Stepper Motor (NEMA 17) — High-Precision Motion Control

The NEMA 17 stepper motor is a versatile, high-precision actuator designed for projects that require accurate position control and reliable torque. Available in 40mm and 48mm heights, this bipolar 4-wire motor delivers stable performance for 3D printers, CNC machines, robotics and many automation tasks.

Key Features & Benefits

  • High Precision: 1.8° step angle (200 steps per revolution) gives repeatable, fine-grained positioning for accurate prints, cuts and motion profiles.
  • High Torque: Robust holding torque suitable for demanding applications where steady force is required.
  • Compact Form Factor: NEMA 17 frame (42mm x 42mm) in 40mm or 48mm stack height — fits most common mounting patterns and tight assemblies.
  • Bipolar 4-Wire Wiring: Simple 4-wire interface for compatibility with popular stepper drivers (A4988, DRV8825, TMC2208/TMC2209, etc.).
  • Low Vibration & Noise: Designed for smooth operation to improve print quality and reduce mechanical resonance.
  • Durable Construction: Metal housing and quality internals for long service life under continuous or intermittent use.

Specifications

  • Motor Type: Bipolar stepper motor (4-wire)
  • Step Angle: 1.8° per step (200 steps/revolution)
  • Frame Size: NEMA 17 (42mm x 42mm)
  • Available Heights: 40mm and 48mm
  • Wiring: 4-wire (bipolar) — compatible with standard stepper drivers

Compatibility & Recommended Drivers

This NEMA 17 motor works with common stepper motor drivers and controllers. For best results pair with microstepping drivers like A4988 or DRV8825 for basic applications, or silent microstepping drivers such as TMC2208/TMC2209 for low-noise CNC and 3D printing setups. Compatible with microcontrollers including Arduino, Raspberry Pi (with a driver) and other motion controllers.

Mounting & Installation Tips

  • Confirm mounting holes and shaft orientation before assembly — NEMA 17 uses a 42mm x 42mm faceplate pattern.
  • Adjust motor current on the driver to match your motor’s rated current (check motor label/spec sheet) to avoid overheating.
  • Use microstepping for smoother motion and reduced resonance; enable appropriate decay mode on drivers when required.
  • Secure mechanical couplings and shafts to prevent slippage; check alignment on pulley or lead screw systems.

Typical Applications

  • 3D printers (X/Y/Z axes, extruders)
  • CNC routers and milling machines
  • Robotic arms, pan/tilt and automation mechanisms
  • Camera sliders, gimbals and precision positioning systems
  • DIY electronics, makerspace projects and educational kits

40mm vs 48mm Height — Which to Choose?

  • 40mm: Compact option when space is limited or when lower torque is sufficient.
  • 48mm: Taller stack typically provides higher torque — choose for heavier loads or higher holding requirements.

Why Choose This NEMA 17 Stepper?

With its precise 1.8° stepping, robust construction, and low-noise operation, this NEMA 17 stepper motor is an excellent choice for hobbyists and professionals alike. Its bipolar 4-wire design makes it easy to integrate with popular drivers and controllers while the two available heights (40mm and 48mm) let you balance torque and size for your project needs.
