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.
