This was the video I was waiting for a year or more... now lets get a 4 channel version of that :) Thanks for your great work.

[@luisbangueses]

@electronoobs Estoy usando un modulo arduino nano en lugar del integrado Atmega 328p. Luego de bajar el scketch D2 queda configurado como entrada y no como salida CL. Alguna sugerencia? Estoy usando la version ESC_BEMF_v3_3

[@RajaKhan-tf6ks]

Sir can you make a video on electronic full course

[@FrozenPieces909]

Hey Electra noob I’ve been trying to redo your ECS that you posted I bought all the components and follow your instructions to the tea I cannot burn the boot loader the FTDI does not work the Arduino does not work neither does the nano I’ve tried everything can you please reply and tell me what’s needed so I can proceed the atmega 328AU chip will not burn I cannot troubleshoot it all the instructions that she put everybody is having the same problem they can’t burn the boot loader what is it that you did to get that boot loader to burn because it just won’t burn

[@FrozenPieces909]

Please give detailed instructions List all require parts software and Hardware programs needed to complete the steps. I want the esc for a diy brushless hub motor I made and I’d like to test it bc the other escs aren’t big enough to step my 18p12n motor

[@hardikmonga]

you are the only electronics diy youtuber who also explains the things with proper animation. APPRECIATE YOUR WORK MAN, ITS FAB!!!!!!!!!!!!!

[@wowfail6835]

You released this video literally just as I was about to go on summer break from university. My "summer" project is to design an 80A ESC for a long board BLDC motor, thank you so much!

[@h3Xh3Xh3X]

We are trying to design an open source ESC for 100v at forum.electricunicycle.org if you're interested. :)

[@spirit1484]

hey, so i’m trying to do this exact project, making an esc for an electric longboard. Is this esc design sufficient for the larger motors that are used in eboards, or are modifications necessary for those higher currents?

[@wizzardofwizzards]

Using the different colors for the illustrations was a great way of presenting the theory and operation. Great work!

[@youpattube1]

Good video and good explanation of an ESC and a brushless motor.

[@kyrk55]

You can always use buzzer with generator or use one phase of motor to make noise.

[@kaden56]

Perfect timing! I have been looking for an esc for a robotic arm and I wanted it to be arduino friendly!

[@joemwiti2316]

This is really great job. I enjoy your videos, the explanation is on point. Keep it going mate.

[@wardprocter2371]

Great video Electronoob, I learned a lot as usual. I really think the board layout needs a banana hidden somewhere on the silkscreen layer. 😀🍌

Thanks, you have made my job a lot easier, I want to make a small 10A esc and this is a great starting point

[@TechInventorAman]

10:07 How are you able to program the chip via ftdi breakout without burning the arduino bootloader first . As far as i know without the bootloader you can only program avr via spi bus

[@ELECTRONOOBS]

The IC already has a bootloader. I've used a chip from an Arduino nano. If not, you will have to burn a bootloader first. Thanks

[@TechInventorAman]

@@ELECTRONOOBS you haven't told that in the video i recommend you should do that as it will avoid confusions

Nice job ! A extra feature or idea for a new project would be to use those motor as alternator to get energy, and best of all to be able to switch beetween using as a motor or use to get energy back while breaking.

[@vincentsteinmetz3726]

Using the back emf to switch as the right time and to get the energy back very efficiently.

[@SIKHGT650]

@@ELECTRONOOBS mate why 5v regulator is not used instead of buck converter?

[@ELECTRONOOBS]

@@SIKHGT650 because usually ESCs will also supply the radio receiver, other elements and some servos in case of an RC plane for example. A normal LDO can't give enough current so we need a buck converter. In this case could give around 2A.

[@nlieske]

Could you make a 75v 300a version of this?

[@vonries]

Great job as always.

[@northshorepx]

Wow - impressive work.

[@myetis1990]

great job friend, in order to get rid of calibration we can implement dshot600 protocol instead of pwm dutycycle. most of esc of drone motors are using dshot because of reliability. therefore, i think that if your esc supported the dshot then it would be great.

[@mwagner1996]

Wow, you sure put Great Scott's ESC to shame. Great work!

[@minayoussef7227]

What is the (f) of the big capacitor??

[@georgepaidakis9450]

Congratulations for this great project. I want to ask you what modifications need to be made to the esc so that the input voltage is 50 V and the current 30 A.

[@dhanrajrayannavar3443]

What is the current rating of this esc?

[@thegoynextdoor]

The current rating of the ESC per phase would be the current rating of the MOSFETs, I would assume

[@budianto-1650]

on changing the step, how to decided if the BEMF will rising or falling ? For example, changing step from AH_BL to AH_CL, why expect BEMF_B_FALLING, not BEMF_B_RISING ?

