Brushless DC Motors and Brushed DC Motors explained - BLDC Fan (2)

[@ThePostApocalypticInventor]

Hey guys! I just uploaded a new video about electric motors: kzbin.info/www/bejne/eaXYnYWnr9OVsKs

[@gw819]

I can't believe how much I learned in 22 minutes. I considered watching a different video to get a quick "brushed vs. brushless" explanation, but I'm glad I clicked on yours. The most efficient use of language. No "fluff", you presented the information extremely well. Subscribed. I will definitely be watching more of your videos when I have time. Thanks for sharing your knowledge!

[@BrokenLifeCycle]

Holy shit. Where were you when I was failing my physics class! This clearifys so much now.

[@latebloomer6957]

Hi there ...I took a 4 credit course in electric motors and controls ,this video was a good refresher ..... in less than 30 min you did a better job than the course I took for four months...thank you are you self taught

[@subjectmatteramateur16]

Awesome. I'm very excited to have a simple way to teach this to my children. I also knew nothing about motors before this video. I just purchased an all electric truck and am trying to modify the battery system from lead acid to lithium. With this and more of your videos I think that I can move forward with a higher level of confidence. Thank you and warmest regards.

[@ThePostApocalypticInventor]

Shawn Crockett Nice to hear that my video was helpful to you ! What kind of truck are we talking about exactly ? That sounds very interesting.

[@subjectmatteramateur16]

It is an all electric tiger truck.

[@Raj-nh3fc]

Thank you for a very clear descriptions of various motors. This was a real uplift after my high school level Physics some 30 years ago. You have a very good command of the subject and explain it very well with good diagrams. You sir are a very good teacher. Now i am ready to attack the brushless DC motor in my airconditioner indoor unit. I will be changing the ball bearing in it and won't be shocked any more to see that it does not have the messy carbon brushes that old motors had.

[@IamDerick]

You explained motors better than most of my teachers. I filled a few gaps in my knowledge. Thanks for your efforts. :)

[@jimmilne19]

Crystal clear educational video, very well recorded, edited and narrated. You got my subscription! Thanks for sharing.

[@1pcfred]

Is there a part 3? It was just starting to get good.

[@bucky222edwin]

Thank you for this great video. I was trying to understand BLDC motors and was not having much success with the information I had found. The length of the video didn't bother me. Just the opposite. I thought, maybe there would be something here that would help with my comprehension of BLDC motors. Now, I must watch the other videos you have gifted us with. You, Sir, are one in a million. Thank you again. BTW, I love listening to you speak.

[@tomthomas7126]

I stumbled across this video when looking for information on which type of cordless drill to buy for my next DIY project (current drill wont take a charge). Have to say, it was way over my head but I was drawn in by the enthusiasm of the presenter. The video is so well presented, explained in simple to understand terms and in superb English. I could listen to PAI all night and if I watch the video another 10 times or so I may understand the technology behind brushless motors. Thanks for a great video.

[@ThePostApocalypticInventor]

Tom Thomas Thank you. I'm feeling flattered :)

[@skillfulpeople]

Well done PAI, really down to earth explained and with lots of details almost to the atomic level. Good vibes from a trainee at the Pacific Coast of North America.

[@richardgordon9608]

Love your style. Great video. Well shot, well thought out. Just the right speed for me. Only the motors spun, not my head.

[@DaNiel-wj8qk]

as always finest lecturer quality, you are the best!

[@TheSageDad]

Most informative. I'm glad you give details and don't gloss over them... helps us newbies learn more of the technical side of things.

[@ThePostApocalypticInventor]

TheSageDad If one really wants to get into electronics, details are very important. Understanding the principles is of course the most important thing, but it is only the first step. When one wants to implement something in real life, detailed knowledge is mandatory and often a big portion of the work is basically solving detail problems :) Your name reminds me of this: SAGE - Semi Automatic Ground Environment - Part 1/2 Even though you sure meant something else :D

[@mark8664]

I am so glad your English is sooo good, I wish I spoke German as well as you speak English.

