I'm currently 14 years old and because I am interested in electronics i have build this with help of my older brother and my father, and now it is finished and it worked out very well, thanks.
Brilliant video, thank you! The only thing I didn’t get at first was how the commutator facilitated the rotation... but I got it. The break in the commutator means the direction of current flow through the coil is continuously flipping, so consequently the magnetic field in the rotor is also flipping, as per fleming’s hand rule.
Whether using standard iron cores or exploring cutting-edge 3D printing methods, the principles of electromagnetism remain central to motor design. This blend of foundational knowledge with modern technological advances highlights the continuous evolution in engineering practices, offering both practical insights and a glimpse into future possibilities.
Very good description of how an electric motor works. When referring to a rotor and a stator a person is talking about an alternator or an a/c motor. Commutators or used on a dc style armature . The motor that you have built is a typical permanent magnet dc type of motor or dc generator ,if a rotating force is applied to the shaft such as wind, water wheel ,human or an external motor or an engine it would work as a dc generator .A rotor utilizes two or more slip rings depending on if it is an a/c motor or an a/c alternator which can be single phase or more. dc motors have field coils and an armature a/c motors have a rotor and a stator winding. Thanks for the video
Wow Sir your 3D printed motor looks amazing as well as you graphics? Your such a wonderful benevolent individual for giving away your design to 3D print this, if only more people were like you 😇
I made this. 3d printed most parts. Only managed 240 turns. But I made slip rings and made a A/C generator that managed to light an LED. The pulses were clearly visible on the video as I used a cordless drill to drive the shaft. Definitely going to modify the rotor to add a second set of windings at 90 degrees. And a second set of magnets. Maybe scale it up to use larger wire diameter. Or maybe make a transformer to step it up.
I built this last week. I'm in my first semester of an EET associates and doing this was extremely satisfying and made me even more excited to learn more
This was actually a project of mine that I did in my engineering design class (like 3.5 years ago). I took that class to see whether or not engineering was for me. My group was 1 of 3 groups (out of 10) that got ours to work. We also collected data on the amount or work produced 😄. Fun project and our professor was very adamant about keeping the help he gave to a minimum.
@@UltraGamma25 I feel like if a teacher provides all the necessary information, in this case things like lorentz force interactions, torque, etc., then allowing the students to apply these concepts themselves rather than giving them an instructions guide would let them develop and strengthen their thinking and understanding of the subject
For hobbyists and enthusiasts looking to explore more advanced materials, metal 3D printing presents an exciting frontier. This technology, which involves using metal powder and sintering it with lasers, allows for the creation of complex and precise motor components. While this method is costly and typically requires external services for production, it opens up new possibilities for custom and intricate designs that were previously unattainable with traditional manufacturing techniques. It’s a fascinating example of how modern technology intersects with traditional engineering.
Hello Paul, Thanks for the informative video. I just have a silly doubt regards to an alternator. When a coil is rotating in a magnetic field, will it be rotating at a reduced RPM or at the same RPM, compared to the same coil rotating with no magnetic field at the same power. Does the Lenz law affect the speed of a rotating coil in a magnetic field? Kindly enlighten me.
This is not my field so please excuse if I sound out of my league. My thought is, the way the comutator is positioned, isn't the field and armature magnetism wanting to fight itself as it passes through the strongest part of attraction. I would think some power is lost because it needs momentum to push past instead of the field changing right before or at the strongest attraction. Again, I may be way off base, and I know this is just a demo for explanation. Love the videos. Sorry, answered my own question. Permanent magnets have fixed north, south. I had in my head an electromagnetic field, thus each field each having a north and south. Thanks.
Thank you for sharing this amazing video, This is how Great Teachers develop their Nations, elsewhere in most countries people go to schools and die poor with useless theories.
If you set up your armature in a lathe and took a very light cut across the commutator until it all cleaned up you would have less arcing and also use flat contacts instead of round, with more surface area touching the comm it will provide less arcing also. Cheers.
Do you have any idea how one could calculate the period time without like meassuring any rotation speeds or anything. But more like calculating the magnetic field strength and connecting the magnetic force to circular motion, by of course meassuring provided voltage and ressistance in the copper wite etc. Please reach out, it would be much appreciated since I am working on this as my final highschool project.
Could you also do the live calculation of current using the formulas? For example, you read 52 Ohms after turning wires around the rotator. So, how would affect the drawn current? Or, what would happen if you add 2 sets of magnets on the top and the bottom side of the rotor? I hope I could tell you what I meant. I thank you a lot for showing that.
Thank you so much for explaining the difference between the enameled copper wire and regular copper wire. There's tons of videos on how to make a solenoid and many more on electromagnets that if you replicate the video, all that you get is a short and no magnet. I'm going to order a spool of the enamel and try 🤙🏼🤙🏼
Sorry if I missed it, but is there any particular reason the rotor is shaped like that? I feel like you could reduce the overall size of the motor by just eliminating that giant hole in the middle and moving the magnets inward
The magnets are square so to maximise the field the rotor is square. If it was a curved magnet then we could chnage the shape. But the smaller you make it, the less turns of wire you can fit so the less powerful the motor will be.
So for this toy you built in this video, if I exert a rotating force on the shaft, and you connect the 2 leads to a multimeter, we will be able to see the voltage generated?
Hi, great video, I really appreciate all the explanations, it really helps. But i have a quick question, do the commutator plates have to be made out of copper? Also, instead of drilling a hole into the plates and tying the wire into a knot, I can also just solder the wire onto the plates right? Many thanks in advance!
Hi, everybuddy. Just a question, man, premising it's not a polemic one but just for curiosity: Wouldn't be better to increase the commutator gaps to make engine work more efficiently? WARNING: I'm not competent in electricity. Many thanks in advance.
Brother can you teach us about servo motor or rover mechanism in next video. Your electronic content help us to learn lot in the field of engineering. Your lecture is esay to understand a lot about electronics.❤️
suggestion: construct the DC-motor as bldc, use airbearings or magnetic bearings... Use transistor with infrared IR reciver/sensor combined with flywheel with holes(working as a beam-cutter) to call for remagnitation and feedback if you like. Adjust speed with voltage
I have an issue where when the brushes are touching the space between the two commutators that the motor does not self start. Is there a way to fix this?
Would It be incorrect to assume that if one increased the amount of stators the motor would be more powerful or is something more required to increase the power?
To avoid spark generally carbon brushes are used at commutator. So here same type carbon material can be used between both side of connecting wires and commutator..
Hello, I am trying to make an DC electric motor like you. But my problem is that I would have to use batteries, because those power supply devices are pretty expensive. So is the neodymium magnet. How would I know what battery I should get and where can I get those 3d printed Stators?
The higher the voltage the faster it'll spin. A 9V should work or multiple 1.5V. 3d print model isn't available anymore but it's easy to make from a matchbox or from scrap plastic/metal/wood
@@EngineeringMindset Can I buy that from somewhere? And the white that you use as a coil. Can I buy that from somewhere? Also thanks for responding! Otherwise i'll just make it. And the plywooden base does it need that form or can it be whatever I want. And for the shaft, bearings, copper pipe does it matter what one I buy or are most of them the same?
So it took me forever but I finally built this! Unfortunately I can’t get it to spin. :(. Any ideas? Does it matter which way the wire is wound? Is there such a thing as winding TOO MUCH wire?

