This is the single best explanation on BLDC motors I’ve ever seen. I really honestly watched it twice it was so good. Learnt loads thank you

[delinlo]

I’ve been watching videos on bldcs, escs and everything for a few years now. This is the single best video I’ve seen yet. It cleared up everything and it’s the first time I actually understand the coil wiring well enough to say I would be ready to rewire a motor myself. Thank you so much. Liked, subbed and commented! Keep on going!

Dude, I have never seen someone explain something that made so much sense the first time. 👍

Around 8:30, the BEC actually means that when the battery voltage drops too low, the ESC cuts power to the motor to 1) avoid damage to the battery and 2) keep the rest of the controls working (receiver and servos), that feature was introduced to avoid RC plane loss of control and resulting crashes when the battery was too low.

I've been interested in several projects involving BLDC motors, and your video shed so much light and answered so many of my questions. Thanks a lot for making this video!

[swapnilgautam]

sir, i am studying mechatronics engineering right now and i love your channel, thank you

[arianzarei]

Thank you for your great and high quality video. It actually helped me correctly arm and setup my Brushless Motor after two days of searching the internet and watching many low quality youtube videos.

Thanks for posting this! I'm going to build an Outlaw Pinewood Derby car for our pack's race this month and I'm using a 50mm brushless ducted fan. This tutorial got me up and running so I know my gear is good, I still need to figure out how to incorporate a switch on the nose of the car so it knows when to switch from idle to wide open when the start gate drops but this gets me started! Thanks again!

Been searching for 2 weeks to find an explanation to this. And I’ve found it. Thank you so much!

This is a fantastic explanation, and it lends itself to the point that a brushless DC motor effectively replicates a 3-phase ac motor except with a permanent magnet rotor. Complete with three 2-pole coils that are activated out of phase with one another. Great stuff!

iam doing an arduino project for my uni studies involing an rc boat and you helped me very much thank you man! Gonna watch the transmitter video too.

[Grzzs]

You do such a great job of making your videos informative enough but not loaded down with too much information! Keep up the great work!

I am working on drone from past 1 week, what a timing man for this amazing

[fabbarrs]

This is the BEST video I have ever seen. It will help A LOT in my graduation conclusion project. Thank you!

[nemdenemam]

hands down the best video (or even lecture) about BLDC motors.

One (possible) problem: arent the directions of the magnetic field wrong at 0:35 in the coil? If that image were right then there would be bi directional magnetic field inside the coil. If the N -S are right, then the open field lines are right, while the closed loop field lines are wrong.

[mustielhans]

Thank u,
that was the best explanation that i have every heard

That means the brushless motor is in fact a symchron ac motor

[electrouino]

I’ve been looking for a video like this for ages, thanks, this is so useful

[christiannagy]

This video pretty much contains everything about bldc motors. Nice Video!

[bobm]

A very well made vid. Had to play 3 times because I got hung up on his accent. Very good explanations and a lot of information. Have a bit to catch up ! Thanks, Bob

100 pts to this video. I'm an electronics engineer I can't find something wrong with it. Very good
