I am an electronic engineer . I have more than 20 years experience in electronic and electric industry though have never stopped refreshing my knowledge in this field and in the other science . I want to tell you dear Jeremy that your approach to explaining the electromotors structure and functions are very useful for beginners and even for the experienced people .Thank you .
I watched this video months ago, trying to learn all I could, not knowing how useful it would be for me. My mother wants a serger sewing machine and I found a very nice one local to me for a decent price with the caveat that in order to get the motor running, the handwheel needed to be turned. I knew that I remembered something from this video was relevant so I came back. I now believe I have isolated the issue down to being that capacitor or a starter winding and I haven't even seen the machine. Thank you for helping me make my mom happy!
Constant voltage through the footpedal fried the starter winding. I fixed it and I owe it to this video.
I think people going through more academic channels of education highly, HIGHLY undervalue demonstrations like this. You da man.
4:18 ..."if you hooked them up backwards... uh, you'll have a bad day" Love it.
me too
Not if you're electroboom
I giggled quietly. 🤣
Isn't that called "releasing the smoke"?
Two things went pop when you first plugged in a circuit board - a reversed electrolytic or a shorted plastic transistor. Some early line drivers for core memory (see, I'm an old fart), too, when being stress tested. The line drivers would shoot up a little flame.
I loved that. Forget about flashy animations. Just a pen and paper and an actual motor. Brilliant explanation.
You have an exceptional gift for instruction. You're a good smooth, well-inflected speaker; soothing to listen to. Best of all though, you convey the sense of wonder necessary. My family always laughs at my preoccupation with these "little" elegances and ingenuities. If only they knew how such things make the world go round (yes, intended).
Thank you for the kind words. This means a lot. As to the "little" things. Not many people notice what they are, but they notice something is missing.They might say "he is a bad teacher, but they couldn't say what was wrong. Perhaps the teacher lacks genuine enthusiasm, or pace, or simply doesn't recognize the gap in knowledge between the student and teacher. Or worse, the teacher has another motive and has no real interest in the student learning. This works the other way as well, and that is what you are noticing... "something is good". Personally I think it is a skill to pick up on such tiny details... the effective ones that is. Thank you again!
Definitely agree. I really enjoyed watching parts 1-4 of this series and I sort of wish it went on to talk more about motor science. Absolutely fascinating.
Jeremy Fielding You are soo right about a teacher “may” have “other motives” than the student being taught. That point rite there goes so far in so many fields... I believe “Incentives” given to build or broaden “certain fields of employment” could be the blame for soo many shortcomings in the fields of “higher calling” such as education and medicine and of course politics and the ministry.... I wouldn’t be surprised if you have a military background though I see masses of young ppl enlisting to serve our country and their only reason is for the benefits that serve themselves.... In ranting now and I apologize lol but your thoughts do tend to invoke much thought into others... But it’s a problem we face and I’m not sure I have any solutions to offer...
On a diff note, I imagine the pulsating of a single faze Moyer has much to do with the myth or maybe fact that many of housewives of years past left alone with their washers found that the old trusty Maytag could be a helpful companion during lonely times!
100% agree

I've tried viewing other videos explaining this type motor but yours is the only one worth the time. You actually know how to communicate! A rare quality in the majority of youtube attempts! Thanks
Quality video. My teacher told us to watch this for homework.
Mr. Fielding, your videos are exceptional...you have a gift for understanding technical things, and also to explain them. I started watching your videos about two weeks ago. I kind of understood that AC motors worked because of a rotating magnetic field, but didn't really understand. Thanks to your vid's and the old military training videos you linked, now I know so much better how they work. Fast forward to this weekend. My outside A/C unit quit working. It hums but the compressor/fan are not running. My first thought, thanks to what I learned from you, was this sounds like a capacitor problem. Sure enough, in my unit, the fan and compressor share a run capacitor. I tested it and it is definitely bad. So, 12 bucks on Amazon and a new capacitor is on the way. I am 99% sure this is the problem. But I would have had no idea if I had not watched your videos. Thank you!
6 years later and your video has helped me learn about the Single phase motor. Thanks for the breakdown and diagram. The details you point out makes a big difference for what to look for and understand.
