In this project I will have a look at the proto pasta magnetic iron filament and see whether it is possible to create a BLDC Motor with it. Along the way we will learn a bit about BLDC Motors, 3D Printing and finally how to not test motors properly. Let's get started!

Thanks for sharing this video. It's a great dejavu :-) - I've done similar mistakes, when I created my first design. A "traditional" BLDC stator design doesn't work well with non-ferromagnetic material. The copper wires need to be much closer at the magnets. Similar as coreless or ironless designs.
Immediatly thought about you when I saw the title of this video!
Hey! It's the guy!
The genius!
Why have you gone inactive tho? Your videos were so golden, we need more!
your videos are educational and fun. please come back

I discovered this channel recently and absolutely love it because it showcases rather unsuccessful as much as successful attempts which is different from other channels and it teaches more because not everybody tells you what setup works and what doesn't. It also creates an environment of discussion much like the ones found in Universities where students and teachers discuss an idea how it came to be, how it works and doesn't work which is the environment and mindset that allowed hobbyists to thrive in the first place.
I need a couple of days to watch the videos relevant to my work but so far it's great
I love how you show your failed attempts, it makes me feel so much better at my burned up projects. Great job BTW..
I love how you give proper credit. That is the spirit.
Keep up the good job!
Failure is a way to success (said by me, the man that fails 9/10 projects).
I am more likely almost a total failure, I had out of say 2000 project, pass rate is likely to make money possible 20, think that is not bad at all. So I say 99/100
@@cheetahkid you should be glad with even 99/100 projects... I cancel most of mine halfway through because I lack the motivation to finish it.
I built a signal amplifier after designing and testing it different stages in one month it failed or better say burn out in final day of submission
@@hamzamehmood1976 I'd still hand it in. Learning about what went wrong is a more valuable lesson than finishing a product (in my opinion it is at least).
@@jrigvd7291 yeah right
I was just looking at videos on that filament and in 2 minutes you post this. Worth it being subscribed
frickin' awesome! Even a fail is progress!
Your videos are amazing, thanks for the job
What was the infill, if you could increase the density you might have better luck
bout like jlc pcb charging 25$ for shipping. even a fail is a progress when youtubers are involved apparently.
the best part of science and engineering finding ways to improve
haha, forget a counterweight for the whole wooden structure
You are a great educator! Thank you for your wonderful videos. I always learn from them. Keep pumping out content. The Internet needs you!
I love this, even though you way over complicated the testing for the torque, it was an awesome build.
I really appreciate your video because in science, most are only focused on success but there are a million failures that come in experimenting. Failure is valuable data and shows just how hard the see e things can be. Please keep up the great work. I always learn something new from your videos
Excellent video. I try never to underestimate the value of negative data.
My failures have always taught me more than my successes.
Well done!
Fantastic work, dude!!! 😮
It's pretty awesome they worked at all!!!
I love you don't shy away from your failures
You will reach 1 million subscribers by the end of this year. Your videos are so clean & helpful!
Scott shows the way to innovate!
Of course I enjoyed the video. GreatScott is also very entertaining and has a great ingenuity ! Cary on and make a motor that rocks !!
I've tried 3D printed parts for many different high heat applications. PLA always gets soggy, and ABS works somewhat better, but still gets soggy. My guess is if you really wanted to do that right, you could use Nylon, because it has a higher melt and (I think) glass transition temp.
I always wanted to try this, this is seriously really cool!
I love that u did that... i never got the time for that and so wanted to do it... and u answered a lot of my questions.... thx man
Too often people hide their failures and only publish findings if considered satisfactory. Thank you for showcasing your failures and detailing problems you had with your experiment for all of us to learn from.
This is amazing! Thank you so much for posting!
Thanks for sharing your failures with us. I didn't think this was going to work but it was still fun to watch.
Really different kind of video.
*I like it!*
Your experiment was not a failure. I'm sure not only you, but all of us watching your channel, learned a lot from it.
Nice video! I definitely learned something! One learns the most when failing! Keep up the good work!
Nice videos 👍🏻
Great video as always man! Have a happy holiday!
Thanks, you too.
Really great video. I was thinking about pursuing something similar. This gives me a good place to start.
Excellent video. Any experiment that gives a result generates new knowledge, even if that knowledge is how not to do something.
This was not a fail. It was an opportunity to learn. Thumbs up for posting.
Good luck with you subs sir, you're about to reach 1M subs. Congrats 😉
Thanks alot for all the vast knowledge.
Great Vid. Would like to see a follow up where you 3D print the thin laminations with the iron protopasta and stack them (maybe make a hole or holes in each laminate and use a non-ferrous pin or pins to keep them aligned). My other thought would be to laser cut your laminations. The cool thing about these trials is that with a little ingenuity you can use 3D printed parts in a lot of situations.
Great Project! love your videos, thank you!/i have subscribed.
Fantastic experiment! 👏
Keep going with this project it’s amazing
Thanks
Very Excellent project 👍
My Finger Automatically taps the video after reading Great Scott written under.
Good....good....
Same lol
@Mr hahaha nice one 😂
Magic. Keep up the good work.
