me a lot 😃 but I have one question : how can we increase the speed of rotation?? And how can we control it??
I am request to make a video on electromagnetic induction. Please 🙏

@@selfiee_queen5712 if have brain then definitely you will understand but if you don't then what I suppose to do?? 😏
@@selfiee_queen5712yaa sis , if u wanna to understand then u have to focus on English a little bit more 🥰☺️
Thank's .
This video make my chapter very easy.
Thanks
Good explanation and great animation
Thanks
Thank you so much for your valuable information🤩🤩🤩
Thanks for nice feedback
the carbon brushes are used for collecting the current from the commutator and also to change the polarity?
Yes
This video help me lot for my exams
Thanks, I'm glad
Thanks a lot ,sir❤
No problem
Mind blowing 😚..concept clearing video😊
Amazingly helpful, thank you so much.
Glad it was helpful!
A nice explanation
Thank you 🙂
Thank you you made me pass an exam
Flemings right hand rule is wrong
Thank God i found this
Thanks
Thanks , you helped me a lot
No problem Im glad
Great work sir very useful
Nice teaching
Thanks
Just wondering. If electric motors use electric energy (supplied through a battery) where do generators get mechanical energy?
Thru rotor of the motor
How to make this type of animations.. which software are you using???
I wanna know too
He's using 3D Max, it's in the description :)
I want to know where the insulating material is located for the coil and the two slotted cylinders. Thank you in advance.
Two minutes silence for those who haven't seen this video🤐
I belive that this is good feedback
Nice explanation. This video helped me lot.thank uu
Thank you soo much....I need ac generator too
Very helpful 👍 lecture thanks a lot

Thank you this is very usefull
Thanks
@@chrvoje_engineering one small doubt. How does the current direction changes if we doesn't use split ring? Please explain
@@harishm7328 How you mean It doent change
Looks like dc generator is just dc motor without the battery..
So y does the dc motor require battery if the coil can still rotate without the battery
Superb animations
THANK YOU IT WAS QUITE HELPFUL!!!
Thanks for nice feedback
You say flemmings right hand rule, but isn't that flemings left hand rule ?
Left hand rule would show the direction of magnetic field the right hand shows force which is what’s required in a generator
Sorry, for late replay, I agree with adit g, and add that my teacher allways say left hand rule is for motor, right hand rule is for generator
Fleming's left-hand rule is used for electric motors, while Fleming's right-hand rule is used for electric generators.
Thank you!
No problem
This is both a motor and a generator. When i spin a DC motor it generates electricity.
Thanks sir ❤️🌹
So nice of you
am downloading ur video for to see in offline,, thank u

Sir which software is used to make this animation
3d max
nice video
thank you!!!
Superb explaintaion
Thanks
The graph drawn in video is cos wave sir
But you told that that sin wave
I didn't understood how the current is reverses can u pls reply me
Split rings or commutator is used to reverse the direction of current
It should be Fleming's left hand rule not right hand
Right hand for generator and left hand for motor
The voltage graph at 5:34 is wrong, coil is at 0° when it is verticle( Force/ Torque direction is parallel to flux direction) and 90° when it is horizontal( Force/ Torque direction is perpendicular to flux direction), the EMF induced in the coil is maximum when it is at 90° and so is the current and vice versa. E = 4.4 N F Q sin(theta)
Yes you are right, I need to fix this but I will do in remake of this video
Thank you sir
Your animation is super
Understood. Thanks
No problem!
You didn't explain How emf is induced in coil, why maximum emf induces when coil is in horizontal position and no emf is induced when coil is in vertical position. Please explain that too. Waiting for your reply.
Coil coming from vertical to horizontal position. It cuts magnetic flux more and more. So rate of change of flux is maximum. There by max emf induced. Main thing is that flux and coil direction is at 90 degree. It should be fixed. If these two are in parallel no fluxes are being cut by coils. So no emf induced.
Thanks for sharing...
great video
Thanx this video help me a lot
No problem
How can I desrive this video
Superb
Thanks
Any body rply in generator first we give dc supply to armature to rotate magnetic field then it produces electrical energy right?
In dc it is always moves in clock wise direction then how it move in induced current to reverse direction .the dc is always moves in one direction then how it can move induced current as back wards
Please, watch again closely I thing you will understand then
Thank you
👍
Good work
Also keep videos related to civil engineering
Thanks for feedback
So what's the difference between an AC generator with a bridge rectifier and a DC generator? Nothing! Both have opposite magnetic fields, both have something spinning and both generate DC even though the AC generator generated it as AC first! Now I understand how Nikola Tesla came up with the AC generator! That's not as difficult as I originally thought! I can see where the Idea for the DC generator came from, this has all been done in a natural progression... The DC generator is actually an AC generator with the bridge rectifier basically intergrated into the design via the commutator! Hahahaha ROFL that's so easy!
Good video nice video sir good one
