Frequently Asked Questions

Q: Does this mini stepper motor include a driver board?

A: No, a dedicated stepper motor driver board is required for operation and is not included with this motor. Ensure you pair it with a compatible 2-phase 4-wire stepper driver for best results.

Q: What is the output speed of this DC 5V stepper gear motor?

A: At a rated voltage of DC 5V, the original motor runs at approximately 790 RPM. After the 1:150 gear reduction, the output speed is approximately 5.3 RPM, making it ideal for slow, high-torque precision applications.

Q: What are the typical applications for this stepper reduction motor?

A: This motor is widely used in projector lens focus mechanisms, smart shared locks, precision laboratory equipment, DIY robotics, and small automation systems that require accurate and repeatable positional control.

Q: How do I identify the correct wiring for this 2-phase 4-wire motor?

A: The wire color code is as follows — Blue & Black wires correspond to coil A (A+, A⁻), while White & Red wires correspond to coil B (B+, B⁻). Connect these to your stepper driver board accordingly.
