I agree. It's amazingly clear.

Thank you so much

[@RaviSharma-xt4py]

ATTENTION: The current deflection is maximum when it comes to the horizontal position and zero when it comes to vertical.

[@chrvoje_engineering]

Yes, I must change this

[@mahalingama4162]

and so we use multiple coils

[@user-rf5fc6om3l]

why is that?

[@tbhargav8477]

Tq ❤️

[@PipenFalzy]

You still haven't changed it. If your going to explain things it needs to be correct.

[@webmaster246]

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 :)

[@chrvoje_engineering]

[@gfield6765]

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

[@chrvoje_engineering]

Yes, this is mistake

[@Lumpify.]

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.

[@saimali7470]

You mean right to left. Not left to right.

[@TheLarsonator]

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.

[@chrvoje_engineering]

What part of the video

[@bibeknyaupane7066]

for minimizing such defect commutator can split in many parts so that gap can be reduced

[@book19118]

You cleared my concept thank you.

[@chrvoje_engineering]

Glad it helped!

[@abishekc4862]

Make the video about, in which position of the conductor the induced current will be maximum, whether in parallel or perpendicular to the conductor?

[@chrvoje_engineering]

Thanks for idea for topics

[@uvelectricalengineer1220]

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......

[@chrvoje_engineering]

es you are right, rhis is made opposite I will change this preatty quickly

[@MrForbinator]

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.

[@chrvoje_engineering]

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

[@MrForbinator]

@@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

[@chrvoje_engineering]

@@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

[@chrvoje_engineering]

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.

[@chrvoje_engineering]

I think that Im right but....

[@tickyul]

My PhD is in Feline-Neuropsychiatry.......but I still have a hard
time with this....thanks.

[@Flash.flash.flash77]

Thank you sir for the explanation .its very helpfull to my education purposes . I subscribe and like your channel.Again thank you

[@chrvoje_engineering]

Thank you

[@kumarshubham142]

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.

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

You say flemmings right hand rule, but isn't that flemings left hand rule ?

[@aditg847]

Left hand rule would show the direction of magnetic field the right hand shows force which is what’s required in a generator

[@chrvoje_engineering]

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

[@rybautista1716]

Fleming's left-hand rule is used for electric motors, while Fleming's right-hand rule is used for electric generators.

[@vanimashetti1108]

I didn't understood how the current is reverses can u pls reply me

[@manjuagrawal5831]

Split rings or commutator is used to reverse the direction of current

[@Rrrrrerrrrrrrrrrrrrr]

It should be Fleming's left hand rule not right hand

[@sethsoumyaranjan29]

Right hand for generator and left hand for motor

[@tarunraj1868]

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)

[@chrvoje_engineering]

Yes you are right, I need to fix this but I will do in remake of this video

[@beingooljalool]

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.

[@hiprompt7036]

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.

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

[@PeterMilanovski]

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!
