How do you run it? Through controller or direct DC power if controller, which voltage and watts rating. Mine run too fast and burnt my 48 v 1000 watts controller and my battery pack BMS. Need help to know how to run it.

Hi Colbi. This is Lipon from Bangladesh. How could we be connected?

What is your mic on this video? Sounds good

One of the best DIY motors I have seen. I think a push + pull coil config and some iron/ferrite inserts would increase the strength a ton. Axial designs are usually better for torque than high RPM. You can use a jig to get precision. Using a single piece of metal mounted to the bearing as a measuring stick to glue each part 1 by 1 as you turn it will make sure they are each exactly the same distance from the bearing. The same can be done for each direction using a single mounting point and set dimension for repeatability.

just curious how your project was going ,i did see acouple of the pcb manufactureers now offer pretty checp cnc work and even metal printing

awesome

Pl give me coil direction of 12 coil stater three phase axial flux bldc motor

Question : if to make winding not copper but iron , maybe it will be better?

Ive been designing exactly this plus more for over 15 years

I wonder if there was a way to put sintered cylinders inside the coils to concentrate the magnetic flux if it would help improve efficiency. Or even a steel (ferrous) bobbin type contraption. This way the magnetic field is directed rather than just a field. Very cool that it ran so well...did have an odd vibration harmonic...but it ran quite well! Long term under load does it get hot? Keep em coming!!!!

Any updates on this? I'll go check your channel next. I'm looking for efficient generator designs

I wonder why did you use a 3-phase scheme if there is no angle shift in 12N24P scheme? All your slots are at a same angle to poles. It's a wasting of MOSFETS imho

can you make a video comparing the torque between a shaft flux motor and a regular radial flux motor of the same size? i read that the torque of a shaft flux motor is 4 times higher than a regular radial flux motor but i don't see anyone making a video comparing them

is it possible to do it using PCB coil stator ?

Nice!

Really can this do heavy duty application?

Why not integrate a centrifugal fan into the rotor design??/ I think it would work for the very highest power motors, if its encased in epoxy, just prevent magnetic dust, and all should be well. If centrifugal force self cleans, it would be perfect for bolt on car wheel hub evs. 2 or 4 wd could even be converted with kits, If cars were simpler, it wouldnt be bad, at all.

Thank you for your educational videos.

Mix the 3D printing resin with graphene to make it stronger so it won’t bend.

Nice build man. 🙌💯

Love your project

Hey Colby, I'm researching building my own Axial Flux motor. My question is how strong is the 3d printed housing? Even with properly gauged wires, the housing may not be suitable to provide 1/2 horsepower or so. Any comments on that? Love your explanations.

Hi Colby I am trying to build a Linear Generator & have much the same problems with it that you have with your motor. The Coil is just a Coil of wire. However, to direct the Magnetic Flux of the Oscillating Magnetic Ring, I need to surround this coil with a Laminated Iron Clam Shell. This I can not make myself, however like you I could make a mold & cast the 2 halves of the Clam Shell out of Iron Filings & epoxy. Have you found any way to design & build such things, & calculate how efficient it would be compared to Laminated Sheets ? Thank you for sharing your project ! James

If big copper spins in center, heavy, would there be forces, like copper affect magnet when moving or aluminium, like ice boils under pressure

Awesome!

2 years and nothing form your side bro upload and bldc motor video

thanks bro for make this video keep on making video bro why do you have to stop ???

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.

can u share the filaments u used for thes models.

Are you alive?

For what i am doing i really could use a hand and a setup like that. And another coil i will talk aboit if anyone is up to helping. I have a very nice machine requiring a setup

Hey would you be interested in a side project where that design will flourish?

Dunno what your progress on the mold has been, but I would play with a rigid shell / mold that a thin hard silicone liner is keyed to. My thought process is that there'd be very little in deformation from your "pressing" method this way. Also putting it all in a pressure pot to shrink the air bubbles is a good idea too!

Thanks for a really interesting video :)

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.

nice motor's but not sure these are so much the classic axial flux design as your coils seem a bit more traditional, have you tried to take copper coil and flattening the wire to lay on top of itself per wrap, similar to like how a 3d print layers itself. you can pull round wire between two rollers and it will flatten and is controllable enough to get nominal diameters, or widths.

Nice project

한 가지 제안한다면 영구자석을 사용하는 대신 구리 권선을 이용하여 모터를 돌릴 수 있는 방안을 찾으면 좋겠습니다. 테슬라나 현대나 자동차 회사들이 전기자동차 모터에 관심을 가지고 이에 관하여 연구하고 있습니다.

It would be interesting to see what would happen if you used one of your phases as a drive and put voltage into that phase see what type of RPMs you can get and what the other two phases give you for output 🤯

Was so glad to find you😅

Am so glad to see all your iterations of this setup😅i am just getting into making my own axial flux motors and love your experiments, like i said in previous comments i would love to help you with this, I have a $10,000 Tig welder and a metal lathe so would love to help you advance this if you need 😅

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💙

I could turn those parts on my metal lathe for you and send them from Australia 🌏 to the US with not much cost above postage, cause I would like to help you push it to the maximum efficiency and then I could do it for myself, let me know what you think, loving your build video, and I have the tools you need 😅

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

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

Instead of telling us about what you re going to do, tell us more about the motor.

what is cromoly?? is it the same as aluminum??

Probably late to say but gonna say anyway, machine the surface of the print,

Great work! Could you please report the inverter unit model used to drive the motor? Thanks!!
