Driving 3-phase brushless motors with Arduino

Following from our previous article about the home-made three phase electric motor, we have now a new three-part (or phase?) tutorial on how to drive three-phase brushless spindle motors that are found in old CD/DVD drives. The authors have described more than one method of doing so, and also explain how to use a SN754410NE motor driver IC as well. Finally after several demonstrations the tutorials culminate with the design of a stroboscope – a rotary form of animation shown below:


So for the full run-down on brushless motor control, click here. And we’re on twitter and Google+, so follow us for news and product updates as well.


When making your own motor controllers, you’ll need a protoshield to mount the external circuitry. In doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega range, we offer a complete range for you to work with.