First of all thanks for the great video, you're awesome. By the way I think that the reason is the air gaps that result from the 3D printing and the magnetic properties of the PLA mateiral. To illustrate, power transformers have laminated steel sheets but virtually no air gaps, thereby reducing eddy or leakage currents and increasing the magnetic properties. However, future and other hi-tech 3D printing technologies are reducing these air gaps, so the idea is very valid!
Great scott is one my anothr best channel
Very informative ,Thank you 👍👍👍👍
What’s funny is that video you kept mentioning I had already seen it and loved it lol
Nice! You should try PCB Motors 😉 brushless motor esc are usually designed to cater for specific motor parameters. Given that the torque of your motor changed it is probably failing the open-loop startup algorithm of the esc
Pure awesomeness!
I made a laminated iron rotor from zinc coated iron sheets. You can "stamp" (saw) them out stack them up and then soft solder them together. After some filing and balancing it worked really good. BUT you need to have the patience. I had tow saw 50 pates with a jigsaw. It's important to clean them up and press them together before soldering.
Great is great... really watching your videos is an inspiration for the hobbysts.. thank u Great.. :)
Yoiur videos are amazing! Thank you!
Awesome as usual.
Learned more from your channel than I did through my entire school years
1Million subs soon !!!!!!! Be ready dear Great Scott
Excellent video. Thanks.
Good afternoon, another simple way to measure power of the motors, would be connecting in a motor generator, congratulations for the excellent video.
Using normal 0.2mm steel sheets ("Billiges Gießkannenblech") works totally fine for building motors. The efficiency will not be super high end, but it will be fine. They do need to be coated with insulating laquer though.
How do you turn them around?
@@yosyp5905 What do you mean turn them around?
That idea would certainly be worth a new experiment.
@@yosyp5905 There's no need to turn them around. Get the sheets cut in bulk (laser cutting works fine here), lacquer them, and stack. You have your stator right there, ready for winding.
There's no problem in printing the central core of the stator.
I love this videos about BLDC motors!
I think the reason why 3D printed motors had so high RPM in no load operation in comparision with regular motor is because every DC motor wants to spin with RPM so high, that voltage induced on armature is equal to supply voltage (with opposite polarity, so armature current is close to zero in no load operation) . In regular motor almost all magnetic flux from permanent magnets is flowing through core of coils, so according to Faraday´s law (Ui=-N*d phi/dt), the induced voltage is high enough even at small RPM. In 3D printed motor, the core of coils has very poor magnetic conductivity (even magnetic filament, it has relative permeability not much higher than 1), so only small part of permanent magnet flux is flowing through coil cores (the rest of flux is flowing through surrounding air), so the RPM needed for Ui=-N*d phi/dt to be equal to supply voltage is much higher. The results would be much better, if the core was made from epoxy resin mixed with high amount of iron dust, that would be awesome video by the way :)
Now the question is how to cast the epoxy with high precision:)) nice idea btw
@@revimfadli4666 casting the epoxy would only require 3-D printing the shape you want, putting that in a cup and pouring in two-part mold making silicone, cutting the silicone negative in half and then pouring in the epoxy and iron dust mixture and letting it cure. Not that hard.
@@artbyrobot1 Remember to do that under vacuum and to vibrate the mold, otherwise you will get air inclusions in the cast part.
What about putting an iron nail through each of the fins?
So informative. Thanks so much.
I am hearing about the feromagnetic filament for the first time and I'm excited! Ok what I'll write is just my naive optimism, but we got conductive filament and ferromagnetic, what 'bout stick them both into multimaterial 3D printer and try to print stator right away! :D I know conductive filament has too high resistance and ferromagnetic one is not a good ferromagnet. But hell yeah completely 3D printed motors sounds like a kinda thing we need to pull off completely 3D printed machines!
Will you be making videos on the electric scooter build? I had this indea a few years back, but my electrical skills and knowledge is holding me back, so I'd love to see you do it! Also, I don't understand half the things in your videos, but I enjoy watching anyway, haha.
Seems it might be a synchronization problem. That might be possible to remedy by simply introducing a flywheel. More rotational mass. Would be very interesting to see what sort of efficiency you could get out of your stators if you can manage to get your controllers to actually, well, control the motors. I hope there is a part 2 in the future.
Great work
This is a cool thing to print. It makes 3d printed machines cooler and cheaper.
Great video!!!
Great Scott!
Oh man, I rewind polyphase AC stators for a living, I was grimacing when you melted that first 3D printed core, lol.
This could be the beginning of the revolution. :-)
Random UA-camr:

Watch dogs 2:
>3D Printing ready to use guns and drons
3d printing single shot guns works, and using slm you can probably make a decent gun and even make the ammo.
Drones are more complicated since you need to print the circuit board, but with a pick and place and a router, that's also doable, and the motors are still the hardest part.
@@satibel r/woooosh
@@jakeyyyyyyyy beware of useful information, you might learn something new
You will definitely need neodymium iron boron magnets instead of ferrite magnets if you hope to have usable torque. You might be able to 3d the stator hollow and fill it with iron filings to improve the permeability of your core.
love his videos
Great video. Glad you shared even though the results weren't all ideal.
