We’ve looked at Carl Bugeja’s PCB motor several times since he started work on it over five years ago. His innovation was to ditch the wrappings of copper wires that make ordinary motors too heavy, and to embed that functionality in a PCB. It’s enabled him to create brushless motors that are smaller and lighter, and he’s even branched out into the field of flexible PCBs to create different types of actuators.

The latest iteration of the Bugeja PCB motor features an upgraded speed controller, enabling the tiny electromagnets to turn on and off faster than before to achieve a top speed that’s now 30,000 rpm faster than his previous model. We’re in awe of Carl’s dedication to this project, and we can’t wait to see what he comes up with next.
