Engineering Overview

Equipped with iron-free coreless rotor and 5-segment commutator combined with precious metal brushes, the FA-1320R effectively eliminates cogging torque to achieve ultra-smooth rotation and low vibration. With moderate rotor inertia and stable dynamic performance, it works reliably in compact devices. The optional G13MF and G13XL gearboxes and encoders can be installed to enhance torque output and realize closed-loop precision control, adapting to diverse micro drive application scenarios.

Typical Applications:
• Portable handheld precision medical instruments
• Professional mini cosmetic and beauty equipment
• Small precision liquid and air micro pumps
• Compact laboratory testing and analytical devices
