Really cool project man, would love to see you explore this more. Last year I made an axial flux machine for my master thesis and we used a PCB stator. Very fun to play with and relatively cheap to experiment with once you have a set of rotors. Many different types of winding patterns to try out and we got some very promising results out of it!

After watching videos about axial flux arrangements I configured my pulse motor in this way. WOW, a great improvement over the standard armature. You have built an excellent device, great deal of time and talent.....and money. My stuff would be considered low tech, but it works and one of the motors, so far, is self sustaining, after six months of operation maintaining 8.3 - 9.0 volts on a worn out 12 volt car bat. Will post a vid after the first of the years.

Very impressive use of modern tools to make a functional DIY power dense motor!

man thats got to be my favorite motor ive seen in a while. i generaly love axial flux motors. youve tried to take out every last bit of efficiency of that little thing and that awesoooome. nice work man. love to see it on an e bike btw

Your filming and editing skills are just fine. This motor is fantastic. Sensors are good.

Nice work. I will be following your progression on this. Thanks for sharing. I have also experimented a bit on this subject and will probably continue at some point but... now I understand why motors are so expensive :D

That's pretty cool Colby. That it works is huge! I reckon you need a rig to measure actual power out so you can measure the improvements you make. Keep it up, learning is a wonderful thing. Thanks for sharing this.

i want to see this channel turn into multi-million one. amazing content. keep it up brother.

Its refreshing to see younger generations using their talents. Good job buddy

Thanks it's very inspiring, i love the axial flux motor and i plan to build or buy one for project like ebike for example. Just love searching and testing things like you 🙏

Good video, looking forward to seeing more video for practical application like in small vehicle such as motor bike with both axial flux motor-generator. Thank you for sharing your knowledge and experience.

A very neat arrangement. I'm doing something similar but on a much much bigger scale, where I've found 2 phase to be more efficient on material use. Making a Halbach pattern would reduce this efficiency on materials used but make for fewer stray fields. Keep going and do more videos.

bro the world needs more of you!!!!

You are going to make me build my own motors! Just kidding, but I had the idea on my head for a long time about designing and building electric motors. Great video with great explanations!! Thanks for the inspiration and for the video, Is PURE gold!

Good to see you using back iron. Normal steel works better than cromo for back iron use. Fantastic project motor!

Wow wow wow !!....excellent engineering design...next industrial standard

Beautiful motor/generator! Must/could be very energy efficient. I'm new here, will check your other videos now. Keep on developing/experimenting!

Colby, you have given your idea - much thanks.

This looks perfect for gyro based applications great vid 👌

You’re definitely on the path good job

I really want to design a PCB stator, and this looks like the perfect project to build off of.

I would love to see the generator version. I'm planning to build similar motors/generators for small wind turbines and pumped hydro applications. Subscribed!

Great work, this is exactly what I've been planning/thinking to build for a big r/c car. Seen lots of motors that are similiar but not like this one. The hallbach with rectangle magnets is perfect and the air core windings are simple, and I also want 12v and low rpm for direct drive to the wheels. I may need more torque and thus thicker wires for higher current. I also have other ideas..single phase operation, it is using all the magnets at once, there is no dead third phase. To get direction, use a second winding at a lower diameter, once the motor is moving this second winding is not really even needed.

Awesome video! We're all learning :)

Genius idea Nice set up I like the size

As you could see on startup of the motor, there is an imbalance you should take care of. Balancing the rotor would improve its performance and reduce the vibration.

now they are making radial and axial combined .. raxial ... looks awesome

That is really nice,good job on that,instant subscribe.

The most accessible source of energy to the most number of people on this planet, is low rpm. Personal wind turbines can't reach the height needed for consistent high rpm and most people live along and have access to low head river systems. Good stuff. You folks are doing god's work.

love your work!!!

Beautiful motor! Although machining might be expensive, you might be able to use laser cut materials to address the flatness problem you encountered.

Nice project. Thanks for sharing, Please calculate the torque theoretically as well practically in the next video.

This is dope, electric motors are very interesting to me. EMFs are just interesting in general, I mean, we kinda wouldn't be able to see without them right :D

Maybe water cool one side of the coils? The one side has the magnets and the other side has the water cooling. Great project, keep it up!

Nice work man!

Nice work! Subscribed. 🙌🏼

I just found your Channel and really enjoy your videos I have subscribed I know we all have busy schedules and I hope that you can find time to post more of your educational videos

Nice build man. 🙌💯

Fantastic motor !

