I would be tempted to add some smaller magnets between the larger. You have some pretty big gaps that could affect some inefficiencies in the system. Some disk magnets.

Hey, at 0:38 use 3 perimeters and wider liner width like 0.55mm for nozzle 0.4, also you can even do overextrude, like 101% filament flow.

where are the 3d files

Use a more permeable material on the poles like iron instead of steel. Reduce the gap between the stator and magnets. Use a second rotor on the other side. Use thinner wire much more windings (calculated for resistance value). Encoder for motor position.

very well made

How many turns on those coils and what voltage are you using. Might be temped to try it.

Hi. Do you have de 3d project files? Thanks

Ai only provide text tools for general description. How do you finalize all the magnetic design and mechanical design? Any tools suggested?

chat gpt dont know how to make motor simple

tupang can u tell me how did u get motor made in freecad after chat gpt what is the process

Is it actually boiling or just steaming? What is the temperature it gets to?

Love the video

good job.can ı get your mail.

very nice, I would also need something like that, how was it created?

This good for precise applications?

what is the motor and controller

Is there a Way to minimize the backlash ?

So clean. Nice work. It's things like this that really make me want to take the plunge and get my first 3D printer and start experimenting. It's just a matter of time once I've hit a critical mass of making and remaking parts due to difficulties getting correct dimentions with hand tools only. Been putting it off for about a year now.

What material?

Can you share an STL for the handle?

like poles repel revers the wiring at the connection

Get a IR sender receiver (like a TCRT5000) and an arduino, put a silver stripe on the drill head, tune it with a pot to pulse on the silver stripe, have it count your turns (cannibalize...or modify, I guess...the drill and have the arduino drive the winding all together. Sort of like a guitar pickup winding machine. Add a servo, with some trial and error, you can dial in the wind angles too). I second the idea of using thinner wire, for complex magnetic, RF voodoo type, reasons its just better for little stuff (be careful guiding thin wire by hand, that stuff will slice right through your skin like a cheese slicer). Also, look at the slop in the rotor. Try an all-thread bolt so you can tighten the axle up on the bearings. That wobble is going to (and probably already is) bite you in the ass.

thanks so much

It would be interesting to build a version of this which has coils behind the magnets, as well as in front of them. That would also include the benefit of adding another shaft bearing, and a retention zone - just in case the rotor flies apart :) .

Nice video; helped me better understand how the lead screw mechanism works. A Scara robot, which doubles as a pen plotter is on my DIY wish-list. One thing I'm curious about is, how you deal with alignment of belts when designing; do you have to do a lot of measuring? Are you using CAD software? I don't have a 3D printer and am using hand tools on my current project, and there's a lot of room for error (I've had to re make parts because I measured or cut pieces inaccurately). I imagine getting things to align is much more important for a Scara robot than on my current mechatronics project (a Rubik's cube solver).

Part details list

add a load

Very nice, I'm happy to see it working, it would be really interesting if you measured the capabilities of this motor, like the rpm and torque under different load conditions as well as the power draw to get the motor efficiency

serious question, what is anything different here? it told how how a motor could be made and you made it as other ones. Nothing special. Maybe you explain more

Is the copper in the coils magnet wire? I.e. resin coated? I cannot tell from the video.

You seem smart enough that you could have purposely switched the coils during installation in order to make two videos....good on you. Cheers

Great job The discord invite is not working

Really awesome to see your progress, and I'm glad my comment could help

I'm happy to see you get it working. Great job. Would be great to see you take this further.

Please, I want to understand how you were able to figure out 3 coils was going the opposite direction with the help of Fleming Right Hand Rule

Thankfully it was a straightforward fix. I'm really glad you kept plugging away.

Great diagnosis and a great explanation of what makes an axial flux motor tick. Nice work. Thanks.

hall effect sensor to fit the right speed and follow the magnetic flux rotation there is one in every brushless you open, you can find one into a cd drive brushless motor. the hall effect is making the timing perfect. but yeah triangular spools with way thinner wires hundreds of turns, this is a good idea to make a little spool turner for this

SPIN IT UP BY HAND FIRST!

