wtf... u know what? i've been searching the interactive video like this about dc motor and so far i found this as the best explanation video i ever . AWESOME , thanx a lot for sharing sir.

[Axmaddaahir]

awesome, nice video

[damrak1969]

I enjoyed all of your DC motor videos - thanks!

[amrsymphony]

ur really a grt instructor i hav visited the link its really helpful thank you

[parjanya1512]

be proud of your accent bro.......do not apologise...:P :D

[sureshkumarbeee]

usefull one

[sureshkumarbeee]

useful one

[anamtaj]

i wish u had explained the basic terms such as rotor stator shaft etc

[Oodelify]

You just saved my skin. Thank you so much for this video! It helped me to finish my alternator assignment. :)

[minhaz33]

bro what software do you use?

[culturacolombia]

Thank you !

[deimos540]

Hey, there's nothing wrong with being Greek. The Greeks basically invented Western Civilization. I am quite serious, and have studied this for decades. Without the rediscovery of Greek learning the Renaissance might have been delayed by 500 years.... I am Irish. The Greeks came to Ireland in the early Middle Ages.

[willraytaylor]

The over-simplified DC motor has a very bad desgn fault.

If the carbon brushes are wider than the gaps in the split ring they will touch both sides of the commutator split ring and so the electricity will short circuit If the carbon brushes are narrower than the gap in the commutator the motor will work, but may stop with the carbon brushes over the wider insulator gap and so not start the next time.

[pcbheaven]

@willraytaylor i thought that by uploading subtitles, i was not going to get this message again... Once more: the over simplified motor is NOT a real model, it is only to explain how it works, because if i was to put 3 magnets, it would be many times more complicated without doing any good. After all, this video is part of a theory page (which you may visit) in which i explain what happens to this motor and how this is solved.

[BRANDONSUPREME]

Thank you. I'm planning a small generator for my science project. However I needed more power because I'm going to use it to charge a device via USB. To charge I needed a DC. The motor is a great solution and your explanation is very easy to understand.

[tunesbook]

dirty english pronounsesation

[cuoo123]

i like ur language u speake like germany.very good accent.

[DjJohhnyIsAtLive]

would there not be a small short curcuit when the bushes pass over the gap on the commulator, since bothe brushes will be temporarely on the same side??

[pcbheaven]

@DjJohhnyIsAtLive yes, but i explain this in my site. this video is to support my theory, you should read the theory as well.

[pcbheaven]

@DjJohhnyIsAtLive and also, this is the reason why i say that a real-life dc motor does not have only 2 electromagnets ;)

[davidrobert2007]

Great video thanks!

[tridenteng]

Nice video and very good diagrams.

[cubidpro]

waooo nyc work man



[TheWednesday96]

you sound so handsome with your accent. I'd go out on a date with you and just listen to you talk :-D

[jiawkose]

great video!

thank you

[boomy818]

hey i have a question.. how do i power my 110v dc motor from a foot massager to a 12v car batterey?? will it work if i just connect the positive and negative to the car battery?? i want to make a scooter

[pcbheaven]

@boomy818 you need an inverter

[gollumondrugs]

@pcbheaven inverter converts DC to AC

[pcbheaven]

@gollumondrugs yes indeed, and then you can convert it with a transformer to any voltage you want.

[gollumondrugs]

I think the clue is in the motor description! It is 110V motor, not 12V. Change the motor or change your power source.

[harleyjamesg]

Great videos! What software are you using?

[pcbheaven]

@harleyjamesg inventor

[MiserableSht]

Can someone tell me what the parts of a DC generator are and what they do, its for engineering coursework,

[el08aay]

I really liked the 3D way of explaining the material, I admire you sir :)

[bmxstreetking6666]

the mad scientist from iron man 2 accent!

[ebrahimebram]

thankyou so much, it was amazingly well explained, except the last part I think you meant permanent magnets are fixed, not the electromagnets, are you italian

[zangarkhan]

Thank You

[masterofsurges]

Very useful video. It helped me a lot! Thanks! :)

[alextex27]

the motor ur build doesnt work i real life, if u look closely u have tow coil how can that creat a rotation, beside when that motor rotate it join the positive and negative wire that will cause the power supplie to dicrease in voltage fast. u dont know what ur saying

[pcbheaven]

@alextex27 go to my page and read

[JoeP3rks]

Thanks! I like how you explained it from the inside out.

[MultiSmartdude]

good

[HiTec84]

NICE !thx

[joyedwards100]

Hey dont worry about your accent, you sound like Russian, but you have a heart and willingness to share what you know with the world and that too free, that makes you a great person, with your animation your presentation is well understood, if someone says they dont understand they must learn alphabets first.

[tribble921]

@joyedwards100 Well said

[piper4seeformerly]

I took apart a small DC motor and the permanent magnet is one piece, not split into two crescent shaped halves. What's up with that?

[pcbheaven]

@piper4seeformerly test it with another magnet and you will probably find out that it has 2 poles opposite each other

[utkt91]

nice

[dladyluck2]

Can't understand 1:42. What doesn't happen in real life?

[Verradonairun]

@dladyluck2

This is what I believe he says:

"The motor has actually 2 electromagnets...something that does not happen in the real life."

[Kikkan87]

Nice video!!!!

