15mm Linear Screw Stepper Motor 123mm Stroke for 3D Printer DIY
15mm Linear Screw Stepper Motor 123mm Stroke for 3D Printer DIY
15mm Micro Linear Screw Stepper Motor – 123mm Stroke Slider for 3D Printers & DIY Projects
Upgrade your CNC machine, 3D printer, or precision automation project with this compact 2-phase 4-wire 15mm micro linear screw stepper motor. Featuring a generous 123mm slide stroke and a precision lead screw, this stepping motor delivers accurate, repeatable linear motion in a remarkably small footprint — perfect for DIY builds where space and precision matter.
Unlike conventional rotary motors, this stepper converts rotational motion directly into controlled linear displacement via its integrated lead screw and slider nut, eliminating the need for separate mechanical linkages. Whether you're building a custom 3D printer axis, a camera slider, a micro-robot, or a lab automation fixture, this motor gives you the precise step control you need.
⚠️ Important Note: This is a stepper motor — it will not spin when connected directly to a power supply. A stepper motor driver board and control board (e.g., Arduino, Raspberry Pi, or dedicated CNC controller) are required for operation.

Frequently Asked Questions
Q: Can I connect this linear stepper motor directly to a 12V power supply to make it run?
A: No — stepper motors require a dedicated stepper motor driver board (such as an A4988 or DRV8825) and a microcontroller (such as an Arduino or CNC control board) to generate the proper step and direction signals. Simply applying DC voltage will not cause the motor to rotate or move the slider.
Q: What is the maximum linear travel distance of this stepper motor slider?
A: The slide stroke of this micro linear screw stepper motor is 123mm, with a lead screw length of 143mm and a fine pitch of 0.6mm per revolution for high-precision positioning.
Q: Is this 15mm linear stepper motor compatible with standard 3D printer control boards?
A: Yes. The 2-phase 4-wire bipolar configuration with NHS-4Y terminal connector is compatible with most standard 3D printer and CNC driver boards. Ensure your driver is configured for the correct voltage range (9–15V DC) and current limit to match this motor's phase resistance of 15 ohms.
Q: How does the voltage setting affect performance of this stepper motor?
A: Within the 9–15V operating range, a higher voltage increases driving force and speed but also increases heat generated by the motor. For sustained operation, it is recommended to run at a moderate voltage and use a driver with adjustable current limiting to balance performance and temperature.
