Brushless DC Motor, How it works ?

The working of a BLDC motor is explained in this video with help of animation.

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've looked all over for a video that can easily explain the difference between brushed and brushless motors, and you have done so perfectly. It makes perfect sense now! Thank you!

Awesome! You guys rock! Thanks for making this and sharing it with the world on Youtube! Really helps me study my EE.

Thanks for unbiasedly explain this. Everywhere else I looked were talking about RC vehicles.

U ARE THE ONLY DUDE WHO CAN EXPLAIN THIS STUFF WITHOUT SCREWING ME UP THANKS U SAVE LIVES!!

Amazing explanation and animation at the same time. The optimum way of teaching.

Brilliant work guys...I loved each electrical and mechanical videos you made...
thank you and keep up your excellent work.

[DeepakJulien]

Thanks for producing such videos that enable a layman to understand the basics.

just to say, your channel is great. It helps a lot to quite understand how this components work, not just to understand but to visualise them. Great work and keep it up. (y)

I *did* have a nice introduction on the working of BLDC motors. Thank *you*! ;)

[luoychau]

Thank you. I have been wondering about this for a while.

[winkipinky]

Finally a well made video explaining these motors. Thank you!

[intheframewye]

I live these informative videos! Thank you Learn Engineering!

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.

best explanation - short, clear and simple.  Saw about half a dozen other videos that got me more confused and took half hour +

[motojauntx]

Thanks so much! Best explanation of this concept I’ve seen yet!!!

Thank you for sharing knowledge

So technically a BLDC is a Three-Phase AC Motor. And a Three-Phase AC Motor is a continuously rotating Stepper Motor.

Finally the video I've been looking for I understand the basics now

Simple yet beautiful explanation. You made my day !
