N20-1218 Worm Gear DC Motor with Hall Encoder | 3V 6V 12V Micro Gear Reduction Motor for Smart Car Robot

Product Overview

The N20-1218 Worm Gear DC Motor is equipped with a high-precision Hall encoder, integrating self-locking worm gear, reduction transmission and position feedback functions. It is a compact, high-torque micro motor designed for smart cars, small robots, DIY electronic projects and precision motion control equipment. Compatible with 3V, 6V, 12V DC power supply, it provides stable low-speed operation and accurate position detection, meeting the needs of various small-scale drive scenarios.

Key Features

  • Built-in Hall Encoder: Equipped with high-precision Hall encoder, which can accurately detect the rotation speed, angle and position of the motor, realizing precise motion control and closed-loop feedback.
  • Self-Locking Worm Gear Design: Adopts worm and worm gear transmission structure, which has excellent self-locking performance, can prevent reverse rotation and hold position stably when the power is cut off, suitable for scenarios requiring position retention (such as robot arms, smart car steering).
  • Wide Voltage Compatibility: Supports 3V, 6V, 12V DC power input, flexible to match different power supplies, applicable to various DIY projects and small electronic devices.
  • Low Speed & High Torque: Optimized gear reduction ratio ensures stable low-speed output and strong torque, effectively improving the load capacity of the motor, suitable for precision drive and heavy-load small mechanisms.
  • Compact & Durable: Miniature N20 size, small volume and light weight, easy to install and integrate into space-limited devices (such as smart cars, micro robots); high-quality metal gears and motor core, wear-resistant and durable, ensuring long service life.
  • Easy to Use: Simple wiring, matching standard connectors, convenient for quick assembly and debugging, suitable for both beginners and professional DIY enthusiasts.

Applications

  • Smart robot cars, AGV small vehicles, and remote control cars
  • DIY robots, robotic arms, and precision motion control mechanisms
  • Electronic teaching aids, scientific research experimental equipment
  • Small medical equipment, precision instruments, and automatic control devices
  • Various DIY electronic projects and small mechanical drive systems

Great quality case, keyboard doesn’t work as intended
Color: Dark Cherry
Case is fine and good quality but the keyboard doesn’t work as intended. Bluetooth connects great but the keyboard is formatted incorrectly. For example, when I try to use a dash, it puts an apostrophe instead. I have no idea how to reformat it myself. I’d love just a replacement keyboard

Great buy! Worth the money and the color is nice. The keyboard works, some buttons I haven’t figured out but for the most part it’s worth the purchase!

Great quality case and keyboard
Color: Purple, Color: Purple
Super good quality case, I was actually surprised since it’s such a good price. It fit my 10.9 inch perfectly! Keyboard has magnetic attachment to the case which is super handy, and it connected with Bluetooth seamlessly. Keyboard isn’t silent, it’s on the louder side, but not too loud at all and it doesn’t bother me at all because I prefer clickier keyboards. Oh also something that’s really cool is that you can change the colors of the keyboard, love that!
