Stepper motor drive circuits
Stepping out...



To date, I've just seen three simple circuits for driving unipolar or bipolar stepper motors:

  • Wilf Rigter's NuStepper -- uses just a single IC ('though not one you're likely to have in your "parts box") to give you reversible motor drive

  • Solarbotics Nv-based Circuit-- uses a single IC (and it's a common one, too -- the 74AC240) to give you motor drive in a single direction

  • Duane Johnson's BEAM Stepper -- based on a single 74AC240, gives reversible motor drive.

Then of course, if you want to cheat, ICs specifically made to drive stepper motors are commercially available as well.
