PCB Motor Holds Fast, Even After 1.6 Billion Spins

If you aren’t up to date with [Carl Bugeja]’s work with tiny brushless PCB motors, his summary video of his latest design and all the challenges it involved is an excellent overview. Ba…

High Caliber Engineering On A Low Torque PCB Servo Motor

Building a 3D motor printed motor is one thing, but creating a completely custom servo motor with encoder requires some significant engineering. In the video after the break [365 Robots] takes us t…

What Makes Wedge Coils Better Than Round For PCB Motors?

PCB motors are useful things. With coils printed right on the board, you don’t need to worry about fussy winding jobs, and it’s possible to make very compact, self contained motors. [at…

Single Flex PCB Folds Into A Four-Wheel Rover, Complete With Motors

You’ve got to hand it to [Carl Bugeja] — he comes up with some of the most interesting electromechanical designs we’ve seen. His latest project is right up there, too: a single PC…

Laser Scanner Upgraded To Use PCB Motor

[Rik]’s Hexastorm laser scanner project originally used a discrete polygon mirror controller+motor module from Sharp to spin a prism. But the scanner head was a bit difficult to assemble and …

Exploring The Hall Effect For Haptic Feedback PS4 Joysticks

Modern gaming console controllers aren’t without their annoyances — Joy-Con drift, anyone? The problems might stem from design deficiencies, but we suspect that user enthusiasm and the …

A Fast Linear Actuator Entirely In One PCB

There are many ways to make a linear actuator, a device for moving something is a straight line. Most of the easier to make ones use a conventional motor and a mechanical linkage such as a rack and…

Tiny PCB Motor Robot Is Making Its First Wobbly Moves

[Carl Bugeja] has been working on his PCB motors for more than three years now, and it doesn’t seem like he is close to running out of ideas for the project. His latest creation is a tiny Blu…
