NEMA 17 Stepper Motor - 1.8° Step, 0.45Nm, Bipolar
NEMA 17 Stepper Motor - 1.8° Step Angle, 0.45 Nm Holding Torque
The NEMA 17 stepper motor is a widely used bipolar motor with a 1.8° step angle (200 steps/revolution) and a holding torque of up to 0.45 Nm. It is a staple in precision motion control for desktop CNC machines, 3D printers, and small robotic platforms. Its standard NEMA 17 frame ensures compatibility with common brackets and mounting plates.

Compatibility
This 4-wire bipolar motor pairs with A4988, DRV8825, or TMC2209 stepper drivers. It runs on 12-24V DC and works with Arduino or Raspberry Pi via driver boards. Commonly used in RAMPS 1.4 and similar controller setups.
Wiring Notes
Connect the four wires to driver outputs A+, A-, B+, B-. Use a step stick with microstepping enabled. Keep current below 1.5 A to avoid overheating; active cooling recommended above 1.2 A.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, with a stepper driver like A4988 or DRV8825. Connect the driver to 12V and Arduino digital pins for step/direction control.
What power supply do I need?
A 12V DC supply rated at 2A or more is sufficient. For higher torque at speed, 24V may be used but ensure driver supports it.
Does it come with a connector?
Wires are bare; you can solder to a 4-pin JST XH connector or directly into driver screw terminals. Standard 4-pin dupont female housings fit.
