DC MOTORS AND GENERATORS - Department of Defense 1961 - PIN 29942 - DESIGN, APPLICATION, AND OPERATION OF BASIC, SERIES, SHUNT, AND COMPOUND WOUND TYPE DC GENERATORS AND MOTORS.
i think its because its hard to make a video back then, so they have to think it through and revise every detail before screening? whilst now i can just pick up my webcam and explain.
+cok Bagus That is true, but some of the newer videos involve the creation of detailed 3D models and animations that also take a long time to produce, and they still can't hold a candle to these classics.
the dumber the population, the more it is dependent on the state. Therefore, it is in the interests of those employed by the government to make education as shitty as possible. Government must be removed from education entirely.
The reason these old vids are so good, is that they were training films for young men enlisting or being drafted into the military. We rely on these young people to maintain our submarines,tanks, etc. They kept it practical and basic to get you into the field quickly.
@Tbone productions It's very good through about 13:30, then crashes and burns. The leap in background required to follow along jumps enormously, so that you have a very basic, sound video for the first 2/5ths, then a preposterous digression into shunt wound generators, then we go back to simple battery and magnet demonstrations around 17:40. Strange video indeed, but worthwhile in many respects.
the dumber the population, the more it is dependent on the state. Therefore, it is in the interests of those employed by the government to make education as shitty as possible. Government must be removed from education entirely.
I was in the military and all their training videos are still like this. Very intuitive and direct, they set training on a step level and repeat information to drive it home and make it easy. I was in the Marines. It is good ya know.
I often seek older information sources regarding basic principles for their explanatory simplicity and their lack of reliance on unnecessary gimmicks such as cumbersome and overwrought animations. When I was teaching electronics years ago, my go-to video series was The Mechanical Universe and Beyond. The math might be a little thick for those uninitiated to calculus--especially in the episode on Maxwell's equations, but the animations are clean and perfectly complement the narrative.
I owe a debt of gratitude to the older generation for this......none of today's computer generated videos can match the quality of this instructional film....it's just so well presented and clearly explained. .., this old film taught me more about motors than any other crap videos put out on TH-cam.
guys, can we just take a minute to appreciate how well the animation was produced, i mean look at the rotors, mags, commus and current flows, it has everything and looks so familiar. can you believe they made this in the early 60s? just wow! and conceptually it did a good job as well, it conveyed every bit of info modern graphics can deliver, and i'd say it did even better than a lot modern ones. but, on another note, this probably cost a lot of tax money, and i say it's well spent... :b
This video is pretty amazing in that I am currently taking Electronics and Physics classes at night and the content in class is so convoluted that it is difficult to pull the simplicity of the presented material for comprehension. example: "The postman is walking, he is stepping at 75 steps per minute and each step is 150 cm high. If he had magnets on his toes and the ground was made of copper. he would create voltage. That is how generators work" That, of course, was an exaggerated example but yet not too off par.
This way of showing the schematics of a DC motor/generator is way better than the way my book try to explain, which is kind of more complex. This is exactly what I wanted as I wished to know the functioning before going ahead to the equations. Thanks!
This is one of the most concise explanations of this I have ever encountered. The military didn't mince words, these videos had to be on point and clear. Just as relevant some 60 years later.
Absolutely wonderful videos. They're more fun and educational than most other videos I have seen so far. I am currently learning how motors, generators and electricity work as a whole and your videos are exactly what I needed. Keep them coming.
Love these types of videos. You just dont find it anywhere in today's teaching where they would explain in simple terms and actually takes the effort to let us understand. Inspite of the usual boring stuffs to just explaining it and leave it for the "bright minds" to understand they do think about "us".
Why are old books and videos so much better than the new stuff? I just gained more understanding in 35 minutes than I did in a whole semester of circuits. Thank you for sharing.
this is the best video I have ever seen I have a class on DC machines and DC Motors and with this 30 min video I learned more and more than 3 months we spent in the class
High school student here. Found this light-years more helpful than my physics teachers and worksheets. I doubt they even know what they are talking about half the time.
this is insane. Will be using this to learn some of the basics that have eluded me. But it's shockingly instructional. And the best part is I can always rewind and watch something I didn't quite get
This sort of video we did actually have in school in a few classes...good teachers realized it was a good way to learn. I'm always thankful of my shop class teachers for that.
because was made for military people, that have to be faithful to the flag, but not required to be scientist or graduate; they have to learn the essential in very few time. these video should be used in every college, the quality is very high, because was made by the State for his personnel. The market is another thing...
