Please describe ferromagnetic for me if you please

@@DaProductionsDrawings Ferromagnetic materials have very little magnet properties even if there is no source that produces any magnetic field in the environment. When they enter the magnetic field, they show magnetization very quickly. These materials should be used instead of all the plastics used in the video. For example; iron.

I'm sure there will be home fabrication machines that can make a motor all in one, but I doubt it would be entirely "printed," although it is possible.. but think about the fact that the coil windings must be densely packed and also coated in something to prevent short circuits. If the machine could switch to a 0.05mm nozzle then back to a standard 0.4mm on the fly, then maybe it could print the "casing" insulation around the coil windings thin enough to have them packed densely enough to be feasible. One thing is for sure: home manufacturing is going to continue growing and becoming much more advanced, giving everyday people means of production that we've never had before. Combine that with AI assisted design, and it's a bright future for hobbyist makers, and the cheapskate diy enthusiast

What sbout the magnets, can you print magnets?

@@SoulAir probably not, but not all motors need permanent magnets. Mahle for example has recently developed one that would even be suitable for EVs.

@@Embassy_of_Jupiter Youre right, but I actually looked it up and apparently you can print magnets.

i would say it is most likely possible right now. but it would be expensive and no one has a reason to figure out yet. we are kinda doing it in the D.o.D already as you mentioned with a machine similar to the continious fiber. they actually lay the wires down with robots inside of certian planes as they assembly is being printed to house the electronics. when i build commerical plane parts for a Spirit Supplier the only "robot" we had at first wasjust a large drill press that could change sizes and put rivets in the holes without stopping....we did get one that drilled holes before i left...not sure if they ever got it working effectivly... but thats what you get when you send the tech collage kids to the machines instead of the veterans XD...i mean if the engineers actually knew things they were suppose to in that plant it shoulda been a fun new toy to learn.

Thanks

Probably a team of mechanical and electrical, or just a mechanical who is well researched on electromagnets.

Thanks

Looks like just a speed controller wired in.

yes, thats what the contorller, the so called ESC does. thats the thing in the yellow heatshrink in the video (note the DC supply but 3 phases). with a ser vo tester you can create a 20kHz PWM signal and by chanign the duty cycle adjust the speed. these are all off the shelf componentens thta are cheap, so you can achieve the same without coding yoursefl, there is code involved on a lower level tho.

Only an esc which is hardware.

@@arturceller320 and runs software...

Yes it is

A magnetic sensor isn't explicitly required. The ESC hardware has the capability to detect the current orientation of motor, from the phase wires itself

People call it a dc motor because thats what comes from the power source. It does switch to ac though

@Oltro 15 it's 3 phase ac motor running off of 3 phase ac that comes from a inverter 🤦thats like saying my cars engine is a dinosaur engine because it runs off of dead dinosaurs.

But this motor is literally called brushless DC motor

@@box420 Oil is from trees

Thank you 😊

Yes... This is an brushless motor that is powered with dc power making it a dc motor.

Yes... Really... They are pretty common in the RC world. All DC batteries and speed controllers. They make a digital signal pulsing the electromagnets on and off pulling the rotor round n round.