Hi Jeremy my name is Mike, and I got into electronics about two years ago. Since that time I have constructed a full blown electronics lab in my basement, and also have been collecting motors and lcd/led displays. Until now I felt intimidated to break them out and try to power them (reverse engineer), as fear I would fry them. As it seems every tutorial elsewhere so far it seems he/she always leaves something out to where I abandon the motor project because it leaves that little "well what if" or just not confident of motor knowledge. But after watching all your videos, I'm going down in to the lab and grabbing the meter and start banging out some pinouts.You definately have a gift of teaching and sharing your enthusiasm of motors, as I watched each video I sat there nodding my head, just as if I was there standing there in your shop...as I recognize all the motors, names, and most components of motors already, you banged the theory home and something clicked and I am pumped up!!! Thank you so much Jeremy, now is the hardest decision which motor to drag out from a collection of at least 60....take care and thanks again!! Mike.
Thank you for the kind words. I am so excited hear you how helpful my series was to you. Since this was just about exactly what I was hoping to accomplish... my job here is done :)
wow i think im finally starting to understand this stuff ,i have brushed and brushless motors im my rc cars but never quite understood the how and why parts ,you are the laymans best bet for gaining some understanding of the mysterious.. thanks man
There needs to be more people like you! Honest people that more passionate about learn and education rather than profiting.
I am not a good teacher by any means, yet I have held quite a few 'classes' on theory of physics, it is not easy! Hats off to you because you teach me quite a bit, you are in "layman's terms" a Gr8 teacher by nature. A real gift.
I really love your videos, I have learned so many things I have always wanted to know. They are very well structured and the information is very clear. Thank you for putting the time and effort into making these.
It is so nice to be educated by someone who truly knows his field. It's evident that not only do you know your stuff but also very passionate. Great video.
It's great that you appreciate and point out "ingenious" engineering. I was an industrial mechanic for about 15 years and respected many of the machines I had to repair for the way design problems were solved.
I feel the same way. I marvel many times at the simplicity of some great designs. I know from what I do, that many sleepless nights can go into an idea that is so simple you can't believe how ... cheap, easy, simple and yet functional... etc it was.
There's some clever people in the world. Then an awful lot of dead weight.
@@1pcfred Yeah unfortunately dead weight tends be noisy and gets all the attention
That's humility and admiration, respect if you will.
@@JeremyFieldingSr I need a wiring diagram to run this electric motor! It has 6 black wires come from the motor which is labeled T2,P,C.C and P and T1 is connected together. Any help will be greatly appreciated
These videos are the simplest explanation on CZcams great job my friend great job
Great description of the shaded-pole motor. I've never really understood how it works until now. Thanks!
This is the best explanation of single-phase induction motor operation I have ever seen! I retired from electronics engineering after a 40+ year career. I had a very basic understanding of single-phase motor operation from my college training, but being in the circuit design area, I never really thought about it again after college. Now I understand it well enough to actually troubleshoot a motor problem AND be able to explain it to someone else (at least someone with a long enough attention span to listen to the explanation). Thanks for this very clear and thorough tutorial.
"This capacitor is polar so if you hook it up backwards, um... you're gonna have a bad day" hahahaha! Laughed my ass off. I just love your videos. Very thorough and clear. You would make a good teacher/ professor.
It's been 23 years since I had my electricity training in technical school. Most of this was review of what we learned there, but it was presented in a more concise and understandable way than our teacher did it. I don't work with electricity every day anymore, so there was a lot I had forgotten, and I also learned quite a few details that had never been presented to me before.
You have a gift for instruction, and your respect for the ingenuity involved in the invention of these motors comes through. What seems simple and basic to us now that we know how it works, took some very smart people years of head scratching, lying awake at night, and time-consuming trial and error to figure it out in the first place.
Kudos to them and to you sir. Thanks for these videos. I will use them for my own review and also to introduce my grandson to these concepts in the future.
I've been working around motors for years but never quite got it about how they worked. Your explanations worked phenomenally well for me. Thank you!
I'm in school for hvac and electrician, you video is very informative. You have simplistic way of expressing your knowledge and I can hear your enthusiasm while you explain operations of the motors
These ‘homemade’ vids are more informative and easier to understand then most full production scholastic created videos. I just watched 3 other vids made for educational presentation, and learnt more in your’s then in them.
Thank you so much
Jeremy, It astounds me there isn't this level of practical knowledge given to EE students. While I could spend hours telling you about the equations of magnetic flux, back EMF, torque, speed and estimated losses, nothing compares to this level of understanding. Power electronics needs to be taught very differently. I salute you for teaching this old electrical engineer something he missed all those years.
Amazing descriptions of how these motors work. I am definitely NOT an electrical engineer but have been fascinated by the very questions you answered here. I so appreciate your video's and you are very kind to share you extensive knowledge and put it in such simple terms a layman can understand. Thank you.
