Making a PCB Motor spin 30,000 RPM FASTER

[@kingpanguan]

This gets more impressive every video, i still find it amazing that a motor can be this flat, imagine the possibilities for phone and laptop cooling

[@Infinatummedia]

Especially if he uses a tiny toroidal fan. It should decrease sound and weigh less while giving roughly the same amount of thrust

I really appreciate your commitment to iterating on this design. Most youtubers tend to stop at proof of concept and move on to the next thing that will generate views, but you truly seem to do it for the knowledge and it shows. Thank you for helping push the world forward

[@critical_always]

Good on you for pointing it out. This guy is certainly not afraid to try things and learn. I appreciate that a lot.

[@harleyme3163]

or a proper engineer would just replace the motor will one designed to go 30000 rpm faster.... therefor not burning the motor because it wasnt designed to go that fast ( beariing fail, locks motor, board overheats, boom meltdown... I find these east indian accents ALL scams, havent seen one honest idead from them.... hence I inform others.

Is he a PhD in organic chemistry and materials science? Nano bots will theoretically have to be organic in nature and derived from repurposing a harmless virus by doing some type of rna programming. Ai isn't as far along as the population thinks either. Fpgas will have a bigger impact than agi.

[@nevernether3368]

@@jstro-hobbytech then how about microbots instead? Instead of being in the body it exists on its own in a swarm and when programmed takes on various shapes as a swarm. Like the ones from the big hero 6 movie a few years ago?

[@DrTimmay]

Love the description of the iterative development of your projects. Many, many others only describe the final working version of their respective designs. I learn as much -probably more!- from errors/missteps of others; they made the mistakes so we don't have to. And as always, I appreciate the chapter markers! I know it takes some time to set up and they aren't strictly necessary, So just wanted to let you know that we appreciate them! 👍

[@tyronejk]

Super cool! Your 5 g lift measurement is fairly conservative too, as that fan you tested looks very simple and not optimized for this application.

[@thirtythreeeyes8624]

He was also measuring wrong to get an accurate measure of thrust the motor needs to be mounted to the load cell and measure the thrust pushing against the motor and ya that fan is not anywhere near what you'd want to use for a propeller, it needs longer and less blades and less pitch.

[@rafa_br34]

I can't wait to see how successive the subsequent iterations will be. Great job!

[@AtlasReburdened]

Isn't every iteration of anything 100% successive?

[@rafa_br34]

@@AtlasReburdened I guess it depends on what the definition of "successive" would mean for said iteration. I said "successive" as a positively biased way to measure how good(resilience, torque, speed, etc) the next motors will be. From my understanding in the context of logic/code, an iteration isn't always successful, however, it will most likely provide a starting point for the next iteration, and in this case, it will be the knowledge required for a better motor. Anyways forgive me for any typos/mistakes as English is not my native language and it's 4am for me.

[@Maleko48]

I love everything about this video and your concept, EXCEPT the part where you are staring at an object rotating 30k rpms on its radial axis with no safety glasses or face shield, etc. Stay safe my friend. I hope none of your experiments ever "let go" and bring you harm. We need more people like you!

[@supercopter2309]

i started watching your videos when you where trying to make some jumping flexible pcbs or something like that. i tjought "this guy does not know that much what he's doing" but it was still fun to watch. now i see your motivation has led you to some really interesting outcomes. so many iterations, and so much effort, it ends up paying back. thanks for sharing!

[@dehCremus]

As an Embedded Software Engineer working on a motorcontroller for the E-bike business, I find it really impressive what you managed to get working using the sensorless algorithm. TI has a lot of info on sensorless FOC control using their FAST estimator. Definitely worth looking into! Cheers

[@pratyushkar8426]

You have put a lot of work into this buddy.... kudos for your success and keep working hard we love it!!

[@jameslmorehead]

I think you could get more out of your motor by modifying the coils to a fractal design, or stitch them to inner/bottom layers for greater field strength. This is an awesome project. I wish I had your lab and sponsorship to get this done. I do work for a motor R&D firm, so I'm not sure how far I could take it without it being an issue with my job. However, if you have EM and/or back EMI questions, I'd be happy to pass them to our science team. We have some of the best magnetic motor designers in the US. Matter of fact, one just got back as a keynote speaker for an automotive EV trade show, and another is currently a presenter at another specifically for motor EM design.

[@ohbeardedone9253]

Can this compete for power to weight ratio of current drone motors?

[@jameslmorehead]

@ohbeardedone9253 It probably could be for micro drones if it were modified. You would need the rotor to be on both sides of the PCB and get the electronics in order.

[@jameslmorehead]

So, after some digging and research, I've found this small single IC to drive the BLDC motor is very old school tech. I'm wondering if a manufacturer could pick it up and revamp it with a SiCFET output stage. Adding SiCFET discrete FETs might just add bulk. It would be interesting to see what is available, or if a manufacturer would be willing to do a flip chip and wire bond assembly to the PCB on a prototype scale. Running EM sims on the coil stacks, I have found much better configurations than this racetrack approach. While it does work, the magnetic field shape does not interface very well with the PMs in the rotor. I think an increase of 40 to 60 percent in power can be achieved with a coil redesign. I've found a practical use for this in the ant weight class of combat robots. I do have another couple tricks up my sleeve, but I want to see if they are public domain, owned by someone, or something I could patent. This would increase low speed torque and increase maximum top RPM.

[@adubs.]

When I worked at Nidec Motor Corp in their ECM blower motor division, one of the projects we spent a lot of time on was closed loop motor drives using only a single shunt for feedback. You had to play games with the timing to read individual coil states. Definitely a head scratcher.. but it worked.

