Stepper Motor Linear Screw Shaft 13-Tooth Plastic Gear DIY Kit

Upgrade your DIY electronics and automation projects with this compact Stepping Motor Linear Screw Shaft Rod Block with 13-Tooth Plastic Gear. Designed for precision motion control, this miniature 2-phase, 4-wire stepper motor is ideal for makers, hobbyists, and engineers who need reliable linear or rotational movement in a small form factor.

The output shaft features a worm gear drive that meshes with the gear assembly to create a smooth worm gear reduction transmission. With a reduction ratio of 1:9.5 and a stepping angle of 18 degrees per step (just two pulses for a full 360° rotation), this motor delivers precise, repeatable positioning for your custom builds.

Frequently Asked Questions

Q: What type of stepper motor is this and how does the worm gear system work?

A: This is a 2-phase, 4-wire stepper motor with a worm gear output shaft. The worm gear drives the 13-tooth plastic gear to rotate, forming a worm gear reduction transmission with a 1:9.5 reduction ratio. This means the output rotates more slowly than the motor, providing increased torque and precise positional control for your DIY projects.

Q: What is the stepping angle and how many pulses are needed for a full rotation?

A: The stepping angle of this motor is 18 degrees per step. Because of this, only two pulses are needed to achieve a full 360-degree rotation, making it straightforward to program with microcontrollers like Arduino or Raspberry Pi using standard stepper driver modules.

Q: What projects is this stepping motor linear screw shaft kit best suited for?

A: This component is ideal for compact DIY automation builds such as camera monitor sliders, miniature robotic actuators, 3D printer auxiliary axes, automated focus controls, and small CNC linear stages. Its 15mm form factor and worm gear reduction make it particularly well-suited for applications requiring precise, low-speed linear or rotational motion in a tight space.

Q: Is this compatible with standard stepper motor driver boards?

A: Yes. As a standard 2-phase, 4-wire stepper motor, it is compatible with widely available stepper driver modules such as the ULN2003, A4988, DRV8825, and similar boards commonly used in Arduino and Raspberry Pi projects.
