[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 ...

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 ...

Stepper motors and servomotors both belong to a class of motors designed for precise position control. Steppe r motors are brushless DC motors that move a rotor in small angular steps or fractions of ...