[@ThePostApocalypticInventor]

Mark Osborn Thanks. I'm feeling flattered :) But now I'm curious: Do you speak some German ?

[@mark8664]

The Post Apocalyptic Inventor Well English comes from German so I know a little that way and to from the old war movies :) but not in school.

[@ThePostApocalypticInventor]

Well that's better than no German at all :D I love speaking English and these videos are a good opportunity for me to do that. I don't meet a lot of native speakers here.

[@mark8664]

The Post Apocalyptic Inventor Why are you so friendly, your giving the German people a good name :)

[@ThePostApocalypticInventor]

Well I sure like to hear that ! I guess I'm not really a typical German. When I meet American tourists at local attractions, museums etc, I often have a little chat with them and we really get along quiet well. Those guys always say something like " Are you sure, you're really a German ?" They always seem to expect a somewhat more "blunt" and less polite behavior, as well as a general negative attitude towards life. And I guess many Germans must seem that way, when you meet them for the first time. Germany doesn't have a culture of "positive thinking", as it may exist in the US and many other countries. Also quiet some people value honesty over politeness. If you ask a typical German "wie geht's dir ?" ( "How are you ?") you will often get an actual negative answer like "well actually not that great...". Then they might even start to list all their issues :D. Most of my friends and relatives are that way. A friend from Scandinavia once told me that she found that very strange. She even disliked me for it when she first met me. It really opened my eyes how many of us must come across.

[@clydesight]

This is excellent! Thank you so much for making this video!

[@ArekSredzki]

Thank you for releasing such well produced videos. Your explanations are clear and concise, making them a great learning resource! This video was released a number of months ago, do you still plan on releasing Part 3 of this series? If so, when? Can't wait to see more content on this channel!

[@quicksilver40]

This information helps with the understanding of why BLDC motors have come along way in powering electric vehicles. Thanks.

[@DJSolitone]

I love the voice over last minute add-ons... They remind me of the good "Ost" days... Thanks again for your efforts. Your videos are truly amazing...

[@Mauromoustakos]

Many thanks for all your efforts. You are giving clear, step by step explanations, and with a clear voice. Well..., maybe a little slower will be better, since for many of us inglish is not our native language.

[@edwardhall1491]

Great video! Thank you! Hilarious at 15:10, Andromeda device, Flux Capacitor haha

[@georgelewisray]

Thanks for sharing. You have the ability to shine the light of understanding on the topics you touch upon. Did I already say 'Thanks' ?

[@jeffreyblack666]

One point some people might not get, squirrel cage motors and the like have an induced electromagnet, not one connected to a power source.

[@tobortine]

A very comprehensive and well informed video, thank you.

[@Bully000001]

Brilliant video. Your videos are always incredibly informative and your delivery and quality are first class. Many many thanks.

[@Good0Music0for0you]

Your videos are absolutely great , i learn so much , and i really like how you always give a very broad overview of devices and what applications they can be used for . Please keep up the good work , your fan from London .

[@chennemeyer]

Excellent video, detailed, with a nice mix of practical examples and theory seamlessly integrated.

[@tomwaters86]

Amazing. A lot of that was over my head but you explain things so well I learnt a huge amount. Thankyou!

[@ThePostApocalypticInventor]

***** I'm pleased to hear that. I already tried to keep things as simple as possible, but many complicated looking things (like magnetic field lines) are actually easier to understand than one would think, it's just a matter of "familiarity".

[@GregorOttmann]

The Post Apocalyptic Inventor I absolutely agree. Motors and magnetism still have me confused a bit, but the more videos of this kind I see, the more I actually understand. I f you keep doing those great instructional videos, I'll probably get all of it a some point or another. :)

[@aboldy]

Thank you for your videos I find them very detailed and informative. You must spend a great deal of time researching and preparing them. Thanks

[@Nivicoman]

I have had a phonograph with motor/transformer supplying a 3 transistor amplifier. I now have combination radio/phonograph/tape recorders with a.c. synchronous and capacitor start a.c. motors. Using on different frequency requires exchanging pulleys to compensate for the different rotation speeds on 50 or 60 Hz. All phonograph and tape recorder brushed d.c. motors also incorporate a speed governor consisting of centrifugal switches cutting in resistances to maintain correct rotational speed since BDC motors run at no certain speed. Then I have had many small BDC motors from toys, portable fans, drills etc. I have tested and serviced 3 phase a.c. motor softstarters using thyristors. In all I'm fairly well versed in a.c. and d.c. motors too.

