[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

It’s little secret that stepper motors are everywhere in FDM 3D printers, but there’s no real reason why you cannot take another type of DC motor like a brushless DC (BLDC) motor and use that instead.

The AMIS-30521 and AMIS-30522 stepper motor driver ICs allow engineers to eliminate the need for switches, Hall sensors, flyback diodes, and many passive components in applications ranging from ...

Stepper motors are inexpensive and rugged because they have fewer mechanical parts. They are brushless, easy to position, and are commonly used in automation systems, although they are small low power ...

You might think that CD players and DVD players have had their run, but as it turns out, they are absolute goldmines for DIY projects. Pop one open and you'll find stepper motors, laser assemblies, ...
