We have some important news to share about HackSpace: Issue 81 was the last issue of HackSpace as a standalone magazine, and HackSpace has become part of The MagPi, the official Raspberry Pi magazine. Starting with issue 145, We’ll be adding pages to The MagPi to make room for the stories and tutorials you’ve come to expect from HackSpace.

This open-source PCB motor is a small, cheap, and easy-to-assemble micro brushless motor. What’s unique about this motor design is that the stator is printed on a four-layer PCB board. The six stator poles are spiral traces wound in a star configuration. Although these coils produce less torque compared to an iron core stator, the motor is still suitable for high‑speed applications.
Creating a brushless motor using a PCB is cheaper to manufacture, and allows the designer to easily tailor the design to their specific project. This design is lighter than standard brushless motors, which opens up countless opportunities for smaller, more delicate projects.
Carl Bugeja, the motor's creator, has a YouTube channel detailing how it works, and you can get the design file on it's Hackaday.io page.