Nice work, interesting project, subbed 👍

You have inspired me! Thank you so much!

nice work man

What do you use to run your simulations? I have started to slowly work on my next electric motor project and eventually I'd like to actually make a motor that's actually fairly optimized... as opposed to just throwing together stuff that I have laying around and hope for the best haha.

Wow the possibilities seem endless. Power to the people. Thanks for sharing this with simple enough explanation

Congratulations on your creative spirit in this field. At the time of him I had made several experiments on the matter and my opinion and to use not the three-phase but polyphase or two-degree byfase output , do not insist on the sinus wave form, better tending to square wave without harmonics on the current The greater efficiency is found when the rotor diameter, the height of the package is These are my experiences of years of work in the electronic field, however I will follow you with passion, best wishes .. udos46

Master!! Keep going!

I made alternator like this. It was 4" diameter, rotor 16 pole 1/2" x 1/2" x 1/4" thick NdFeB magnets spaced 1/4" apart. Backing for magnets was 3/16" thick steel. Magnet rotor was set in machined aluminum pockets. Stator was 12 semi-triangular coils , non overlapping, embedded in 3/16" thick epoxy-fiberglass circuit board, pocketed out on circuit board miller. Generator was 10 ohms phase-phase & 120VDC (rectified) output when running at 3000 RPM. This was driven by Honda 4-stroke 1HP weedwacker engine running at idle. power output (feeding through world-wide power supply) produced 12V at 80W for charging military equipment in the field. Weight of entire package (engine, alternator, power supply, gasoline for running 3 hours per day for 2 weeks) weighed just over 15 pounds. The military does not have SMALL portable generator units like this for use in the field. The last one I saw was unit with 2-stroke engine making 120VAC 400Hz 1 phase made for use during the Korean War, weighing about the same.

Very good. this is an idea i had for some time, i'm gonna build mine too

I think you did very well 😀 it actually looks more ballanced than others, the fact it smoothes its self out with more rpm is a good sign 😅 like i said in previous comments i would love to help you develop this! Please respond if you have any thoughts of what you would like to improve on this, i have the the tools to help you, just ask me 😅 great video & I was actually impresed how smooth it ran💙

What a cool project.

Hi Colby, I have built bigger versions of your motor to use as low head hydro turbine generators. I found that using bigger highest strength (N52?) magnets increased the field over the long air gap. The other thing is to compress the windings between two flat surfaces while curing the resin. I was surprised how much experimental compression could be used before any shorted turns occurred. Ordinary mild steel magnet backing worked fine, stray flux is not really a problem. I did not use these as the main advantage is low cogging, important for wind but not hydro.

Very nice job ! 😊

awesome vid!

Love your project

Well, time for me to go learn about what makes these so special.

Great work mate! Liked and subbed👍

Very nice work

Wow. Thank you for sharing!

Nice work!

ProtoPasta makes a Iron Metal-Filled PLA Filament that might be suitable for this project. I believe this is the same Iron-Core based filament used in the Christoph Laimer design.

Nice… good job

Thanks for a really interesting video :)

Thank you for making this video, very interesting to see what you have accomplished. I have also made 2 styles of axial flux generators. 1 is a 24 volt 1000 watt generator and the other is a 48 volt 3000 watt generator, both are for wind energy recovery. Very similar to yours with the copper coils in resin and the magnets. Yours however is much more refined and uses very tight fits and tolerances. Keep with it.

Nice work! 👌.Subscribed to your channel!

Nice project

Nice work. It would interesting to know if you have tried one stator and rotor on both side of the stator. Please keep us posted as this is a new area of

"Man walks on the moon"....lol

Cool! Thanks for sharing.

One on each wheel would make a great electric commuter car, on dry roads of course. You are a modern day George Westinghouse.