Getting into exactly why something fails is always useful - and is there a way to stay on the right side of the fail factors. Do you plan to follow up on this at all?
For example, if we cannot achieve useful power densities using (PLA FDM) 3D printed parts, can we change the format of the motor?
dude what a coincidence I was watching the 3d printed video this morning !
you make my day bro
Interesting video!!!
You are amazing!!!! glad to be a Patreon Supporter!!!! You are the best! I've been wanting to find a way to make my own motor in a practical and economic way. Could it be possible to make a transformer with the same method?
Thanks for allowing us to learn from your mistakes :)
5:14 : what is a Macrenwiiii???
Just kidding, I raised an eyebrow for two seconds before seeing it written down µH.
Its magrenry
You live and learn Scotty!
to calculate the efficiency (or say power) you can directly use formula....... because you have all the parameters.....RPM and torque. it is enough for calculating efficiency.
check torque RPM and power relationship
In order to increase the magnetic flux you'll have to add material with a high magnetic permeance , even magnetic materials like my n52 magnets have very less permeance of over 1.5 , whereas pure iron has over 200,000 and silicon steel or the electrical steel alloy used for motor construction has over 20,000 . These figures are available in Wikipedia .
All in all an awesome attempt to make the motor , I too am trying to build a motor . thanks for sharing . : )
GreatScott, you should set up a 3d printer with duel heads so that you can print a layer of the magnetic filament and then a layer of abs, over and over. The one in the video allows eddy currents to form, decreasing efficiency.
great as ever !! :)
I'm sure it's been said but you'd be da MVP of any crew in a post apocolyptic scenario. And very interesting project as usual
Maybe the motor didn't reach self-synchronism in your set up and didn't start up because the inductance values of the phases were too low and the esc could not maintain synchronism. As a matter of fact the normal BLDC motor started properly while the other two didn't want to start. This is not true, of course, in case there is no load attached to the motor, like you showed previously in the video. Let me know if you think this is a possible interpretation of the problem. Great work as always.
Yes, the prop's momentum was too much for take off. Those ESC's are blind and can only see position through back EMF, so they can only guess what to do during take off. That was a massive prop, and since he was clocking in some 3000 kV with the new motors, he should be using like a 6 inch prop made out of something light, like plastic. That same motor in a 3000 kV configuration would probably do the same as he showed (I've made this mistake before too, I tried to put a massive 13 inch carbon prop on to a 2204 2300 kV junk motor just to see if it could slowly spin it, and well... Its not the first motor I've set fire to, and it won't be my last, haha!
Yeah, it's start up, where accelerating the mass of the propellor presents a significant load. Once spinning, the load is aerodynamic and little to do with the mass of the propellor. As a follow up he might consider printing a centrifugal clutch. The input to that will spin with a feeble motor, it can't stall. The output torque is a measure of the best the motor can do.
I suppose, if the inductance is lower, the motor is defluxed, so it spins faster but it has lower torque.
And the torque is not enough to start the motor spinning with a load.
very interesting, thanks
Thanks for sharing your failure! It's easy to assume that things are easy when you don't see the failures that looked like they should have worked!
cool video !
Steel motor cores are built with many insulated layers to increase eddy currents (which I think would show up as higher inductance). Maybe adding multiple insulated layers to the ferromagnetic filament would increase the torque and decrease the k/v rating
See you next time Scott!
Nice try!
I tried something similar as your wood experiment, making a zeppelin with Helium and 2 helix, the decisive point was to know how much force the helix can do. For that i used a bascule weighing all the machine with the helix motor turned off, and then turned on, for sure, before using any helium. In my case all the machine was 110 g with the motor turned off, 100g turned on in positive direction, and 118g in negative current.
Thanks for your videos! :)
OK, printing motors in plastic is not working out.
*How about printing slow speed fans ?*
Please make more videos for brushless motor I liked this video
i bet greatscott(!) will end up to become a carpenter .
I really need to take your example and be brave enough to post fails, I've had about three in the last two weeks and haven't released a single video because of it!
Would printing the stator with "slots" in the cores be possible? In the slots you could glue in steel, and possibly help up the inductance.
Lassi Kinnunen god I love living in the future
if you use solid steel rods, refer to 0:50 to see why it's not a good idea.
unless you use the same technique of "laminating" the steel.
@Lassi Kinnunen The very most practical thing would be to 3d print a design and then make a reusable mold of it with silicon or something. From there you can make wax positives to make metal casts with.
The experiment wasn’t a failure the expectations of your hypothesis were high but you leaned something so in the end a successful experiment.
Gutes Video wir immer👌👍 Weiter so!
1:20 was a literal ' GREAT SCOTT! ' moment :) iron pla
U can use stator from motorcycle dynamo which are made quite well ....u need to find correct size one you have to do some research after finding it you can rewind it according to your project...
1 million, here we come!!!
You can dismount a big trsnsformer and cnc the plates for your motor (aka a lot of work)
you could use those plasma cutter tables that cut custom pieces of metal of any thickness you want. i've seen them on the hacksmith and collinfurze
