Such an amazing video !! Thanks for this masterpiece. AN Electronics engineering student here , it is really helpful. I always had to rely on buying motor drivers, now I will get started with making my own. :)
This is such an excellent tutorial Max! I've been on the verge of jumping in deeper into electronics and this is easily the most intuitive and easy to follow video I've come across. So good! Thank you sir 🤘
Thank you for creating such an amazing video! I’ve learned a great deal from it. As an electronic engineering student, your videos constantly remind me why I’m so passionate about electronics.❤
Awesome max! I must say you got into the Diy electronic teaching properly haven't seen you make such a video on diy electronics components, great job and more wins bro
One of the best video i have seen ever, now i can say i know how brushed ESC work or even I can make it own with very few components. Thank you so much max! For Making such informative video in simplest way😊 keeping come up with awesome videos 👍
Hey, Jonu. Super glad to hear you found my video helpful as an RC enthusiast! Thank you! I look forward to seeing how you apply this knowledge in your future RC projects... :)
Wow, it’s a great video, the provided explanations are clear and detailed enough allowing to understand how it works and the purpose of each components. The troubleshooting section provided in the video makes it even better, you nailed it, you got a new fan my friend!
Omg. This is probably the best video ever to come across for diy ESCS! Its so easy to comprehend and understand even the fact that you aren't using any fancy schmanzy pcbs but just standard perf board anyone can get is even more helpful! Micro escs are such a hassle to find this is just wonderful ^^ Great work! Is it also somehow possible to drive the bi-directional esc with only 1 signal line just like a off-the-shelf esc to use with a RC receiver?
This is really great video.. and I had been searching this in your drone videos.. which you spoke to watch your videos of making motor drivers.. Thank you
Loved the circuit, LOVED the PCBs, and thankyou for explaining what parts you used and what alternate parts might be helpful. Great little masterclass on motor drivers you've made! :D
If you are like me (not as good at sub-pitch protoboard soldering) you might want to use TA6586 driver. It can handle A LOT of current for it's size (10A max, 6-7A continuously in dip-8 package). I use it everwhere even if space is not a constraint as it's specs are amazing and price is rather low
Great video and very well done explained. I will have a go at creating the bidirectional H bridge motor driver for my rc model train in HO scale. Thank you again and great job. 👍
MOSFET datasheets commonly state 10V for Vgs under test conditions. If driving under this, check "drain-source on-state resistance (Rds-on)" figures. e.g. for the Si2300DS, it's typically 0.070 ohms at Vgs = 2.5V, Id = 2.6A. Note these figures can vary across parts. If only Vgs = 10V is listed under test conditions, then the MOSFET most likely won't work well at 3.3/5V (most likely overheat due to high Rds-on), and an additional driver/~10V power supply would be required to use. You can use DigiKey's/Mouser's search filters to find a suitable part.
hello! I see that you're reading the comments on your channel. I watch your videos in Russia and I am very grateful to you for creating high-quality subtitles in different languages. Thank you for that. But the name of the video in Russian sounds strange. I'm ready to help you with translating the video title into Russian, if you want.
I suspect that a driver like this would burn itself out quickly, since it doesn’t have any space for cooling / a safety factor for current draw. That’s just my intuition though. How resilient are these mini motor drivers? How long can you run them continuously? And have you had any issues with them burning out? This is still an incredible video, and a hugely useful DIY. Thanks Max 🙌🔥
Hi there. I have had zero problems with these motor drivers in terms of power handling. The drivers may get a tiny bit warm after some use with TT motors with 180 brushed motors for example, and those are powerful motors. If you need to, a heatsink can always be added to the PCB drivers, but these don't get hot if operating the right motors. These are very reliable and resilient, you can run them continuously for hours if you wanted to with the motors of the correct ratings I displayed. Thanks for watching!
Very well prepared, documented and narrated video. Thank you for all of these. I have 3 questions for H-Bridge drivers. 1- What types of components you recommend to use 10-24V power supply considering the most of the mosfets have 20VGS values. 2- Is there another way (I mean using solid electronic components - hardware) to control the timing between the direction changes as you stated that the MCU has to have a delay of around 20ms. 3- Can you provide the Truth Tables as well as I wonder if the H-Bridge drivers supports the "BREAK MODE" that is applying the voltage at the same time to the signal sides. Thanks again! :)
Hi and many thanks for your comment! To answer your questions: 1 - The SI2304 (N-channel) and SI2303 (P-channel) come in as a great MOSFET alternatives for the H-bridge as their drain-to-source voltages is 30V. 2 - Aside from code changes, you can add a RC (Resistor-Capacitor) delay circuit to the gate drive of your MOSFETs. By placing a capacitor in parallel with a resistor between the gate and ground (or gate and source for N-channel MOSFETs), you create a time delay for charging/discharging the gate. This will naturally introduce a delay in switching states, effectively mimicking a 20ms direction switch delay without needing code. Choose values for the resistor and capacitor that result in the desired RC time constant (τ = R × C), where τ determines the delay. For example, a 10 kΩ resistor and a 2µF capacitor will create a 20ms delay. 3 - If you want active breaking applied to your H-bridge, you'll need to remove two crossed signal connections that turn 4 transistor bases/gates to only 2 inputs, leaving you with 4 inputs from the NPN transistors and N-MOSFETS. You apply breaking my turnining on both of the low-side (N) MOSFETs ON. It will go like: Forward: One high-side and one low-side MOSFET are ON. Reverse: Opposite high-side and low-side MOSFETs are ON. Brake: Both low-side (or high-side) MOSFETs are ON. Coast: All MOSFETs are OFF (motor freewheels). Hope this answers your questions! :) Max
Hey max this was a very great project. So I am also trying to make a similar type of motor driver so I want to make a rc plane so can I drive this motor drivers directly from the pwm signal of a flysky reciever?
