NEMA17 Stepper Motor Mini (40mm)

Nema17 4.2 kg-cm Single Shaft Stepper motor can provide 4.2 kg-cm of torque at 1.7A current per phase. The stepper motors move in precisely repeatable steps, hence they are the motors of choice for the machines requiring precise position control.

The motor’s position can be commanded to move or hold at one position with the help of Stepper Motor Drivers. The Nema17 4.2 kg-cm Stepper motor provides excellent response to starting, stopping and reversing pulses from stepper motor driver.

They are very useful in the various application, especially which demands low speed with high precision. Many machines such as 3D Printers, CNC Router and Mills, Camera Platforms, XYZ Plotters etc.

It is a brushless DC motor, so the life of this motor is dependent upon life of the bearings. The position control is achieved by a simple Open Loop control mechanism so doesn’t require complex electronic control circuitry.

The motor’s shaft has been machined for good grip with a pulley, drive gear etc. and especially avoiding stall or slip.

Technical Specifications:

  • Model: 17HS4401-22B
  • Shaft size: 5mm
  • Rated Voltage: 12V DC
  • Current: 1.2A at 4V
  • Step Angle: 1.8 deg.
  • Stepper Motor Height: 40mm
  • 200 steps per revolution
  • Operating Temperature: -10 to 40 °C
  • Unipolar Holding Torque: 22.2 oz-in
  • Input pulse decides the rotation angle of the motor.
  • High accuracy of around 3 to 5% a step.
  • Provides good starting, stopping and reversing.
  • Control of this motor is less costly because of the exclusion of complex control circuitry.
  • The speed is proportional to the frequency of the input pulses.

Applications:

  • 3D printer/prototyping machines (e.g. RepRap)
  • CNC machines
  • Precise control machines
  • Laser cutters
  • Pick and place machines

Package Includes:

  • 1 Piece– NEMA17 Stepper Motor Mini (40mm)
Weight 300 g
Dimensions 40 × 40 × 50 mm

Wiring Instruction

Wiring Guide

1. Power Supply

  • A4988 VDD → Arduino 5V
  • A4988 GND → Arduino GND
  • A4988 VMOT → External Power Supply (+12V or +9V)
  • A4988 GND (next to VMOT) → Power Supply Ground

2. Control Pins (Arduino → A4988)

  • STEP → Arduino Digital Pin 3
  • DIR → Arduino Digital Pin 2
  • ENABLE (optional) → Arduino Digital Pin 8 (can be left unconnected for always enabled)

Wiring Guide with Diagrams to Interface with Arduino and A4988 Motor Driver

3. Motor Coil Connections

The NEMA17 motor has 4 wires (two coils):

Motor Wire A4988 Pin Description
Coil A1 1A First end of Coil A
Coil A2 1B Second end of Coil A
Coil B1 2A First end of Coil B
Coil B2 2B Second end of Coil B

4. Capacitor

Place a 100 µF capacitor across VMOT and GND near the driver to prevent voltage spikes.

5. Adjusting Current Limit

Use the small potentiometer on the A4988 module to set the current limit for your stepper motor to avoid overheating.

A4988 / TMC2209 Wiring Guide

This is a standard 4-wire bipolar stepper motor. For optimal performance with A4988 or TMC2209 drivers, connect the wires as follows (always verify with a multimeter for continuity):

  • Coil A: Black (A+) and Green (A-)
  • Coil B: Red (B+) and Blue (B-)

Pro Tip: Set your driver VREF to ~0.75V–0.85V to safely supply the rated 1.5A per phase without overheating.

Torque Curve & Performance Notes

Holding Torque: 4.2 kg-cm (at 1.5A/phase)

Detent Torque: 38 mN.m

Performance Note: Like all hybrid stepper motors, torque decreases as RPM increases. To maintain maximum torque at higher speeds, pair this motor with a 24V power supply and a stealthChop-enabled driver (like the TMC2209) to reduce resonance and heat buildup.
