Intro: Make Your Own ESC

In this project I will firstly demonstrate how a common ESC works and afterwards create a circuit consisting of an Arduino Nano, an L6234 motor driver IC and a couple of complementary components in order to build a DIY ESC. Let's get started!

Step 1: Watch the Videos!

The two videos give you a good idea of what is necessary to do to create your own ESC. In the following steps I will present you some additional information.

Step 2: Order Your Components!

Step 3: Create the Circuit!

Here you can find the schematic along with reference pictures of my board layout.

Step 4: Upload the Code!

Here you can download the code that I created for the project. Since I created quite a few of them you can download them all.

Sketch 1: Uses the analogRead function to measure the current

Sketch 2: Uses the external interrupt on pin 3 to measure the current

Sketch 3: Uses timer 2 to control the current chopping

Sketch 4: Uses the interrupts on pin 10,11,12 to switch to the next step

Step 5: Success!

You did it! You just created your own ESC!

    this driver is only for brushless motor, brushed motor is a completely different structure and you cannot modify from this driver

    hi, i have a quick question about this design, if im using Sketch 4 can i remove everything between pins 14 and 17 on the motor controller and pin 3 on the Arduino, the reason i ask is that i am limited on size in my current project

    Hello...i've been trying to make esc based on your project, i already downloaded your arduino's code but i couldn't create the sketch and since i'm still learning in arduino, so i want to ask you about your code in your video, does that video show the full code of the project?

    Sorry for my bad english.

    Hello! Is it possible to implement a digital speed reference? Without using a potentiometer.

    Great instructable, but I think there are a few errors in your schematic. The RC filters you have on the comparator inputs look to be drawn incorrectly. The capacitor should be located directly on the comparator pin, so that the capacitor forms a voltage divider along with the resistor, to form a lowpass filter. As drawn, the capacitor is right across a low impedance source, so it will have little to no effect.

    Awesome project! We made it exacatly like you.. The only problem is that the motor isn't spinning fast enough. Do you have any idea why this is happening? We using the software 4.ino

    Very nice! How about a high res version of the schematic that I could actually read? That would be much appreciated.

    Left click on the image, left click again and select the resolution on the left side. You can even print it as a poster.

    nice job without Fet module , however I was wondering if you've had any research for using the high power IGBT module and its pre driver to control large BLDC motor using in electric car, any advise really appreciated
