That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed Control (ESC). [Fileark] built and ESC using an Arduino and has a couple of posts ...

In this case, they’re being used to create a basic PWM motor controller. The trick is to ... used as easy-to-build dimmer switches, too.

grbl is stepper motor controller firmware for three-axis cnc machines ... that are too powerful for the normal drivers included on grbl Arduino shields (or integrated Arduino+drivers equivalents), and ...

Permanent magnet dc motors need a chunky inductor ... engineering was to do two things: get this controller and motor running again, and then add an electrically-safe interface to allow remote control ...