[@mrpete222]

The explanation of motors I have ever heard

[@Bungagram]

Love your work. Please don't stop making videos.

[@Ecobion]

An excellent video, and I look forward to the follow-up.

[@Dude31463]

You can always tell someone's Mastery of a subject when they can explain it to anyone in simple terms as exemplified here... NICE :) Glad I came here... I was drawn by the beautiful thumbnail image of the stators that look like a Radial Engine, which in effect they really are. Would love to see one perfectly wound with gold wire. :)

[@wiatroda]

Another great video. Thanks for all your effort. Can't wait for a next part.

[@EvAnGeLiOn90]

it is so easy to judge someone else work. And that's the reason why I feel free to say that "kinetic force" is misleading :P I'm just joking and I found your video very interesting and educative :) Keep up the good work and thank you for making knowledge so easy ;)

[@louisehempston87]

Thank you so much for taking the time to make these wonderful videos and sharing your knowledge.

[@Joru666]

Excellent video, cant wait for the next part.

[@HeilmanHackatronics]

Great video on all types of motors

[@hellinas8]

I want to learn all this so badly! My next endeavor!

[@nigelhutchinson5028]

"and I don't care what any of the free energy idiots is telling me.." LOL oh man I diiiieeed. Thank you for putting that in there, made this video even more legit than it already is! Great stuff, great info.

[@mareksumguy1887]

I love you man. You know exactly what you're talking about.

[@kutupbear]

man i love your accent, crazy German scientist xD thanks for your time and effort in making these videos, please keep it coming

[@justmycomments]

Excellent presentation! Wonderful and very educational.

[@dronai]

Questions- On a PSC motor- Single phase, with a capacitor start motor- AC condenser, blower motor application 1) If you disconnect the cap, what if you tied the brown to the brown/white together to leave the start winding in the circuit, without the cap ? 2) Does this kind of motor leave the start winding in the circuit the whole time without damaging it ? 3) What kind of unit uses a CURRENT relay instead of a potential relay, to drop the start winding out ?

[@VerifyVeracity]

there are some really great little motor used in the Remote Controlled Airplanes. And the controller are not to be forgotten either. Thanks for the video I'm going to watch it at least one more time. :)

[@pokejam5433]

Thanx, I realy like your way explaining technical processes and interactions

[@godofplumbing]

I learn a lot from your videos.. Thank you

[@Banzay20]

thanks for some great info! In your intro you show a clip of what looks like a circular magnet approaching a circuit board and a led lights up, where can I find it.. need to know, plz. thanks!

[@ThePostApocalypticInventor]

+Banzay20 What you see in the intro is basically an early version of the device I presented in this video: kzbin.info/www/bejne/Y4u3dIR3j9iCqZo

[@centralzonetvtanzania7313]

Nice practical explanation

[@beverlymargolis369]

Very ingenious, congratulations! I hope that you continue to manufacture those so one will be available when I've saved that amount. That would be ideal for my limited needs as I seldom travel more than 20 to 30 miles in an average week. Storage and charging would be the easiest thing in the world. Even though I live in a relatively safe neighborhood, I could just park it in our outside storage building. Again, congratulations on your incredible achievement!

[@ABritInNY]

+Beverly Margolis I'm confused what product you are talking about? the video was a DC motor tutorial! are you sure you're commenting on the correct video?

[@davidglithero4712]

Excellent video enjoyed watching it and your very clear explanation, thank you

[@creativemindz07]

Excellent. Thank you for a very nice educational video.

[@EngineeringNS]

"I dont care what any of the free energy idiots are telling you, it is not possible!" hahaha I love it!

