[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 ...

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.
