DC 3V Mini Linear Actuator Planetary Stepper Motor | Screw Slide
DC 3V Mini Planetary Stepper Motor with Linear Screw Slide Actuator
This compact DC 3V Mini Linear Actuator combines a 2-phase 4-wire stepper motor with a precision planetary gear reducer and a ball-bearing-tipped screw rod — delivering smooth, accurate linear motion in a tiny, portable form factor. Ideal for hobbyists, engineers, and makers building small-scale automation, robotics, camera sliders, or precision positioning systems.
Key Features
- Planetary Gear Reducer: Integrated deceleration gearbox for increased torque and smooth, controlled movement
- Precision Ball Bearing: Mounted at the top of the screw rod for reduced friction and longer service life
- 2-Phase 4-Wire Stepper Design: Enables precise step-by-step positioning with excellent repeatability
- 12mm Maximum Stroke: Sliding table travel up to 12mm — perfect for fine linear displacement applications

Frequently Asked Questions
Q: What voltage does this mini linear actuator stepper motor require?
A: This mini linear actuator operates on DC 3V power. It is compatible with common microcontrollers (such as Arduino or Raspberry Pi) and small-scale DIY electronics projects that use low-voltage DC power supplies.
Q: What is the maximum linear stroke of the sliding table?
A: The sliding table has a maximum stroke of 12mm. This makes it well-suited for fine precision positioning tasks, such as camera focus sliders, miniature CNC stages, or small robotic actuators requiring short, accurate linear travel.
Q: What are the two available sizes/styles?
A: There are two style options available: 34×5mm and 34×4.5mm. Both feature the same 2-phase 4-wire stepper motor with planetary gear reducer and precision ball bearing screw rod — choose the size that best fits your project's dimensional requirements.
Q: Is this stepper motor suitable for beginners?
A: Yes. The motor's simple 4-wire interface makes it easy to connect to standard stepper motor driver modules. Its compact size and low operating voltage make it an excellent choice for both beginner makers and experienced engineers working on small automation or robotics projects.
