Frequently Asked Questions

Q: What is a DC3V planetary gear mini push rod motor / linear actuator?

A: A DC3V planetary gear mini push rod motor is a compact electromechanical device that converts rotary motor motion into linear (straight-line) push or pull movement via a precision screw drive. The planetary gear stage reduces motor speed while increasing output torque, enabling precise, controlled positioning. This unit features a 12mm maximum stroke and operates at DC 3V, making it ideal for low-voltage electronics and automation projects.

Q: What projects or applications is this mini linear actuator suitable for?

A: This mini linear actuator is highly versatile. Common applications include robotics arms, micro-positioning stages, camera sliders, small automated valves, optical lens adjusters, DIY automation with Arduino or Raspberry Pi, and any project requiring precise, repeatable linear motion in a compact footprint. Its wide applicability and small size make it a go-to component for makers and engineers alike.

Q: How do I connect and power this DC3V push rod motor?

A: Simply connect the motor's leads to a regulated DC 3V power source or a compatible microcontroller output (e.g., via an H-bridge motor driver for directional control). Polarity determines the direction of linear travel — reversing the supply polarity reverses the push/pull direction. Always ensure your power supply is regulated and within the 3V operating range to protect the motor and extend its service life.

Q: What are the two available style options for this motor?

A: This mini push rod motor is available in two size variants: 34 × 5mm and 34 × 4.5mm shaft/barrel configurations. Select the style that best fits your mechanical design or mounting requirements. Both styles share the same core planetary gear deceleration and screw linear actuator functionality.