Hi Max - you probably didn’t see it - but I made a motor driver which mounts onto an N20 motor’s brushes, essentially allowing it to take up no space. I’m not sure how much you use N20 motors, but if you’d like some of the spare driver boards I have, I’d be happy to send some over for free if you’d like to test them 😁 Love your content as always 😊
Hi. Thank you! You can, but you don't need to make the scaled up version as the tiny MOSFET Unidirectional driver can handle driving it (8520 motor) - and it's lighter too.
@@MaxImagination I am really interested to know from where did you learn to code these microcontrollers. As I am a rookie,it would help me a ton to bring my ideas to life
Hi there. Sure, you may proceed with the enlarged version of this driver following the same schematic. I learned to code by watching courses on Skillshare and reading books. One book I recommend is "Beginning C for Arduino"
Very nice and helpful, also it would be so great if you created a community like maybe in discord or telegram where people can talk and discuss there builds and the problems they face
Very cool video! But if you are going for miniaturization, why use discrete mosfets at all? There are H-bridges as small as 2x2mm (with enough current capacity). If you want hand-solderable package, there are options in the same sot23 package as a single mosfet. I used DRV8837 and CJDR9111 in my 1/87 scale RC models, and they work pretty well. There are also dual h-bridge options that are even more space efficient (e.g. DRV8835). What's more, these dedicated h-bridges have over-current and over-temperature protection, which mosfet solution lacks.
Thank you! However I believe you missed the point! I made motor drivers with the least components possible anyone can make even on a perf board to have bare minimum driving control. With the DRV8837, you cannot solder it onto a perf board. Thanks for recommending me an alternative. It's still good to keep in mind.
@@MaxImagination Yeah, if perfboard is a requirement, then QFN package is not the best choice, but a SOIC will probably suit well and still be smaller than 4 mosfets. (and I've seen a guy on youtube who solders QFNs to a 1.27mm-pitch perfboard upside down, it's mind-blowing)
This is cool! If we want to connect this esc directly to the receiver pwm pin, what IC do we need to add? Most of the micro dc esc that we bought online have their IC label scraped off.
Thank you! In most cases, you won't need an IC to drive these motor drivers with a standard RC receiver if it has PWM. Simply connect the PWM output pins to the inputs of your custom driver. However check your receiver is not using PPM, which would probably then need conversion.
@MaxImagination but most receiver will output servo PWM that's different from regular PWM. I'm curious about their 'secret' 8 pin IC that received servo PWM and output regular PWM. Lol
Thanks max, very good work, will come in handy. Nice of you to answer so many comments, thanks. Different perspective below: What if the work is to have only one motor spin at a time? Could we have a different MCU for every motor? Then every MCU listen to a different I2C id? What if we drive one small motor directly out of two (or 4) MCU port(s)? Arduino ports around 20 mA per port but MCU: PML100 200 mA per port Is that possible? and is that MCU cheaper than the cost of a driver ? Can this 5 cent 8-pin MCU drive 4 (or 2) small DC motors ? OR one small stepper? Is that very low cost solution, worth going to mini-c and $60 ICE (to save retry time?)
Since flyback currents happen for a VERY short duration, it can handle the instantaneous current unlike if it were to be continuous. Yes, they're rated for 1.5A, but they work just fine.
Nice Video. Thanks! I'd like to control the Motordriver with an RC Receiver (PWM signal with 50Hz but only a Signal-on-time between 1.5 and 2.5 milliseconds) Is there a was using discrete components to use the Receiver and your motordriver?
@@MaxImagination I was looking for a mini transistor for a touch button to control a powerful LED. You saved me time searching for this transistor in such a case, thank you very much
I still don't have the platform created for you to learn what I know, maybe in the future. But I learned from books, watching UA-cam videos, and magazines.
I just found your channel with the self-centering steering mechanism video. I was about to make an h-bridge with transistors but there wasn't any protection diodes in the example i used. So I guess i can see how long this circuit lasts then come back to this video. Do you not do any 3D printing? I'm about to make the self-centering steering mechanism using laser cut wood and nylon filament. I like how your technique in making these tiny boards. I'm making my transistor h-bridge on a 3018 cnc, I wonder if I could make the smd version with protection diodes on a single sided pcb?
