[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 ...

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 ...

TMC2209 is a stepper motor driver chip from German firm Trinamic that I suspect folk interested in the insides of 3D printers will be hearing a lot more about in the near future. In many printers, the ...

[TBJ] is building what he calls a junkbox 3D printer. You can probably guess that he’s trying to salvage most of the parts for the device, and after pulling a stepper motor from an old printer he was ...

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, ...
