Well, it's blue diode that took most time and effort to develop and overall brought us into the modern LED world, but with such logic you can't say that was a real invention since there were already red and green ones
Move from knurled to toothed so you can have gear reduction. There's enough diameter change available to get a considerable torque multiplication. The added mass and frictional losses will hurt performance of course but there's always tradeoffs. Alternatively, 4 motors could be placed centrally with a reduction belt drive to radially placed rotors. Though, you might find it difficult to minimize PCB flex due to the required belt tension.
I remember back in 2000 a buddy designed a highly controllable micron scale oscillator . He was seriously thinking about a vibrating toothbrush as his first product when someone mentioned that fiber optic wires were really hard to align. That idea alone took the project in a completely different direction.
Could also work as a control moment gyro. Even if the torque is low, over time it'll be able to spin up a decent mass to high speeds. Then you could use a higher power servo to rotate the entire PCB
@VEC7ORlt I'd argue having both would be useful. You could use the reaction wheels or CMGs for quick large movements, and use the magnetorquer to desaturate.
Awesome work! These motors would be good for low profile gyroscopic drone controls or a micro flywheel battery. Or even make them water proof and use them in micro submersible ROVs, with no brushes and ease of water proofing they would be ideal.
for the aluminum rotors, if you have the ability to put the finish you need back on the surface (anodizing it or whatever), you could intentionally order rotors with a smaller inner diameter than you want and then just finish it up to a really tight tolerance yourself, and then you could have more flexibility in what manufacturers you can use
thats not expensive atall ...im a starving artist and i could even get some at that price...also the inbeded driver is a godsend to me ...i cant code so making it as simple as possible is so nice
+/- 0.05 is crazy for a press for like that on a bearing with radial clearances in the microns. There is no reason you can't get +/-0.01 on a 5mm bore economically. I also don't see why your other dimensions are so tightly toleranced, that's potentially adding unnecessary cost.
Have you considered/tried switched reluctance or synchronos reluctance designs to avoid the need for the magnets and that assembly step? Also, you can buy SMD solderable threaded bosses which you could have pre-assembled on to the PCB in the assembly stage, removing the need for the nylock nut and reducing the depth of the motor. You may need a small bit of threadlock to prevent it from coming loose, but you could also by pre-thread lock applied screws. 3 mounting points should also give the same stability as 4 (but 4 may be easier with rotational/mirror symmetry). Have you also considered using one of the standard connectors like JST with the sparkfun QWIIC which would make it even easier to integrate into projects?
Hey bro, I been watching your journey for a couple of years. Some thoughts, have you tried sapphire jewel bearings, like those used in watches? The other thing is the coil wires, have you tried designing the coils non-linear like zig-zag or small arcs? Would that give a different result in the EM field?
Noise and temperature measurement in the testing chamber would be an interesting way to monitor hearing aging. Did you record RPM feedback to see if it decreased any?
the once i should weren't locknuts, so the bolted shaft might get loose over time with the vibrations of the motor (we experienced this with a standard nut)
How could AI have made this project faster to market? We need virtual environments that mimic the real world so you can build everything virtually except the final build.
Good to see actual inventors at work, hope your project will be used in many awesome real-world applications, it deserves recognition
'inventors' I hate this word with passion.
This is not an invention, just a garden variety BLDC motor with an unusual winding.
Well, it's blue diode that took most time and effort to develop and overall brought us into the modern LED world, but with such logic you can't say that was a real invention since there were already red and green ones
You do never stop to amaze us, Carl! We just can't thank you enough for your support throughout the years❤! Happy Holiday🎄🎄🎄
Well done! I was wondering when we would see this. Totally worth the wait.
Thanks! It was really hard to summarise everything into one enjoyable video but I'm happy with how it turned out!
Amazing work, Thanks for showing some of the R&D details. It showcases the rigor of creating a good product.
Love to see this done. Amazing work!
"I decided to study PCB stators on my honeymoon" 😂😅

Hope to see the drone soon!
Have you thought of using it to drive a flywheel for Cube Sats.
good idea.

Why do you even need flywheels for - just use a magnetorquer.

That tiny motor is super underrated! :D
I love this project. I think its fun and engaging. Looking forward to a 35mm drone in the future!
Have you considered using the pcb motor with a built in cycloid gear to get more torque?
i have but still not sure if its feasible
Incredible work! I would love to see a tiny self balancing demo. Seem like they would make good gyroscopes
Can't you install 3 miniature hall sensors directly behind coils and go for FOC ? No more problems at start-up then

It's crazy how tiny changes can make the difference between useless and useful

Self stabilising flight? Use them for gyro stabilisation for a cube sat?
Great work! It must have been very frustrating at times
It was but I am proud with the end results 🙂

A PCB drone would be so cool, super excited to see if you get one to work!
crazy project and the results are even better i dont think the motor is expensive its cheap well done
You do great work, thank you.

That's epic man! Congratulations! I've been following your work on pcb actuators since you started, so wonderful to see what you've acheived
thats just extraordinary bro !!!! keep it up , this even encourages me!!

now we need to get one of these sent tomakers muse for a minute combat robot
I know nothing about this stuff, but could something like air bearings be used?
High respect for passion and sustainability in pursuit of perfect result 💪
9:23 memento mori
Congratulations and HML. Make a lot of smart babies like you.
Already ordered 2
Halbach array those magnet for better torque
Been following for a long time. Congratulations 🎉
The gravity point is center for flyings. A jet wings on high golden meltings. One time only please.
place a magnetic encoder and try to drive it with FOC
This motor could be the indicated for a cyclocopter's cycloidal rotors
Make it smaller, and make it a radial fan. I could use that.
What about making gyro thrusters (or how they correctly called) for a pico satellites?
I wonder if it has enough torque to work as a reaction wheel.
Bearing are to be used in pairs, single bearing cannot properly support anything.
Yay new vid!
Amazing!!!!!!
What about magnetic bearings?
I love your accent, mate
YES!
You could have used a soldered pcb standoff instead of your lock nut. There some around with a hight of only 2.5mm
the once i should weren't locknuts, so the bolted shaft might get loose over time with the vibrations of the motor (we experienced this with a standard nut)
@@CarlBugeja There where are some glues for locking screws into place maybe that could have solved your problem.
Learning I started to learn pcb stators on honeymoon!!! Bro is too much dedicated 😅
To be honest 12/14€ is great cost
Cool
nice
(equal to 3 months non stop at 12000 rpm)
make it into a tiny tesla turbine!!
This has great potential in robots but can we get this in bigger size o diameter like 10 or something
If I could afford it I'd give you every dime i have...
Why you throw away bad rotors, just use reamer instead
👍
✋
i didnt even need to watch the video to know that *one point six billion* RPM is physically impossible. That would melt the metal instantly. Clickbait
Откажись от подшипников
Its pretty cheap for the specs.
Please turn off youtubes experimental ai translation stuff... its annoying and wrong.
i like your company etc... but what an idiot gives spins per day when all the word use RPM even USA that use imperials...
I honestly think that’s underpriced. Great product, now to find a problem for this solution 😈

I rather study positions on honey moon