[@paulwhelan3228]

Question- I am checking a brushed DC motor used as a fuel pump. It has 8 commutator segments and uses permanent magnets. I am checking the amperage draw on the motor using a current probe. My question is, when is the motor current draw highest, when the brushes are directly on the commutator segments, or when the brushes are bridging two segments? Thanks!

[@Matt-jy2vg]

This video is amazing. Thank you for making it.

[@georgestan123]

Great information! Keep up the good work!

[@vlupis1]

15:05 comment on free energy freaks was so hilarious, i like it :-)

[@DragonsREpic]

Im looking for scooter/mopeds and elderly scooter DC electric motors all I find is industrial and large fan motors for A/C units. I might be interested in R/C prop motors later on. But I don't know anything about them.

[@peerfunk]

sehr geil erklärt obwohl ich das eigentlich alles weiß habe ichs trotzdem angeschaut mach weiter so :D

[@deangreenhough3479]

Thank you for another excellent video

[@freedomfinch7952]

with your accent and its a little hard for me to understand u at times but regardless I wanted to say thank you for being the best person ive found for explaining this to me. thank you. :)what accent is that anyway? just curious

[@ThePostApocalypticInventor]

Freedom Finch I'm German. Where do you come from?

[@leonard3k]

Hello and thank you for all it took to make this video. Just found and subscribed. I played with brushed motors n solar cells, buzzers, step up xformers, speakers etc when I was a kid. Love this stuff. Now being in the RC Airplane hobby, I am getting more interested in wrapping some motors and later making a brushless motor controler. I am very weak on electronic theory but study these things and then do them. Sometime I want to try building a hi efficiency brushless motor for airplanes with a larger diameter so more torque would be achieved with less power or current. Larger dia motors would maybe see better use as pushers because of the drag unless a larger spinner is used for tractor ( pulling ). I have allready seen some of these and they are quite expensive and have very low kv ratings. I would like to find something to wrap a motor with outer can diameter of say 2 - 2.5 inches to spin a 12 x 6 prop at about 10,000 rpms on 11.1 v lipo using a regular motor controler and hope for current of like 5 amps or what ever. A fun project, more efficiency, something hand-made. Put it on back of a Saab J21 or Vampire pusher or forward on P51 Mustang. Any ideas where to look to achieve this without re-inventing the motor or the wheel or reading "War and Peace" to do it. Info like this seems fragmented piecemeal hard to find. Any ideas, anybody else allready doing this? Really like your video and theory explanation, used to work as a tech now a pipefitter but I love this stuff. Thank you.

[@purenight77]

will there be a part 3? and how you integrated it all into your forge, i am actually replacing my air source in my forge too. Great video thanks

[@ThePostApocalypticInventor]

Callum Stewart I will talk about that soon, as I have now started to work in the basement and with the forge again (as you can see in my latest video) . I had some health issues in the meanwhile, which caused some delays.

[@babylonfive]

The Post Apocalyptic Inventor Best regards on the health issues... we look forward to more motor and basement updates!

I really appreciate the effort you give to make such a great video. Respect... When will be the coming video for the control unit?

[@jordanscoville4839]

awesome vids boss, AvE sent my your way and I'm glad he did...got some more to watch, but relay good formats. ..and S.T.E.M...

[@kraig800i]

Which type of motor would you suggest for an Electric motorcycle conversion? Currently I'm considering a 10 HP manta 2 motor but might not be able to get it. Where would I get a good alternative if I can't ?

[@Jm4steam]

good video. thanks for thorough explanations.

[@afterthought138]

Excellent work! Thank you!

[@stanilastefan1687]

Hey this is a very good video. I would like to pick your brain about a way to measure the output mechanical power of an motor, as i see you have a very inventive way to see things. Thanks.

