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

Fat pillows
Size: Queen - Pack of 2, Style: Soft, Configuration: Pillow
Super overstuffed pillows. Took some of the batting out, and it was more comfortable. I would buy them again.

Pillows
Size: Queen - Pack of 2, Style: Soft, Configuration: Pillow
Pretty decent for the price. Along with its conventional use, those pillows are pretty comfy to sit on. Pillows are for more than just sleeping; they’re excellent seat cushions!

Lumpy!

These are horribly lumpy! The filling clumps. They won’t lay flat.
This is after working with them to try to ref, fluff them
Terrible product

A true medium firm pillow
Size: Queen - Pack of 2, Style: Soft, Configuration: Pillow
I like a medium pillow that lets my head sink in a little bit so my neck isn't cranked at an angle but not to the point where it sinks in completely. You can also scrunch it a little bit. Also love that it's queen size, as most queen sheet sets for come with queen pillow cases, not standard. I am surprised it worked out, very happy with it.