[@dizzyworld22]

The code from the ZIP-file dated 06/07/2019 is using different pins than the current board V2 uses. It burned me 2 MOSFET drivers and 4 MOSFETs. The old code does work though.

[@rizqokarim7093]

why you choose buck converter instead of voltage regulator? arent it more simple? i really want to know, thankyou

[@alexzirnea]

Great project, but if you want more current at the motor, I'd suggest to do some via stiching on the power tracks, a single via just can't handle that much current when going from a side to another.

[@ELECTRONOOBS]

Yes, version 2 has big via and exposed tracks so you could fill that with solder. Thanks!

[@Quantum_Dots]

How to make this bidrectional ESC , so motor can rotate front and back

[@caslor2002]

Great work - project as always !! Thanks for sharing this... Hope you consider to make code version that would have and backward rotation (for the moment i haven't look to your code to see if it is easy to be modified for that option) thanks again

[@Andre_Beth]

Nicely done, I think I will give this a try. Have you done any work on FOC (Field Oriented Control) which I believe is more efficient because it makes use of all three phases simultaneously? I think that would be an awesome project for all of us to follow (the ultimate ESC). I know that it may be a lot more difficult, but to have a super smooth running almost noiseless motor would be awesome. It would definitely get me to join your patreon list. Cheers and thanks for the awesome videos.

[@mohanjadhav2297]

as always amazing..... genius!

[@donaldwright2426]

Thanks for this video. I intend to use your base design. I need a higher voltage, more than the 12Vdc. I will separate the hi voltage (60 to 144Vdc) of the powerFET of the gate drivers from your the 12Vdc. It should be an easy change. And I will try to have this board work with FOC sinewave. Great job!

[@plermpelng1379]

What rpm does this ESC theoretical reach?

[@Beredro]

The single via on your main power tracks is the hero of this video...maybe you should add some more or this PCB will not last very long

[@ELECTRONOOBS]

In the final design the via is big enough so I could fill it with solder. Thanks!

[@joelmate9403]

How can you do to spin the motor in the other direction? Thanks!

[@seddikkhamlichi]

Hello Can you give the diagram file for adding some modifications? Thank you!

[@fungaimudzengelele6532]

Can you please share the Gerber file for the remodeled board. Thank you

[@davidtlchow]

It is better to separate the controller circuit and driver circuit, so that higher power applications can be used without considering the size of the controller board. Simple mosfet driver boards are easy to make but with the cost of the mosfets. Maybe possible to add code to include a regenerative braking suitable for EV applications?

Can we make powerful ESC (200A+) with Arduino ?

[@_who_cares_1123]

For the USB to Serial converter I would recommend the CH340E not the CH340G. It is smaller, cheaper and doesnt need a crystal oscilator.

Integrated comparator. The Atmega328 chip has a comparator on pin D6.

Bhai esc ko jlcpcb me banao na bhai 😢

[@nghiakhac6530]

where is the EMF measured in circuit?

[@jmibk]

Does anyone got this esc to work? I ordered the pcbs and the parts and it doesnt work. Main problem is that the board draws over 1 amp from the 12v supply without the motor connected. It seems to be a problem with shoot through of the halfbridges. The mosfets and its drivers get very hot - also with and without the motors. I got some defect mosfet drivers as well. The board and the circuit works itself, I tried with a demo sketch generating 3 square waves with the 3 halfbridges and everything works. The code from electronoobs does nothing than beeping at high frequencies and heating up the components.

[@casianb1]

hi. The comparator pins are subjected to AC voltage (positive but also negative). They are not rated to negative voltages. Why didn't the arduino die? Is it because you enable the comparator inputs only when the voltage is positive?

[@nurullahaydin3048]

Very nice video, thank you for your work. I want to ask something. Can this ESC control a motor with 60 A?

[@Randomaccountxd530]

nice work, but can you please make the code to work with RC car controller(make the motor go both ways, forward and backwards)?

[@dmitrynuzhdin]

Great video, but I think you did a huge mistake in BEMF explanation: the zero-crossing happens in the middle of floating phase, not at the end. At 7:17 you said that we should switch phases exactly at zero-crossing, but no! We should detect zero crossing and wait about the same time that passed from phase start to zero-crossing!

[@nufgorf]

Would it be possible to reprogram the esc to be reversable? Such an ESC would be useful for robotics, being able to spin the motor both directions. Current reversable/programable ESC's are quite expensive. And I have been subscribed for ages, but I missed this episode.. now I have to go through and see what other ones I missed!
