NEMA23 1.8 degree 57mm hybrid stepper motor 2 phase stepping motor
Which types of stepper motor is divided into? - 1.Stepper motor is divided into three types: permanent magnet
stepper motor (PM), variable reluctance stepper motor (VR) and
hybrid stepper motor (HB).
- 2. PM stepper motor is generally 2-phase, with small torque and
volume, its stepping angle is generally 7.5° or 15°.
- 3. VR stepper motor is generally 3-phase; high torque output can be
realized; the stepping angle is generally 1.5, but the noise and
vibration is large. The rotor magnetic circuit of VR stepper motor
is made of soft magnetic materials. There is multi-phase exciting
winding on the rotor. The torque is generated by taking advantage
of the change in magnetic conductance.
- 4. HB stepper motor, indicating mixing the advantages of PM and VR,
is divided into 2-phase, 3-phase and 5-phase. The stepping angle of
2-phase is generally 1.8°, that of 3-phase 1.2° and that of 5-phase
is 0.72°. It is mostly widely applied.
Description of 57mm hybrid stepper motor - 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. High reliability, easy maintenance.Motor rotor structure accurate,
no loss of step.Rotor special material, not stuck machine Online testing of technical parameters to ensure the consistency of
data product parameters Forward/Reverse Rotation,Pause and Hold The forward /reverse rotation of the stepping motor can be
controlled by the input sequence of the controlled electric pulses. 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.

NEMA23 stepper motor Application InformationComputer 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. |
