Mini 6mm Planetary Gear Stepper Motor 30mm Linear Slider

Mini 6mm Planetary Gear Stepper Motor with 30mm Linear Screw Slider Actuator

Take your precision motion control projects to the next level with this compact 2-phase, 4-wire miniature stepper motor paired with a precision linear screw slider actuator. Featuring a 6mm planetary reduction gearbox and a smooth-running slide table with a 30mm maximum stroke, this unit is ideal for DIY robotics, automation builds, camera sliders, lab equipment, and micro-positioning applications.

How It Works

The stepper motor drives through the planetary reduction gearbox, which in turn moves the precision screw slider up or down with exceptional positional accuracy. With a resolution of just 0.0052 mm per pulse, this actuator delivers repeatable, high-precision linear motion. Operation is notably quiet, making it well-suited for noise-sensitive environments.

Important: This motor requires an external stepper motor driver and controller to operate. Due to the planetary gearbox design, the slide table is optimized for low-speed, high-precision movement rather than fast travel. Keep operating current at or below 0.14 A to avoid motor overheating.

Ideal Applications

• Robotics & automation projects
• Micro-positioning stages
• Camera focus & slider systems
• Laboratory & scientific instruments
• DIY CNC & maker builds
• Arduino / Raspberry Pi motion control

Frequently Asked Questions

Q: Does this stepper motor come with a driver or controller?

A: No, the 6mm planetary gear stepper motor and linear slider actuator require an external stepper motor driver and controller to operate. Please ensure you have a compatible driver before purchasing.

Q: What is the maximum stroke of the linear slider actuator?

A: The maximum stroke of the sliding table is approximately 30 mm, requiring about 5,800 pulse signals to complete the full travel distance, with a resolution of ~0.0052 mm per pulse.

Q: What current should I set on my driver for this motor?

A: It is recommended to operate the motor at approximately 0.14 A. Running the motor at 0.28 A or higher may cause it to overheat. Always start at lower current settings and test before increasing.

Q: Can this motor move the slider quickly?

A: Due to the planetary gearbox design, the slider actuator is optimized for low-speed, high-precision linear motion. It is best suited for applications requiring accuracy and repeatability rather than high-speed travel.

Q: Is this compatible with Arduino or Raspberry Pi?

A: Yes, with an appropriate stepper motor driver module (such as A4988 or DRV8825), this actuator can be controlled via Arduino, Raspberry Pi, or similar microcontroller platforms for maker and robotics projects.