ChatGPT isn't designed for this kind of task. It's like asking a bright high school student who has read about it but never designed a similar motor himself. The problem with the design is that the pulses delivered to the motor need to be synchronised with the arrival of the magnet, the speed at which that happens depends upon the speed and inertia of the rotor, and and you don't have any sensors to feed that information back to the controller.

For six coils you need four magnets, 2 north and 2 south for the rotor

what power does it generate when spun??..

I think your problem is not in the motor, but in the drive electronics. When I look for how a pancake motor works, I find this: ua-cam.com/video/PFJ38sZE4Ms/v-deo.html This motor uses a commutator with brushes, which energises different coils as the motor turns, dependent on the position of the rotor - but I don't see any commutator in your design. You said it's a 3-phase motor, so I'm guessing that there are 6 wires coming out of the motor in 3 pairs - call them paire-A, B, C. If you energise A, it will energise 2 coils (A1 & A2), and they will attract the magnets closest to them and, the motor will go to one static position and stay there. If you de-energise pair-A and energise the next pair of wires (B), coils B1 & B2 will energise, and the rotor will rotate to the next position and stay there. Energising C will make it go to the next position, and if you keep going A B C A B C A B C, it will go around - but the speed of rotation is dependent on how fast you go from A to B to C to A etc. What you have at the moment is a stepper motor. What you need is a bit of electronics that will switch your coils on one after the other, starting slowly and accelerating up to the required speed. So - what you want to do is speed up the stepping - but not from the point of starting the motor - it must start slowly then accelerate up to the desired speed by increasing the A-B-C-A frequency. *_HOWEVER_* - if the motor is loaded mechanically, and slows down, you need to slow down the selection of the coils, or the coils and rotor will get out of step, and you will lose torque, so the frequency of your coil selection has to be controlled by the rotation of the motor - and more specifically, by its _position._ Brushes and a commutator do that for you, but a commutator is hae=rd to make, and you can also do it with optical position sensors, magnetic position sensors, etc. If the motor gets up to speed and is not required to produce much torque, you can make the pulses to the coils narrower, so each pair is energised for less time - to save electricity and heating the coils. If I was doing this, I would have a processor like an Arduino between the sensors and the coil drivers - but that's just because I'd be using something I have used before. There are lots of ways you could do it (transistorised circuit, for example) Good luck. Edit : You could do worse than to talk to this guy : ua-cam.com/video/1isqsi9h7c4/v-deo.html His motor is functionally the same as yours - 3 pairs of coils, 8 magnets, and brushless - so he must have got the electronics sorted out, as his is running and sounds good. Maybe he can recommend ready-made electronics. Check the resistance of his coils against yours, but I think you will both have low resistance coils. You seem to be using thickish wire, and so does he.

magnetic flux is stronger when you have 2 disks with magnets ether side, air gap must be smaller, but you can overcome a lot of the inefficiency's with a sensor feedback motor driver. coreless motors are all about super efficiency with regards to losses in the iron cores / cogging and drag. because of this you have a harder time keeping the flux inside the coils, and it can flit through the gaps. tying the magnet flux in pairs will increase the effort needed to push the flux around the coil, giving you better torque. the back emf type driver you have reads the zero point crossing of the floating phase, your motor needs to have a faster pickup and better flywheel effect in order for the controller to establish stable drive, you can help by adding more mass to the flywheel, and reducing the initial voltage. but without access the the variables in the micro controller you can not really tune it for this motor well. a super quick fix for proof, you can attach a drill to another similar sized motor and use it as a 3 phase generator.

Do you genuinely know so little of physics and engineering that you seriously believe that you are doing something unusual? Forget AI, read a damn book about basic electromagnetism then you would understand how incredibly dumb you sound.

Bro, how did u design the 3D parts? With help of Chatgpt? Or done by yourself?

How did you count the number of turns
