engraving machines, embroidery machines, wire-stripping machines,
terminal crimping machines, hosiery machines, textile machinery,
computerized flat knitting machines, food machines, packaging
machinery, stage lighting, winding machines, industrial printers,
3-D printers, medical equipment and etc., in particular, the
customers comment well upon the newly-produced servo motors with 10
poles, due to their attributes of higher precision, lower low-speed
pulse, higher RPM, more superior features of servo, as well as
lower vibration and less noise.
Hejie Motor has a number of senior staffs of design and development, in
addition of the manufacturing capacity of toolings and moulds for
motors’ production, also eagerly expects to exploit some special
electric motors by joint-efforts with the customers.
2phase NEMA17 25A 0.65NM HYBRID STEPPER MOTOR FOR 3D Printer
Stepper motors consist of a rotor with permanent magnets and a
stationary stator that carries the windings. When current runs
through the stator windings, it generates a magnetic flux
distribution that interacts with the magnetic field distribution of
the rotor to apply a turning force. Stepper motors feature very
high pole counts, typically 50 or more. The stepper motor driver
energizes each pole in sequence so that the rotor turns in a series
of increments, or steps. Because of the very high pole count, the
motion appears to be continuous.

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.
