      That is because these motors are extremely popular in rc cars and quadcopters, as they are much more powerful than their brushed counterparts.

      +Tkj Tkj na. I'm a RC hobbyist so I understand this. One benefit is you can seal it off and waterproof it, another you can maintain easily, also they use 2 positives and 1 negative in the motor for increased magnetism, and therefore increased RPM

      if it breaks, its likely the bell that needs to be replaced (the part with the permanent magnets) so you don't have to throw away the whole motor

    I love the way we make the new thing the best thing ever. I've got a 47 year old Kirby vacuum on my work bench, and while its commutator is a bit worn, it still runs great, plenty of power, no sparking. You can tell its been worked hard. It is beat up, chipped, and worn out, but the motor is still fine. This is the second 1970 Kirby Classic Omega I've had in six months that is worked to death, but still running. Meantime, I've also got my second six year old Rainbow E2 sitting on the floor here with a motor that is toast after having a blade come loose in the cord, and fry the circuit board. Nevertheless, "a carbon brush motor should never be used where long life and reliability is a necessity." It is a lot easier and cheaper to replace carbon brushes than it is to replace brushless motors and circuit boards. In fact, replacing the entire motor is cheaper on the carbon brush motor.

    Excellent video! I was writing an article about a controller upgrade for an e-bike with a brushless hub motor, and this is exactly what I was looking for. Unfortunately, it seems the timing is off on the controller I'm using and the coils are energized too long, causing the motor to fight itself and drawing high power at higher RPM. Sort of like a relay race where the runner passing the baton won't let go soon enough! Thanks again for the video.

      Yeah. It produces alternating poles at each coil so it's basically AC. The only difference is it runs on a DC power supply. So it's "rectified" twice, from AC, to DC, back to "AC".

    • @jpgiebl
      @jpgiebl Před 4 lety

      3-Phase synchronous motor is a collective term which refers to reluctance motors und 3 phase permanent magnet motors. The later being a synonym for brushless dc.

    • @simonm1447
      @simonm1447 Před 4 lety

      The difference is normal synchronous motors have coils in the rotor (and brushes), while BLDC motors have permanent magnets.
      BLDC is often used in powerful cordless tools, because with brushed universal motors they tend to get hot at the brushes (because of the low voltage, and high currents) and are inferior when they have to supply much power for a longer time.
      Normal synchronous motors are often used as generators in power plants, because they can adjust power output by the power put in the rotor coils, and in car alternators (which are technically similar to generators in power plants, only in a much smaller scale).

    • @hassan_a9

    • @ronbrown8611
      @ronbrown8611 Před 7 lety +1

      focus on how it is eneriezed. notice the plus and minus signs. this will indicate the current flow and. Also notice there are only 3 wires coming out of the motor. that's why it's called a 3 phase motor. I guess you could have more phases. My knowledge is also extremely low on how they are actually commutated but i would like to learn how it works.
      Again, its just a way to simplify the energizing of the electromagnet. its easier to enrgize 1 thing and not 2

      @ima hinasyon you can do this with an h-bridge of mosfets to redirect current to the opposite direction using a microcontroller to read the hall effect sensor for timing and send signals triggering the mosfets to do the redirects

    Animation isn't°exactly correct. The angle between rotor and stator flux should be keep in range 60-120°. Animation shows that angle is in range 90-180° which cause high torque ripple and low efficient motor operation.

(I'm taking notes & duplicating the drawings, but I don't understand the coil connections at this point. Maybe if I smack it around in my mind a bit I'll see it. ? ...)

    • @0711floflo
      @0711floflo Před 6 lety

      I don't see the connection very well too, but I can say that there are 3 couples of coils, so 1 is connected to another one.
      Two pairs of coils are connected such that the current goes through a first pair, then another!
      I don't know if I answer your question , but that's what I understood

    Not really DC, but rather just a synchronous motor, with permanent rotor. (rotor-stator, does not matter)

    • @jessiehawes5062
      @jessiehawes5062 Před 9 lety +1

      František Němeček yeah it is really a dc motor. it has to have a controller to alternate the current to the correct coils to make it work. it is not an ac current.

    •  Před 9 lety +5

      ***** What the electronic controller does with the DC power is exactly the transformation to AC - no matter the AC is not sinus, but rectangular.
      And even better: It is not jus single rectangle -+-+-, of two ALTERNING states (of a single phase-wire), but in fact three states" +0-0+0-0... So what it makes is in fact a simple rectangular aproximation to the sinus shape.
      Just look on the charts within the video: It makes its own AC phases to power up the motor and to create the rotating magnetic field. Just the 3-phases wiring as usual from powerplants.

    • @nguyenhoanganhvu9990
      @nguyenhoanganhvu9990 Před 6 lety

      because if the motor without driver. it will useless. so you can image the brushless motor and driver is 1 part. and the power for it is DC.beside, the Ideal for bldc is brushed dc motor.so...yeah. if you thinking about you can put the 3 phase ac to it and it still run. yes if you look this side the motor will call "PMSM". 2 of them are correct for this one.they are not the same but really hard to separate them.sorry if i wrong english too much.haha

      @user-se2zf7xp6l Před 5 lety

      Nguyễn Hoàng Anh Vũ I think there is no difference between what kind of power you provide BEFORE the inverter. Inverter produces AC. And PMSM will not work without a controller and hall sensors as well! So what’s the difference between PMSM and BLDC? BLDC can also work on sinusoidal AC. What’s the difference then?

    @matsv201 Před 8 lety +13

    A current that is shifting is not a DC current. Its electrics 101.... A brushless DC motor is not a DC motor at all, its AC motor that uses a inverter.
    There is not really a need for a sensor, even that a lot of motors have it. Running on dead rekening work quite well, at least in the medium RPM levels.

    • @temodeed

    • @superdau

      A brushed DC motor also switches the current around in the coils. So they are AC motors, right?

    • @ryantoomey611
      @ryantoomey611 Před 6 lety +2

      Yeah, a brushed motor uses a commutator, so even though it is internally AC, it is supplied by a DC voltage.

    @xoOPhoenixOox Před 6 lety +3

    Just use 3 phase ac to power the coils and you'll get a nice RMF. No need for a controller (inverter). Also, while we're at it, can we stop calling it "bushless dc"? This is clearly an ac motor...

    • @huseyin.goktas
      @huseyin.goktas Před 6 lety +2

      It is supplied with dc thus it is a dc motor. If you are a user you don't care how it is work, only power type, and torque, speed characteristics matter.
