Editing Stepper motor (section)

==Applications==
Computer controlled stepper motors are a type of [[motion-control]] [[positioning system]]. They are typically digitally controlled as part of an [[Open-loop controller|open loop]] system for use in holding or positioning applications.

In the field of [[laser]]s and [[optics]] they are frequently used in precision positioning equipment such as [[linear actuator]]s, [[linear stage]]s, [[rotation stage]]s, [[goniometer (positioning)|goniometer]]s, and [[mirror mount]]s. Other uses are in packaging machinery, and positioning of [[valve pilot]] stages for [[fluid control system]]s.

Commercially, stepper motors are used in [[floppy disk|floppy disk drives]], [[image scanner|flatbed scanner]]s, [[computer printer]]s, [[plotter]]s, [[slot machine]]s, [[image scanner]]s, [[compact disc]] drives, [[intelligent lighting]], [[camera lens]]es, [[Numerical control|CNC machines]], and [[3D printer]]s. Some programming hobbyists have used arrays of stepper motors as [[electronic musical instrument]]s by programming the motors to rotate at the frequencies of different musical tones, in a sequence that imitates that found in a [[MIDI]] file.<ref>{{cite web | url=https://www.youtube.com/watch?v=-yEuYGodNLo&list=PLkY8-UOMZQ0_S1d5x9e6bpIRV-4yxKlLx | title=Yakety Sax - Stepper Motor music | website=[[YouTube]] | date=20 March 2016 }}</ref><ref>{{cite web | url=https://projecthub.arduino.cc/JonJonKayne/arduino-midi-stepper-synth-162864 | title=Arduino MIDI Stepper Synth }}</ref>
