Electronic Basics #18: DC & Brushless DC Motor + ESC
video description
By the way, the wiring I mention is something I think it could work from videos and wiring that I have seen, but not 100% sure.

Great great video I learned quite a bit but my question is. where do the actual wires connect inside the coils of the brushless motor? if there's no Plug-In or color-coordinated I only have three wires coming from ESC theres 3 wires that got ripped out but the black is still connected inside the coils somewhere. how or where do I reconnect or solder the 2 remaining wires that got pulled out? Thanks it's a dji mavic pro

Your speed calculation for the switching frequency, depends on the pole pairs.
Calculation: electrical angle / pole pair = mechanical angle
Your big PMSM has 4 poles (N+S, N+S) so 2 pole pairs therefore the factor 2
The small motor, PMSM has 7 pole pairs so 14 magnets inside, right? ;)
The fact with the KV story is correct!

Can you make DC genrater with brush less moter if yes, so what the winding is it? I have many brush less moter and trying to made genrater and also looking on internet but I didn't find any thing and then I remember you can help me. So plz help me I am waiting for your help you are my last hope

What kind of bench power supply would be appropriate for running a bunch of BLDC motors? Like 81 motors each rated for a max 10amp with 30amp esc. I have a project I want to try building but I would rather not use batteries since this is a stationary project that would be used intermittently.

Hello, I see in the video, you have a switch connected to a board and a speed control. I am want to do the same thing. I want to be able to vary the rpm with a speed pot and then trigger it with a low voltage momentary contact switch, Is this an arduino board? or something else?

Im a little confused.
So its a star winding with a centre tapping.
Where do you connect the positive and the negative current feed?
and where does the yellow control wire for the windings connect?

Excellent video. I have a problem, when I speed up fast my motor using the joystick it turn down like if it lost the power as a cut. I set it like you. is it the ESC or motor. please?

Hi! i have a brushless dc motor force feedback game wheel. I want to add a second identical motor for more strength. Is this going to put double the stress on my circuit board?