I have worked with direct current motors for years and never could have understood the relationships of the parts. I change brushes because of sparking- never knew what I was doing or why. Now I am getting a better idea. Finally, I'm getting electric motor education. This is so cool to me.
When education that dates back 50 years ago is better than current education today. You know that our coming generations are fucked. Seems like every teacher I come across always has contradictory, or missing details. These videos clear every question that I have. It's quite amazing.
@ 8:45: now you know why we studied trigonometry! This is the clearest explanation of sinusoidal electrical waveforms I've seen on YT, and it's been around 50+ years! Were have I been??
This video is better than any other new video published on this topic and that's why all of us watched till the end.I hope to watch many interesting videos on this channel..mm yah. 😊 hope you guys continuing.Thanks for this video! wish you all a happy new year with glee.🎡
Even though this video is old , but it's like years a head of it time ... it was very clear and simple , my 6 years old brother could understand it easily . PLS more documentaries like this and thank you so much for taking the effort ..
Work in a mill that still uses MG sets for all of our DC motors and speed control. Such old technology but still reliable to this day when properly maintained
I was just about to post exactly the same thing unsure if I was missing something, then looked down and saw your comment and realised you'd beat me to it. Good spot!
THIS VIDEO IS AWESOME I've known how Ac and Dc motors work but didn't really have a clear understanding of them.OUT OF ALL THE VIDEOS AND BOOKS I'VE READ THIS IS THE BEST THE keeps you from being confused all the time :D
I aggree with all other comments. Really fantastic how a so old video coudl be lots better than any actual university course! How many years back is the education today! Videos like this are lacking today for the understanding of science and technology!
Excellent step by step demonstration, for young men handling motors, or anyone trying to invent. (Can magnet force be placed to produce motion or current without visible input of motion or current? It must come from somewhere, but spinning electrons are gates to "other" quantum space, so the "system" is not as closed as it appears.) It's notable how tricky elements of a simple DC generator or motor are! Once, it wasn't obvious how to do this. Now it's not obvious how to tap "free" energy.
@JaySmith91 Yeah i noticed that too. The right hand conductor rule where your fingers point in the direction of flux and your thumb points in the direction of current flow is opposite here. Also flemmings right hand rule for generators and left hand for motors doesn't work because of the mistake with the current flow through the conductor.
Starting at 25:00 this video explains very clearly how a train, subway or streetcar starts. For stop and go transportation DC is the most efficient. For long run, high speed transportation, AC is the best, higher voltage through thinner powerlines. Both AC and DC have their (dis)advantages for public transportation.
why do these old movies do such a great job at explaining vs new videos???
i think its because its hard to make a video back then, so they have to think it through and revise every detail before screening?
whilst now i can just pick up my webcam and explain.
I think you are correct. I would love to see modern day remakes. Same script new graphics.
+cok Bagus That is true, but some of the newer videos involve the creation of detailed 3D models and animations that also take a long time to produce, and they still can't hold a candle to these classics.
these classic versions are presented as practical knowledge where new versions are often presented a theory.
because making a video back then was a big deal only people who really knew what they were talking about had a chance to do it
Holy Crap, This is exactly the knowledge that I have been searching for. Why isn't all education this straight-forward and simple?
Right on :-d
the dumber the population, the more it is dependent on the state. Therefore, it is in the interests of those employed by the government to make education as shitty as possible. Government must be removed from education entirely.
These days, they dont want educated inventors. They want skilled workers.
Sam they sure did a crap job at teaching you spelling
The reason these old vids are so good, is that they were training films for young men enlisting or being drafted into the military. We rely on these young people to maintain our submarines,tanks, etc. They kept it practical and basic to get you into the field quickly.
100% truth, comment liked.
@Tbone productions It's very good through about 13:30, then crashes and burns. The leap in background required to follow along jumps enormously, so that you have a very basic, sound video for the first 2/5ths, then a preposterous digression into shunt wound generators, then we go back to simple battery and magnet demonstrations around 17:40. Strange video indeed, but worthwhile in many respects.
I have a class on this. learned more in this video than in class for 2 weeks and reading the book. The layout is more logical. Quality.
That's pretty cynical. I like it!
the dumber the population, the more it is dependent on the state. Therefore, it is in the interests of those employed by the government to make education as shitty as possible. Government must be removed from education entirely.
