Product description of encoder connector  stepper motor

  1. Accurate position Control

    The angular displacement of the stepping motor can be precise controlled by the number of electrical pulses.Angle accuracy can be controlled within ±0.09°without any feedback devices.

  2. High reliability, easy maintenance.Motor rotor structure accurate, no loss of step.Rotor special material, not stuck machine.

  3. Longer Life

    Stepping motor is a mechanical structure,which does not need be changed by electric brush or Hall sensor,thus reducing the probability and increasing the motor life.Stepping motor life usually determined by the life of the bearing.

  4. Strictly control the production of parts to improve the quality of parts

  5. The Fulling product line is sold to major manufacturing Companies for Industry of automation, medical andhealth care equipment, printer machine, packing device,Information Technology,household appliance,product, AGV and automobile.

Encoder connector stepper motor Application


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.
