TSP #22 - Tutorial and Experiments on Magnetic Levitation
Вставка
- Опубліковано 7 лип 2024
- In this episode Shahriar demonstrates one of the simplest magnetic levitation circuits. First, the basic concept of magnetic levitation is examined. Two different methods of detecting the location of the levitating object is presented and the Hall effect sensor method is chosen. A semi-digital overall system is implemented where a PWM control IC is employed to control the magnetic field strength. The block diagram and functionality of this IC is presented. Finally, the schematic of a dual-Hall effect sensor solution is presented. The circuit is built and tested in both open-loop and close-loop configuration. Magnetic levitation is demonstrated with the capability of adjusting the levitation location. The schematic of circuit can be downloaded from The Signal Path website.

How can I miss this video all these years. Elegant technique. And beautiful way to demonstrate control theory.
Great video thanks for your time and effort it is much appreciated. You are a great teacher! I know you did this years ago but your videos are helping an old fella get his head around electronics today.
This is one of the best tutorials I have ever seen. Thanks. You are a wonderful teacher.
man so cool...your description is so simple to understand. anyone with basic knowledge in electronic can make. you make it that so simple... There is complicated circuits for this but this one is simply the best..
So much positive feedback for negative feedback! The kids of my colleagues at work get a kick out of this each year during Bring Your Kids To Work Day. Thank you Shahriar!
Thanks. Watching your video always gives a high as if I am physically doing it. You clear the possible doubts on the way and is a very effective teacher.
As I have commented many other times, you are a good guy! it is so awesome and inspirational that you are giving back, it makes me want to be a better person... Back in the 90's I did a very similar magnetic levitation project as part of a controls class final project except we needed to do a full blown analog controller, as I recall it was much more complicated than your approach. Thanks again
This is an excellent explanation, easy to understand without being too simple, and detailed enough without being confusing.
What a neat little experiment !
Another excellent video, demonstrating principles very clearly and then a practical demo! Keep up the good work.
Excellent video! Really well explained. You are a great engineer.
Thank you Signal path blog .Another really good video .
Excellent Video!!!
Thank you, I really appreciate the way you take the time to explain the circuit and the build. Not many people do that !
I absolutely love your videos and the way you can explain difficult subjects. im glad you're reaching a milestone in the amount of subscribers, that only means we get to enjoy more quality content. thank your Mr Shahriar.
Thanks my friend.
A wonderful project and a top-notch explanation of the theory behind it!. Your videos are always instructive and entertaining. I really appreciate the effort.
very high quality videos packed with clear explanations....and neat work.
you deserve a high quality thanks.
Thank you very much for your effort for making this very educational video. Your teaching style is innovative, not many people make cool projects and explain them.
Great effort and thank you for such great videos - much appreciated!!!!
this helped explain hall effects pretty well. I'm currently trying to make a diy 500g-1kg (it be great if more) electro magnetic levitator with conventional metal infused PLA filaments with my 3d printer. its a very slow tedious process but im finally making some leeway in my current prototype demo thanks to this video. I need to find a real ferrite outter circle though for the 3d printed electromagnets (used electromagnetic filament for the base of the 4 electro magnets and copper wire wrapped around)Thank you!+thank you to all the commenters putting a lot of other equations here.
Well, there's another one that you hit straight out of the ballpark. Super! Absolutely stupendous! If you're ever in Houston I'd be happy to buy you a beer! Thanks for all of your hard work.
Your videos are so creative and well explained. Who would ever have thought to use levitation as a lead in to understanding PLL's. Genius..........
Thanks
Amazing video, thank you!!
Thank you for the prompt reply.
Excellent! Another great tutorial from you!
I LIKE THE SETUP!!!
Simple and easy
Explanation are great in every single video!!!
Keep up the good work
I am learning a lot thanks to your videos
Bravo! Excellent Electronics Video!
Thanks for that. Your an excellent teacher, keep em coming.
Excellent video.
Thank you.
thanks for you valuable job on teaching guys how to make a circuit that really works. You are so great. I will build it for my self.
Excellent !!, enjoyed the video
Awesome video, you are a big inspiration to me and I can imagine to many others.
Great demonstration!
Neat. Can't wait for the future videos you are talking about.
As usual a very nice video. Thanks
Man i Loveeeeeeeeeeee this channel , thanks for the great explanations and tutorials , please keep up the good work , your fans from London .
