8mm Micro Linear Stepper Motor 5V 2-Phase 4-Wire Screw Actuator
8mm Micro Linear Stepper Motor 5V 2-Phase 4-Wire Screw Actuator
8mm Micro Linear Stepper Motor – Precision Screw Actuator
This compact 8mm 2-phase 4-wire micro stepper motor delivers precise linear motion in an ultra-small form factor. Running on DC 5V–6V, it's ideal for DIY electronics projects, miniature robotics, optical lens positioning, camera autofocus mechanisms, lab instruments, and any application requiring highly controlled linear displacement.
Key Features
- Compact 8mm body – fits easily into tight spaces and miniature assemblies
- 2-Phase, 4-Wire design – compatible with standard stepper motor driver boards and microcontrollers (Arduino, Raspberry Pi, etc.)
- Precision screw drive – converts rotary motion to smooth, accurate linear displacement
- Slide stroke: 29.5mm (1,900 pulses) for reliable, repeatable positioning
- Low power draw – phase resistance ~21.8Ω; short-circuit current at 5V: 0.21A
- Smooth operation – best driven with medium-to-low frequency pulse signals; recommended driver current: 0.14A
- Ultralight weight – approximately 5.2 grams, minimizing load on delicate assemblies
- Low voltage operation – below 50Vac / 75Vdc, EU LVD compliant

Frequently Asked Questions
Q: What voltage should I use to operate this 8mm micro linear stepper motor?
A: This micro stepper motor is designed to operate at DC 5V–6V. For smooth, reliable linear movement, drive it with medium-to-low frequency pulse signals and set the driver current to approximately 0.14A to prevent overheating and ensure precise positioning.
Q: How much linear travel does this screw stepper motor provide?
A: The screw slider provides a total slide stroke of 29.5mm, achieved over 1,900 motor pulses. This makes it well suited for applications requiring fine, repeatable linear displacement in a compact space.
Q: Is this stepper motor compatible with Arduino or Raspberry Pi?
A: Yes. The 2-phase, 4-wire configuration is widely compatible with standard stepper motor driver modules (such as the A4988, DRV8825, or ULN2003) that work seamlessly with Arduino, Raspberry Pi, and other common microcontroller platforms.