[@hdheuejhzbsnnaj]

This stuff is really so fantastic. I'm just waiting for you to go through another 5 years of this prototyping and then I'll hop on and use these like it's no big deal. Easy! 😉

[@microbuilder]

That super lightweight brushless ESC would be PERFECT for the micro RC plane hobby...theres a few micro ESCs out there now, but they're significantly heavier. Really cool project!!

[@chopper3lw]

Your tenacity is amazing. Nice job Carl.

[@MarcStollmeyer]

For drone propellers 2 blades and large diameter helps with efficiency. When you measure the thrust also measure wattage to get the efficiency of the design, and efficiency specifically at the target hover thrust (as thats more important that total thrust).

[@toplist2613]

I want to see the PCB sandwiched between 2 rotors. Or… a rotor between 2 PCB’s… etc.. just seems like such a stackable design. Cheers! Thanks for the content!

[@WeBeGood06]

Great motor development Adding larger holes holes near the axis of rotation, inside the magnets on rotor, or larger via on pcb. A flat disk spinning next to the flat pcb should be a nice fluid pump. With no holes, it would tend to make a vaccum near the axis. Lower pressure, lower conduction, less cooling. Adding fresh air to be pumped out by the flat plate pump should improve cooling. Maybe holes next to the bearing hole rotor, so the bearing is supported by pedals created by the cooling holes instead of pressed into a circular hole.

[@1_HighDuke]

You are a modern sorcerer! Well done!

[@mjodr]

One more thing: It's possible in your ultimate goal of RPM, that certain designs beat out other designs pure because they were balanced better. Turbo charger compressor and turbine wheels are balanced to the Nth degree because of the insane ~100kRPM goals. They mill off parts of the fasteners and such to get it balanced really well. If you aren't making sure your designs are tested with very precisely balanced assemblies you are pissing into the wind. You could measure magnitudes of inefficiencies purely due to a balance error. Keep that in mind.

I was amazed at how low you brought the thermals down. Great work! I've always been fascinated by PCB motors, and thought they would tak over the industry one day. Even with the development of today's insanely capable PWM controllers, it's hard to overcome simple thermodynamics. While it's possible to make small, lightweight motors witn impressive burst power output... their loaded duty cycle leaves much to be desired. I had a dream once, that I'd built a PCBM powered motorcycle, and was ripping my hair out trying to develop a variable transmission for it. What I eventually came up with, was a dual motor input planetary drive, similar to Toyota's hybrid system, but with only one planetary. I was rudely awakened just before I got to straddle the bike for test ride 🤬🤣 Anywho... best wishes to all you tinkerers!

[@mikelarin8037]

2 blade propellers are the most efficient propellers for drone or plane purposes. you could try one of the 30-75mm propellers for micro rc planes and see what they can do. One that would fit your needs would be about the size of the one that the powerup 4.0 rc paper airplane kit uses. Would love to see what you can get out of it thrust wise

[@simonexner6199]

actually not quite true. Most efficant are one bladed Props (eg. in the AFT 19 evo retracting RC-Glider engine) But they are a nightmare to get working: balancing them is extremly diffilcult and they are loud. Very loud. But if you can handle the torque from the asymetric thrust through the motors bearings and want to squeeze every little percent of efficeny out of the setup, go with one-bladed props.

[@kartoffelwaffel]

@@simonexner6199 actually you are both wrong. The most efficient props are 0-bladed props.

Holy moly! Here's the man to make the real high end sensored ESCs opensource and attainable in the RC space! By now they're not only outrageously expensive, but also a wild mismatch of parameters - sensored systems are only existent up to 1/10th of a scale, and all that's higher - is unsensored, which is bonkers! Not only it makes big RC cars require huge 6-12s accumulator banks which add a lot of weight and are quite a pain in the butt to handle around and charge in reasonable time - but the cars themselves tend to be powerless at low speeds, basucally, full send smackers. And that is no good when you want to eeease your 1/5th scale jumbo up that steep climb. And also makes you replace a lot of parts frequently, when you collide with everything on a route, which your gutless bastard can pass only at the full throttle. Go on with your research, and put it's fruits into a real high-end high power beast which would allow big rigs to be a little bit less out-of-hand one day! Cheers!

[@HolmesHobbies]

Nice progress! Thats an awesome chip. Have you considered dual rotors since you dont have backiron for the coils? A second rotor would conduct the flux back, right now your coils are air core and also without back iron. Thats why your rpm drops so much under load.

[@NightVisionOfficial]

Can't wait for the PCB Drone, really cool videos man. I love they way you iterate, and make the PCB smaller and smaller. When i'll get good at electronics, i'll try things out x)

[@filips7158]

Here's a tip you might find useful if you intend to keep using the ADC module on the dsPIC33 devices. The ADC module suffers quite a bit from internal noise and you might read garbage values or be flooded with noise. Software filtering might not cut it either as you'd reduce the bandwith of your measurement signal and waste precious CPU cycles. Solution, right after triggering manual sample, put the CPU to sleep. Also, configure to interrupt and wake up when sample is done. The measurement quality will improve dramatically.

[@cadcaetutorial2039]

This videos is very nice sir

[@chipcode5538]

Very nice I was checking the channel regularly to see if there was any progress. Can you move the coils to the outside of the motor. This will likely increase torque because only the radial parts of the coil cause torque. When the coils are on the outside you can fit more coils also increasing the torque. Minimise the circular part of the coil and maximise the radial parts of the coil. Another thing you may consider is placing an extra rotor on the other side of the coil. You could make a stackable motor design, Rotor - PCB - Rotor - PCB - Rotor, etc.