The system has feedback, it does not operate in open loop. In fact, it won't work in open loop at all. There is feedback around the error amplifier which goes all way the way through the electro-magnet, Hall-effect sensor before it is fed back to the error amplifier.
Awesome video and awesome teaching thanks!
This is still a great video. Thanks 7 years after the fact.
Nice video on levitation!
Great video as always, well done.
Nice one! Good for teaching
Excellent experiment. Simply put : Food for the brain :).
BTW I know students from the local university that follow your channel with 10x more dedication than all the courses they are having.
Another great video. Instead of KA7500 you can also use TL494, AFAIK they are identical and both can be found in old computer psu, best way to recycle old parts.
You are a very good teacher. Thank you..
Great explanation.Thanks very much!
from Bolivia SudAmerica thank you your videos are amazings!!!!!
I love the two Hall-effect sensor idea, that's genius.
It appears as if you have damaged the two large electrolytic capacitors during your fine-tuning. the tops of them are obviously bulging after too much heat was generated internally.
Many thanks for a super video.
Great Video! Very Informative!
Loved the video.
Great Job Man
Loved the video, brilliant
As always, Excellent. Thanks.
👍👍
Great learning material!
Great show. I sent it to my nephew to enjoy as well.
Fantastic video, as we have come to expect :) Thanks very much.
I will try this analog ciruit it is just GREAT!.....Thanks
Great video. Thanks a lot. Best regards from Victor Micha. Mexico City. 🇲🇽
Realy good job!
This is such an interesting video. Thanks very much!!!
Another great video. Much appreciated.
You are in inspiration to so many - the 5k subscribers you mention at the end of the video is now 30k! Including me. :)
You keep me studying even when I'm trying to take a break!
very well explained. Thanks.
Thank you! great video..
Fantastic video. Very clear & informative. Now know what my next project is going to be
Keep up the good work :)
I love your videos, you're such a good teacher.
I felt that I should tell you that =)
I enjoyed this video!
Great video, really takes the snore out of my controls class and gives more intuition as to what and why i study controls. But if i do build this gadget i'd probably try to make it levitate using a knight rider effect on it. But again thanks for the inspiration and intuition, looking forward to more videos from you.
well done; thank you!!
Very interesting and informative, thanks,
Excellent !!
Thanks.
Thank you!
good one. Nice.
Awesome video keep it up!
Awsome looks sooo simple when u do it.
Hey man, I've just found you yt channel, your videos are awesome, keep teaching us! Thanks!
OH.MY.ALLAH. I've been looking for a way to build an electromagnetic suspension device like this for so many days now! I was scratching my head and piecing together scraps of research but was getting increasingly frustrated - to the point of thinking of giving up.. You have seriously saved my life with this tutorial. Very informative and has everything I need. I'm an instant subscriber! You are helping to inspire and teach countless students young and old all over the world. Thank you.
Jeeeeebus
Good stuff!
Thanks
Legendary!
keep 'em comin!
thanks, very useful video.
Good platform for developing a seismometric sensor.
Great video and very well explained Thanx I really enjoid that
I have to say that this video was absolutely awesome to say the least! To be honest, for some of your other videos, I have stopped watching after 10 minutes or so because they have been way too fast progressing, too complicated with advanced terminology and generally difficult to follow. This video was the complete opposite. Easy to follow and understand, which made it VERY interesting. Thank you.
worth watching Thank a lot
بسیار عالی متشکرم
Don't confess to understand it all but very interesting. Thank you.
You are right. But what I meant is that the IC would work much better, as PWM controller, with some feedback at the error amplifiers. In open loop, with the near infinite gain, the amp works as a comparator and the system runs as bang bang control. The ringing inside the Ton time of the output square wave is the hysteresis loop working at the middle of bandwidth of the feedback loop.
There are of course many ways of doing this. The IC was available and provided an opportunity to introduce a new part people can learn about.
how do v do d same setup with the electromagnet on the table and things levitating over it?
Great !
I am uncertain how well it work with something like that. It all depends on how much the steel ball influences the magnetic field going through the Hall effect sensor at the bottom, and I am not sure if it will have a strong effect on it.
thanks so much !!
You're awesome.
Great video Thank you for all your inspiring ideas. Is it possible to get the schematics of the setup and the list of the parts used? Thanks again.
I really like those probes you have to convert the oscilloscope probes to something you can connect to a bread board ... any idea what they are called and where I might get some?
its great
Really great, sometimes we forget the old fashion way of doing things without microcontrollers.
good vid thanks
Very good nice video