This is awesome. I finally found someone like me on KZfaq Lol. You know i have been experimenting with motors for a while too. I made few motors using the tools you have and i failed and succeeded. I am not even an electrical engineer (Mechanical instead) but some how ive fallen in love with motors they are so coooool. However, i stopped designing and building motors i think a year ago because suddenly i needed a metal CNC mill (To build motors) and the 3D printer wasn't sufficient for my needs. So i tried buying one and it turned out that they are so damn expensive but then i found people that build their own cncs and there are many open source designs out there. As mechanical engineer, i love machining. Seeing makers from the community have encouraged me to design and build my own CNC and i am still working on it. As i was working on designing the CNC, lately ive been thinking of designing a very capable 3D printer from scratch too. So as you can see, ive deviated from the motor field just to make tools to help me make better motors Lol. I hope i won't forget why i made the tools in the future Hahaha. Anyways, the last thing i remember experimenting with motors before i abandoned them was casting a stator using epoxy resin mixed with iron powder to make a ferromagnetic core. You see i was using the Protopasta's iron PLA but it sucks and it always broke when i tried to wind the stator because the filament is brittle. At first i tried to cast just small rectangular blocks as specimen (60% iron/ 40% epoxy). They were way stronger then pla. The only problem was that as the epoxy was curing, the powder sunk to the bottom of the block. So at the end one side was more magnetic than the other. So i have 2 suggestions for your design, 1- Try the above (iron powder/epoxy mix) 2- The motor was turning funny because of the 3d prints i think? It kinda felt flimsy. Always use pla as it is the least flexible material. Level your bed and i recommend using glass for the bed. By the way what program did you use for simulation? Maybe do a video about it? Good luck!

Enjoyed your video. Nice hobby. Hope you make something out of it.

This is really impressive Colby. Would making two magnet plates make a lot more power ??? Look forward to more great things from you fella in the future. Nice work Sir.

Brilliant!

Very nice, good work. Do you have info on the Halbach array/ magnet configuration and coils of your axial flux motor? Or if you know any other web resources that has good info on this things. I might try build a similar motor and see if i can manage to make a good one.

Wow, nice! Halbach and backplated just in case ;) I am trying to find best configuration for the linear pm generator. This gives me hope! May I ask for your suggestion for the project of mine at my channel (last video)? Thanks for sharing and keep it coming! P.S. What do you mean by placing the iron at inner and outer diameter? P.P.S. is it me or this could be more efficient if it would be driven in a pulse way? I see some amps jumping every time you start it? Or is it the ampmeter that is going nuts...

Very nice project. Any idea on what torque this motor is capable of?

Very Cool

I've 3D printed a part and then machined smooth surfaces onto that part afterward.

E Bike and Robotic EVs , Aircraft, Medical Equipments can adopt these Axial motors 👍

I enjoyed watching your video, and would like to see whether you could design a real time motor or generator for a ebike or ev . Thanks for sharing your experience.

Nice work. All you need to do now is to refine the making process.

Gota feel good you conceived engineered and developed a functional ptototype

Mercedes is making a similar one for a future car. You should try to run a shaft through the center of the stator, and put a rotor on either side, with the stator in the middle. Double the power with very little size increase.

Hi Colby super interesting topic love it. I suggest picking up a chines mini lath for a couple hundred bucks you could easily true up those critical faces on your printed parts with it. Turning plastic takes no skill at all and there are lots of resources online, not to mention its a ton of fun. Something like a G9729 combo Mill Lath would be optimal if you can afford it and have the space.

Wow! Should try experimenting with Litz wire too.

Awesome!

It's a great job thanks a lot

Awesome! Good job! Did you use any FEA tool or just did it?

That needs dynamic balancing. Six very small BRASS grub screws on radial axes close to each edge (three per edge at 120 degrees) of the outside rotor surface should, in theory, help you get there. Good luck.

Really cool

Just awesome :) !! Don't you think you could get laser cut parts for the discs you mount the magnets on? It should be easy to find a reasonable thickness in some steel with enough permeability. The only problem I see is that you would still need some precision outer rims to get the disc perimeter absolutely flat. Also - it would be really cool if you could somehow measure the torque vs electrical power efficiency!

nice vid - thanks

Im a simple man. I see axial flux. I SMASH that subscribe button

🙌awesome

Very cool. Can you post your sources for magnets, wire, and bearings?

I recommend Protopasta's iron filled PLA for motor core design, it prints like PLA but I recommend using a stainless .8mm nozzle instead of a .4 brass one. I am currently also building an experimental motor that has unique operation.

Cool. I’m inspired. I’m looking at making 4 hub motors for an electric dune buggy

I have been thinking this type of drive might be good for use in a hub motor and wondered if you have considered that as a good application for the technology.

Great job! I was thinking this for last 2 years as an e-bike motor project; especially the part about how to implement hallbach array into the axial flux motor. How did you manage to make an hallbach array? did you order the magnets with a special order?

Love your project, thanks for sharing. Would your design be suitable to slow speed applications such as robot arm joints?
