N20-1218 Self-Locking Worm Gear DC Motor | 3V/6V/12V Micro Low-Speed Motor for Smart Robots & Cars

Product Overview


The N20-1218 self-locking worm gear DC motor is a compact, high-torque micro motor designed for smart vehicles, robotics, and precision low-speed drive systems. It supports 3V, 6V, and 12V DC power inputs, delivering stable low-speed rotation with reliable self-locking capability.

Key Features

  • Self-Locking Worm Gear Design: Prevents back-driving, holds position when power is off, ideal for robotic arms and smart car steering systems.
  • Wide Voltage Compatibility: Works with 3V, 6V, and 12V DC power supplies, flexible for various small-scale electronic projects.
  • Low-Speed & High Torque: Optimized gear reduction provides steady low-speed output with strong torque, suitable for precise motion control.
  • Compact Size: Miniature N20 form factor, easy to integrate into smart cars, robots, and other space-limited devices.
  • Durable Construction: Sturdy metal gears and high-quality motor core ensure long service life under continuous operation.

Applications

  • Smart robot cars & AGV vehicles
  • Robotic arm joints & precision actuators
  • DIY electronic projects & educational robotics
  • Small mechanical drives & slow-motion mechanisms
