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
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!
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.
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 :)
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)
Fährst du 1:5er oder warum hast du den Toro Beast Motor? Würde mich allgemein mal interessieren ob du auch im Modellbau tätig bist? Schönes Video, mach weiter so :)
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!
+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...
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.
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.
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!
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...
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
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!
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?
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
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
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
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
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.
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.
Dear Scott Hopefully you get to read this message. Ive seen in most videos that bldc motors are powered with lipo batteries, surely because of the discharge rate of the battery. I am new in the subject but I would like to test bldc motors powered with an adjustable dc power supply rather than lipos. My question ir regarding the current. Most 100EUR Lab PS outputs only 10A and 0-30V 100A PS costs more than a 1000EUR. Will I burn my PS when the motor is loaded or at start? I am missing something here? Are batteries in consecuence the cheapest way to power bldc motors? I hope you can help me out here or if you could clarify this in a video would be awesome!! since I believe there is nothing concrete about this in youtube. Keep it up! Ich habe vor 2 Jahren in BW studiert. Ich wusste nicht, dass wir praktisch Nachbarn waren xD 70372.
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
I wanted to power custom cooling fan for my room. I have a large 20cm wooden model propeller. I just don't know what kind of engine to choose from. I have small brushless from a model plane and a DC motor from RC car. Which one is better for this application? Should I get AC motor for stationary work? Can you even power brushless motors without batteries but through some kind of AC/DC charger?
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
Can you explain what you are doing with the joystick around the @3:50 part of the video? I know that joysticks like that use 2 or more potentiometers and I've played with one in that capacity by hooking it up to a home made speaker as well as a simple led circuit, but the resistance was far too high for either of those circuits so it mostly served as an on/off switch...
Really liked how you approached explaining motors, hope you continue to do educational vids like this
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
I have not enough money to buy a rotary tool but you gave me a cool idea that I use to make a rotary tool......
Best electromagnetic brushless motor analysis.
the best results that I have ever had was by using the Gregs Electro Blog (i found it on google) definately the best info i've followed.
i just can't get enough of your videos
That brushless motor is insane.
Great video! I appreciate the disassemble of the motors and the demo. The video worth a thousand words. Thank you!
This is great. I'm currently making a project with some old HDD's and ive been fiddling with the circuitry for a while, this really helped thank you!
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!
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.
Definitely, Best video Series. Please make more like this!
A Video about Nixie Tubes would be great !
This video has been very clear and understandable, thank you......
Awesome video as always. These videos are very useful (especially for a beginner like me).
My nigga Scott is back at it again.
Ty scott Please keep making videos
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 :)
like your explanation the most.. continue posting videos. please try to build a quadcopter and post the video
You are friggin awesome! And I like your slight accent, makes you sound badass
Thanks mate ;-)
So i finally know how my RC car works! :D
Thank you Sir!
English sounds good
God bless.
Another great video! I really enjoy your videos and appreciate how much time and effort you put into making them. Keep it up! :)
nice video. adios amigos
+Proyectos LED Con que vos tambien lo ves ? Jajajaja
I like the new intro.
could you make a video about building a simple rf transmitter and receiver with an explanation of how it works. You explain everything so easy :D
Great Scott!
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)
I knew I stockpiled old dvd drives for a reason!
You're Intro is so cool!
أتابع قناتك و أنت مبدع
Okay, I'm hooked. Fun stuff.
Sir you are awesome....
Fährst du 1:5er oder warum hast du den Toro Beast Motor? Würde mich allgemein mal interessieren ob du auch im Modellbau tätig bist? Schönes Video, mach weiter so :)
Finally back after a week
My favourite shop HK, so is yours I noticed
Nice explanation in all videos
Now I know how it is driven, maybe I could make my own ESC using the MSP430 and a few FETs
Very nice and informative video. Could you perhaps also do a similar video on high-power LEDs and constant current drivers?
+vidm96 I did a basics video video about led already. And you can find a design to a constant current source in my HACKED! Laser video.
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!
Can you make a video on the reverse process... like a wind powered dynamo to capture useful energy - maybe charging a battery?
+Peter Lane it's the same thing. when you do the reverse it is called "electromagnetic induction" if you want to look it up.
you need a 3 phase diode bridge to convert it to dc.
+Sirus six diodes
+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...
you say 'series' but it sounds like 'serious'😂 btw ...your videos are better than awesome! and i am your Indian Subscriber!
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.

