Brushless DC Motor, How it works ?- can make video for linear actuator motor.....
and this video is DAM good for INTRO
- great explanation!! that donkey's comparison...XDD
-
- The videos r really good. Contains lot of informations.
Plz add some more videos related to electrical engineering
- Very informative, and clear, thanks sir.
- good video (;
- If it has an electronic inverter, why we need to use permanent magnet? Is it because we want it brushless and easy to rotate?
-
- Wer es danach noch nicht versteht.
- Not really DC, but rather just a synchronous motor, with permanent rotor. (rotor-stator, does not matter)
- excellent explanation ... thanks 
- Fuckin' amazing
- Brushless DC motors are used in home appliances; like fans. How about electric cars? I think they use motors with brushes. That means motors with brushes give more power than the brushless motors. Could you do a video on HOW THE MOTORS OF QUARDCOPTERS WORK. Is it brushless or with brushes. Please do a video.
- Brilliant work guys...I loved each electrical and mechanical videos you made...
thank you and keep up your excellent work.
- This basically described a 3-phase AC motor, with an external electronic inverter to convert DC to square (!) wave AC.

Incidentally, brush motors also convert DC to AC, but they do it mechanically instead of with a controller.
- in overunitydevice might get stuck due to atraction,parrelel forces should besafer 
- Hmmm...the graph at 2:50 shows me square wave AC. And in your earlier description, you mentioned reversing the polarity of the trailing coils, along with saying even before that, how the opposite coils get their polarity reversed. Sounds like AC. Which, oddly, we know stands for alternating current, when we know that we are alternating the voltage, and the current is a by-product of the load.
- Terima kasih atas penerangannya, senang nak faham.
- como é o esquema de cores para ligação deste motor ? GFH2G5 ??
- This Video is really good but I still have some questions
There is no sensor in Brushless DC motors for RC purpose so how does it work without that sensor?
I have some of these motors and they don't have six but 9 coils, does that mean that there are 3 coils serial placed for each line?
