Description of Threaded Shaft Encoder N20 DC Motor 12V 300RPM

The Threaded Shaft Encoder N20 DC Motor is a compact, high-efficiency motor equipped with a 300 RPM brushed DC gear motor and an integrated M3 threaded lead screw (55mm long). Designed for generating precise linear motion, this motor allows a nut to travel linearly along the screw as the shaft rotates. Its small form factor makes it an ideal solution for use in robotics, automation, linear actuators, and space-constrained mechanical systems.

This plug-and-play unit is compatible with popular microcontrollers such as Arduino, Raspberry Pi, and others when used with an H-bridge driver module. Its high-torque performance and reliable construction make it suitable for both prototyping and embedded applications.

Note: Shaft play is expected when the lead screw is unsupported on one end. For stability, use a mount or bearing to secure the free end.


Key Features


  • Compact brushed DC motor with integrated spur gearbox
  • High-precision M3 x 55mm threaded shaft for linear actuation
  • Copper-plated gear case with robust internal gearing
  • Sleeve bronze bushings for enhanced wear resistance
  • Supports bidirectional rotation (CW & CCW)
  • Easy integration with microcontrollers via motor drivers

Frequently Asked Questions (FAQ)


What type of motion does this motor generate?
This motor generates linear motion by rotating a threaded M3 lead screw. When a nut is attached to the screw, it moves linearly as the shaft spins.

Can I use this motor with an Arduino or Raspberry Pi?
Yes, it can be used with Arduino, Raspberry Pi, or other microcontrollers when connected through a motor driver such as an H-bridge (e.g., L298N or L9110).

Does the motor support bidirectional rotation?
Yes, it supports both clockwise (CW) and counterclockwise (CCW) rotation, allowing linear motion in both directions.

Is shaft play normal during rotation?
Yes, slight shaft play is normal if the lead screw is not supported at both ends. Using a bearing or shaft mount will reduce this movement and improve stability.

What kind of applications is this motor suitable for?
It is ideal for robot arms, linear sliders, mechanical locks, electric valves, camera rails, and other small-scale automation systems requiring linear motion.
