Good to see actual inventors at work, hope your project will be used in many awesome real-world applications, it deserves recognition

[BlenderGuy]

When you showed the price I said, out loud, "Holy shit that's cheap". I can't believe you got the price that low for such a small scale product. You are doing amazing work!

Your aluminium rotors are black which means they are anodized. Anodization make surface spongy and make dimensions little bit bigger. Final dimension is unstable after anodization. Not only every batch, but every run in anodizing bath gives you another results. It expands aluminium because raw aluminium is converted in new chemical compound. If you want exact tolarance, you should make hole smaller, anodize part and resurface critical dimension up to desired tolerance. You really need dynamic balancing after completing rotors.

You do never stop to amaze us, Carl! We just can't thank you enough for your support throughout the years❤! Happy Holiday🎄🎄🎄

That is the greatest PCBWay ad i ever seen. the amount of designs you pump out is truly incredible.

[MarinusMakesStuff]

Did you ever look at Hard Disk Drive motor bushings? These also do not use a locknut as the magnetic field keeps it in place. Bushings are probably even better than bearings in this case.

I think this could be very useful for integrating small fans onto existing PCB designs. Place it right next to your heatsink or hot parts. Just need a good "fan rotor" now.

[colbyjohnson]

Well done! I was wondering when we would see this. Totally worth the wait.

[graxxor]

This is peak YouTube! Showing young inventors and engineers creating the future right in front of our eyes.

I’m currently working on ESP32 based platforms so will look into purchasing a few of your motors to have a play with!

[joerideman]

Awesome and inspiring! Motors are sold out so here is a little something for your efforts.

[enescankayhan]

It made me feel weird and kinda proud of seeing a research paper written by people from my country. Cheers to Middle East Technical University, Furkan Tokgöz, Gökhan Çakal and Ozan Keysan 🍻🍻

Amazing work, Thanks for showing some of the R&D details. It showcases the rigor of creating a good product.

That light motor would be great with a light propeller, on a paper airplane. Use a small CAP for power, charge with USB. Kids would have a blast in class with those. Would be a good STEM experience for kids.

Throughout the video I was asking myself "what is the advantage of a PCB here?". I figured that integrating the motor with the rest of a project (on a single board) could be a huge advantage in certain cases. So thank you for making the design files available!

Btw, did you know about the Open Source Hardware directory which the OSHWA runs?

[han_pritcher]

It's an interesting idea. The Panasonic Twin Rotor Motor was a very slim motor, only a few millimetres in thickness, in compact cassette players made by Panasonic in the 90s, that had very similar looking PCB-based coils on them. While there isn't much information on them anymore, they appeared to operate in a similar way to yours.

[fagear]

11:55 not really "new". I have a cassette player from 2001 which motor has its coils printed onto PCB. It was done in mass production ~20 years ago.

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.