Wow excellent video, thank you for shearing!
Love the new intro
You aesome m8! Can you please from now on put links to conrad purchases too? They are handy for your dutch/german viewers
+daniel tabrizian I don't like conrad. I stick with Ebay or Amazon.
you can easily purchase from ebay and amazon in those country's
+Lukas Noels (LN2S) not if u dont have a credit card
GaMMaLiKKeR who buys from the internet without a credit card?

that's a real nice explanation! can you build a stabilizer with the brushless motors and make a tutorial of it?
This helped me alot with my electric scooter project :D
please make a video on how to design Electronic speed controller for brushless DC motor
TY. Very good video
great video, but could you make a video about measurment equipment a begginer would need
+Aleksa Stipanovic I put it on my to do list.
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...

Excuse me Sir, how can I support you in Patreon? Your videos are great and I like you to make more for us electronics hobbyist :D
Please visit his channel, About .. click on 'support me for more videos' .
There is also a link in every video description.
GreatScott!
is that True that your brushless motor has more than 7000 w for me sound this unrealistic
Stefan Bramel
Stefan Bramel yes that's true there is also higher kilowatt ones the have like 10hp they are like 8kw but with a mutch higher voltage like 60 or 70v
ive got a brushless motor in my rc car but I never knew how it worked thx
3:16 .. oh flux capacitator... 1.21 gigawats!? great scott! :D
Excellent
awesome video my dude.
Your speed calculation for the switching frequency, depends on the pole pairs.

Where do you connect the positive and the negative current feed?
and where does the yellow control wire for the windings connect?
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
Awesome Bro...
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
Make a video about inverter
this something i have been trying to figure out for a while. how do you hook up a joystick to control circuits
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
Thx for a nice video humbre keep up.
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 do an electronics basics video on transistors?
+ali10163 Already on my to do list.
+GreatScott! thank you
great video!
Would you consider making one about constructing an ESC, or using arduino to control a brushless motor (if that is possible)? Thanks.
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
Can you detail the brands/models of components, software, and tools used?
Please, do a tutorial to logic gates.
+Borda Czech Already on my to do list.
great video
James R estte
can you talk more about esc ???? I mean making video about it !
Great 👍 video
Will you make a vedio on homemade brushless motors and esc's
so what's the difference between synchronous AC motors and brushless DC? I guess the DC motor doesn't receive any negative currents
Great video!
What is the difference in application between stepper motors and the brushless ones?
Hey why do you not used the beast motor for your longboard because it has a ideal kv rating and 6000watts would be great for hills
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?

Will you make a video on how to make a simple ESC?
can you make a video on how to make a drone?
+Kyle C It is already on my to do list.
+GreatScott! Omg yes.
ditto
Would it be possible for you to make a video that explains very clearly how esc work and maybe building one yourself?
Felix Blaquiere bro go buy one they literally cost 15 dollars for a waterproof one
Silly question but if I wanted to learn about all things electronic should I pursue an electrical engineer degree? or are there other pathways?
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.

+Banterinatoor 420 It's already on my to do list.
Where doas the Power for the Arduino comes from? Can I connect it to the Batterysystem from the ESC or did I have to use a 5V Signal?
can i run a brushless motor without using the yellow wire? i'm lost on the yellow wire...
great stuff, keep up the good work. For a project idea try to make an LED light bulb with built in Bluetooth speaker
