What is a Stepper Motor? All About Stepper Motors @ The Adafruit Learning System.

Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called “phases”. By energizing each phase in sequence, the motor will rotate, one step at a time.

With a computer controlled stepping you can achieve very precise positioning and/or speed control. For this reason, stepper motors are the motor of choice for many precision motion control applications.

Stepper motors come in many different sizes and styles and electrical characteristics. This guide details what you need to know to pick the right motor for the job.

  1. Hi!

    Nice article. Could be great you can cover here also where we can find free or cheap stepper motors (i.e. old printers or photocopy devices) as stepper motors are quite expensive. Thanks!
