Interesting how no matter how crappy the old educational video, there will be endless comments about how much better things "used" to be explained and how stupid everything is now. I'm not putting down this video. It was fine. I just think it's funny how I could throw up an educational video of anything, and as long as it was black and white, poor video quality, and in an "oldtimer" American voice, it would simply be of a higher caliber than anything we could make THESE days. Damn I guess this makes me a troll. Try not to be so predictable though.
It's better not because it is black and with with old american voice,etc,etc. It's better then most because although today we have access to 3D generated models and other software to help us, most of the modern videos would overwhelm the viewer with different angles of a generated 3D model and processes going in front of each other, rather then laying everything out neatly, or helping the viewer understand by showing a simple version of the solution and then scaling it up to the real thing. The problem with most modern videos is the approach taken to teach the viewer not the quality of the videos.
I love these old-timey videos...they explain everything so clearly and always give you a fundamental understanding of the concepts involved so you REALLY know how the thing works.
Mоdеrn day ѕtаrtеr motors are dirесt сurrеnt еlесtriс mоtоrѕ with a starter ѕоlеnоid that drаw сurrеnt frоm a bаttеrу. manyautosltd.com last month fixed my car motor and at that point i knew all about the technical aspects
I love these old educational videos. They're so detailed with relevant information and give you different visualizations of how the mechanism works. I always learn thoroughly from each of these videos
My compliments on those who worked on this education video. they made the didactic material mith so much cure, they explain it way better than those on virtual programs nowdays. Thanks!
This presentation is one of the best I have been as it is very clearly explained in details and not presented in rush mode or with hip hop tunes, like many seen in today's presentation, which detracts the concentration. The narrator is also excellent.
These old school documentaries/videos are far better than the modern ones with clearly understandable English. They explain from the first principles and you get real engineering concepts as precisely as possible. I need more of such videos
The explanations here are remarkable. I've seen other videos on this channel and the ones from decades ago describe things I've always wondered in ways which I can grasp mentally. They really had a knack for simplicity back then. Thanks to the people decades ago who came up with this technology and clear explanations on how they work. They changed everything for the better.
I teach high school Physics and most of my high school students don't have much mathematics background, so I have to Present Maxwells Equations with some English sentences that explain the meaning of the 4 Differential Equations. Next I am going to use this video to show a practical example of how the Maxwells Equations can be used in the PRACTICAL "REAL" World!!
I am fascinated by the props they made to demonstrate the principles. I would love to work on designing props like that. Of course, these days most props are made using software and are realistic animations. I've made a number of props for teaching purposes over the years but the one I am most pleased with was the De Broglies Electron Diffraction device I built using a laser instead of a diffraction tube. The real thing is very expensive and my version cost less than $40.
+Feel cool now, bro? being able to explain something using clear accessible language is the key, I actually managed to pass my automotive electrical class thanks in no part to the mandatory 600 page textbook that over explained every little detail. I had to discard it and go with a straight to the point, 100 page study guide that covered all the same stuff.
+Justin Noker See it in a business/professional perspective (the big boys). To make profit you gotta "change" what was easily comprehended, but it is displayed as improvement to the mass. Improvement display professionalism. Now that the lecture is improved & professionalized (w/ bigger grammars); it is sophisticated which people are attracted to. All in general, overtime we transition to "commoners vocabulary" (for the mass), as for the high class are taught w/ sophisticated grammars (which the high class see as common words), but media (in favor of the high class) commercialized it as professional. This is how we keep you "thinking" you're stupid & you will "never" make it in this lifestyle I have designed
My HS electrical shop teacher's explanation to our "How?" and "Why?" nonstop questions was to take a hammer and smash capacitors,resistors,batteries etc into pieces. "Stop asking how every single thing works and just know that it does." I think the saying "Can't see the forest because all of the trees." was his meaning.
Wow this is amazing.. I never knew this.. ppl were so intelligent back in the days.. why weren't we shown this as kids.. I don't even know how I got here..lol
There is a mistake. It is not the wires that become the North and South poles of the loop, it is the openings. For that singles loop motor to really work, the brushes need to be horizontally opposed.
You are absolutely correct. The simplified motor model description in this tutorial is wrong and a misleading part of the movie to a serious student of the subject. I was wondering if someone caught this major error. As you correctly observed, the magnetic poles should project out of the plane of the coil and not the edges (the polarity determined by the right hand rule etc.). The model department must have gotten carried away with the glass tube neon light coil model which I admit looks really cool. In a real series wound starter motor the brushes are skewed (timed) off of the theoretical neutral brush position to compensate for armature reaction (google search this if you are interested). A serious RC model enthusiast would appreciate this.
This is great video about motors but it doesn't go over the unique characteristics of starters at all. Starters cannot run for large lengths of time because of the "exceptional power output for their size." They overheat quickly. Starters are also connected to two very important things. A solenoid and a bendix. The solenoid is a linear motor that moves a lever that moves the bendix against the flywheel. A bendix is a very special set of grooves, spring, and gearing that allow the starter to connect into the flywheel. It 1) prevents the starter teeth from jamming into the teeth of the flywheel if they're lined up wrong (the bendix rotates slightly), and 2) it prevents the starter from staying connected once the engine is moving faster than the starter (as the engine is moving under it's own power at that point). If the starter were to remain connected once the engine started, it would overheat the bearings.
Waww.. 50s kids are lucky.. they have got some clear idea on the core principles than us in 2020.. That could be the reason some real serious inventions are happened at that time
Maybe they used a digital camera to take photos of drawings, then it gets transferred to a computer. Check out how Disney's Snowwhite and the 7 Dwarves film was made.
When I learned electromagnetism at school when I was a child I thought about how I could make a motor by switching the poles, I was sad to learn it had already been invented.
So interesting reading user comments on UA-cam these days and noticing how today's crappy politics seeps into EVERYTHING. Liking this video = wanting the good old days? Not necessarily. To me, these videos are helpful because they spend a lot more time on the basics. Today's tech is so much more complex there often isn't time to do that. I'll watch this and then combine it with a modern video to get a fuller understanding
Movies tell us that sometimes cars can take more time to start than usual. Is it true or just plot nonesense? Is there some conditions that would make the car need more time to start?
When the direction of the current (and this may be obvious, but I'm not sure) he literally means that, right? So how is the direction of the current changed? Sorry if it's a dumb question, but I'm not sure i'm clear on that.
intresting how this 1900s video explain more clearly than 500 modern vids
yeah and even Air Conditioning.. i have seen 1900s more clearer than today
Louis Henn exactly
very true

