4. Applications:
Computer controlled stepper motors are a type of motion-control positioning system. They are typically digitally controlled as part of an open loop system for use in holding or positioning applications.
In the field of lasers and optics they are frequently used in precision positioning equipment such as linear actuators, linear stages, rotation stages, goniometers, and mirror mounts. Other uses are in packaging machinery, and positioning of valve pilot stages for fluid control systems.
Commercially, stepper motors are used in floppy disk drives, flatbed scanners, computer printers, plotters, slot machines, image scanners, compact disc drives, intelligent lighting, camera lenses, CNC machines and, more recently, in 3D printers.

Related Qualification Certificate:
Stepper motors are the preferred choice in ultra-high vacuum applications, such as vacuum precision positioning stages and actuators. Parts like encoders, sensors, and electronics, which are required to operate servo motors, are missing here and will neither contribute to outgassing nor be destroyed during high-temperature bake-out procedures. When operated in open-loop, the digital nature of stepper motors eliminates position jitter, or oscillations, that can be caused by poorly-tuned servos.