[farhalathif]

can please explain about placing armature windings and connections with commutator segments...

[kiwi9062]

Thanks man!

[MUHAMMADHAMZA430]

can u tell me why the brushes are made of carbon? why not copper or other conducting material? please reply

[pcbheaven]

@MUHAMMADHAMZA430 for carbon can withstand friction, while copper would wear out. i explain details n my website.

[MUHAMMADHAMZA430]

@pcbheaven GREAT MAN UR AWESOME. IS THAT COMPOUND GRAPHITE OR SIMPLE CARBON CAUSE ONLY GRAPHITE IS THE CONDUCTOR IN ALL FORMS OF CARBON

[pcbheaven]

@MUHAMMADHAMZA430 i am not sure. i suppose it is graphite, but there must be different materials as well

[srinivas797]

can u tell me wat software are you useing to make that motor

[pcbheaven]

@srinivas797 autodesk inventor

[pcbheaven]

@srinivas797 autodesk inventor

[srinivas797]

@pcbheaven thanks man

[srinivas797]

thanks man

[virlusun]

thanks so much for making this awesome video. you explained so well!

[pcbheaven]

@tailsmilesprower24 visit my website to read the theory

[ObamaIsMaBabyDaddy]

Im not good with motors. Can someone tell me if i supply the spin to the motor without the battery, it does not need the battery right? i Was going to make a magnet motor and connect the spinning somehow to the DC motor and then that would convert it to electricity to power a lightbulb.

[UsperKrephus]

You were absolutely right about the way of explanation. It is much more informative to see a motor getting built, instead of looking inside a finished piece. And dont worry about your accent, I got used to it very quickly.

[acika72]

i love you man ,i have the same DC motor is only 3cm :D :P !!!

[srinivas797]

Super and clear demo greate vedio

[enaarnaki]

This video was extremely helpful! Thank you very much!!!

It would be really great if you could make also one video about the AC motors :)

[amper0003]

Excellent Video, thanks a lot!!

[sjjumani]

what soft ware did you used?

[esotericwars]

i dont know anything about motors but can you explain what causes them to go bad/burn out ?

[pcbheaven]

@esotericwars if not an over current that toasts the coils, usually the bearings wear out. In case of brushed motors (like this one) the brushes wear out much faster.

[1123aka]

Subtitles please !!!

[coolerooney1]

Nice vid, good presentation ;)

[Nanometer45]

i need subtitles!

[minus080]

nice one thanks a ton!!!

[eastcoastflush]

that was so clear...now i really understand !!!!!!!!!! i ve seen many videos ... for understanding fully i recommend you to watch other videos and at last watch this...then youll gonna know everything about this type of motor!!!!! THANKS

[danieljusticiero]

good very good, exelent job

[scottmd73]

Great video, we normally call the "cover" the bell end, in the electrical trade anyway.

[pcbheaven]

@scottmd73 thanks for the remark mate!

[brianation]

what program is that ?

[harith2016]

cibai cant download

[MedyumMemis]

Your video seems very helpful but I must say that it can get difficult to follow your English. I believe your videos would be twice as educative if you had subtitles. Thanks though!

[puzzleboxed]

I understand a lot more about electric motors now. It was useful thanks. =)

[Pachan84]

Very good explantation! Thanks for that

[aedus17]

Great!

[znotis07]

bravo re megale..!pragmatika me boithises! thanx!

[Sougandhpavithran]

Excellent Explanation too good. Keep it up.

[TeacherPhilEnglish]

Great video. Very nice model!

[spongebob1872]

ive disassembled one and all it is copper wire being spun by and electromagnet nod by electromagnet i mean copper wire surrounded by magnet ( + and - ) and electricity being attacked to both magnets thus its spin!.... loll :P

[sonofdracula]

thanks thats the best explanation ive found so far, crystal clear, but why do i see on some motors coils also around the permanent magnets? do you have more on electric motors?

[pcbheaven]

@sonofdracula Yes this happens as well. An AC motor for example can have this arrangement. A brushless motor also could have the rotor as described.

[shortiorti]

@sonofdracula Are you sure they arent pole pieces instead of permanent magnets?

Because the coils around the pole pieces together with the pieces create the electromagnet.

If they were permanent magnets there would be no need for field windings.

[gtalc03]

thank you very much

[SISMUMBA]

Thanks, it helps a bit...I hate this chapter I still don't understand everything about it :(

[pcbheaven]

@SISMUMBA It is easy! I suggest you go to my website in the corresponding (look the link in the info of this video,)

[SISMUMBA]

@pcbheaven Okay..thanks a lot. I hope this info helps me in my grade 10 board exams :)

[pcbheaven]

@SISMUMBA why don't you go to the website and read the theory?

[haidertipu54]

@pcbheaven THE CREATOR OF THIS EDUCATIONAL MOVIE (FOR LAYMAN LIKE ME AND MANY OTHERS) IS A GIFT FROM HEAVEN. WELL DONE AND KEEP IT UP. YOUR PRONUNCIATION AND ENGLISH IS PERFECTLY ALL RIGHT AND IT DOESNT MATTERS WHAT THE ACCENT IS. WHAT IS IMPORTANT IS THE GUIDANCE YOU HAVE PROVIDED TO MANY.... THANKS FROM ME