Hope you find this knowledge applicable in your project! Yes, I do 3D printing too as you can see from my other existing videos. If you want to instead 3D print the steering mechanism, you can actually find it integrated in my 3D printed version or the PVC RC car that uses it - via buying its 3D files here in case you consider it: cults3d.com/en/3d-model/game/3d-printed-rc-car-with-steering-under-20-3d-modeled-pvc-car-design Nice little CNC machine! With the right tool on the end, you probably could even make the SMD H-bridge I showed in the video. Sure! But make sure you know if it's possible to add Via-in pads to your custom made PCB. My design uses vias.
It good and.. everything ...but why not just buy a 8pin microchip that has even 2 chanel full gate switching...???.. (i know that ic but i dont remember the ic name)
Not many people can salvage such IC from old boards in a junk yard. If you're looking for one with an IC, it's better to simply buy the complete module.

Yes, it's pretty much the same at the SI2300.
Thank you I asked for it and u made it
You're welcome :)
what did you use to simulate the circuit at 4:07?
I used Falstad - Circuit Simulator
@ 4:00 the 1N4148 will not handle the amps as a freewheel diode, or am I mistaken?
Since flyback currents happen for a VERY short duration, it can handle the instantaneous current unlike if it were to be continuous. Yes, they're rated for 1.5A, but they work just fine.
Nice Video. Thanks!
I'd like to control the Motordriver with an RC Receiver (PWM signal with 50Hz but only a Signal-on-time between 1.5 and 2.5 milliseconds)
Is there a was using discrete components to use the Receiver and your motordriver?
why do you use diode T4? in mosfet already integrated diode
The T4 diode is a fast-switching diode. The diode in the MOSFET is not. It's for an extra layer of protection.
Can I use as a brushed esc
by any chance do you have a video about how to do a voltage regulator?
(need like 5v for a rc receiver to match with the custom-made esc's)
I don't have a video on that yet. You can get voltage regulator ICs like the LM78XX series.
Use the LM7805 in your case.
with which marking do you use transistors?
I didn't understand your question. Please clarify. I show what transistors I use in the video.
@MaxImagination Sorry, I didn't notice it in the video, I must have missed it, I found it in the description under the video, thank you!
@@MaxImagination I was looking for a mini transistor for a touch button to control a powerful LED.
You saved me time searching for this transistor in such a case, thank you very much
Glad I could help. Awesome!
What is soarce learning thiese type idea please share with me
I still don't have the platform created for you to learn what I know, maybe in the future. But I learned from books, watching UA-cam videos, and magazines.
I just found your channel with the self-centering steering mechanism video. I was about to make an h-bridge with transistors but there wasn't any protection diodes in the example i used. So I guess i can see how long this circuit lasts then come back to this video.
Do you not do any 3D printing? I'm about to make the self-centering steering mechanism using laser cut wood and nylon filament. I like how your technique in making these tiny boards. I'm making my transistor h-bridge on a 3018 cnc, I wonder if I could make the smd version with protection diodes on a single sided pcb?
Hope you find this knowledge applicable in your project!
Yes, I do 3D printing too as you can see from my other existing videos. If you want to instead 3D print the steering mechanism, you can actually find it integrated in my 3D printed version or the PVC RC car that uses it - via buying its 3D files here in case you consider it: cults3d.com/en/3d-model/game/3d-printed-rc-car-with-steering-under-20-3d-modeled-pvc-car-design
Nice little CNC machine! With the right tool on the end, you probably could even make the SMD H-bridge I showed in the video. Sure! But make sure you know if it's possible to add Via-in pads to your custom made PCB. My design uses vias.
are you stalking me? because i was just planning on making a mikro drone
either way, i love you too
Glad to hear you found this guide useful for your micro drone!
i thank you for the video, but i have a question, what app do you use for your drones and RC?
Subbed!
from where can i buy these spools of tiny components
From the link in the video description. Please see the materials list for each and you'll find where to buy the spools.
It good and.. everything ...but why not just buy a 8pin microchip that has even 2 chanel full gate switching...???..
(i know that ic but i dont remember the ic name)
Not many people can salvage such IC from old boards in a junk yard. If you're looking for one with an IC, it's better to simply buy the complete module.
I have a ss14 diode, can it be used as a replacement for the ones in the video?
Yes, this diode can work too.
ขอบคุณมากครับกับสาระดีๆ
You're welcome! Glad I could help :)
bro which engineer group want to study for this type of work
in which school did you study? can I get admission there? i'm almost 50~
I come from the school of experience. Experience and action is the best teacher. I learned from Books and UA-cam videos and applied what I learned.
any thoughts on making a discord channel?
Not at the moment, but I'll consider it in the future! Cheers. 😊
@@MaxImagination pls do so 😭🤲😂 a community for young minds to come together led by u is great. I'm literally alone I need a study partner or mentor 😅
Working on it :)
Excelente trabajo. Gracias
❤❤❤🤔
О, на катушечке с обмоточным проводом надписи по-русски детектед.
Such an amazing video !! Thanks for this masterpiece. AN Electronics engineering student here , it is really helpful. I always had to rely on buying motor drivers, now I will get started with making my own. :)😁
Awesome to hear - good luck with your projects! Thanks!
Im finding videos like this ngl HAHHAHA.thanks
Happy to help!
