An integrated encoder enables closed-loop speed control and position feedback, while multiple reduction ratios support controlled low-speed movement in miniature robotics, smart locks, and automation equipment.
The motor integrates an N20 brushed DC motor, compact gearbox and rear-mounted encoder into one miniature drive assembly.

This model is built on a mature N20 gearbox structure, supporting reliable mechanical consistency.
Clear and consistent size definitions help reduce integration uncertainty during product development.
The rear-mounted encoder provides motion feedback for speed monitoring and closed-loop motor control in compact applications.
The motor, gearbox and encoder are integrated into one compact assembly, reducing separate installation and alignment work.
