    I built a 3D printed brushless DC (BLDC) motor and motor driver circuit. The entire project - the mechanical design, the drive circuit, and the code - was completed in just three days. The motor ended up being surprisingly powerful. This was technically an extra credit project for a college lab class, but I took it far above and beyond the actual requirements.

    I have been trying for almost a year to wrap my head around the actual mechanisms that make a DC motor work. I’ve likely watched almost every video on TH-cam on this subject but wasn’t able to ever fully grasp it - that is until seeing your video.
    This video and your demonstration just made everything click so well - as another said - the best bldc video on the internet. Very simple and well-explained. Thank you for your work.

      I agree to put this together can drive someone crazy. It is really on point for a TH-cam video.
      But it is not a circuitry that will last long or is efficient you will need lots of current that comes with heat. P-type pose a bigger resistance than n-type which means heat. Also the Nano cannot supply enough current to the lo side fets, therefore they are not open in time which poses an even bigger resistance which means heat. To connect the gpios directly to the lo side gates is dangerous they will get damaged sooner or later, the fets supply lots of current during closing the pull downs won't change that. I think if you add bjt's to the lo side gates aswell you have a good circuitry to play around with.
      Anyway it doesn't need to be efficient the task was to show how this works and he could not have made a better job.

      .I was about to say that those magnets are not that fast because of the small diameter, but assuming a span of 60mm those magnets have a tangential velocity of around 170kph or 105mph (at 15k RPM) 😅 But - based on the cross-sectional view at 0:38 the centre of mass of each magnet is below the surface and no force is applied that could toss them out of there. Which leaves a breakage of the plastic carrier as a potential danger. Considering the yield strength of typical 3D printing filaments and the low weights at work I would bet on the carrier. The loosening of the screw is most probably the biggest concern 🤔
      I think the best approach is to calculate the actual risk and then be better safe than sorry nonetheless

    Nice design. I have found that magnets will come out from friction fits over time, so I now slide them into a slot, rather than friction-fit. I make the slot have 1 layer of 3d printed plastic, like 0.1mm or 0.2mm between the bottom of the magnet surface to ensure the can't come out. I even found that crazy glue isn't even good enough as it won't stick to the nickel coating on the magnet that well.

      @@LeviJanssen Ok, then you should design a hole in the middle so you can run wires through it, so when you create an eventual robot arm you have a way of easily running the wires. Given that this is a 3D printed design, it would finally be easy to do that. Finding strong motors with a hole in the middle is quite hard still, so this could be game changer. Can't wait til you add a planetary gearbox to your design with say a 6:1 ratio so it's backdrivable and you can detect the reverse torque against the motor.

    You can use an odd number of permanent magnets if you have them all the same polarity and have the drive coils alternate polarity. Then you can drive it at half duty cycle to push it away from one and towards the other with one switching element. Then you could use a H bridge to make it 100% duty by reversing the polarity every other cycle. I've built a couple of motors like this with success.

      @@saeedgnu My motors use around 15uW to turn at around 60-120 rpm running in half duty using a reed switch to trigger. My smaller one has three magnets and six coils. Since there are three magnets and six coils, it's easy enough to use the magnets to trigger one half of the drive wave form.
      Of course, if you want full duty things get a lot more complicated. Maybe you could just use some diodes and a change over reed switch? But you might want more dead spot between phase energization and that wouldn't allow it.
      Transistors would allow precise timings and are very efficient for switching, but with a 15uW motor they massively increase the total system energy consumption. However if you used ball bearings instead of jewel bearings and rewound the coils with thicker wire, you could massively increase the RPM and torque, increasing the power consumption of the motor which would decrease the proportion of the energy consumption that goes to switching.

