Hybrid Mini Stepper Motor Nema8 20mm Unipolar Step Motor 180g.cm
300g.cm
Stepper motors are known for their accurate positioning
capabilities and high torque delivery at low speeds, but they
require careful sizing to ensure the motor matches the load and
application parameters, to minimize the possibility of lost steps
or motor stalling. Adding a gearbox to a stepper motor system can
improve the motor’s performance by decreasing the load-to-motor
inertia ratio, increasing torque to the load, and reducing motor
oscillations.

5. 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.
