Abstract: This paper describes a bang-bang controller which, with a particular novel scheme of discrete-state variable instrumentation, operates the stepping motor as a digital servo. The near ...

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 computer-controlled stepping, you can ...

A stepper motor, also known as step motor or stepping motor, is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can be commanded to move ...
