Why does a Brushless motor (BLDC) have 3 Wires

- Brushles motors are quite complex in how they operate. The speed control is completing thousands of functions per minute just to keep up with all the action. 3 Wires on a Brushless motor are necessary, but why? Hint - the wires purpose is changing many times per second and does not stay constant.

Thank fuck! I’ve been scrolling CZcams for hours trying to figure out how to power a motor that I bought! Thank you!
NOW I understand what happened when I put power on one wire of my Ebike hub motor. It briefly spun then stopped immediately. Because the current was stuck at one place. Thanks for the lucid video.
Glad it helped
I FINALLY got what the fuss was about the back EMF. Everywhere I read back EMF was used to calculate the speed, but only now I am getting how it is actually done. Thankyou!
glad it helped
@@RCexplained I came back to this today, and I think there is something wrong with the diagram. Idk how to explain this in a short comment, but when i tried to draw a diagram of this, I couldn't really decide the winding direction of the coils because they have to keep changing according to this diagram. Sometimes clockwise and sometimes counter-clockwise. I think the terminals need to be at 120 degrees from each other.
Simply explained!😊
Thanks, I learned something today! Good explication for understanding!
Glad it was helpful! Thank you for your wonderful feedback!
This is a fantastic explanation. You would be great in a classroom. Thank you
Thank you I enjoyed learning the 3 phase wires makes sence now
Gracias por la informacion me quedo muy claro tenia la idea que un cable era señal Saludos desde Chile
Very useful video, thanks!
Glad it was helpful!
Nice explanation, cheers for making it.
Thank You!
Brushless motors will save the world 🌎
thx
Glad you found the video helpful
I’m just trying to figure out if I can retrofit a brushless motor into my starter box, and what it would require to do so. If it can be done at all. My engines have such high compression the standard two 7.2v batteries cannot turn the flywheel. So I need to know what to do with the third wire? Do I need a small esc? Can I wire it like a brushed motor and run the 3rd wire to elsewhere? I am fairly, no, completely lost with the new brushless motor workings. Help!!
You will need a brushless esc
Wow, this could have been SO much simpler with a simple animation or slideshow!
I'll have to learn how to do animations as I have no clue. Thanks for the comment
@@RCexplained nah, the video was awesome. I can get a book or a slideshow anywhere, i like hearing from a person who knows what i want to know.

I admit, I'm coming in as someone who knows very little about brushless motors, but it would make a LOT more sense if C1 and B2 had the same polarity and B1 and C2 had the same polarity. If they do, the magnet would stop when it is pointing at A1 and A2 and that would trigger the pole reversal causing it to flip again thus rotating, but if it was really the way you have it drawn, the magnet would stop halfway between B1 and C1 on one side and halfway between C2 and B2 on the other side. I'm just going to assume you messed this up since what you are saying doesn't really make any sense.
Have you ever seen anything like this!..👉 czcams.com/video/cheU-HHe16c/video.html
Why bosch drill 10.8v li model have only 2 wires out? But it is brushless
Most DC motors are this way, with a simple positive and negative to spin the motor, reversing the polarity to go the other way. I believe the speed is modulated via decreasing the voltage. Not really sure the specifics of windings, but it's a continous, simpler version of the BLDC one in this video.
The thumbnail and right illustration is definitely just wrong, as can been seen in the signal graph of the 3 wires
Yep, this only happens for a split second once every rotation.
How much should I praise for this would be less
Internet Said It Doesnt Matter How You Wire Your Brushless Motor. Just Flip 2 To Reverse Rotation. This Video Explained Why It Doesn't Matter. Cus All Widings End Up Alternating Thier "Jobs"
That's correct!
Is there any 2 wires BLDC motor is available in market? If yes, give me brief explanation how it was possible?
An alternator might be a brushless dc motor.
A fan motor might be a brushless dc motor.
The motor speed is synchronous to the ac frequency.
By controlling the frequency of the AC supply, you control the speed of the rotation. A variable frequency drive “vfd” is used as an electronic speed controller (esc).
Can such a motor be converted to a generator
All motors can generate power.
No body has done this
thanks
i have lost a bet with my mate now
Uuuuummmmm... So which wire is positive and which wire is negative.?
You can reverse the phases
This is a great example of a counter effective you tube piece of knowledge. The details are all wrong or ambiguous at best. The three terminals explained as (+), (-) and (digital pulse) are simply wrong and overwhelmingly disappointing.
In the beginning was the Word, and the Word was with God, and the Word was God. 2He was with God in the beginning. 3Through him all things were made; without him nothing was made that has been made. (John 1:1-3)
We didn't need an explanation how it works, all we asked was, what they are for, simple.