CZcams
you have a really good way of explaining things, never getting too far ahead without explanation, well done man and good luck
Your a natural teacher. Love your videos!
I've had a vague understanding of how motors work for a long time, but watching these is like lifting a veil of mystery that was covering my eyes. I never knew what that click when a motor slows down was until now! I can't thank you enough for taking the time to present this information so well.
Currently a grad student in Electrical engineering. I never realized that the dryer switch is what connects the start capacitor! That's genius! Also explains why when I don't press it long enough the dryer doesn't start up
This is really good when he talks about the rotating magnetic field in the rotor that causes the motor to rotate, focusing on the rotating magnetic field in the rotor. It brings the concept all together.
I cant believe it.are you a wizard!?somthing about you is special you past my mind's firewalls with first word.
I watched a number of videos and read a number of articles on how induction motors worked and got nothing from them. I probably would have understood if I was live and could have asked questions. However your video was extremely informative and I finally understand this easy concept. You really have a knack for explanation. Thanks much.
Thanks so much for this series. As many times as I've tried to learn about 1 vs 3 phase power and about motors in general, or had it explained to me, nothing has been as clear or stuck in my head as well as your last couple videos.
You are a gifted teacher, I love how you show both theory on paper and how the device actually mechanically works. That is how I learn the best! Thank You
took a lot of training in Army Schools, never got this kind of great education on motors. JF you are great teacher, like you say not expert, not in my book. Thanks
Brother! YOU are amazing.
You have explained the subject in such a way that someone with a reasonable knowledge of electronics will know what it takes to make a motor work.
You have also given great examples of the uses of the various motors.
I salute you.
I feel like if I watch all your videos I will be an expert. great job!
I'm about to finish my masters in controls, I'm watching your videos to remember all the other things they taught me at E.Eng school they're full of practical information I'm lacking :)
Want to thank you for teaching about motors. A lot of people go through this life and never know how it works, but you do such a great job teaching. I wish you the best. A new subscriber.
Appreciate your explaining my dryer to me. Will do a load of laundry now and enjoy it more.
I'm trying to crash course for a job, your videos are really fun to watch thank you
You, sir, are a great maker and an extraordinary instructor. Your kids are lucky; few of us have the opportunity to grow up in such a wonderful learning environment.
Superb! I was in aviation tech training to pilots for many years; you are easily on a par with the best instructors I encountered. You have a knack for conveying the key points without going too deep into theory. Easily the best explanation I've seen on the shaded pole motor.
I m an architect but still enjoy and learn from your videos
I’m an electrical engineer and your videos rock
Want to thank you for taking the time to share your knowledge. As I’ve read in some of the other comments, I think your a great teacher and explain things extremely well. I’m an Industrial Electrician Apprentice and these videos have really helped me get a much better understanding of the topics you’ve gone over. So again, great job and Thank You!!!
incredible 4 part video explanation. these motors are truly amazing engineering feats and i appreciate your teaching style. thank you for explaining all this!
Thaaanks for the lesson! It's been over 25 yrs since I have worked with induction motors. This helps me get back into it again.
Great explanation very thorough and delivered in a way that makes it easy to remember. Great refresher, it's been many years sense I covered motors during my HVACR classes.
Your videos are amazing, it takes me back to my college days in basic electronics and in my electrician apprenticeship program. You teach very well and you use the perfect examples.
Great Job !
Thank you Dr. Fielding! Your simple, clear explanation of how to clean the contacts on the centrifugal switch on a single phase induction motor. You may or may not possess the actual degree, but in my book you are the motor Doctor!
Just started learning how DC motors work in an elective class. These videos help a lot. Very clear presentation. Well done.
Excellent video, Jeremy explains complex electrical theory in easy to understand terms with the aid of using simple diagrams & motor models. He has a natural talent of introducing a "Breath of Fresh Air" into the world of electrical engineering. Thank you.
Thanks, that was the first explanation of a shaded pole motor that I could actually understand!
I really enjoy your content, you are clear, informative and very helpful.
That was really well explained. I knew the capacitor did something special. Now I know exactly what. Thanks for taking the time to explain.
If you are not already a teacher you should be. Thanks you very much for explaining the workings of the single phase motor...most valuable.
You are an incredibly talented educator. Thank you for these videos.
Excellent video! I've been going through a bunch of single phase induction videos, and this is the first one that clearly explained how to get that initial rotation. Thank you!
I am glad you found it helpful!
