Quantity

`3V N20 DC Gear Motor with Hall Encoder, 1:50 Ratio, for Smart Balance Cars`

`12V N20 Micro Encoder Motor, 3-Wire AB Phase, for Camera Jib Arms`

Product Overview

The CHF-GM12-N20 ABHL DC Hall Encoder Gear Motor is a compact, lightweight motor designed for small-scale robotics and automation projects. Featuring an AB-phase Hall encoder for closed-loop speed/position feedback, it’s ideal for smart balance cars, line-tracking robots, and camera pan-tilt systems.

Key Features

Built-in Hall Encoder: AB dual-phase incremental encoder provides precise speed/position feedback (3-wire, 3.3V/5.0V signal compatible).

Wide Voltage Compatibility: Supports DC 3-12V operation, with options for 3V/6V/12V rated versions.

Multiple Gear Ratios: Choose from 1:10 to 1:380 to customize speed and torque for your project.

Compact & Lightweight: Only ~13g, with a 3mm D-shaped shaft (10mm length) for space-constrained applications.

Optional Mounting Bracket: Available with a bracket for easy installation in fixed setups.