Welcome home, oh based one. You have much to learn.
I was in the military and all their training videos are still like this. Very intuitive and direct, they set training on a step level and repeat information to drive it home and make it easy. I was in the Marines. It is good ya know.
I hope they try to keep the old school style and big band intros and outtros.
The best thing I've seen..This summarized my four year of engineering school.....
really? did you get your degree at motor state university?
If you visited school once in 4 years that might be true
It blows my mind the dumbing down of the world. We have modern CGI, yet these old videos from the past explain everything so much better.
Sometimes old things are better than new things.
I often seek older information sources regarding basic principles for their explanatory simplicity and their lack of reliance on unnecessary gimmicks such as cumbersome and overwrought animations.
When I was teaching electronics years ago, my go-to video series was The Mechanical Universe and Beyond. The math might be a little thick for those uninitiated to calculus--especially in the episode on Maxwell's equations, but the animations are clean and perfectly complement the narrative.
The Mechanical Universe and Beyond I must now check out. Simple & Oldschool FTW
Nikola tesla 😍😍😍😍
like Sergio Reis said:
old pot makes good food
I owe a debt of gratitude to the older generation for this......none of today's computer generated videos can match the quality of this instructional film....it's just so well presented and clearly explained.

These old videos are extremely informative.

I second that my textbook is complicated too had to memorize the equation without fully understanding whats going on.
This was very helpful. I love the style of explanation in these older docs.
I love these old training videos. Thanks!
This is one of the most concise explanations of this I have ever encountered. The military didn't mince words, these videos had to be on point and clear. Just as relevant some 60 years later.
I love the style of these old videos!
look along the right edge of the film, looks like the projector is full of lint and hair, gross lmao...
I never appreciated how complex DC motors are before this video.
Absolutely wonderful videos. They're more fun and educational than most other videos I have seen so far. I am currently learning how motors, generators and electricity work as a whole and your videos are exactly what I needed. Keep them coming.
Wow, these old videos are a throwback!
This just proves that knowledge never gets too old.
This is the BEST explanation video i had found so far!!! thumbs up!! covers everything i want to know!
Love these types of videos. You just dont find it anywhere in today's teaching where they would explain in simple terms and actually takes the effort to let us understand. Inspite of the usual boring stuffs to just explaining it and leave it for the "bright minds" to understand they do think about "us".
This is probably the best video for understanding these complex topics in no time
Why are old books and videos so much better than the new stuff? I just gained more understanding in 35 minutes than I did in a whole semester of circuits. Thank you for sharing.
this is the best video I have ever seen I have a class on DC machines and DC Motors and with this 30 min video I learned more and more than 3 months we spent in the class
Great stuff ... from a time when value was put on accuracy and clarity of understanding ...
Wow, Yep, totally the best instructional video I've had on generators, and I'm an EE major!
Love it!
couldn't agree more!
these old videos explain things brilliantly! its a shame the talent of making them has been lost :'(
High school student here. Found this light-years more helpful than my physics teachers and worksheets. I doubt they even know what they are talking about half the time.
this is insane.
Will be using this to learn some of the basics that have eluded me.
But it's shockingly instructional. And the best part is I can always rewind and watch something I didn't quite get
Esses vídeos são muito bons em ensinar conteúdo rapidamente e de forma intuitiva, da forma que eu gosto.
Old is gold these types of videos needs to be made a thing again
This sort of video we did actually have in school in a few classes...good teachers realized it was a good way to learn. I'm always thankful of my shop class teachers for that.
Superb! Well explained and extremely valuable regarding the informative level! We need more of this!
i dont know if this narration is so good because it was the millitary or because it was 1960. either way i like it
because was made for military people, that have to be faithful to the flag, but not required to be scientist or graduate; they have to learn the essential in very few time. these video should be used in every college, the quality is very high, because was made by the State for his personnel. The market is another thing...

Best of all videos available on this topic, very well illustrated. Thanks for such a nice thing, very helpful
Old school cool and very comprehensive...I will seek this video again.
Clearly explained without hiding facts. Thank you sir.. One more.. Continue this channel same manner.
Thats the best explanation i have ever heard! Great presentation!
When education that dates back 50 years ago is better than current education today. You know that our coming generations are fucked. Seems like every teacher I come across always has contradictory, or missing details. These videos clear every question that I have. It's quite amazing.
