[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 ...

[ZeroBacklash] created a little strain wave gearbox (harmonic drive) for when you want to trade speed for torque on NEMA 17 stepper motors. Strain wave gears work by deforming a stationary ...

Stepper motors are DC (direct current) electric motors designed for precise motion control. They consist of multiple sets of coils and magnets which are designed to allow rotor movement in angular ...