Came to see how a car starter works, left understanding fundamental electromagnetics and motor physics. Beautiful.

the big issue with modern "documentarys" is that they prioritize run time heavily over being concise and easy to understand
Wow. This made sense without hurting my head. Gotta love the old school.
I love these old educational videos. They're so detailed with relevant information and give you different visualizations of how the mechanism works. I always learn thoroughly from each of these videos
My compliments on those who worked on this education video. they made the didactic material mith so much cure, they explain it way better than those on virtual programs nowdays. Thanks!
This 10 minutes was better than a whole semester of physics (electromagnetism).
Yes is true I understand it better than 5 year at university
ua-cam.com/video/slGWNxRi1ZE/v-deo.html
I've been trying to understand this for an hour. Then I get to this video and wham! Thank you so much!!
I've watched so many modern documentaries on the electric motor but still never fully understood it until I saw this. awesome
you could literally go through 10,000 people these days before finding someone who could explain as clearly and concisely as they did back than
These videos are so easy to watch.
matching with your profile pic
This presentation is one of the best I have been as it is very clearly explained in details and not presented in rush mode or with hip hop tunes, like many seen in today's presentation, which detracts the concentration. The narrator is also excellent.
Patrick Murphy
our parents/grandparents had it easy back then, education wise
straight forward to the teeth
Now I understand why Documentary Tube is Best ever at explaining theories in Vehicle engines. I like this channel.
You can't beat these old documentaries. They are excellent instruction videos.
extremely good and detailed video, way better than anything you find theese days.
These old school documentaries/videos are far better than the modern ones with clearly understandable English. They explain from the first principles and you get real engineering concepts as precisely as possible. I need more of such videos
This video is a lesson for all those online tutorials around
Excellent presentation!
Till date nobody explained as simple as this video. Thanks a lot.

what a beautiful, concise and elegant explanation of something I never thought id understand in my life

Next I am going to use this video to show a practical example of how the Maxwells Equations can be used in the PRACTICAL "REAL" World!!
I fell asleep in class many times to this old school instructor voice back in the 80s.

Great video. I now understand how the electric motor works.
I love these types of videos. They make it so easy to learn.
Why is it older documentaries did it better, I mean, they really start from the beginning and don't have it dumbed down too much
I agree, I'm taking automotive, and I got way more out of this video than the one we watched in class about starters.
luvgzus4ever good thing you told me that, i'm taking automotive next year lol

This is how we keep you "thinking" you're stupid & you will "never" make it in this lifestyle I have designed
Because everything explained "to the point" rather than making it commercially.

"Stop asking how every single thing works and just know that it does." I think the saying "Can't see the forest because all of the trees." was his meaning.
My response to that is, “It’s gonna break, right? So how can we fix it if we don’t know how this works or why that does what it does?”
Amazing explanation! Wish modern videos could explain things as clearly.
Why do starter motors always fail to start the engine at an inappropriate time in horror movies?
because the motor is afraid.
Because it uses plot battery hence it won't start.
That's must be it.
Peter Peter Scriptwriters.
Due to the magnetic field of the monsters.
Fantastic. Need simple explanations done exactly this way. Love the old style, too. Wanna keep that, as well.
How did bro from 1953 explain this better than anyone else
wow... just wow. this is easy to understand, it begins with the basic first, very good approach for a complete clueless individual like me.
Wow this is amazing.. I never knew this.. ppl were so intelligent back in the days.. why weren't we shown this as kids.. I don't even know how I got here..lol
Very easy to understand!!! Thanks for sharing this video. I advice you to share more like this video.