You are awesome my brother from another mother.Great videos, your a great teacher.
It still feels like "kid first time learning this magical things" wonderment sensation. I see you again today. Thank you. Bsafe God bless.
Man’ ur a teacher. I would’ve known about the start and run windings’ the understanding of it is what us thought me; thanks 🙏
I just happened to stop by this explanation of an induction motor. No doubt you have some kind of magic that engages audience. Keep up your great job.
You are a very good teacher, everyone would like to have a teacher like you !!! ( Thank you very much ) !!!
New to motors. I fixed 1 this morning. "Bad spring on brush". Decided I should know more. I saw 1 of your video's&I subscribed. Like it.
Thank you, and welcome to the neighborhood!
Best explanation I've heard for manually kicking an induction motor, and the fact that a single pole can be hand spun in either direction (without the start cap and winding).
you have talent in teaching...you knew how and what to do in order for the students to learn...keep it up..
Jeremy you are my go to guru on most things electric motor! I'm in the midst (thank you Covid-19!) of a career change. Yesterday in class my instructor walked us through various motor types and their mechanism of operation. When I asked why they're called shaded pile motors he said he didn't know but we could make decent $$$ replacing them when they broke! 12 minutes with you and I can tell him how they work in my next class! Thank you Sir!
The way you explain things is just amazing. You make it very easy to understand.
The best CZcams video on how capacitor helps run a/c electric motor. Thank you!
Wow, great explanations. I learned more about how my motorcycle electrical system works by watching these videos than hours of pouring over confusing wiring diagrams and trying to trace different colored wires.
A fantastic set of very informative videos,thank you for taking the time and effort in making them.I could listen to you all day no problem.
I am an electrical engineer and your videos rock
Amazing! Thanks for the lecture. You are always explaining the important parts of the subject.
I've watched these twice! There awesome thank you for the walk thru on motors.
I'm not one to be given instructions to do something and aimlessly do it. I have to know the theory of what makes it work. Thanks to you I now have a different level of understanding of a single phase motor and related start capacitor. And the shaded pole. Many thanks, I am truly grateful. Please keep up the good work. God bless you.
GAHHDDD this is rad. The small fan motors ingenious way to kick off is mind boggling.
Your practical explanations are pure genius, thank you.
Thanks for all your work on this you're a great teacher God bless you my friend
you're an absolutely awesome teacher! Thank you!
Well i dont know how i miss this Channel ( your videos) But i must say OUTSTANDING !!!! This is hands down one of the best videos i have seen on single phase motors. Bravo good job. Let me just say Thank you Sir i am looking forward to watching the rest of your videos.
Absolutely superb instruction. I now understand the functioning of single phase motors and shaded pole SP motors. Thank you very kindly.
I think I watched like 5 times already! But I’m just amazed at how that fan is able to move. Like what a genius way of solving that out of phase problem
Videos are helping a lot with my Electrical Technology Program.THX!
Being a student thid video has happened me understand how motor operate. Thank for this video
Thanks so much for this series of videos. I recently acquired a free treadmill and tore it apart for the motor and other parts. I've since used the PMDC motor and its controls to power an old (1940s) Craftsman drill press that I restored. Your videos have made clear everything that I was sort of guessing at as I rewired all the parts.
Fantastic ratio of explanation:demonstration. Love the lessons!
The way you explain things is awesome......Superrrrr
I just completed all the video's in this series and i feel like i wasted 1 year of my engineering in understanding this.. you are genius..
Superb articulate presentation, exceptionally well explained Jeremy, thank you!
This was super informational and also easy to follow. Thank you so much for helping me get through my homework!
You sound young and very educated on motor's and electrical you got a bright future ahead of you good job keep videos coming I'm 55 and learning a lot from you thank you
Wow, I have watched count-less motor instruction videos. Nothing comes close to this!! Keep up the awesome work
Jeremy, just found your channel after watching Destin's Smart Every Day channel two. Whoa
. Never ever knew what the capacitor was for on a motor. Brilliant explanation. Wish I could shake your hand. Thank you very much.
Great video's. I have watched many different ones. I like how you demonstrate also what you talk about. I am the guy who can watch someone lecture on a board and struggle to imagine it in a real setting. You show your drawing, and then in a real setting, this is perfect for me. Super job, just had to let you know.
I love the simple and practical way you explain stuff.
great explanation and clear video. I'm gonna be back many times! Highly recommended.
You are a fantastic teacher....THANK YOU SO MUCH....CAN'T BELIEVE HOW MUCH I HAVE LEARNED
