Danke für die Erklärung. Endlich habe ich das Kommutator Equivalent verstanden und den Grund warum die Dinger nicht schon länger überall aufgetaucht sind. Danke :D
Very good video I always take time to watch them is a very good information thank u for keeping us informed sometimes i forget and I watch the videos and I keep going on with my projects.
Hey scotr, a small correction. I have built my own BLDC controller for a 1kW motor. The PWM is what determines the speed of the motor not the frequency. The frequency is a byproduct of the PWM. That being said keep up the good work!
Your videos are superb :) No academese ("the flux cutting is propprtional to the cross product of the lagrangian transformation which as will be obvious on inspection is the second order differential equation of mah butt"), engaging style which is fun to listen to, and obviously a huge amount of knowledge behind it all :)
+Zooty The Duck - Is it? So when you spin a brushless DC motor you'll get useful current out from the ESC? I don't think so ;-) So I'll rephrase my question - perhaps a video on using a brushless motor as a generator etc.
+Sirus ok that makes more sense - but wind does not blow at a constant speed so something would need to account for high and low voltages... now I'm stepping outside my limits...
I was searching for this a few hours ago... Awesome speed delivery my friend! What's your secret? I was digging up brushless motors from my bin literally 3 hours ago :D (ps. the KV value means RPM/Volts, e.g. KV100 is at 400 RPM at 4 volts)
Can you explain more about the ESC's and brushless motor? like what ESC should we get to get that reverse brake and forwards functionality that was shown in the software as well as how is the signaling works with all those modes and what determines the motor features in terms of KV rating max current and power ect physically.
Man! Where do you get all of this equipment from? Please make a separate video showing each of your Lab Equipment and from where to buy them. That will be great!
hey buddy thanks again, could you do a video on electro magnetics (think I typed that rigt?) I would like to start a project that I want to add a electro magnet to serve as a lock for a hidden shelf thing I seen here on the boob tube made by "the king of random" I believe, the only people whos I could think to ask was yourself and "the post apocalyptic inventor" by the way you guys should do a segment together maybe like a head to head battle to make something (you both make the same thing but in your own unique way) made from scrap electronics, you guys are inspiring a whole new generation of inventors and entrepreneurs, you may not realize but by posting these videos you could be directly guiding the life of our newest potential geniuses keep up the good work and keep educating the world!
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!
And how about doing your own ESC, not bought one? Doing lightweight ESCs should be pretty challenging engineering task. Keeping motor perfectly synced at higher RPM, with soft start, active breaking, changing direction and without luxury of hall sensor is something I would like to see in a video.
i really love your channel... really learned alot of stuff from you.. could you make a video about power supplys? i dont know how to connect more devices to one supply...
can you explain more in depth of how torque works using a impact gun because using a standard drill would not work explain how it gives more power then regular drill
can you make a small winch with the brushless motor and a pulley system with it i think it would be a cool video if you lift some weights with the motor
Hi, Thanks for this video. It's definitely helpful. I'm trying to build a 3 axis gimbal for my camera and wanting to use the brushless motors for it. What would you recommend for something like that. Or if u can make a video about making a 3 axis gimbal
is there a way to make a setup to both test the motors and the ESC's of quadcopters? what would be the best way? what would be the cheapest way? Great content
Brushless ESC systems basically create a tri-phase AC power output of limited voltage from an onboard DC power input, to run brushless motors by sending a sequence of AC signals generated from the ESC's circuitry, so wrong title,,
great video bro,quick question would stacking mosfets on my ESC work to make it more resistant to burning and would it make the motor stronger?thank yoy
Jesus Christ: well I just made a 3D printer from scratch, and only used internet for the ramps board connections for the rest just knowledge and I am right handed
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?
Hello. very informative video! normal 3-phase AC motors are actually just "brushless motors" so it would be theretically possible to build an esc that such an motor operates. am i wrong? I think it would easier and cheaper then a frequenzy converter. Mach weiterhin solche Videos! viele Grüße aus Bayern
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.
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
Hi, I was wondering if you could use a esc to control a stand fan motor, it’s because I have one laying around and wanted to see if this could work, I’m a little bit confused because it has 8 coils and 4 wires, do I connect the main 3 to the esc and the last one that is divided into two are supposed to be connected with a capacitor? I want to see if I could controlled it with a dc supply, even though the output of the esc is Ac, but you get the point. If this couldn’t be done what else I can do to make it work, thank you. 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.
