Product Overview

1.8 or 0.9 Degree 2 Phase NEMA 23 Electric Hybrid Stepper Motor

This hybrid stepping motor converts electrical pulse signals into precise angular or linear displacements. It is an ideal solution for high-precision applications requiring reliable torque performance (0.48n.M - 3n.M).

  • High-grade SH level magnetic steel for stable performance.
  • Coated rotor to reduce burrs, ensuring smooth operation and low noise.
  • Rigorous step-by-step testing for stator and rotor components.
  • Versatile application in 3D printers, CNC machines, textile machinery, and automation equipment.

Frequently Asked Questions
What is the difference between a 1.8° and a 0.9° step angle?
A 1.8° step angle means the motor takes 200 steps per revolution, while a 0.9° angle takes 400 steps. The 0.9° motor offers higher resolution and precision with smoother rotation, while the 1.8° motor typically handles higher speeds better.
Can the NEMA 23 stepper motor be customized?
Yes, we support customization for shafts, lead wire lengths, and integrated components such as gearboxes, encoders, brakes, or integrated drivers to meet specific project requirements.
What applications are best suited for these motors?
These motors are widely used in CNC milling machines, 3D printers, medical equipment, laser engravers, textile machinery, and various automation systems requiring precise positioning.
How is the quality of the rotor and stator ensured?
We use high-grade SH-level magnetic steel. Both the stator and rotor undergo individual testing before assembly, followed by a final comprehensive performance test of the completed motor.
What certifications do your stepper motors hold?
Our products are compliant with international standards, holding certifications including ISO9001, CE, RoHS, SGS, and REACH.
What lead wire options are available?
Depending on the model and application needs, motors are available in 4, 6, or 8-wire configurations to support various wiring schemes like bipolar or unipolar.
