  1. Hours over Hours of lectures and i never got these 4 minutes of comprehension

  2. I am 28 years old now and all that damn donkey reminds me of is my parents and Coach Todd, when I was 6 or 7 years old, during swim lessons always promising to not back up once i dove in the water to swim to them. I'll never forgive them. 😒

  3. Ok…so what if you reverse the design? Putting the coils in a ring around the permanent magnets so that the center of the ring can be open space, no drive shaft necessary. Or more accurately, the permanent magnets would be fixed onto the ends of prop blades and set into a C-channel ring that holds the motor coils. So rather than having to bolt an existing prop to a drive shaft of a motor, the two can be one apparatus. I also wonder what power differences the two designs might have between traditional and my own. My design will be able to handle an exponentially higher amount of torque than a traditional shaft and bracket drive system, but will it be able to create the RPMs necessary to even achieve thrust? The goal in mind is a FAR 103 compliant ultralight plane that is fully electric, but capable of vertical to near vertical takeoff. I want to be able to put my props INSIDE the wings and on the tail, rotatating the pitch electronically through independently controlled shafts that would also provide structural support in the wings (the props would look like gyroscopes sort of) this would allow my aerial vehicles to takeoff like helicopters but fly like airplanes. Since the dawn of time, man has wanted to fly. I think everyone should be able to. So its my dream to create safe, affordable aerial vehicles everyone can fly for under $20,000. I'm gonna be the Gerald Ford of the sky

  5. How does startup occur? Without some initial inertia to rotor doesn't the rotating magnetic field on stator go to fast for the rotor to get going?

  7. good explained video.however i have a question. The tree coil with 120 ° should be energized with AC Current.TRUE or Fasle. Because as i also lear in another source stator that create Rotate magnet fiel schoul be energized with AC Current. why the coils in BLDC are energized with DC Current?????

  9. Simple, yet engineering genius. Still like old Brushy too😊🇺🇸❤👍🙏

  11. Bonjour lesic vous mettez un titre en français et ça cause english…..c'est oripilant…….

  12. If we keep the magnetic on the rotor and coil on the stator so we never need brush and work much better

  19. Does this mean some kind of electronic chip is needed to determine when to energize which coil?

  21. I'm done enough is enough I'm going forward with my life …fuk that family… always discriminate against me and alienate me now u jealous envious

  33. Information to all Indian BE students,
    It's better to quit the BE and start leading with lesics or other you tube videos or better to join a BE in other countries,
    We won't learn anything In india

  35. I am pretty sure hall sensors are used only at lower speeds when bemf is not high enough

  37. BLDC motors aren't DC motors at all. They need a motor controller to convert the DC to AC for proper winding commutation. The motor controller takes the place of mechanical brushes in a DC brush motor for commutation.
    BLDC motors are still multiphase AC motors – they just don't have brushes to wear out. They instead use Mosfets which can burn out.

  40. Good bye brushed motors, now you are history from the past .