[@ThePostApocalypticInventor]

Stanila Stefan You have to connect the rotor shaft of the motor that you want to test to the rotor shaft of a DC motor and connect an adjustable dummy load to that DC motor. The DC motor will act as a "generator brake". The only thing you have to do then is to measure the voltage across the pins of that DC motor, as well as the current flowing into the dummy load. Then you multiply that voltage with that current and you will get a power value. You then only have to correct the result by multiplying by a correction factor, that compensates for the friction losses. You would then simply vary the supply voltage of the motor under test, as well as the size of the load until you have found the MPP (maximum power point) of that motor. The motor will produce different levels of power depending on its supply voltage and the size of the load.

[@stanilastefan1687]

The Post Apocalyptic Inventor Sorry for misleading you. Is not about dc motors it is about high power 3 phase motors powered at a single phase line. I am trying to find the right capacitance for the maximum mechanical energy output. I am thinking of a jig that can measure that since i can't rely on measuring maximum power consumption due to the breaking effect of to much capacitance.

[@ThePostApocalypticInventor]

Stanila Stefan I guess you didn't understand what I said. This method can be used to test ALL kinds of motors. the DC motor is not the one to test, but it acts as a GENERATOR that is connected to the motor that must be tested. The DC motor is acting as a generator that generates a dc voltage that is proportional to the mechanical power delivered by your 3-phase induction motor. If I could make a drawing you would understand it, KZbin comments are not suited to discuss matters like this :D

[@stanilastefan1687]

The Post Apocalyptic Inventor Got it, use another DC motor as "dummy load" good idea. Thanks!

[@williamwazere]

I have been systematically going through all of the videos publicly viewable on this channel over the last week or so. From this I noticed that a part 3 to this series doesn't exist yet, unless I have missed it. Is it on the way or has it been shelved since part 2 was published 6 months ago? Nice series though, had some information confirmed and learn plenty more, thanks for producing videos to such a high quality! I think the only videos I have left to watch are SMPS series videos. I have only watched part 1 of that so far. I even have a couple videos saved away in a playlist to watch again as they covered information or ideas I want to really absorb.

[@RLNTEX]

Great Lecture! Thank you very much.

[@AnanthuAchary01]

very good one................ and it is very healpful

[@StuartTaylorEsquire]

Thank you for another excellent video. did you know you have a catch phrase? ".. since this video is already too long" - you could have split this video in two. the 1st half is valid as tutorial separate from your brushless fan controller project. Mit freundlichen Grüßen

[@ThePostApocalypticInventor]

Yeah I konw. I keep repeating that same sentence... It seems I just won't learn how much stuff can be put in one short video. Originally I wanted to make just one video, but part 1 and 2 combined have now over 30 minutes of length and I haven't even spoken about the actual circuits yet...

[@latebloomer6957]

Need info on how to cool a minn kota trolling motor outside of water , using motor for my velomobile . Because the trolling motor is brushed pm I will use it for regenerative braking application ...thanks for your time and thanks again for the vid and especially the way you explained the aligning of the fields , reminds of electron flow theory and conventional flow for calculations .

[@proyectosledar]

Hola, comento en español porque vi que entendes. Excelentes videos en calidad y claridad son todos muy interesantes de ver. de donde sos? saludos

[@ThePostApocalypticInventor]

Proyectos LED I live in Germany, but I produce my videos in English so that as many people as possible can watch them. I can understand very little Spanish, but I had several years of Latin in school, which hepls me to figure out, what Spanish, Portuguese or Italian sentences mean :D. Kind regards !

[@proyectosledar]

The Post Apocalyptic Inventor I completely understand, I do also like to make my videos in English but I'm not good at it :) the Spanish do not pay much :( You're doing an excellent job.

[@Rocker1lex]

Holly shit man! You´re really good :D I loved your video.

[@VicAM83]

Great video with more info than I know what to do with. I am trying to figure out which motor would be best used for a small electric go-cart. When you mentioned the stepper motor, I believe so said that one required complex driver circuitry. Does this refer to a micro controller or something? Any info at all or even being pointed in the right direction would be greatly appreciated.