That's correct. You can see it at 3:29 when they put iron feilings on the acrylic plate.

Chris Katko they'll get it right on their next video, oh right, they're dead so there won't be more videos.
thanks for the comment, I literally asked the question after I finished the video
Chris Katko True they get hot fast. One could water cool field but armature would burn up.
When this video was made, the mechanical solenoid and the gear protector wasn't invented/used yet.
I actually wondered about that, thanks.
That being said, I think they did a great job of explaining the mechanics of it.
This is what should be shown in my class so people will actually know how they work
better than any modern animation , as far as explaining is concerned
I think we appreciate these old videos more because they are intended to educate the most ignorant minds
Good one ,class rooms doughts are now cleared , amazing video
What an exceptional explanation! Thank you very much
अद्भुत तरीके से ,, salute...... thanks again
10 minute video more efficient than years of schooling
I hope you upload more videos about mechanical and electrical sir, i like the way you explain👍💯🙏🏻
Bro I love these retro type educational videos :D
Mesmerizing.... How clear explanations!!!
One of those old is gold
very awesome video !!!! loved it. helped with studying
This is a great documentary
Amazing. If only everything was taught this well.
I learn so much from these videos thank you
Wow! Its so amazingly explained.
excellent sir
i am learning so much...
thank you for your uploading video
Great video! Thank you so much for this!
i think weall take engineers for granted
icyburger And horses.
Ryan Kreder random
Waww.. 50s kids are lucky.. they have got some clear idea on the core principles than us in 2020..
That could be the reason some real serious inventions are happened at that time
Better experience and the correct engineering
this is better than modern day school
This is better than today’s education
I'm wondering how they made those animations back then.
obviously stop motion
Maybe they used a digital camera to take photos of drawings, then it gets transferred to a computer. Check out how Disney's Snowwhite and the 7 Dwarves film was made.
wow zers LOL!
All hand drawn. Filmed one frame at a time on a stop motion movie camera.
Thank So much.
From Colombia.
Regards.!
Very well explained...good job
Maravillosamente explicado con todo lujo de detalles.
Excelent explanation plenty of details.
nice work man
dobro objasnjeno, bravo
The iron core in the center of the motor and poles increases the magnetic fields strength.
I wonder why this video was made. Also, why was it put on you tube. Nonetheless a very good video. The simplest things are so elegantly designed...
When I learned electromagnetism at school when I was a child I thought about how I could make a motor by switching the poles, I was sad to learn it had already been invented.
Fluffyhead Lol you’re only like 80 years too late
Is it really happened at that time? Such a difficult way to start the motor. Thank god we have technology.
Why old learning more good explained then the modering and even helpful .
EXCELLENT EXPLAINING you have earned
Any more videos from these guys?
So interesting reading user comments on UA-cam these days and noticing how today's crappy politics seeps into EVERYTHING. Liking this video = wanting the good old days? Not necessarily.

Its amazing explanation man 😁😍😍😍😍
this explanation is brilliant. I hate modern explanation
we need remastered version
Very easy to understand 👌👌👌👌
old is gold...
Isn't this the same guy that explained the need for Differentials and how an open-diff works? (the video with bikes doing circles in the beginning)
Now I realize why the Bendix is so important, but that will be another video just for it.
Wonder why modern car does not come with hand-cranking lever in case the battery ran out.
Amphol Traisathit Jumper leads?
dobiem1 Forgot to mention when there isn't any other car around to jump start from,too. :}
Amphol Traisathit
In that case...... push the car forwards and then jump into 2nd gear lol
Dobie, what if you have an automatic?
Justin Noker
Then, he's f*cked.
Movies tell us that sometimes cars can take more time to start than usual. Is it true or just plot nonesense? Is there some conditions that would make the car need more time to start?
486 still couldn't grasp it, no matter how simple this video was.
very interesting.useful for engineers
Good vedio.... Malayalees like here🙋
Holy shit i just learned a lot
Can anyone tell me how old the video is? Because this simulation at 6:37 seems pretty sophisticated.
Excellent
When the direction of the current (and this may be obvious, but I'm not sure) he literally means that, right? So how is the direction of the current changed? Sorry if it's a dumb question, but I'm not sure i'm clear on that.
I love this video
best explanation ever. millennials and generation whatever, here you go
Ordinary Soul ,💀👻👻👻👻💩👿💩👹👹🎃🎃🎃🎃🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🔦🙇🏻🙇🏻👈🏻🙇🏻🙇🏻👈🏻🙇🏻🙇🏻🙇🏻🙇🏻🙇🏻
Well, are grandpas can explain this matter much clearer than any computer generated graphics. Lol
How does the pinion move forward to line with the fly wheel?
wow amazing bro.
Yes..it is amazing but any how you need to understand the principle of magnet & magnetism
I opened the video and i said waste of time... after 10 minutes i said No wayyy. Don't mess with old school.
wow keren,, sekarang bendix pakai listrik juga ga di injek
Question! Can a bad/ failing starter cut off a running engine suddenly ?
How can one make this machine?? The one with the glass that goes from clear to white on one side