Now I understand it clearly. thanks! you are a very effective teacher.
I was trained in electronics in the US Air Force. I saw videos like these - many produced by the U.S. Army and U.S. Navy.
It summarize my whole semester for DC machines . Great vid. Well explained topics . Thankyou somuchh
old is gold.......hence proved....
this information is golden......succinct and straight to the point via the facts...... perfect for any student
@ 8:45: now you know why we studied trigonometry! This is the clearest explanation of sinusoidal electrical waveforms I've seen on YT, and it's been around 50+ years! Were have I been??
I just love those old videos !
This video is better than any other new video published on this topic and that's why all of us watched till the end.I hope to watch many interesting videos on this channel..mm yah. 😊 hope you guys continuing.Thanks for this video! wish you all a happy new year with glee.🎡
this video literally just covered the unit I was reading for elevator school. good timing and good video.
how simply they explained A to Z about DC motors and generators !!👍👏🇮🇳🌠😁👌💎
Excellent information, this is REAL education old school style.
Who is this Ryan
Truth please
Simply the best now I can get to business and try to make my own!!!
These videos are gold!
Desrves to be watched more than one time ! Thank u
w Allah yehdina
Even though this video is old , but it's like years a head of it time ... it was very clear and simple , my 6 years old brother could understand it easily . PLS more documentaries like this and thank you so much for taking the effort ..
Les anciens sont plus savant que ceux d'aujourd'hui ......... 👍💌
These old explanations are the greatest. (See differential working.)
Best video explanation I've seen so far, thanks for the upload
Simply superb .This video is made nicely such that it is not necessary to listen to class room lecture or refer to any book on dc machines
hey i got this video in my engineering course last year. best video out for gen and motor!
Old school is the best school i have worked with some old timer and i learn so much with them
I am impress by watching your videos." Really compatible"
A finest study material I got after searching through many Videos. A great video which explains the theory precise.
excelente vídeo! Obrigado por compartilhar.
maaaaaan I love these old videos!
Work in a mill that still uses MG sets for all of our DC motors and speed control. Such old technology but still reliable to this day when properly maintained
Good stuff real simple to understand and straight to the point 👍
best tutorial of dc motors and generators in my life
The best of the best. 1960's documentaries rules!!
Old but Gold still the best explanation about Generator I really love it
OMG we use this and I never thought this would be online!
finally this black n white video has added the true colors to my knowledge... thanx
Brilliant video this...REALLY helpful!
wow this video is excellent. The animations are great. Very well explained.
it is the principle of electricity generation in clearly.really thank very much and we wish more like this video
The best thing about this old documentaries is the voice, it's just epic
Eh, the voice isn't twinge inducing like Seeker, but the content and organization is where its at.
I was just about to post exactly the same thing unsure if I was missing something, then looked down and saw your comment and realised you'd beat me to it. Good spot!
THIS VIDEO IS AWESOME I've known how Ac and Dc motors work but didn't really have a clear understanding of them.OUT OF ALL THE VIDEOS AND BOOKS I'VE READ THIS IS THE BEST THE keeps you from being confused all the time :D
I aggree with all other comments. Really fantastic how a so old video coudl be lots better than any actual university course! How many years back is the education today! Videos like this are lacking today for the understanding of science and technology!
you kind sir,made me like and understand this "stupid" (as i thought it be) lesson.thank you wholeheartedly!
Old School Rocks! the best.thanks grandfather!
wow i am in love with this explanation Thanks
the best way to understand dc machine mechanism...............thanks..
thank you for this video . ..God bless. . .
This video is suprisingly informative, I liked the way they explained armature reaction.
Excellent step by step demonstration, for young men handling motors, or anyone trying to invent. (Can magnet force be placed to produce motion or current without visible input of motion or current? It must come from somewhere, but spinning electrons are gates to "other" quantum space, so the "system" is not as closed as it appears.)

AS USUAL EXCELLENT WORK THANKYOU SO MUCH FOR YOUT TIME AND EFFORT
GREAT food for thought. This stimulated some new ideas. Thanks
Who is this Al?
As soon as i saw this was a black & white video, i immediately saved it.
Excelente aporte. grandioso.
I love these old educational videos
really felt very good better than most of present lectures
Thank you. This taught me allot.
I learned a lot from these films in science class in 1954
dhe end statement by the commenraror is profoundly important, Understanding them is important.
Awesome video! Thank you!