    You can also operate it with an electronic speed controller (ESC). I guess you have eddy current losses in the core screws of the coils. The coils should not be too long. You can use FEMM to have a look at the magnetic field distribution of the permanent magnet disks. You can use a magnetic manifold disk made of low carbon steel at the opposite site of the permanent magnets to the coils to increase the magnetic flux. FEMM shows that it helps a lot. The best ist to use a rotor with two permanent magnet rotor disks with magnetic manifolds at both sides of the coils.
    The coils should not be longer than the length of the permanent magnets. In order to get a good flux penetration, the inner diameter of the coils should not be smaller than the outer diameter of the permanent magnet disks. You can use FEMM for motor optimization. It is a trade-off between maximum flux through the coils and minimum coil resistance. Using more height for the coils will reduce the coil inner resistance but also drop the magnetic flux through the coils. I've found that 6 coils and 8 permanent magnets is a good number. If you need more motor speed, you can reduce to 3 coils and 4 permanent magnets. If you need more torque you can get to 12 coils and 16 permanent magnets.
    You can make two of these motors to use one as a generator for a dynamometer for power tests. You can break the generator by use of a 3-phase rectifier and an active constant voltage load to set the break operating point to a more or less constant motor speed. Until now you just operated the motor under idle conditions, not under a break load. You have to consider that not the motor speed is important but the power and the efficiency under a certain motor speed.

      @@abdelkrimaldagamseh7754 the easiest way is make a test coil with a certain number of windings, spin the rotor with the desired speed or with a well determined speed and measure the rms-voltage at the coil.
      Now you have the winding to voltage / speed ratio and you can calculate the winding number for a certain voltage and speed. It is proportional to the voltage and inverse proportional to the speed.
      The wire perimeter should be selected to get less than 7 to 10 A per mm square.

    I've had a lot of success with putting air core coils on both sides of the magnets. This eliminates hysteresis from metal cores. It also "pinches" the magnet between the two coil fields instead of thrusting against the bearing, eliminating lateral bearing loads. The smaller the coil/magnet gap, the more force realized. Hope these ideas help with your next version :)

    • @marcobassini3576
      @marcobassini3576 9 หลายเดือนก่อน

      Commercial ESCs have rotor position sensing (through back EMF) and hence keep the rotating magnetic field in sync with the current applied to coils. They never lose sync and always keep the motor running. This toy ESC continuously loses sync (even with no load applied) and hence the motor stalls. It is unusable for everything except TH-cam videos.
      Additionally those MOSFETs are driven at 5V maximum (the voltage of the microcontroller output pins, if not even 3.3V!!), which usually it is not enough to turn them fully on, and hence the losses are high. On top of the horrendous losses of the motor (no ferromagnetic core).

    A good scale up might be arranging your permanent magnets in a halbach array. This arrangement causes the magnetic field to focus toward your stator electromagnets. It might be interesting to see how much this enhances the motor efficiency. Field strength from the permanent magnets would be somewhat stronger for more mass in magnets. Then an identical arrangement on the othe side of the rotor to make full use of the stator magnetic field.

    Which course path are you in? Great video! Have a detailed walk through on entire project?

    Amazing job! I’d start looking into some kind of shielding or retention incase anything let’s loose. At 15k, assuming you have a 30mm diameter magnet circle, those magnets are doing 75 meters per second, enough to really break stuff if something happened. How does it work with a load? I’m not super familiar with motor design.

    How do they fit that whole thing in a standard brushless 4010 fan for example? It's a mystery to me.

    Great video! On a unrelated topic. Does anyone know what is the name of the music that is playing at 3:45 - 4:42 and at some other points in the video? Kinda hard to find the name of it because there are no lyrics.

    Can you measure how much torque it produces throughout the range of RPMs?

    Looks good, but wouldn't it make sense to have a second set of coils above the permanent magnets?

    Hey dude, nice vid! Now add the second set of coils from upside! You'll double your power and usage of magnets!
    BTW 3d printing is mostly not strong enough for high performance motors.

    I hope you wear protective glases at 15.000 RPM, one of those magnets can come flying your way or a shattered plastic piece.

    I'm sure someone could take the sound from the motor and turn that into samples to use as a digital instrument. I'm kind of interested to see what that would sound like.
