An Open Source ESC For Brushless Motors

For something basic like a brushed DC motor, speed control can be quite simple, and powering up the motor is a simple matter of just applying voltage. Brushless motors are much more demanding in their requirements however, and won’t spin unless driven just right. [Electronoobs] has been exploring the design of a brushless speed controller, and just released version 1.0 of his open-source ESC design.


The basic design is compact, and very similar to many off-the-shelf brushless ESCs in the low power range. There’s a ..
