    Hope you guys enjoyed the video! This thing was really fun to make and test. A bit scary too. Nevertheless, it was a cool project, and I would love to do more with the motor in the future. Let me know if you have any ideas.

      Compared to electrical steel the relative permeability of magnetic filament is awful, less than 1%. On the flip side it's up to 8 times better than air or non-ferrous filaments so I'd expect a significant reduction in torque with a non-ferrous core.

    Hello Michael i had a couple ideas for possible improvements, there is a couple ways i think this could be be helped. I would recomend trying to get it balanced even if its statically. IDk where you are but it would be fun to put this on our dynamic balance machine and see how much it is out. it being round its probably close but i wonder if the infil has biased this to a certain area. my ideas off the top of head would be to put the printed parts into a jar and pack it tightly with kinetic sand. then spin it up to around 900 rpm or so inside of a oven to aneal it while rotating. a cheap air drill could probably be used if its metal to workk ouut something that can take the heat. i se you have printed it with the layer lines xially around the body of the motor, i would like to see if some thing metal mesh could be installed on the outside of the motor body tieing the layer/grain structure together better. eitehr heat set it in or use some UV resin and instal it and dip it in resin and agin spin it during the cure. also i feel like you should look into getting some statorade its a ferro fluid that helps disipate heat. probably rambling also sorry for the spelling and grammer its not my strong point. great project and video tho dude cheers

    A very impressive motor.
    In order to avoid iron you can use the BLDC axial flux configuration, which has the additional advantage to offer the minimum of structural materials. I like the version where a single coil plate with mounting points sits between two rotating permanent magnet plates. This configuration gives the most torque. The rotating plates should be made of fiber-reinforced epoxy (G10) plate material, especially if you operate them at higher rotational speeds (200 to 500 rps).
    You can have a look at such motors unter "How to make Brushless motor from clear acrylic" in the American Tech TH-cam channel.

  • @Sabotage_Labs

    That is pretty slick! I would consider maybe at least PETG for heat tolerance. Those motors can get toasty.
    Smaller motors are so cheap that I wouldn't want to put that much time into something I can get for $20-30. But for something big or custom build...sure.
    Might be a little less crash resistant too. I've run some motors through dirt and hard ground, blew them out and flew again. Could see plastics breaking more easily. But hey.... fly, crash, repair and repeat. As long as the insides are still good...new print job and you're back up. Can't do that with standard motors.

    did you cure a print in water?

    that's strong
    but I heard the PWM signal coming out like every other adjustable speed AC motor

    If you could print with two different types of materials at the same time, could you print a ready to run motor?

    Maybe, just maybe, it could be useful with liquid cooling circuit, and wrapped in carbon. Otherwise it either melts or flies into shrapnel eventually. It would be a much more practical approach to use laser cut special steel for an iron core, while keeping the 3d printed hallbach array.
    Anyway, what is phase to phase resistance and no-load current?

    That's pretty neat I may have to try this. But I am trying to use a 3 phase rc car motor in a fan. And can find a stand alone controller for the motor. The fan is a 10" dewalt fan lol

      You need an Arduino, along with the Battery and ESC for the motor, throw in a cheap potentiometer and with some real simple code you can adjust the speed with the pot. (you can also add max/min speed etc) I built a surfboard with Lidar + Sonar for pre-mapping Talla Aquaduct in Scotland before Abyss solutions brought their $100k+ scanner from OZ, they didn't want to lose it in the tunnel. did the same job but mine cost about 30 bucks 🤔

    Hey, following Christophs instructions I wasn’t at all able to fit the windings into the stator. How did you do that?

    • @michaelrechtin
      @michaelrechtin  2 ปีที่แล้ว +1

      Yeah his instructions on windings were a bit misleading. I used half the number of turns that he says to use

      @@michaelrechtin Unfortunately my motor didn’t work with fewer windings. The project is abandoned now. Still have all the printed parts and everything. I assembled it completely but it never ran.
      I then designed my own motor in CAD which did run very nice. If you’re interested I could send you the CAD files. :)
      My motor is an inside rotor design tho

    Does this have enough torque to maybe make an e-scooter with it?

    Dumb question, but what makes that weed Wacker noise? Is it air molecule I thought the motor is supposed to be silent?

    use a bigger prop to keep the rev under 5000 /min 20% under the tested rev. and keep the temp low because the plastic gets softer by the degree temp increase. good luck ery nice project.
