Safety Information
Warning: Failure to follow these safety instructions may result in damage to the motor, driver, or other components, and may pose a risk of injury.
- Always connect the stepper motor to a constant current or chopper driver. Connecting the motor directly to a power supply will destroy the motor.
- Ensure the driver's output current does not exceed the motor's rated current (2A).
- Ensure the driver's voltage does not exceed 36V.
- Carefully verify the four wire coil order when connecting to the driver to prevent damage to the driver.
- Avoid touching the motor during operation as it may become hot.

Setup and Connection
Wiring Diagram
The motor comes with a 1-meter cable and a 4-pin Harwin female connector. The wire colors correspond to the motor phases as follows:
- Black: A+
- Green: A-
- Red: B+
- Blue: B-
Connect these wires to your stepper motor driver according to the driver's specifications. Ensure correct polarity and phase assignment to prevent damage.
Mounting
The motor features a 42x42mm frame with standard NEMA 17 mounting holes. Use appropriate M3 screws (maximum depth 4.5mm) to secure the motor to your application's frame or bracket. Refer to Figure 3 for detailed mounting dimensions.
Operating Instructions
Once the motor is securely mounted and correctly wired to a compatible stepper motor driver, follow these general operating guidelines:
- Driver Configuration: Configure your stepper motor driver's current limit to match or be slightly below the motor's rated current of 2A per phase.
- Voltage Supply: Provide a DC voltage to the driver within its specified range, ensuring it does not exceed 36V. Higher voltages (within the driver's and motor's safe limits) can improve high-speed performance.
- Step Control: Use your control system (e.g., microcontroller, CNC controller) to send step and direction signals to the driver. The motor will move 1.8 degrees per step.
- Microstepping: Utilize microstepping features of your driver for smoother operation and reduced resonance, especially at lower speeds.
Maintenance
The STEPPERONLINE Nema 17 stepper motor is designed for long-term, reliable operation with minimal maintenance. Consider the following:
- Cleaning: Keep the motor free from dust and debris, especially around the shaft and mounting surfaces, to ensure smooth operation and proper heat dissipation.
- Inspection: Periodically check wiring connections for looseness or damage. Ensure mounting screws remain tight.
- Operating Temperature: Ensure the motor operates within its recommended temperature range. Excessive heat can reduce motor lifespan. If the motor becomes excessively hot, reduce the driver current or improve cooling.
Troubleshooting
- Motor Not Moving/Erratic Movement:
- Check all wiring connections, especially the phase order (A+, A-, B+, B-). Incorrect wiring can cause erratic movement or prevent rotation.
- Verify the power supply to the driver is adequate and stable.
- Ensure the driver's current limit is correctly set for the motor (2A).
- Check for mechanical obstructions preventing motor rotation.
- Motor Overheating:
- Reduce the current setting on the stepper motor driver.
- Ensure adequate ventilation around the motor. Consider adding a heatsink or fan if operating in a high-load or enclosed environment.
- Verify the load on the motor is not exceeding its holding torque capacity.
- Lost Steps/Inaccurate Positioning:
- Increase the driver current (up to 2A) if it's currently set lower.
- Reduce the acceleration or maximum speed settings in your control software.
- Check for excessive mechanical friction or binding in the system the motor is driving.
- Ensure the step pulse width from your controller is sufficient for the driver.