[@ThePostApocalypticInventor]

Stepper motors have several stator windings, which need to be switched in successive order periodically . The switching sequence must be delivered by some kind of control circuit. That is a job which can be done by several different topologies, one of them being a microcontroller. In order to drive a large stepper motor (as it is required in a go-cart) however, a driver stage must be added between the control circuit and the motor. microcontrollers them self can only deliver a few mA of output current, to drive a stepper motor of that magnitude several Amperes will however be necessary. Driving a universal motor for example would be much simpler. But then again you would need a reduction gear in any case, since a universal motor would most likely not supply enough torque without one. The same goes for the other classic types of electric motors. You might also need some kind of step up converter (a boost converter, push pull converter, full bridge converter or similar) to increase the battery voltage to a level the motor is rated for. It is not an easy task, though I'm sure that there are go cart people out there who already found a solution for this.

[@VicAM83]

The Post Apocalyptic Inventor Wow, thank you for the info and thank you for the quick response.

[@carlyleroberts3995]

Excellent video well done !!!

[@yoannthomann]

awesome ! Do you know which motor is the best to convert into a generator, and how to do this ?

[@ThePostApocalypticInventor]

+yoann thomann It depends. In which application do you want to use a generator? How much power do you need? what is your source of mechanical energy? How high is the frequency of revolution of your power source? Is it going to be for charging batteries (DC) or for direct connection to an AC-grid?

[@yoannthomann]

I would like to use it for a wind turbine (vertical axis), an for a small water turbine. I would like to produce around 1kw with each. I would like to produce DC for my batteries.

[@ThePostApocalypticInventor]

+yoann thomann Then none of the motors shown in this video are really well suited for your application. The problem is, that VAWTs have a very low frequency of revolution at comparatively high torque. Since the frequency of revolution is so low, you will need a motor with as many poles as possible. Otherwise the voltage induced in the generator will be very low and the power output minute. Furthermore you should use a motor with permanent magnets. The washing machine motors in this video have field windings though and an external power source would be required to even magnetize the stator pack. The small Brushed-DC motors shown in the video can be used as generators, but they also require high RPM, they have a limited life span due to the commutator and the maximum power output is much lower than what you want. The only motor type (salvageable from household equipment) that I know off, that would be somewhat suited is this type of motor, that can be found in special types of washing machines: kzbin.info/www/bejne/hH3EhJmVjr5qjtU

[@whtstr2133]

+The Post Apocalyptic Inventor I prefer car alternators, but I have yet to convert to 120 ac 60 hz. I don't know if it will survive. The reason for the choice is the powered stator being adjustable in strength. Altering stator power and RPM can tune in a certain power output. Replacing brushes with slip rings in a universal motor can do the same task. Electro-magnets have the advantage of an adjustable magnetic strength, and can be adapted to the torque supplied. Another reason for the choice is the car alternator uses the battery to power the stator core up to the point in which it becomes self-sustaining. Then it becomes the generator for the car battery, and can be quite efficient at higher rpm. I believe you refer to the High Efficiency Washing machine motor, a three phase AC motor. I've been eyeing ceiling fan motors as well. However, some people prefer to re-wire these. I like your collection, it is a vast array of motors. My collection isn't even half that. It is very impressive.

[@whtstr2133]

60 degrees. wtf is virtual EMK. I calculate in Gauss-EMF.

[@mah0100221]

Thank you for this amazing video, I wonder if you could give some information about the magnet material, are they easy to find and is that also easy for casting?

[@zerofactor7871]

What would be a good motor to use for a pulley system? I need something as low-profile as possible yet very powerful, and simple enough to control with a weight/touch-sensitive processor. I am very new to all of this and I am attempting a simple project for personal use. Any help is appreciated.

[@ThePostApocalypticInventor]

Thom Stoops It depends on what you want to do of course. But I would say you need high torque and a low frequency of revolution. A (brushed) DC motor with an integrated reduction gear, would be a simple solution.

[@zerofactor7871]

Thanks a lot, I will research this further.

[@malgailany]

Excellent video!

[@infinity2012rmx]

2 permanent magnets as "stators" could be used, if They are driven by another Motor (e.g. 2 stroke engine). They wouldnt be that static anymore tho ;)