This must be gold for beginners thank you for doing this
god bless you.days are finding this hand work of my high school project.thanks.
Just studied it in my textbook
Now watching practical
Thanks Paul❤️❤️

I am totally doing this. Only heaven knows my obsession with motors.
same here
Very good teaching aid.
You could use spring loaded concave bushes on the commutator,
also run 3 stators and rotors spaced 120 degrees apart.

That doesn't sound too good.
A teacher is supposed to help their students understand. Not go, "figure it out yourself." Engineering and physics is incredibly complex.

Use small carbon materal or grafite at the contact of commutator
So carbon dont produce spark
Thank you for making this video
It helped me with mine :D
Its like I'm in school but I'm not lol 😂
Glad it helped!
It did
Thank you!
thanks so much. this is one of the most simplest and lucidly explained induction motor build video on youtube. hoping to see ur other videos as well.
It simply explains the working of motor

A new idea came in to my mind. THANKS.
Great booss,,Really nice
Thanks you❤❤
Scroll saw. Sry couldn’t help myself. Nice build though, I definitely learnt something, cheers :)

How do you get a good connection at the commutator with enameled wire?

I used the carbon graphite of 2 carpenter pencils for my homemade brushed DC motor.
You could probably add some carbon graphite brushes at the ends of your commutator arms to reduce the sparks.
this is a good design. looking forward for a three phase motor or three phase generator project. keep it up.
Awesome project. Thank you.
would it work if only on one site is a magnet. it would be way less efficient, but should work still, doesn't it?

In real dc motor are those wires touching the commutator are the brush?
Use capacitors to reduce arcing on the commutator
